A tenant improvement, a restaurant build-out, a clinic suite, an addition or a new shell building needs its water supply run before the walls close: the connection to the service entry or the existing main, the mains and branches to every fixture location, hot water from the heater or loop, isolation valves, and capped stubs tested and ready for inspection. It's rough-in work, and done right it's the part of the building nobody ever thinks about again.

We run commercial supply in copper or PEX-A to suit the occupancy and the code, sized for the fixture count and the distances, with isolation valves at every branch so a future tenant change doesn't shut down the neighbor. Where the project needs a new or upsized service from the street or the private main, we trench and install it with our own equipment as part of the same scope. We coordinate with the general contractor, the mechanical and electrical trades and the fixture installer, and we pull the plumbing permit and schedule the inspection as a registered general contractor with licensed plumbers on the team.

The routing is documented and handed to the owner, so that when the next tenant improvement comes around the lines are where the drawing says they are.
