Structural Engineer in Katy, TX
Katy is one of the fastest-growing parts of the Houston region, spreading across Harris, Fort Bend, and Waller counties with communities like Cinco Ranch and a steady stream of new homes, schools, retail, and industrial space along I-10 and the Grand Parkway. PRIMECOST provides PE-stamped structural engineering for Katy homeowners, builders, and developers.
Because Katy-area properties may sit inside the City of Katy, in another municipality, or in an unincorporated part of one of three counties, the reviewing authority varies by address. We prepare drawings for the jurisdiction your project actually falls under.

What We Plan For in Katy
New construction foundations
Katy’s flat terrain and clay soils call for slab designs that handle shrink and swell. We design conventional and post-tensioned slab foundations to suit the soils report.
Drainage and flat sites
Flat lots drain slowly, and poor drainage is a common cause of foundation problems. Our evaluations include drainage recommendations alongside structural findings.
Warehouses and light industrial
Growth along I-10 and the Grand Parkway brings tilt-wall and pre-engineered metal buildings. We provide structural review, foundation design, and permit support for these projects.
