Building in Harris County
Harris County's 134 mph design wind speed is in the elevated-inland-coast band. This meaningfully changes the steel package: heavier columns, closer fastener spacing, and often rod-and-cable or portal bracing. Any reputable supplier will engineer to 134 mph for this county, and the price band on this page already reflects that added steel.
Foundation & slab in Harris County
Steel is only half the job — the concrete under it is the other half. The Houston metro sits on expansive Beaumont and Lissie clays that swell and shrink with moisture. A properly designed slab — often post-tensioned or with a stiffened edge and moisture control — is what keeps a metal building square over time. Don't cut the foundation to save money here. The slab range shown in the estimator is a Texas-typical figure; your final number depends on a soils report and the local ready-mix price.
