Underslab MEP rough-in and inspection coordination with mechanical, electrical, and plumbing subs
Mechanical, electrical, and plumbing rough-in is where a lot of commercial concrete schedules quietly fall apart — not because any one trade is behind, but because underslab plumbing, conduit routing, and floor box locations didn't get locked down before the pour crew showed up. We coordinate MEP trade scope on our concrete projects, working directly with the mechanical, electrical, and plumbing subcontractors to confirm rough-in locations, sleeve and conduit placement, and inspection sign-offs before concrete goes down — so nobody's cutting a trench through a cured slab three weeks into the project.
That starts with a coordination review of the MEP drawings against our own pour plan: underslab plumbing runs and floor drain locations checked against structural footing and grade beam layouts, electrical conduit and floor box placement confirmed against the tenant's actual equipment layout rather than a generic template, and trench drain and utility sleeve locations verified before formwork goes in. On projects with tight underslab utility runs — data centers, food service buildouts, and manufacturing floors with process equipment scattered across the slab — we sit in on the trade coordination meetings specifically to flag conflicts between the concrete pour sequence and MEP rough-in inspections, because a missed underground inspection can hold up a pour by days.
We run pre-pour walks with the MEP subcontractors present, not only a drawing review at a desk. Standing on the actual formwork with the plumber and electrician catches problems a coordination drawing doesn't: a floor box that's six inches from where the equipment actually lands, a conduit run that conflicts with a rebar mat, an underslab plumbing tie-in that needs a different invert elevation than what's shown. Fixing that on the formwork costs an hour. Fixing it after the pour costs a saw, a jackhammer, and a week.
For general contractors managing multiple subs on a fast-tracked Fort Worth commercial or industrial project, this coordination role is often the difference between a pour that happens on the date it's scheduled and one that slips because an inspector couldn't sign off underslab work in time. We don't run the MEP trades — we make sure their scope and our concrete scope are talking to each other before either one is locked in.
Representative project scenario — not a specific client reference.
Scope
Underslab MEP rough-in coordination for a 40,000 sq ft manufacturing floor with process equipment
Client Situation
A general contractor's plumbing and electrical rough-in drawings hadn't been field-verified against the actual equipment layout, risking a pour date slip if conflicts surfaced after formwork was set.
Our Approach
We walked the formwork with the plumbing and electrical subs before pour, relocated two floor boxes and one drain tie-in to match the confirmed equipment plan, and coordinated the underground inspection to close out the day before the scheduled pour.
Expected Outcome
Pour proceeded on the original scheduled date with zero rework or core-drilling required after cure.
Educational content only. Not engineering, legal, or trade-specific design advice. MEP installation must be performed by licensed mechanical, electrical, and plumbing contractors in accordance with applicable code and inspection requirements.
No. We coordinate MEP trade scope as it relates to our concrete pours — rough-in locations, sleeve and conduit placement, and inspection timing — working directly with licensed mechanical, electrical, and plumbing subcontractors who perform the actual trade work.
Underslab plumbing, conduit, and floor box locations that aren't verified before pour often need to be corrected after the fact through core-drilling or saw-cutting, which costs significantly more time and money than catching the conflict on the formwork.
Yes. We walk formwork with plumbing and electrical subcontractors before pour to verify rough-in locations against the actual equipment layout, not only the coordination drawings.
Projects with dense underslab utility runs — food service buildouts, data centers, manufacturing floors with process equipment, and tenant improvements with new plumbing or electrical rough-in — benefit most from this coordination.
Underground MEP inspections often have to be signed off before a pour can proceed. Coordinating rough-in locations and inspection timing ahead of the pour date reduces the chance of an inspection delay holding up the concrete schedule.
