Mechanical, electrical, and plumbing trades all want something from the slab before we pour it. Electrical wants conduit stubbed up in the right spots for panels and floor boxes. Plumbing wants sanitary and water lines roughed in under-slab before we place. Mechanical wants sleeves for ductwork and refrigerant runs. If those trades aren't sequenced against our pour schedule, somebody ends up core-drilling a finished slab or waiting weeks for a change order — and on a Hunt County distribution or manufacturing build, that's real money sitting idle.
We coordinate MEP subcontractors on the projects where we're pouring the concrete, whether that's a tilt-wall warehouse, a manufacturing floor, or a retail build-out. That means walking the underground plumbing and electrical layout with the trade before we excavate, confirming sleeve and conduit locations against the structural and MEP drawings, and holding a firm sequence: underground rough-in, inspection, backfill, then our slab goes down on top of it — once, correctly.
Greenville's clay soils and the City of Greenville's inspection process both reward getting this sequence right the first time. Expansive clay makes trench backfill and compaction unforgiving if it's rushed, and re-opening a slab for a missed conduit run means fighting the same soil twice. We build in the inspection windows the city requires for underground utilities before we schedule concrete placement, so the trades aren't racing our pour crew and our pour crew isn't racing an inspector.
This isn't design work — we're not engineering your electrical service size or your plumbing fixture count. What we manage is the physical interface between MEP rough-in and the concrete around it: where the sleeves go, when the trench gets backfilled, and when the slab can safely go down without conflict.
