Donna CampbellEditor in ChiefEQUIPMENT MATTERSThis month’s issue focuses on equipment. I’m a big fan of equipment, tools, and digital apps. The construction industry has truly evolved over the years, and COVID-19 has certainly added to strengthened safety protocols and communication efforts. For many, it’s a new frontier on the construction horizon. With projects still underway in many parts of the U.S., equipment varies, and so do the articles this month as we highlight Curb Roller Manufacturing (pg 14) and Topcon’s Automatic Excavator System (pg 18). From cobble stone pavers being used to redo streets in a community (pg 22) to the maturity of utility detection in heavy construction (pg 36), the jobsites today are works of art. And, there is always room for improvement. Check out the article on proactive problem prevention by Christine Corelli (pg 38) and the legal article on business retooling (pg 44).For commentary from the frontline, five questions were asked of The BILCO Company’s general manager, Mike Toohey; see What’s Trending on page 62. Finally, a huge THANK YOU to those that attended the premier MCS virtual expo this month; I hope the attendees learned what’s new from our wonderful sponsors and exhibitors. A special thanks to Caterpillar, Milwaukee Tool, Case, Hilti North America, InEight, and construction industry thought leaders Randy Goruk and Wally Adamchik for contributing to the webinar/podcast educational section of the expo; their help was greatly appreciated.

AUGUST 2020 www.mcsmag.com14project profileReady to Rollhow 1,000 pounds of spinning metal changed the Missouri ditch liner industryPROJECT INNOVATION SUCCESSPART 1 OF 2
www.mcsmag.com AUGUST 202015Near the Kansas City International Airport lies a well-traveled stretch of road that connects NE Cookingham Drive to I-435. A 20-mile jaunt separates the airport from downtown Kansas City, and while some drivers might make their way via the direct I-29 route, others choose the I-435 route that might take a little longer but sees less traffic. If drivers happened to take the Cookingham/I-435 route during late summer 2019, they may have caught a glimpse of an impressive road construction project and some never-before-seen equipment. The construction site was home to a 24-foot-wide, 1,000-pound rolling tube of steel. And a real head-turner it was.THE PROBLEMThe onramp that connects Cookingham Drive to I-435 appears to the naked eye to be a standard ramp, but the positioning of the onramp and the surrounding area were causing headaches for the Missouri Department of Transportation (MoDOT). A field that runs parallel to the ramp often produces significant rainwater runoff that makes its way onto the onramp. In a usual case, rainwater and subsequent runoff don’t pose huge issues for highways and ramps, but this was a different story. Sedimentary dirt and debris filled the south side of the ditch and the onramp. As the ditch filled up with sediment and dirt carried by the runoff, the material would spill over onto the south lane of the onramp. This presented slippery, dangerous situations for drivers heading for the interstate at 55-60 mph. To combat the issue, MoDOT maintenance crews used heavy-duty equipment to tackle the buildup, closing the onramp every few years to clear the ditch and roadway with skid steers, track hoes, and several haul trucks. Last time they cleaned it, they shut down the onramp for 2 days to complete the cleaning. This method solved the problem temporarily but created headaches for drivers and a lot of unnecessary work for crews.MoDOT tried incorporating pre-shaped paved flumes to carry the rainwater, but the flumes filled up just as quickly as the unpaved ditch and required just as much cleaning. MoDOT contemplated installing a rock-based lining, but research showed the quickly accumulating rainwater would likely carry the rocks away. MoDOT continued to search for a viable solution to address the maintenance problem and finally found a permanent answer as part of a large concrete patching job on the roadway. UNIQUE SOLUTIONIn the early summer of 2019, Realm Construction was subcontracted to patch the concrete on Cookingham Drive and the onramp to I-435. Manager of Field Operations Russ Stark and his team specialize in concrete patchwork. They completed that portion of the job and then sat down to find a way to tackle the ditch liner, which was a concrete project they were less familiar with.Stark, who has worked for Realm for more than 11 years, needed to find a solution that would stay within the budget and the assigned timeframe. The mission was to essentially line the
AUGUST 2020 www.mcsmag.com16project profileditch with concrete, and Stark initially only knew of one conventional method to accomplish it. That method was to form the ditch in a sectional approach. This could be done either by pouring the bottom concrete and pulling a tube or screed up by hand, or pouring it transverse—coming down the slope to the bottom and then back up. Crews would pour one 20-foot bay, skip a 20-foot area, pour another 20-foot bay and so on. The next day, after the bays dried, crews could fill in the alternating empty areas. While this method is inexpensive and proven, it is time consuming and physically taxing.“If we approached this project the conventional way, we’d only be able to pour about four bays a day, which is 80 feet of ditch liner a day,” Stark says. “At that rate, the project would have taken us 15-20 days. I knew we could do it quicker than that.”Stark’s ultimate solution would include an approach that might end up with a higher initial equipment cost. But could that additional investment in equipment end up saving him time and money? Stark proposed commissioning a large metal flume drum from Curb Roller Manufacturing. The company is known for their hydraulic- and battery-powered concrete roller screeds, but also manufactures custom-sized rolling drums. The drums are commonly used for pouring streets, medians, v-gutters or flumes, and while the company prides itself on creating custom solutions, this drum exceeded the size of any created in the past. “I had seen a ditch liner drum on a different project a year prior and asked the contractor—Clarkson Construction—who made it,” Stark says. “It was only about 14 feet wide and I knew we’d need something nearly double that size. But I thought it could work.”Curb Roller Manufacturing, based out of Fairview, Kansas, has been serving all industries from landscapers to government entities for more than 10 years. When Realm Construction approached them with the custom request, they were eager to engineer a solution.PROJECT STIPULATION The contractors were also ready to begin the project, but delivering an oversized custom drum to a jobsite had its obstacles. First, Stark had to get approval from MoDOT to implement this unique equipment and process. He presented his case, highlighting the potential for a better finished product and a significantly improved timeline.Matt Daulton, MoDOT resident engineer for the project, reviewed Stark’s proposal and approved with one stipulation—using the Curb Roller couldn’t increase the overall cost of the project.“We try to encourage innovation on every project,” Daulton says. “I had never seen something like this, but our contractors and manufacturers in the industry often have new ideas and the best answers. So, we were open to it.”After gaining clearance from MoDOT, Stark and his team had to work with the grading and excavation subcontractor who was preparing the ditch. The original design of the ditch, before implementing the Curb Roller idea, included varying widths and a flat bottom. This approach would save grading and excavating costs on a traditional concrete project, but the Curb Roller method would require a consistent width to successfully lay concrete. Stark was convinced that the extra cost in grading and excavating would make up for itself in the time savings down the line. If the crews had done the whole project by hand, there would have been an increased potential for neck, knee, and back injuries along the way.
www.mcsmag.com AUGUST 202017“I knew that this would create a more uniform product, which would be easier for MoDOT maintenance to clean out,” Stark says. “The original cross section of the ditch had varying slope widths and lengths through the entire 1,600-foot-long ditch liner. So, we had to get the grading team to adjust and create a consistent canvas for the concrete.”While the grading and excavating teams prepared the base, Stark worked with Curb Roller Manufacturing to design and craft the perfect flume drum. HERE COMES THE DRUMKraig Pyle, general manager of Curb Roller Manufacturing, worked with Stark throughout the planning process. While the company specializes in custom drums, they’d never designed something of this magnitude before.“We had designed drums as long and as large in diameter, but never with this kind of combination,” Pyle says. “This was so impressive because it had such a large pan and slope wings. We know the capabilities of our product and we were confident taking on this challenge. We knew that with a few adjustments and alterations, we could pull this off and save the contractor time and labor.” Stark officially submitted his order to Curb Roller Manufacturing: a 24-foot wide, 1,000-pound hollow rolling flume drum. He calculated the required slope of the sides of the ditch according to MoDOT requirements. Each wing section of the drum was 8 feet wide, with an 8-foot flat pan section in the middle. The drum was 52 inches in diameter with 4:1 backslopes. Since the ditch liner itself is 2 feet deep, they achieved a 25-degree rise by implementing a 1-foot drop for every 4-foot run.CLOSING THOUGHTPyle sent Stark a design of the product, which he promptly approved. The company delivered the drum to the jobsite just 5 days later. Look for part 2 of this article in the next issue of MCS as the project unfolds and the savings are discovered. for more informationCurb Roller Manufacturing has been the world leader in shaped concrete roller screeds for more than 10 years.

AUGUST 2020 www.mcsmag.com18project profileComplex Made Simpleautomatic excavator system provides design and position DESIGNED TO OPTIMIZEBy Jeff Winke
www.mcsmag.com AUGUST 202019The history of the construction excavator goes back quite some time. The very first excavator is said to have been built in 1882 by Sir W. G. Armstrong & Company in England, where it was used in the construction of Port of Hull docks. Unlike today’s excavators that use hydraulic fluid, water was used to operate the hydraulic functions back then. It was not a true hydraulic machine, but an approximation that used cables to operate the bucket, and with a hydraulic cylinder operating a set of multiplying sheaves. The idea on Sir W. G. Armstrong’s machine was not successful, nor were machines of somewhat similar design, which followed and were built into the start of the 20th century.INNOVATION IN DESIGNThese first excavators and successors that were developed and evolved well into the 1990’s are virtual dinosaurs when compared to the sophisticated machines available for the mining, construction, and utility markets today. Today, construction equipment manufacturers have an emphasis on developing technologically advanced and efficient excavators that are designed to be more productive. Manufacturers are also trying to meet the propelling growth of the global excavator market. From large construction areas to small jobs in tight areas, there are a wide range of excavators to meet the needs of any construction job. Conventional tail swing models are designed to offer increased side and lifting stability, while the minimum tail swing models are designed for jobs in tight quarters, with no room for wasted movement. All technologically-advanced excavators are designed to optimize the material moving process in the construction industry. AUTOMATED CONTROLThere have also been developments in how heavy equipment is controlled. Automated control has changed the earthmoving process with GPS machine control systems governing motor graders and dozers.

AUGUST 2020 www.mcsmag.com22project profileBuilt along the edges of several canals in Foster City, California, the Island J complex has been compared to Santorini, Greece, for its flat roofs and linear patterns, as well as its quaint cobblestone streets. When the city was developed 60 years ago, the architect insisted on having design freedom over what is now the Island J complex, making it unique from surrounding neighborhoods. However, over time, its once beautiful streets have been through numerous repair projects aimed at replacing broken cobblestones at the lowest possible cost. The result was a patchwork of stone, concrete, and asphalt that not only detracted from Island J’s overall aesthetic and equity, but also created flooding and safety concerns for its residents. The Island J Homeowner’s Association (HOA) recently underwent a $2 million project to replace all 100,000 square feet of its roadways with Belgard’s Cambridge Cobble in Tuscana color. As a result, the community has seen the return of its timeless aesthetic and an increase in overall equity. “Residents have always asked if we could return to pavers instead of asphalt, but all previous estimates we received just put that dream out of reach,” explains Bart Besseling, Island J HOA president. “So, we saved for 10 years to have enough money to replace the roads with asphalt and then spoke with several contractors.”FINDING THE SOLUTIONAmong the companies Besseling contacted was Modern Paving; the company’s vice president, David Tetrault, explains they didn’t work on asphalt projects. However, after discussing the parameters of the project he provided an estimate for using pavers. “After talking to him, we were surprised and thrilled to find out we actually could afford to restore the beautiful look of pavers to the community for less than we’d saved for the asphalt,” says Besseling.The commercial-thickness (80mm) pavers are a special order, manufactured in Belgard’s facility in nearby Stockton, California. The fact that Belgard could deliver them within 4 to 6 weeks, more quickly than other companies who bid on the project, was also a key selling feature. “We could start work within the desired timeframe because we didn’t have to wait for material,” says Tetrault. FUTURISTIC CITY CONCEPTFoster City, California, was an engineering feat, developed—or, more literally, was filled, formed, and constructed—in 1958. The city’s concept was considered so unique and futuristic at the time that models and artists’ renderings of it were displayed at the Modern Art Museum in San Francisco. Developer T. Jack Foster and his sons purchased 4 square-miles of land known as Brewer’s Island and set out to build a new city from scratch over the mud flats of the San Francisco Bay. The island was situated at mean sea level, so surface elevation needed to be raised 4 to 5 feet. To accomplish this, 14 million cubic yards of sand was pumped from San Francisco Bay onto Brewer’s Island over the course of 6 years (24 hours a day, 7 days a week). A central drainage basin from which water could be pumped back into the Bay was also created. This now serves as Foster City’s beautiful lagoon, a centerpiece on which residents and visitors alike enjoy numerous recreational activities. RESTORING THE STREETSAs the city’s original streets eroded and were replaced with large, flat asphalt surfaces, the struggle against water resurfaced. After significant rainfall, several homes in the community would have large puddles in the front yard for weeks until the ground could soak it back up. “The streets had become bumpy over time, so this new project gave us a chance to level everything out and also correct the slopes for better drainage,” says Besseling.The streets of Island J were in fact long overdue for maintenance and repair; previous HOA boards had neglected to do reserve studies to schedule and pay for it. “When this board came in during the early 2000s, we found we were $5 million dollars behind in maintenance for all components,” explains Besseling. “We spent several years mitigating other issues, and the streets are the last of these overdue projects we’re tackling.”Tetrault and his team provided a very comprehensive presentation for the HOA Mitigate Floodingrestoring original charm with cobble paversICONIC ISLAND COMMUNITY
www.mcsmag.com AUGUST 202023that laid out how they would install the paver system. Besseling notes, “The quality of their work and work ethic of their personnel was very clear from that presentation and we were happy to move forward with them.”The HOA chose Belgard’s Cambridge Cobble in Tuscana color because it complemented the Islands’ bright color scheme of white, blue, and yellow properties. “The homes are the equity, so we didn’t want to draw attention away from them, but rather to blend nicely with them,” says Besseling.STRUCTURAL CONSIDERATIONSAlthough choosing the design aesthetic for the roadways was easy enough, there were many structural considerations. Tetrault recommends using geotextile fabric between the soil and the paver system “to keep the system independent of what’s going on beneath it,” he says. He also specified the commercial-grade pavers because of The Islands’ resident traffic, as well as a lot of heavy truck traffic. The area is comprised of several, narrow and curvy streets that Foster City fire and police use as a monthly training route, and garbage and recycling trucks come through twice a week.To minimize negative impact on The Islands’ residents during installation, Modern Paving and the HOA came up with a well-organized plan. Modern Paving worked on a small stretch of street at a time, including one of several parking lots. Work began after people left for the workday and stopped at five o’clock. Even mail was rescheduled to be delivered after five. A ramp would allow people to drive over the work area to their homes. “We say it’s a temporary inconvenience for a permanent improvement,” says Besseling. With more than half the installation complete, the new roads look better, provide better drainage and even improve residents’ safety. “The asphalt roads felt like a freeway, so people drove at freeway speeds,” explains Besseling. “We have a lot of young families in this community and kids play in the streets, so it became a concern. Pavers automatically make people drive more slowly.”CLOSING THOUGHTThe project also offers a good return on investment with increased property values. On average, the units in The Islands sell for approximately $1.2 million. “Having new, sturdy, and good-looking roads increases the equity of the entire HOA, which will also positively impact the value of each unit,” says Besseling. for more informationBelgard, part of Oldcastle APG, offers a complete collection of paver and wall products for outdoor living spaces, walkways, driveways, parking areas, and retaining walls.

Now, multiply that by the number of chains that may be needed to adequately secure a load and you can be talking about a lot of cumulative weight.“We use a different amount of chain for each load depending on the load weight and available securement points,” says Ace Carter, engineer for Northwest Logistics Heavy Haul, an Oklahoma-based heavy-haul service provider doing business throughout the U.S. and Canada. “A theoretical load requiring 14, 30-foot, half-inch 100-grade steel chains and binders with a 15,000-pound working load limit (WLL), would add up to about 1,372 pounds of securement, and simply deploying this is a long and strenuous task for even a two-man crew.SECURING CARGOOnce the chains are situated around a trailer and its cargo, the real work begins. Some cargo items have engineered anchor points that enable workers to connect load securement devices directly to the cargo and this is known as “direct” securement. Other cargo articles have nothing to attach to, so the securement has to pass through, over, or around the article, and this is known as “indirect” securement.Carter says that on larger loads like tanks, a team of two would generally be used to secure the load. One person usually throws a guide rope, attached to the chain, over the tank to a second person on the opposite side of the trailer, who then pulls the chain up and over the vessel as the first helps guide it. “Either way,” Carter says, “steel chains take time to set and secure and it’s physically demanding work.Steel chains aren’t just heavy, they can be abrasive as well, and when using them, Northwest often had to use carpet, rubber, fire hose, and other liners to protect the cargo’s finish from being damaged. The process sometimes required climbing ladders and the use of manlifts or forklift baskets, and there were more materials to buy, transport, store, and maintain. More care was also required when handling, orienting, and securing heavy chains, to avoid damage to payloads that could ultimately result in customer dissatisfaction. THE MISSING LINKSIn late 2018, Carter and Northwest began exploring a new cargo securement technology from Doleco USA that promised to alleviate some of the issues surrounding the use of steel chains for cargo securement. Doleco’s new product had the potential to change not only Northwest’s approach to load securement with steel chains, but the ubiquitous use of steel chains across the entire heavy-haul industry. Doleco’s revolutionary DoNova® PowerLash Textile Lashing Chain and Tie Down System is made of high-performance Dyneema® fiber. Dyneema’s ultra-high-molecular-weight polyethylene (UHMWPE) material is 15 times stronger than steel by weight, and made into chain, up to 85 percent lighter—so lightweight, in fact, that it floats on water. “The DoNova PowerLash Textile Lashing Chain has extremely low moisture absorption, is self-lubricating, is highly resistant to corrosive chemicals, and is 15 percent more resistant to abrasion than carbon steel,” says Ralph Abato, president and managing director of Doleco USA. “The textile chain is available with a WLL as high as 22,000 pounds, more than that of half-inch steel chain and just under the 22,600-pound WLL of 5/8-inch steel chain.”Since the DoNova PowerLash Textile Lashing Chain in the same 30-foot lengths weighed 85 percent less than the half-inch steel chains they would replace, Northwest’s crews needed only 10 DoNova PowerLash Tiedowns to do the job of 14 steel chains. Coupled with other tangible benefits, Northwest decided to give the DoNova product a try.
AUGUST 2020 www.mcsmag.com28equipment solution“Carrying the lightweight DoNova chains from their storage location on the truck or support vehicle to every point of securement on the trailer now requires much less effort. Less weight means easier handling, less fatigue, and a lower potential for injury,” Carter says. “It is safe to say that the workers love the product.”Carter notes that now his folks can toss the guide rope over and pull the lightweight DoNova PowerLash Textile Lashing Chain over a tank and secure both sides, without worrying about scratching the tank’s finish. He believes that DoNova chains save time and effort while reducing worker fatigue and risk of injury.“Time savings is likely less significant than weight savings and increased capacity,” Carter says. “Now we have less effort required for securement, less risk of personal injury, less gross weight to haul and permit, fewer securement devices required on some loads, and the 10-metric-ton-capacity matches securement points on many of our European trailers.”CHAIN-GING THE PROCESSSecuring cargo on an open-deck trailer can be daunting at times. Construction materials and equipment in particular present unique challenges. Those securing cargo and vehicle operators must be familiar with federal regulations and must have a working knowledge of the physics of how cargo behaves once it’s in motion.Depending on the type of load and the requisite securement method called for, those doing the securing have a number of decisions to make. Some cargo types are simpler than others and some are downright complicated, requiring significant physical effort. Some loads may be heavy, have sharp edges or be prone to shifting. Climbing into, onto, and around items in order to attach restraints can expose workers to a host of hazards.“Maybe your heavy-haul drop deck or lowboy trailer is carrying large or articulating equipment to and from an off-highway worksite, Abato says. “If so, you have to know that any and all hydraulic arms need to be secured, and that any dirt and rocks left on the deck may be considered ‘unsecured cargo’ by the authorities.”The point is, that replacing heavy steel chains with DoNova PowerLash Textile Chains makes life easier and less complicated, and gives fleets and owner-operators one less thing to worry about.The extremely low weight and flexibility of DoNova PowerLash chain promotes easier handling of heavy-duty load securing devices. It can be easily thrown over even large loads or guided around complex cargo geometries without damaging them or their finish. With DoNova, individual workers can handle long lashing chains of more than 60 feet all by themselves. The textile chains can also be shortened very quickly since all hooks of the tensioning device can be attached directly to the flexible chain links. This chain is particularly well suited for heavy use since it is extremely resistant to abrasion, chemicals, and even seawater.
www.mcsmag.com AUGUST 202029CHAIN ELEMENTSSpecial load binders have also been developed for the DoNova Textile Chain. At just three quarters as long as a standard load binder, the DoRa® Ratcheting Load Binder fits into tighter spaces, but expands to enable users to reach twice as far as any other. The compact size and extra length of the DoRa save users time and trouble, because they don’t have to detach and reattach chains when periodically retensioning cargo.“Doleco’s DoRa Ratcheting Load Binder is 20 percent shorter than others, extends to twice their length and makes chain retensioning a breeze. Abato shares, “The patented spindle-in-a-spindle design of the DoRa Ratcheting Load Binder saves time, giving users unrivaled tensioning capabilities when securing cargo with steel chains, but is designed specifically to work as a system with Doleco’s DoNova PowerLash Textile Lashing Chain.With its WLL of 22,000 pounds, the DoNova PowerLash 25/8 may be used with the lashing strap as a tensioning element. Doleco’s Heavy Duty 2-inch Ratchet with Gear Drive, webbing made with Dyneema, features special eye-hooks and coupling links can substitute for standard load binders, and gives the load securement system an increased tensioning range at a reduced weight. The WLL of the tensioning elements employed (straight pull or loop) are easily matched to the WLL of the textile chain and hooks effortlessly into their respective chain elements. DoNova can also be used as a head sling. If a load has no fastening points, it can be secured with a sling that runs over and/or around the cargo. This indirect lashing method allows even the most unwieldy load to be brought under control.“The DoNova PowerLash head sling not only secures voluminous loads without lashing points, it also functions as a headboard substitute for loads that can’t be placed against the actual headboard of the vehicle,” Abato says. “DoNova can be guided around the load flexibly and tensioned with lashing straps that are hooked directly to the chain links.”CLOSING THOUGHTFew new products offer the quantity of dramatic advantages delivered by Doleco’s advanced textile chain technology. The contrast between steel chain and the DoNova PowerLash Textile Chain is quite tangible.“All I have to do is let folks hold a steel chain in their bare hand and a DoNova Textile Chain in the other,” says Abato. “People immediately understand that this is an advancement in material engineering and industrial design that will have implications that extend far beyond cargo securement. There’s almost always a slight look of awe on their face.” OSHA Compliant Guardrail andStair Rail SystemsSafety Boot® Guardrail SystemStringerShield® Stair Rail System1.800.804.4741safetyboot.com• Non-Penetrating Design• Rugged Steel Construction• Exceeds OSHA Regulations• Simple, Aordable & Reusable• Residential, Multi-Family & Commercial Applications• Unique Free Standing Design• Keep Post Attached For Reuse On Next Level Or ProjectFeatured on osha.gov website!for more informationFind out more about Doleco USA and its DoNova PowerLash Textile Chains, visit www.doleco-usa.com.
AUGUST 2020 www.mcsmag.com30equipment solutionReel Trailersallowing optimal equipment utilizationEXCEEDING EXPECTATIONSSouthland Electric, Inc. is a San Diego-based commercial and industrial electrical contractor that serves the Southern California region. The woman-owned company does electrical work for entities like Cox Cable, San Diego city schools, San Diego Gas & Electric (SDGE), and many more. “We install, splice, and test SDGE’s fiber optic and copper communication cables between substations. Recently, we have been installing a fiber optic cable 1 foot above a 16-inch gas main,” says Dale Thompson, an outside plant supervisor for Southland Electric, Inc. Southland needed a few cable reel trailers to free up its Telsta, a bucket truck(s) with a reel carrier on the back, to do aerial work where needed. When conversations first started, Southland was looking at Felling’s FT-14 R cable reel trailer. Dale worked with Mark Rapp, Felling’s Utility & Telecom product manager, to ensure that they ordered the right trailer for the project. After reviewing the project’s needs, Dale decided that the FT-6 R would be sufficient for the company’s current needs. SOUTHLAND TAKES DELIVERYSouthland took delivery of its first FT-6 R cable reel in May; the trailer was equipped with hydraulic retriever/take-up, rim drive, with a self-contained hydraulic power pack. “I was thoroughly impressed with our new FT-6 R reel trailer. It’s a beautiful cable dolly. Hydraulics are very well done. Very sharp in appearance. Very easy to use,” says Dale. “On gas projects, we start the process with a 4,500-foot reel of fiber optic cable. The gas line is being installed in the middle of the street, so at the end of the day, the cable has to go back on the reel so we can lower it into the trench and then cover it with steel plates,” says Dale. “We are only trenching 150 to 200 feet a day, so we have to figure 8 the entire reel of cable so that we have a starting end of the cable to pull under any gas, telecom, cable, etc. encountered. Then, we use our new Felling FT-6R trailer to wind up the cable and put it back in the trench.” What is a figure 8? The process of “figure 8’ing” allows a contractor to park the trailer mid-span of the run and pull it in both directions. The cable has to be emptied from the reel and laid on the ground, laying it in a figure 8 pattern; it prevents it from being twisted as it is pulled in two directions. Not knowing how much material they will need or what they are going to run into, they figure 8 the entire reel. Once the material is pulled through the obstacle, they load the material back on the reel, and it then can be deployed by driving along the unobstructed trench. With the first FT-6 R in service, an additional one or two reel trailers were still needed; these would need to be a bit more customized for the project application. Dale had two more projects coming up that would need the capacity for 38-inch reel, (50 reels total), which would require the rim drive to be extended by another 2 inches. CLOSING THOUGHTCustomizing a trailer to a customer’s needs is Felling’s forte. Mark worked with Felling’s Engineering and Weld teams to execute the extension request. The hydraulic drive was extended to accommodate the turning of a 38-inch-diameter reel, allowing for the rim drive hydraulic retriever/take-up system’s Felling FT-6 R with hydraulic retriever/take-up rim drive.

AUGUST 2020 www.mcsmag.com34equipment solutionThe electrification trend that has been a topic of conversation for some time is now catching on in various vehicle segments, most notably in the automotive space. Following the recent advances in the auto industry’s speed of introduction of electric cars, construction equipment manufacturers, typically fast followers of the automotive industry, have continued to iterate and launch electrified machines with varying degrees of electrification technology. The focus is around potential environmental and productivity advantages. A recent report published by IDTechEx Research predicts that the majority of new construction vehicles will be electrically powered by 2029, less than 10 years from now.Electric scissor lifts have been in production for decades. Since that time there has been rapid adoption and growth in utilization of scissor lifts in a wide range of applications. Many new categories with different shape and size scissor lifts have been created to respond to unique end-user jobs. Throughout the decades, innovation has been relatively incremental, adding new height classes and few differentiating features. The market has focused on low-cost innovation and there have been shifts in customer preference accordingly.One of the most popular configurations features an electric drive system which offers fewer hydraulic hoses, therefore fewer leak points. In recent years, as talk about electrification has ramped up, and environmental regulations have become more stringent, advances in electrification have continued to move forward. As more manufacturers add varying levels of electric technology, be it DC (direct current) or AC (alternating current) drive motors, the improvement in duty cycles and reduction in potential leaks through fewer leak points has been notable.BENEFITS AND EVOLUTION Electric powered scissor lifts are more environmentally friendly than their engine powered counterparts and they are especially useful for working in enclosed spaces. The simplified nature of batteries compared to engines, especially as engine regulations have continued to evolve adding aftertreatment, Diesel Exhaust Fluid (DEF) and other technologies that have driven engine costs higher. The result has been and will continue to be increased demand for electric products since they reduce the number of service calls related to engines, aftertreatment and likely drive reduced fluid leaks on jobsites, a common type of scissor repair technicians is called upon to fix. Depending on the make and model selected, the upcoming ANSI 92.20 regulations have required specification changes on some models, more or less capacity in certain categories and clear distinctions for operation parameters in indoor vs outdoor use. The JLG ES Series, has been the industry benchmark for electric scissor lifts due to its highly efficient electric drive system and strong return on investment. The batteries in the ES Series deliver up to 200 percent more life per charge for improved performance on the job. They tend to last longer, “True” All-electric Machinereimagining the scissor lift for the next generation of jobsitesBy Rafael NunezINNOVATION ADVANCES
www.mcsmag.com AUGUST 202035allowing rental companies to extend the life of batteries, the single highest cost driver for scissor lift ownership. The expanded ES line features a wide range of models from 13-ft to 32-ft platform heights and was launched with new productivity and digital features that will make it the continued market leader in the scissor lift category for many years to come. EVOLVING TO ALL ELECTRICThough there is no shortage of battery powered scissors on the market today, the next generation of electrification is upon us. Some manufacturers are highlighting that they are “battery-powered” or “electric,” or in some cases “fully-electric” while still maintaining hydraulic cylinders for actuation. ALL-ELECTRIC SCISSORS APPLICATIONSThe newest all-electric scissor lift is manufactured with sustainable technology that drives a high value over the lifecycle of the machine. It is ideal for applications such as data centers, clean rooms, hotels, casinos, museums, big box stores, and in urban spaces where stringent environmental regulations related to noise and emissions must be met.As JLG continues to push the envelope in innovation around the entire ecosystem from our rental partners to jobsites. This new machine unlocks new possibilities and applications where these types of machines could not be used in the past due to leak opportunities. We look forward to partnering with users to help them maximize productivity and continue to help build and maintain the infrastructure in the world in more sustainable ways.CLOSING THOUGHTLooking towards the future, the JLG Davinci delivers an environmentally friendly innovation without unmatched machine performance. The AE1932 raises the bar and sets a new industry benchmark for productivity with minimal maintenance. And, the unit is the only scissor lift in the industry to recover energy when the platform is being lowered, contributing to a 70 percent decrease in power consumption and allowing for the use of a single lithium-ion battery.

AUGUST 2020 www.mcsmag.com36One of the biggest threats facing construction projects today is an invisible one that lurks just below the surface. The labyrinth of pipelines and utilities buried under modern cities pose a significant risk to projects. In 2018, workers reported more than 330,000 underground utilities strikes in the United States and more than 11,000 in Canada. That was an increase of about 13.5 percent since 2015, numbers show.On average, there is a utility strike somewhere in North America every 10 seconds, but it’s a problem that doesn’t have to exist, and there is a clear solution. In eliminating the threat, organizations can save money—not to mention headaches or even the potential for loss of human life.Data from The Civil Quarterly (TCQ), a new publication launched in July 2020 from Dodge Data & Analytics, revealed contractors in heavy construction are facing supply chain issues and other challenges in keeping their jobsites going amid COVID-19.But digging deeper, this brand-new data also revealed that 63 percent of the contractors contacted for the study are currently using or considering using utility detection tools. A staggering two-thirds of contractors shared a new prioritization on safety investments overall, to include utility detection. According to a somewhat dated Purdue University study, which remains the most commonly cited in the industry, companies can save $4.62 for every dollar spent on utility detection. Other estimates show potentially more significant cost savings, possibly reaching $18 for every dollar spent.Regardless, the savings can total billions of dollars every year. Shutting down a project because of a utility strike can easily cost companies $2,000 or more per hour, a significant impact on the bottom line of any company or project.OPTIONS TO DETECTMany utility strikes result from excavation mistakes. Others are made because crews didn’t report they were digging or because of errors in reporting underground utilities’ existence.There are two primary technologies to help crews detect underground utilities: electromagnetic locators and ground-penetrating radar.These technologies work differently, so one is not necessarily superior. Electromagnetic locators effectively locate metal or metallicized utilities, while ground-penetrating radar can help find other buried items, such as plastic pipes.Remaining vigilant while excavating a jobsite remains of paramount importance as neither tool is guaranteed to find everything, particularly items found buried deeper than 15 feet. But, working in tandem, these tools capture the overwhelming majority of buried utilities.A GROWING FIELDThe field of super subsurface utility engineering continues to evolve as it matures. It is poised for significant growth as projects become increasingly complex and budgets tighten, making mistakes even more costly.There are three emerging sections within the utility detection arena: utility companies, specialized detection companies, and construction companies that take it on themselves. Now there are new—and easier-to-use tools—that are simplifying utility detection across the industry.Today, 40 percent of contractors use utility detection tools, while another 23 percent use or consider the technology, according to TCQ.BE WARY OF FREEThere are free options for detecting underground utilities. While these are tempting, it’s important to remember the old adage, “you get what you pay for.”An estimated 65 percent of the buried utility lines in North America are deemed private, so many buried utilities aren’t fully verified. Considering utility owners aren’t necessarily required to participate in nonprofit programs—such as the Common Ground Alliance’s 811 program—that help companies locate underground utilities before they dig, and there is a potential recipe for disaster.While asset owners theoretically know where their underground utilities are buried, free services often inaccurately mark the locations. It’s one thing for a homeowner to receive wrong markings, it’s another for bad markings on a significant What Lurks Belowthe maturing of utility detection in heavy construction NEW DODGE REPORTBy Simon Pedleymanagement solution
www.mcsmag.com AUGUST 202037commercial project where millions of dollars—and even dozens of lives—are at stake.IT’S ABOUT SAVING TIMEMapping utilities used to be a time-consuming affair, as crews would have to download data from a detecting device, upload it to another system, and then cross-reference the data to make sure where they planned to dig is safe.It’s no problem for teams with days to spare, but today, it’s about getting the information in real time to keep crews active and working safely and efficiently.Modern solutions have changed the approach, making it easier for companies of all sizes to understand what lies beneath their project and keep everyone on their team in the loop. They can also be deployed by small teams or single team members, making these solutions well-suited for the new social distancing requirements amid the COVID-19 pandemic. Due to the easy-to-use and advanced implementation of these solutions, they can also be deployed without hiring additional team members or undergoing extensive training.But, detecting utilities is just the first step in the process.Tools employ smart algorithms to create digital utility maps in minutes, displaying detected results while users are still in the field, allowing project managers to make real-time decisions. Users can export the data for use with post-processing software and machines, or they can overlay with additional data for a more robust picture of an environment.CLOSING THOUGHTTechnology is a powerful enabler of a better way to approach problems facing organizations today. From advanced, multi-dimensional drawings of project sites to realistic 3D renderings of new projects months or even years before completion, technology has revolutionized the construction industry, and utility detection is no exception.There is no reason to strike an underground utility because the crew did not take the time to try and locate it. Today’s available solutions streamline processes and make the jobsite safer and allow project managers and their teams to avoid inadvertent strikes of buried pipelines and utilities.Simply using this technology can save thousands—potentially millions—in fees, repairs and lost time.

AUGUST 2020 www.mcsmag.com38management solutionThat quote from Ben Franklin applies to many things in business and in life. It especially applies to handling problems and complaints. What’s the best way to handle problems and complaints? There are many answers to that question. Essentially, with the utmost professionalism; with cool, calm collectedness; with tact and diplomacy. Here’s the BEST answer: Avoid them in the first place! I’m a firm believer in the best practice of Proactive Complaint and Problem Prevention.As a contractor, there are numerous actions to take that will help you to avoid problems and complaints. Review and implement these best practices of progressive contractors to reduce problems and complaints.A FEW MORE TIPS• “Oh, come on Sam. We don’t need a meeting. We’ve worked with you for years!” Go over the punch list with your subs on every job—even if you have worked for years with the sub and you know they do a great job. Let the sub know that the prework meeting to go over the punch list is not optional. It is mandatory.• Document every complaint and talk about how they could have been avoided.• Hold weekly meetings to discuss “Hits,” “Runs,” and “Misses.”• Have your accounting team check and double check every entry into your accounting system.• On a regular basis, ask your project manager, accountant, office manager, etc. this question: “Is there anything I should know about?” If you don’t ask, they may not tell you.• Demand workers to start working at start time, and not stand around chatting and drinking coffee for half an hour before they get started. • Keep your tools and equipment in tip top shape. Note when parts need to be replaced and equipment needs maintenance service. No one likes downtime.• Communication and accountability from each member of your team is imperative to accomplish even the simplest task. • Hold weekly meetings with your superintendent, project managers, and foremen to talk about the week before; discuss any problems that occurred and how you could have avoided potential problems.• Make sure your estimator applies their expertise, skills, and knowledge to account for any uncertainties that might arise during a construction project. • Make sure every department and every employee will make every effort to provide great service to each other. If they don’t, how can you develop a reputation for being a top-notch contractor?• Check and cross-check the punch list with pertinent documents.• Keep your client informed when a problem occurs. Honesty is the best policy. • Instruct every employee to display a sense of urgency to respond to any request. • Never make a promise you can’t keep.• Ask complete questions, paraphrase to reconfirm what customers want so you don’t make a mistake. • If you are not sure of something, just ask!3Ps to the Rescuean ounce of prevention is worth a pound of cureBy Christine CorelliPROACTIVE | PROBLEM | PREVENTION
www.mcsmag.com AUGUST 202039WHEN YOU CAN’T HELP What do you say when there’s a complaint or problem? Use words and phrases that display professionalism and empathy. This can be challenging—especially when you have to deal with someone who thinks they know better than you! The following are examples of phrases known by customer service professionals as “verbal cushions.” These should help you face these difficult situations.• “John, I would like to be able to tell you I can do this for you. Unfortunately, it’s not feasible with this project.” Then, explain why.• “Based on my experience, this could have been avoided if…”• “I don’t blame you for being upset, Mr. Smith. I would feel the same if I were you.”• “I feel really bad about this, John. It couldn’t be helped.” • “I’m understand the seriousness of being behind. The I appreciate your patience. The weather has been against us.”• “I apologize if there’s been a misunderstanding. Mr. Smith, I’ll talk with the project manager immediately and get back to you as soon as I obtain answers for you.”• “I am sorry that you think you were overcharged, Joe. Let’s walk through the invoice together. If there are any errors, we will make corrections immediately.”• “I understand your position, John. If I could do more for you, I would.”Take the leadership role. Work with your team to create your own list. Print it out so everyone has them and consistently update them.CLOSING THOUGHTA final word on problems and complaints: Never carry an encounter with a difficult client or situation over to your next job, or take it out on your team. Understand that times are tough for everyone these days. Accept that in the construction business, and in every business, complaints and problems come with the territory. What is most important is that you have systems and procedures to prevent them from occurring. Proactive complaint and problem prevention is a smart practice. about the authorChristine Corelli is a conference speaker, workshop facilitator, and business columnist.

AUGUST 2020 www.mcsmag.com42software solutionDigital Transformationmore attainable than ever beforeBy AJ WatersIT HAS ALREADY BEGUNEven with the advancements we have made in personal technology, the mention of a digital transformation continues to set off alarms for many companies, especially in construction. The continually evolving nature of technology means digital transformations are more akin to ongoing cultural shifts than a single finite project.The move to digitize the way we work has become a fundamental part of our daily lives that can no longer be dismissed as an idea reserved for corporate giants with seemingly unlimited resources. Implementations are no longer as complicated or labor intensive as they once were, thanks to the leaps forward in consumer technology, and construction companies of all sizes are beginning to reap benefits. HIDDEN IN PLAIN VIEWFrom the advent of the first computer, digital transformations were being consumed at different levels based on available budget and savvy. Remember how BlackBerry took corporations by storm? However, that all began to change with the announcement of the first-generation iPhone. The race to create consumer level advanced technology was on, and now almost everyone carries around the most advanced mobile devices in their pocket.With the explosion of mobile technology came the need for a cloud backbone to support it. Today, the cloud is everywhere, and rightfully so, with our ever-increasing use of data catapulting cloud businesses to exponential consumer growth. But there is an often-overlooked component that arguably has been more vital than each of these. User experience (UX) and user interface took center stage as developers went to work accommodating these new screens and speeds. No digital transformation is ever successful without being intuitive to the end user, and this move to consumer mobility was no different. As evidenced by the rapid UX professional growth over the last decade, rising from 100,000 in 2010 to over a million in 2020, technology developers scrambled to make platforms easier to use, and easier to saturate into the market. ACCELERATING CHANGEThis rapid consumerization of digital transformations has business benefits, too. The very first versions of estimating software required a dedicated machine loaded with a set of twelve floppy disks, installed in a particular order. However, thanks to the enterprise advancements in cloud computing, today it is as simple as typing a URL into a web browser that’s already installed on your PC. The same is true with mobile technology. Most of your on-site personnel are already carrying a smart phone and the download of a simple app transforms them into project management tools. Not only does this significantly reduce hardware costs, but it also reduces the time users take to become comfortable with navigating the technology. Any training that might be needed can be delivered in-app, allowing the user to learn while on the job. The foundation of all of this, though, is the 30 years of user interface improvements. Power buttons, volume sliders, swipe left to advance. The list is endless. It is the synergy found by combining of each of these factors, intuitive, mobile technologies deployed with SaaS cloud computing, that brings the real win to organizations—visibly reducing the time, cost, and resources required for implementation of a digital transformation. NEXT STOP: TRANSFORMATION With all of this in mind, there are three “quick wins” that could kickoff constructions’ path to digital transformation. First, the way project drawings are managed has struggled to evolve over the last 30 years. What was AUGUST 202042
www.mcsmag.com AUGUST 202043acceptable then is no longer capable of addressing the large data demands of a rapidly changing, modern construction site. While there has no doubt been some improvement, version control is still a struggle for most projects. Second, yet another paper process, is timecard and progress management. This goes beyond payroll as it loops in safety, quality and often more. Without a level of digitalization, this remains a labor-intensive, manual process. Finally, without digital transformation, the future value of the data being collected remains hidden. History and past costs might be stored somewhere, but without proper access and reference points, you are unable to take actionable steps to improve plans for the next time, or to reduce rework. It is no wonder the construction industry continues to be plagued with projects that are behind schedule and over budget. WHERE TO BEGIN Even with everything that has been discussed, a digital transformation may still seem daunting. While it is often difficult to understand where to begin, here are three questions that can help set you up on a road toward success:1. Are we truly prepared for this? 2. Do we know what is important to us? 3. Do we have the right people in place? CLOSING THOUGHTRemember, this is an ever-changing journey, not just a one-time, finite project. Now, more than ever, digital transformation success is waiting for companies of all shapes and sizes in the construction industry.

AUGUST 2020 www.mcsmag.com44legal solutionAlthough deemed an “essential business” by many states, the construction industry is evolving in conjunction with a pandemic and increased market volatility leaving construction companies wondering what is next or where business will take them. Now is the time for those in the construction industry to abandon a specialization in strictly private projects or strictly public projects. The shift from private projects to public works can be intimidating; nevertheless, most public works projects considered essential during the pandemic will continue whereas private projects are at a greater risk to shut down.Damage to the construction industry during the first half of 2020 was unmistakable. Overall, the industry plunged 22 percent below the first half of 2019, yet public bidding opportunities remain available in abundance. In early June, Dodge Data and Analytics found that there were more than 500 public bidding opportunities in California, Texas, Florida, Illinois, Ohio, Pennsylvania, and New York alone. Diversifying your ability to bid on both public and private projects ensures that your business is open to every opportunity. This article examines the differences between public and private projects to assist those considering expanding their reach across the public-private lines. The article will also examine certain relevant preferences that may assist in obtaining public projects. BIDDING PROCESS & PROTESTSPrivate bidding is a quality-driven procurement while public bidding is far more competitive, often driven by cost dictated by governments with budget deficits. In a private project, the owner, on the advice of its design professionals, selects who it wants to work with based on factors that which the owner deems as a priority. A private project owner also has the prerogative to bid-shop and negotiate with its contractor.Public bidding is regulated to ensure fair competition. Most states have enacted statutes on competitive bidding. Colorado calls on government employees to adhere to the “highest standards of ethical behavior” relative to procurement. Likewise, West Virginia implements personal liability for those state employees who violate procurement procedures.FINANCIAL IMPLICATIONSProfit margins are generally higher on private projects. Because public projects generally award to the lowest bidder, the private-project bidder can include a higher profit margin into its bids without the risk of price disqualification. On the other hand, there is more confidence in getting paid when procuring a public contract. The government pays, just not always timely. Bonding requirements add cost to a project. The Miller Act, applicable to federal public jobs, requires contractors to post several different bonds. Before a contract of $100,000.00 or more is awarded, a construction company must furnish a performance bond and a payment bond. The bonds must provide coverage for taxes. CONTRACT NEGOTIATIONSUnder principles of contract law, private contracts are negotiable. Public contracts are often non-negotiable. If the terms of a public contract are unsettling, nothing typically can be done about it. For example, in most instances, states have a boilerplate contract that must be signed when performing work on highway projects. Regardless, it is important to have an attorney review a public contract to make sure that the terms can be adhered to and that the contract is as fair as possible.

www.mcsmag.com AUGUST 202045initiated, but a realistic understanding of the outcome is important. PREFERENTIAL DESIGNATIONSTo bring diversity and inclusion to the construction industry, states and the federal government offer advantageous bidding consideration to those businesses with certain designations and certifications. Obtaining designations and certifications avails a construction company to greater opportunities, including preference in bid selection. Some companies, simply because of ownership and demographic, will not qualify for certain designations, but doing business with companies that have designations will help those unqualified businesses “score” better when applying for grants and contracts.In 1983, Congress enacted the Disadvantaged Business Enterprise (DBE) Program. DBE requires the U.S. Department of Transportation to award at least 10 percent of federal funds designated for transit projects to DBE qualified businesses. To be certified as a DBE, a business must have at least 51 percent ownership and control by a woman, minority, disabled person, or veteran who physically resides in the United States and can prove economic disadvantages.The Minority Business Enterprise (MBE) certification also requires that a business be owned and controlled at least 51 percent by a member of an identified minority group who is a U.S. citizen. MBE is similar to the DBE, but a business does not have to be certified by the government to receive the designation. The National Minority Supplier Development Council, for example, is one of the largest MBE certifiers in the United States. The programs differ in that MBE requires citizenship while DBE requires residency. The Women-Owned Small Business (WOSB) program was established by the Small Business Administration. The program calls for the federal government and its agencies to award at least 5 percent of all industry dollars to businesses designated as WOSB. To be eligible for the WOSB, a business must be a small business, but at least 51 percent must be owned and controlled by a woman who is U.S. citizen and manages the day-to-day operations of the business while possessing long-term decision making power. CLOSING THOUGHTAs things change in an unprecedented world, construction businesses may need to make changes as well to maintain revenue stream. Diversifying the abilities of your team and your projects can open doors in both the private and public sector. Although crossing the private-public lines may appear intimidating, your business will have an ability to thrive even in difficult times. Now may be the time to at least transition of portion of your business to public projects. about the authorsDanielle Waltz is a commercial and construction litigator and government relations specialist in Jackson Kelly PLLC’s Charleston, West Virginia, office, where she is a member.

AUGUST 2020 www.mcsmag.com46technology solutionThere’s a difference between managing projects and running a construction company—at least that’s what most people think. Many companies will conduct internal capital projects to create a new product or improve efficiencies, but it’s not their main source of income. For construction companies, delivering projects is how they directly serve their customers, and essentially, how they make money. More specifically, the projects they deliver directly affect their bottom line. The fact of the matter is productivity in the construction industry has remained stagnant and even declined. By understanding the seven challenges of the construction industry, it will be easier to take the necessary steps to be more productive, profitable, and ultimately successful. ACCEPTANCE OF THE STATUS QUOConstruction companies are often submitting RFPs and RFIs for ERPs and business systems with requirements that are limited around project accounting. This assumes that any kind of financial and operational project management is done in third-party applications or spreadsheets, but not in the main business application. It’s time these companies demand more from the business solutions they adopt. Sticking to the status quo due to habit means technology providers will continue to sell glorified accounting software, which means construction companies will continue to manage their business processes through spreadsheets and disparate point solutions. FAILING TO IDENTIFY AS A PROJECT BUSINESSIt’s impossible to identify as something you don’t know exists. The term Project Business has been around for a while, but it remains relatively unknown to project-based companies (e.g., construction) that should be recognizing themselves as such. Failing to identify as a Project Business causes them to focus on the wrong aspect of their business. Oftentimes, project-based companies will focus on the 5 percent of their business that makes them unique from other companies when really their focus should be on the core part of their business projects. To see the most productivity gains, construction companies need to take care of managing projects. After all, it’s 80 to 90 percent of what they do. OPTIMIZATION OF PROJECT MANAGEMENT SILOS HAS MAXED OUTThere’s been a lot of effort in trying to squeeze as much efficiency out of silos, or the different aspects of project management that are managed in spreadsheets and point solutions that make up the fragmented data landscape. As a result, productivity in construction continues to decline. Instead of putting time and effort optimizing these individual silos, construction companies need to focus on optimizing the net total of all the silos and think of the enterprise as a whole and implement a single, integrated solution that manages all their Project Business processes. Moving Forwardseven challenges of the construction industry KNOW TO GROWBy Daniel Bévort
www.mcsmag.com AUGUST 202047 INADEQUATE COMMUNICATION AMONG KEY STAKEHOLDERS OR LACK OF STAKEHOLDER COLLABORATIONOftentimes, key stakeholders have different versions of project information and operate within their own silos, making it difficult for them to collaborate and have a shared opinion of where a project is at. Why? They are operating in different tools and using different information. It’s impossible to implement a communication strategy or Project Business governance program in such a disjointed arrangement. To do a better job of communicating, everyone needs to be on the same page. Giving key stakeholders the tools and having them work from one source of truth enables better outcomes for your projects. LACK OF GOVERNANCE, LACK OF STANDARDIZED SYSTEM OF ORGANIZING THE DATAConstruction companies operate in a very fragmented application landscape, deploying multiple tools and solutions to manage their business. This results in the lack of Project Business governance—a standardized approach to the management of processes and data in project-based companies. Not only is it difficult to control the process, it’s also difficult to trust the output. In addition, instead of having a governed set of processes, you’re relying on individuals. In the long run, it makes it difficult for construction companies to have scalable business processes. LACK OF AUTOMATIONConstruction workloads or processes are usually limited within a silo. There are workloads that happen in the planning silo, workloads in a specific spreadsheet, or workloads that happen on the procurement side. If something happens in the planning silo, that event needs to translate into a spreadsheet or communicated to the procurement department. Lack of automation means someone needs to intervene and make that transition from one silo to the next. And oftentimes, that doesn’t happen. As a result, project controls and workloads are neglected, and it prevents the flow of information across the enterprise. Construction companies operate in a very fluid, high-risk environment that demands organizational agility. LACK OF REAL-TIME INSIGHTThe number one complaint from C-level executives is they don’t actually know what’s going on with their projects until they are done. Why? They don’t have that information available. If they want that information, they must dedicate people to finding that specific information and presenting it in the right format. This means executives end up making important business decisions based on either no data or unreliable, outdated data. In some cases, they don’t make any decisions at all. In addition, lack of real-time insight means there’s no way to have early detection of issues. If you’re able to identify a problem while it’s small and manageable, then you can mitigate and prevent it from becoming worse.CLOSING THOUGHTIf you’ve done the same thing for decades, making a big change can be difficult. But when the bread and butter of your company depends on completing projects on time and within budget, ensuring your Project Business processes are as efficient as they can be is essential. Recognizing the seven challenges of the construction industry not only helps you identify what solutions are possible but positions the company for growth and success. about the authorDaniel Bévort is founder and CEO of ADEACA.

AUGUST 2020 www.mcsmag.com48technology solutionThe team at Beecher Walker faced more than its share of challenges in the design and construction of The Hale Centre Theatre in Sandy, Utah. Weather, timing, and establishing a foundation strong enough to support the structure in watery soil were among the most pressing riddles facing the architects and construction management teams, and the room for error was as thin as a thimble.THE CAREER PROJECTOne other concern confronting architects was solving acoustical issues. The theater, with a seating capacity for 1,360 patrons spread out over two theaters, sits below the flight path for planes heading into and out of a nearby airport. Cars, trucks, and other vehicles rumble past the theater on an adjacent highway. Nothing can destroy the mood of “Mary Poppins”—one of the Centre’s shows scheduled for this year—like the sound of the horn of a 16-wheeler rumbling past, the wail of sirens from an emergency vehicle, or thunder from an overhead airliner arriving for a landing.With those underlying concerns in mind, every acoustical decision had to be on point. “This,” architect Lyle Beecher says, “is a career project.” His team selected every detail carefully, particularly as they related to acoustics. They constructed 18-inch thick concrete walls and installed mechanical equipment outside walls to minimize noise infiltration. They also selected 20 acoustical smoke vents manufactured by The BILCO Company. This year, BILCO introduced its new ACDSV smoke vent, which provides the highest level of protection against exterior noise intrusion. Smoke vents are also life safety products that also help protect the building structure.“Air traffic was a big consideration for us,” Beecher says. “The smoke vents are the only thing stopping the noise coming in from the loading level on the outside. BILCO has a good reputation for its products and the sound issue was pretty intense.”Acoustical performance is one of the major concerns for architects in the construction of theaters, stages, and other performance centers. The key indicators in equipment are ratings that fall into two categories: sound transmission class and outdoor-indoor transmission class. Depending upon the structure being built, the difference in ratings is essential for architects to understand. TERMINOLOGY IN ACOUSTICSWhile there are a lot of considerations in determining acoustic quality, building materials are largely measured by STC and OITC ratings. Architects and material specialists must not only select the materials with the proper rating for each project, but also must determine which measurement is more important for that particular project.STC measures the extent to which sound is prevented from being transferred from one area to another. The higher the STC value, the less that sound can be transferred through a building product. STC is typically used to measure sound transmission loss over a frequency range from 125 to 4000 hertz and is most applicable for interior areas that experience mid to high-frequency noises, such as conversation, television, telephones, and office equipment. A product with a high STC value, ranging from 50-60, indicates that loud speech is barely heard (assuming a typical background sound level for an office, approximately 45dBA) through the product. A low STC rating, 20-25, indicates that loud speech would be audible through the product. OITC rates the transmission loss of sound through a material when outdoor Sound Decisionsdifferent ratings help architects weigh acoustical choices By Thomas RennerBEST PRACTICESAcoustical performance is a major concern for architects in the construction of theaters, auditoriums, and performance centers.

www.mcsmag.com AUGUST 202049sources need to be considered. Like the STC rating, OITC measures sound intensity loss in decibels. The OITC rating was developed in 1990 and is typically used to measure sound transmission loss over a frequency range from 80 to 4000 hertz. It is most applicable for measuring the prevention of low-frequency exterior sounds such as automotive traffic, construction, and low-flying airplanes through exterior building surfaces.“OITC is the preferred rating when addressing sound insulation from exterior noise—especially when transportation noise sources are impacting a building facade with significant low-frequency (bass) sound,” says Harold Merck, principal and acoustician for Merck & Hill Consultants of Atlanta. “While STC ratings may be fine for typical interior noise sources such as voices, STC doesn’t adequately address the extended low-frequency noise contribution of aircraft, traffic, or even large roof-top equipment. This also applies to large roof-top equipment noise sources as well. The OITC better addresses low-frequency noise impacts and is the more applicable sound rating for roof mounted automatic smoke vents.”THE RIGHT CHOICEAccording to Albert Maniscalco, a partner with Cerami and Associates in New York, the STC and OITC requirements vary according to each project. In school construction, for instance, the STC ratings are used for acoustically rated doors and windows within the school such as for music practice rooms. However, the school may also require acoustically rated exterior windows or other façade elements to properly mitigate exterior noise intrusion. In this instance, the OITC rating would be used. Maniscalco also explained that noise control works both ways. He cited the example where elements of a building exterior can be designed to keep the sound within the building such as a concert or sports venue that is near residences. “Noise goes both ways,” Maniscalco says. “Sound can come in and go out. How that façade performs with noise coming in or going out is important to know.”Building materials include STC and OITC ratings, but architects have to account for various sources of noise and make the appropriate choices. “Windows might have an excellent STC rating, but without a high OITC rating, low-frequency sounds can be intrusive,” Merck says. “Windows with a high STC rating typically have the same OITC rating as windows with a lesser STC rating, which can be a bit misleading. Ratings that include the OITC are more useful to assess how well a window will isolate environmental noise.”CONTROLLING NOISEThe new smoke vents from BILCO come with an STC rating of 50 and an OITC rating of 46, providing the highest level of protection against exterior noise intrusion. In addition, the product has also received an ISO-140-18 sound rating when tested against rainfall sound. The rating measures the impact of sound insulation on building materials—such as roofs, skylights, and roof/ceiling systems—incur when exposed to artificial rainfall.Automatic smoke vents are life safety products that are generally used in large one-story buildings per National Fire Protection Association (NFPA) standards. In the event of a fire, the vents exhaust smoke, heat, and burning gases from the building to improve visibility and to protect the building structure. This provides safe egress for building occupants and allows firefighters to enter the building and contain the fire. The new design of the BILCO acoustical smoke vent features mineral wool insulation and high-density sound mat material within the unit’s covers and curb to better inhibit sound transmission. Structural improvements include the use of heavier gauge steel for the curb and cover liner, a new cover gasketing system, gas-spring lift assistance, and a center-mounted gas traction spring to ensure reliable and controlled smoke vent operation. CLOSING THOUGHTAt the Hale Centre Theatre, the smoke vents provided a critical safety component while also protecting against noise infiltration. The new theater provides more than twice the seating capacity of its former facility, and gives patrons a first-class experience—without having to hear the nuisance of exterior noise. “This theater, by all standards, is a world-class venue,” says Mark Dietlein, the president, CEO and executive director of the theater. about the authorThomas Renner writes on building, construction, manufacturing, and other topics for U.S.-based trade publications.20 acoustical smoke vents were used in the construction of the Hale Centre Theatre in Utah to help limit noise intrusion from the exterior.

AUGUST 2020 www.mcsmag.com52safety solutionConstruction managers, general contractors, and building owners are certainly familiar with safety netting systems and the reasons to install them, which include protecting workers and debris from falling from structures, as well as façade and ceiling containment. They also believe these passive systems create and maintain a safe work environment.However, when it comes to specifying the appropriate solution for a construction project, many see netting systems as, well, pretty much all the same. In reality, this could not be further from the truth, given the broad variability in the quality and construction of nets, suitability for the stated safety purpose, quality of testing, and other factors that impact the ability to meet a broad range of national and state fall protection and debris control standards. KNOW THE EXPERTSWhile this list is extensive, it only serves to underscore the fact that netting system selection should squarely rest in the domain of experts and engineers, and not viewed as a mere commodity item. As such, contractors and building owners often rely on third parties with a wealth of netting-specific knowledge and expertise when devising safety plans or designing and installing rented or purchased nets and systems.“You can’t just put a netting system together that you feel is going to work, only to realize at the end of the day it was not sufficient for the purpose,” says Harry Weidmyer of Construction Safety Service and Solutions. “You are taking something that is a vital part of safety on a project and so you can’t take shortcuts and put up netting that seems easier, or maybe requires a little less labor.”There are other reasons that well manufactured and designed netting system also makes good business sense beyond the safety aspect. It can also reduce insurance costs, improve safety ratings, speed Netting Systemsvariability in quality/design illustrates the critical role of third-party experts FALL PROTECTION/DEBRIS CONTROL
www.mcsmag.com AUGUST 202053productivity, boost worker morale, and create a positive public image.NO SHORTCUTSAs vice president of risk management at a major construction firm in New York for 20 years and now president of his own company, Weidmyer has witnessed the variability in netting system installation first-hand.Given his company’s focus on risk assessment and loss control, Weidmyer has had the opportunity to work with contractors in New York, Connecticut, New Jersey, and Florida to review their insurances and to monitor their safety program and protocols. Outside of New York City, which is known for the some of the most stringent netting system codes in the country, Weidmyer says, “I’ve seen netting system installed by contractors that I feel slice it thin in terms of protection. For example, they install a debris net that serves only the minor purpose of catching light debris, but if somebody fell into it, it is not going to support them.”Weidmyer says that in New York City, the nets specified and installed are often expected to serve double duty of catching heavy debris as well as providing personnel fall protection. The codes even require paperwork that verifies the integrity of the manufacture of the net itself.ACCORDING TO OSHAOSHA Guidelines Subpart M and Article 19 of the NYC Building Code require specific safety systems on a construction site. To meet the guidelines, contractors must submit a site safety plan to the city. For high rise buildings 15 stories or more, netting is typically mandated in the safety plans from the 6th floor up. Nets are the primary passive fall arrest system option on the market and usually the most cost effective. They provide not only fall protection and the separation of trades, but also protection of workers and the public, in addition to other property below from falling debris. In addition, netting can be used for other purposes including as a scaffold and barrier netting, for façade containment, and to protect the public from falling debris from deteriorating buildings until permanent repairs can be undertaken. For the past 35 years, Weidmyer says he has relied on Pucuda – Leading Edge for the netting system designs in his safety proposals. Pucuda – Leading Edge designs the system and can submits the relevant paperwork and follows through until it is authorized by the Department of Buildings, if needed. Pucuda – Leading Edge is one of the few netting system manufacturers that produces nets in the United States and that has a history of innovation in product design. The company was founded 27 years ago by hands-on netting expert John Rexroad, president, founder, and CEO of the company. Weidmyer says the company is basically a one-stop-shop and he also turns to them for the nets as well, all of which conform to all ANSI, OSHA, Army Corps of Engineers, and ASTM standards. “John is a phenomenal net system designer and so is his team,” says Weidmyer. “I have recommended him to quite a few contractors in New York City because I know his systems are designed properly and there is no second thought or concern about them working properly.”NETTING AT CAPE CANAVERAL Pucuda is also involved in a unique project at the Kennedy Space Center at the Air Force station at Cape Canaveral, supplying netting systems for a structural steel project to construct a launch tower and a lightning strike tower. “On a portion of this particular project, we are building two towers and the primary function of the netting is to catch debris,” explains Alan Bukis of S&R Enterprises, the on-site project manager for the structural steel construction company. “So, if somebody is working up on level 400 and accidentally drops something, the debris netting will catch it before it goes to the ground and potentially hurts somebody.”In addition, the nets are technically rated for fall protection even though it is not the intended use. In addition to the netting, workers are expected to tie off using a fully body harness whenever they are 6 feet above the floor.
AUGUST 2020 www.mcsmag.com54safety solutionThese towers represent protection for the first new build of a Launch Pad in several decades. Therefore, it was important for S&R to interview several netting manufactures.“Overall, [Pucuda – Leading Edge] had the best presentation as far as we were concerned,” says Bukis. “John Rexroad definitely knows the netting industry inside and out, and it was very evident in our initial discussions.”One important aspect of the presentation was a review of samples of the netting, brought in by two of the three companies. “By appearance alone, you could see there was a higher quality netting with Pucuda – Leading Edge,” says Bukis. “The other company brought a sample and it was a considerable difference.” QUALITY MATTERSQuality in the manufacturing and materials of netting is a major factor in the selection process. Many nets supplied by U.S. based companies are imported from China or India where the manufacturing process is driven by supplying an inexpensive product in mass quantities.Even nets that appear adequate may have quality issues lurking under the surface that are not easily identifiable by the untrained eye. One example is a deterioration condition caused when an overseas supplier manufactures a net with a linked polymer that begins to deteriorate almost immediately. The condition is referred to as “wooly bear” syndrome, due to its appearance. This can dramatically affect the longevity and safety of the products.Although in the construction industry nets are often rented for a project, S&R Enterprises decided to purchase the nets from Pucuda in anticipation of additional future projects. For this reason, it was even more important that the net and system were manufactured with the highest quality materials and with longevity in mind.NETTING MEETS CHALLENGEBukis says there were installation challenges to overcome as well., as one of the towers was a sloping triangle that progressively narrowed as it went up.“When our team was installing the nets, they had a ton of questions about installing the netting correctly,” says Bukis. “So, we asked John to come to the site.”“He is not afraid to come out and go up in a structure and actually look at the installation,” adds Bukis, noting that this was also during the COVID-19 pandemic. “Just him being here and knowing that he’s the expert and him confirming that the installation was correct alleviated all their concerns. So, it was definitely beneficial that he was willing to come out and do that.”With netting systems, the most well-designed and manufactured systems are those that go unnoticed and can be taken for granted. It is only when someone, or something, falls and causes damage or injury to people or property, and it makes the evening news that netting systems take center stage.CLOSING THOUGHTWith so much at stake, contractors and building owners would be well served to seek out expert advice from netting system experts to avoid installing defective products that fall below the safety standards.“It all comes down to safety,” explains Bukis. “If something or someone happens to fall, you are going to want the best nets available. I feel much more comfortable with a higher quality product, because the goal is, we don’t ever want any of our people hurt.” for more informationFor more information about netting and Pucuda – Leading Edge, visit netting.com.

AUGUST 2020 www.mcsmag.com56maintenance solutionConcrete has been used as a strong, durable building material for thousands of years, dating back to many ancient concrete structures that are still standing to this day. Yet, it has one fundamental enemy it can’t escape—water. As an uptick in humidity and rainstorms wash across many regions of the country throughout the summer months, water infiltration can lead to issues such as below-grade reinforcement corrosion, surface scaling, aggregate expansion, mold growth, and more.In order to provide sufficient workability for proper placement, compaction, mixing, and transportation to the jobsite, most plant-batched concrete will contain excess water required to hydrate or chemically react with the cement. As concrete hardens, this excess water evaporates from the concrete and creates a network of fine capillaries and internal pores—essentially forming a “dense sponge” that allows water to transport through the surface, causing damage as a result.Here are a few of the most innovative reactive technologies that concrete contractors can use to combat water-related damage and ensure optimal concrete protection: CRYSTALLINE WATERPROOFINGCrystalline waterproofing materials can be applied as a slurry coating to the surface of an existing concrete structure, such as a foundation wall or floor slab, as well as broadcast onto fresh horizontal concrete and troweled into the surface. An alternative approach involves adding the admixture directly into the concrete at the batch plant. In all cases, the waterproofing function includes both complex chemical and physical mechanisms that take place within the concrete surface.As concrete hardens, the reaction between water and cement generates chemical by-products, which reside in the capillaries and pores of the concrete. When crystalline waterproofing materials are applied, the by-products of cement hydration and the crystalline chemicals produce a chemical reaction with very dense, non-soluble crystal formations. This crystalline formation will only occur where moisture is present, forming in the pores, capillary tracts, and shrinkage cracks of the concrete—the same routes susceptible to water ingress. Chemical diffusion can carry these crystalline materials deep into the concrete, plugging the voids in concrete and becoming an integral, permanent part of the structure.In lieu of penetrating from the surface as seen with a coating application, adding crystalline waterproofing chemicals to the concrete at the batch plant ensures that the crystalline formation occurs uniformly throughout the slab or structure. In addition, by adding crystalline chemicals directly to the concrete mix at the time of batching, the same crystal growth and Concrete’s Enemy: Waterways to ensure optimal concrete protectionBEST PRACTICESBy Jennifer Crisman
www.mcsmag.com AUGUST 202057waterproofing functions take place in a quicker, more cost-effective manner because labor associated with a surface treatment application is eliminated. Procedural sequence for addition will vary according to the type of batch, plant operation, and equipment. For most mixtures, the dosage rate of integral crystalline waterproofing admixture is 1-2 percent, based on the amount of cementitious material in the mix. SILANE & SILOXANE WATER REPELLENTSThe use of a waterproofing coating can be undesirable in some cases due to aesthetics or the desire for a simpler application process. Certain concrete applications do not need to be fully waterproofed, but instead can function properly with a water repellent treatment, such as silane and siloxane.Derived from the silicone molecule, silane and siloxane create an envelope of protection that can extend the life of substrates even in difficult environments. Both are UV stable, reduce efflorescence and freeze-thaw damage, are highly wear-resistant, and permit the substrate to breathe—in turn allowing interior moisture vapor to escape. Water repellent sealers can be used to impart water repellency to a variety of porous substrates, including poured-in-place or pre-cast concrete.Silane and siloxane sealers reveal little to no change in the appearance of the substrates to which they are applied. There is no gloss, color change or hiding of the substrate underneath. This is important when water protection is required for architectural finishes where a waterproofing coating would hide the decorative feature.While silanes and siloxanes provide excellent water repellency to surfaces, each has its own performance differences.Silane-Based Water Repellents. Corrosion and scaling due to exposure to salt spray and chemical deicing products is a primary cause of concrete deterioration. Silane-based sealers provide an extremely effective solution to prevent deterioration from water and salt. Silanes penetrate deep because of their extremely small molecular size and ability to chemically bond with silica to form a permanent attachment to the water-repellent molecule. This creates a deep hydrophobic layer that prevents water and waterborne contaminants from entering the substrate and causing premature deterioration, while simultaneously leaving the surface with a completely invisible finish and providing a chemical “screen” that prevents chloride ions from reaching embedded steel in concrete.Once applied, silane water repellents penetrate into the substrate and react chemically with calcium hydroxide to form a hydrophobic, water-repellent resin within the pores and on the surface. In order for this chemical reaction to take place, the substrate must be alkaline (high pH) and contain calcium hydroxide. Because silanes do not change the skid or slip resistance of concrete, they are ideal for surfaces such as walkways, bridges, and roadways. Silanes are not effective in sealing other substrates such as natural stone, clay, brick, or wood.Because silanes consist of smaller molecules than siloxanes, they will typically penetrate deeper than siloxanes and thus perform better on dense surfaces such as poured-in-place and pre-cast concrete. A consequence of this molecular size is that silanes are quite volatile. Therefore, the solids content of a silane water repellent should be high enough to compensate for the evaporation of reactive material during application and curing.Siloxane-Based Water Repellents. Siloxanes have a slightly larger molecular structure and are somewhat effective on substrates up to medium porosity, such as heavyweight, smooth-faced, and concrete block. Despite being closely related, the siloxane-based chemical composition does not encourage rapid evaporation. The solids content and cost of a siloxane-based sealer is typically lower than that of silanes.Unlike silanes, siloxanes are not dependent on substrate pH to react. They can react with atmospheric moisture, as well as any moisture in the substrate, to form the hydrophobic resin. For this reason, siloxanes are ideal for treating non-cementitious building materials such as brick, stucco, and stone.CLOSING THOUGHTBy using the latest technologies, concrete contractors can combat water-related damage and ensure optimal concrete protection. about the authorJennifer Crisman is director of marketing services at The Euclid Chemical Company, a leading manufacturer of specialty concrete and masonry construction solutions.

Designed with innovative technology to meet the user’s needs, this new range answers the growing issues of life, durability, strength, and speed.Concrete building trends continue to grow at a fast pace, driven by both the robust economy and building codes for commercial and residential sectors. The building materials industry is creating higher-strength concrete and rebar forcing power tool manufacturers to develop stronger, more powerful drills. However, current drilling solutions in the marketplace have not kept up with these growing trends: the ability to handle high-heat, tough to drill applications such as rebar, or being fast enough to minimize labor costs.For years, Diablo has received end-user feedback requesting state-of-the-art products to address durability, strength, speed, and labor costs, all of which are not currently offered. Diablo’s first-ever complete range of Rebar Demon™ 4-cutter full carbide head hammer drill bits is the ultimate solution for drilling fast, precise holes without the need of changing to a rebar cutter to drill reinforced concrete, delivering extreme savings in time and money.Diablo’s revolutionary range of SDS-Plus and SDS-Max Rebar Demon™ 4-cutter full-carbide head hammer drill bits are the only bits designed to be the most durable, fastest, and coolest solutions on the market. The Rebar Demon bits feature up to 2X more Dura-Carbide to withstand up to 1800°F of intense heat whereas standard bits fail at 800°F. Diablo’s impact resistant 4-cutter full-carbide head withstands the stress of high-powered hammer drills and the impact of rebar by taking small bites of rebar to deliver controlled carbide wear, reduced vibration and up to 7X longer life.

AUGUST 2020 www.mcsmag.com62What have you seen in your business since the start of the pandemic? TOOHEY: Very strong start to year and then the bottom fell out mid-March. Began to see improvement in May, led by our residential products. The number of orders received never really declined, just the quantity of products on those orders. Our distribution partners continued to order but were keeping inventories at a minimum.Have you seen some parts of the country rebounding faster than others? Can you go into more detail about that? TOOHEY: Business has been fragmented geographically. Sales on the West Coast and in the South have been strong. Not sure how the recent flare-ups of COVID-19 in those regions will impact things going forward. The Upper Midwest and New England have been improving; Pennsylvania and Massachusetts seem to be rebounding after being one of the states hardest hit by shutdowns. It seems like things are slowly getting back to some level of normalcy. What do you expect to see in the next 6 months? In the next 18 months? TOOHEY: I think Q3 will be solid due to pent up demand and taper off a bit in Q4. Various projections show construction slowly improving into 2021 but the impact of the pandemic this summer and fall is a great wild card. I’m also concerned about projects that were deferred due to COVID-19. I think some of those are just going to go away.Are certain sectors of construction—i.e., hospitals, commercial buildings, schools—seeing a more rapid rebound than others? TOOHEY: Education and infrastructure seem to be very busy. The summer historically is the busiest time in our business for school construction and everyone is operating, and has to, on the premise that kids will be back in school in the fall. A lot of funding was already in place for water and waste treatment construction and these projects are also proceeding at a steady clip.I think it’s fair to say the pandemic caught everybody with their guard down. What are your key takeaways from the pandemic, and what processes do you think will change in the building and construction industry as we move forward? TOOHEY: I think everyone has learned to operate remotely and found that, for the most part, it can be done quite successfully. Safety has always been critical in the construction industry, and I think the pandemic has only heightened this. Everyone seems refocused on the importance of PPE and other safety protocols to protect employees. Going forward, it will be interesting to see what kind of impact the shift to working remotely has on commercial construction. Over the next several years, we will likely see many organizations downsize their office footprint to reflect having fewer people on site. If someone had told you at the beginning of 2020 that a pandemic would wreak havoc on the American economy and impact every industry in some way, shape, or form … would you have believed it? How have companies in the construction sector fared with the “new normal?” Here’s what Mike Toohey, general manager of The Bilco Company, shares in five questions.for more information Mike Toohey has been with The BILCO Company for 32 years and started on the residential side of the business. For the last 27 years, Mike has worked on the commercial/architectural side of the company, most recently as director of architectural sales & marketing.
