HVAC Trade Coordination

Concrete work and HVAC rough-in cross paths more often than people expect — slab penetrations for mechanical curbs, housekeeping pads for rooftop and ground-mounted units, trenching for refrigerant lines, and equipment pad layout that has to be locked before we place a slab. We coordinate a licensed HVAC subcontractor as a managed sub-scope on projects where we are already running the concrete and site package, so an owner or general contractor gets one point of contact instead of chasing two separate schedules.

This is a coordinated scope, not a self-performed trade: we bring a vetted mechanical subcontractor onto the project, hold them to our schedule, and fold their equipment pad and slab-penetration requirements into our concrete sequencing. For a general contractor bidding a warehouse or manufacturing build in Arlington, that means the mechanical package shows up already synced to the concrete critical path instead of surprising the schedule two months in.

The failure mode we are built to avoid is the one every GC has seen: a mechanical sub shows up wanting a curb or pad that nobody told the concrete crew about, and now there is a cut-and-patch job on a slab that was already finished. We ask for equipment cut sheets before we form the slab, not after, so pad dimensions and penetration locations are already accounted for on pour day.
