Building in Montgomery County
At 120 mph design wind speed, Montgomery County sits one tier above the inland baseline. Engineers respond with heavier gauge or tighter purlin and girt spacing rather than a redesign, so the wind premium is modest. Expect the building to require stamped drawings that reflect the 120 mph load if you're pulling a permit near Conroe.
Foundation & slab in Montgomery 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.
