POISED FOR DELIVERY
TWO PATHS
TO DESIGN-BUILD
SUCCESS
Public agencies are increasingly turning to design-build (DB) to save
time, control costs, and attract skilled builders in a tight market. Based
on Carollo's experience, one DB pattern stands out—the agencies
excelling in DB aren't necessarily the ones bringing the most DB
experience to the table. They're the ones who show up ready.
One of the most common miscon-
ceptions about the DB delivery
method is that it is primarily a
procurement choice. Match the
project to the method, select a
team, sign the contract, and the
benefits follow. But in practice,
DB project benefits accrue
from capability deeply rooted in
organizational readiness.
When teams haven't built that
capability, the familiar challenges
emerge: slower decisions; mis-
aligned expectations between
owner, engineer, and contractor;
unclear roles; and uncertainty
about who owns which risk.
The method itself doesn't resolve
these challenges. Discipline and
alignment do. Teams that make
timely decisions, integrate construc-
tion thinking early, and stay aligned
when conditions shift are the ones
who realize DB's full value.

Applying Lessons Learned
in Baytown, Texas
The Baytown Area Water Authority (BAWA) is
expanding its East Surface Water Treatment Plant
(ESWTP) from 6 to 12 mgd via progressive DB.
The expanded plant will meet growing water
demands, enhance system reliability, and
support regional planning.
This smaller-scale DB project is drawing
on lessons learned by team members
involved in other DB projects in the region,
including the 320-mgd expansion of Houston's
Northeast Water Purification Plant.
While the ESWTP is more than an
order of magnitude smaller than
the $2 billion Houston project,
the team is leveraging best
practices—such as educating
stakeholders, using
standard-form
contracts, leaning
into collaboration,
and establishing
proven conflict resolution
strategies—to shape the BAWA project.
Expected to be operational by the summer
of 2028, the project's success will not hinge
on its smaller size, but rather on the applied
discipline developed on larger, more complex
work. The BAWA team has engaged stakeholders
early. Local construction realities have informed
design. Decisions are moving quickly. Second-
guessing is rare.
For utilities and partners who have delivered
DB before, this discipline is one of the strongest
arguments for starting with a successful project
and building from there.

It Pays to Invest Early
Working alongside many utilities
that have implemented DB projects,
Carollo has seen readiness built two
ways. Some agencies earn it through
experience—developing discipline
across a series of projects. Others
build it purposefully—structuring
the organization, governance, and
decision-making before the first DB
project begins. Both paths work.
Both rely on intention.
DB is a Delivery Capability,
Not a Procurement Decision
More than just infrastructure, BAWA's
ESWTP expansion is about planning
ahead, collaborating openly with multiple
partners, and building with purpose.
