Ground Phase

Rough-In, sewer and waterlines involves installing underground pipes that connect the building to the main water supply and sewer systems. This phase includes trenching, laying pipework, and ensuring proper slope and alignment before the foundation is poured.

Vanguard and Topout

The Vanguard phase involves installing the main water and waste lines through the foundation or slab before framing begins. The Topout phase follows, where above-ground supply and drainage pipes are installed after framing to prepare for final fixture connections.

Trim-Out

Final walk-thoughs and ensuring fixtures are installed according to plumbing code. This includes checking for leaks, proper water flow, and verifying that all systems meet safety and compliance standards. Any necessary adjustments are made to guarantee a fully operational and code-compliant plumbing system.
