QUCIK GUIDE • FORMED CONCRETE SURFACES2Quick Guide Formed Concrete SurfacesThere are four Concrete Surface Categories (CSC):• CSC 1: Lowest classifications• CSC 4: Highest classificationsConcrete surface levels are planned for individual parts of the structure or the entire surfaces to reflect owners’ needs, desires and budget.EXAMPLES• Basement Walls• Industrial Structures• Electrical & Mechanical Rooms• Stairwells• High-End Building Exteriors• Religious Structures / Museums• Monumental or Landmark StructuresCSC 1 CSC 1 or CSC 2 CSC 1 or CSC 2 CSC 1 or CSC 2 or CSC 3CSC 3 or CSC 4 CSC 3 or CSC 4CSC 4Pictured BelowCal Poly SLO Residential CommunitySan Luis Obispo, CA
