Caspian rough-ins custom homes and multi-unit builds across the GTA — plumbing and mechanical to the consultant's drawings, delivered on the date we committed so drywall doesn't sit waiting on us. Every install is OBC-compliant and passes inspection the first time. One project manager per site from kickoff through commissioning, with daily logs and weekly progress updates so the builder always knows where rough-in stands.
Plumbing, mechanical, hydronic, snowmelt, controls pre-wire — Caspian handles the entire rough-in package under one trade, so there's one schedule, one PM, and one signature on the inspection card.
Hot and cold supply runs, complete DWV (drain-waste-vent) stacks, fixture branches, and venting to OBC. Sleeved through walls and floors before pour, pressure-tested before drywall.
Boiler and furnace set, ductwork run to consultant drawings, refrigerant line-set for split and VRF systems, condensate and combustion venting. Equipment staged for trim-out without rework.
In-slab PEX layout for radiant floors, manifold locations coordinated with framing, zone valves and circulator pre-wire, pressure-tested before concrete and signed off in writing.
Driveways, walkways, ramps, and entry pads — PEX layout to engineered spacing, manifold pits, and supply runs to the mechanical room. We coordinate with concrete so the schedule holds.
Permit submission package on day one. Red-line as-builts maintained through rough-in and handed over with the commissioning binder — clean for the owner, clean for the next trade.
Low-voltage rough-in for thermostats, zone controllers, pumps, valves, and BMS head-end. Pulled with the mechanical so the controls contractor can land terminals without opening walls back up.
Most rough-in problems aren't about pipe — they're about communication, schedule discipline, and paperwork. Caspian is engineered for the four things builders tell us they don't get from a typical sub.
01 — Schedule discipline
We hit the rough-in milestone on the day we said we would, or we tell you a minimum of two weeks ahead with a written recovery plan. No drywall ever sits waiting on a vague "next week" — the GC gets the heads-up early enough to re-sequence the other trades.
02 — First-time inspection pass
Our first-time inspection pass rate is 100% on the work we've documented over the last five years. We don't reschedule inspections, we don't burn a Friday on a re-call, and your drywall crew starts when they said they would.
03 — One PM per site
One project manager owns your site from the pre-construction walk through commissioning. No "different guy each visit" surprises, no re-explaining the riser layout to a new face, no information lost between dispatch and the truck.
04 — Daily logs + weekly photos
Daily logs of crew, scope, and hours filed end of day. Weekly progress photos and a one-page summary every Friday — what's done, what's next week, what's blocking. The GC's site report writes itself, and the owner sees real progress.
A four-step engagement built for GCs and developers who need the mechanical trade to stay out of the critical-path conversation.
We walk the site with the GC, review the consultant drawings, and flag conflicts — beam clashes, riser routing, fixture coordination — before they're permanent and expensive.
Plumbing and mechanical roughed to the consultant drawings. Anything ambiguous comes back as a logged RFI — no field guesses, no rework when the consultant sees it.
We book the inspector, meet them on site, and walk the work. The GC doesn't field that call or shuffle the schedule. Pass the first time, every time.
Once drywall and finishes are done we return for the final fixture set, equipment startup, and system commissioning — handed over with as-builts, O&M manuals, and warranty.
