Pallet racking in Humble, TX.

Three things. First, the economics invert: refrigerated and frozen cubic feet cost far more to build and run than ambient, so density systems like push-back, pallet flow and drive-in usually pay for themselves where in an ambient building they might not. Second, the components and finishes have to suit the temperature regime and the wash-down or defrost cycle, because ordinary painted steel in a freezer or at a freezer threshold does not last. Third, the transition zone is where the trouble is — condensation and frost at the dock and freezer line attack base plates and anchors first, so that zone gets specified and inspected harder than the rest of the system.

Yes. The forwarder profile is distinctive: consignments are small, varied and time-critical, dwell time is short, and the operation is judged on how fast something can be found and moved rather than on how much fits. That points to selective rack with an accessible pick face, shelving or carton flow for loose freight, and enough staging depth at the dock line to build and break air pallets without blocking aisles. We design from the throughput and dwell profile rather than from pallet count, which for this kind of operation is close to the wrong metric.

No. Humble is its own incorporated city, and the surrounding area is largely unincorporated Harris County — which is a third jurisdiction again. That matters for high-piled combustible storage: unincorporated Harris County requires a construction permit and an operational permit above 500 square feet including aisles, with annual renewal of the operational permit, while the City of Houston requires an operational permit above 2,500 square feet. Texas has no statewide commercial building-code enforcement agency, so the local office is the authority, and we confirm which one from the parcel before drawings are issued.
