Project Scope: Heavy-duty commercial plumbing installation and infrastructure routing for the Loyalhanna Dam Service Bridge Rehabilitation Project, executed for the U.S. Army Corps of Engineers in Saltsburg, PA.
Our team completed a complex industrial drainage overhaul, featuring a waterproof membrane installation on top of the dam structure, a 4-inch PVC drain stubbed through the parapet wall, and a specialized commercial trench drain layout. Downstairs, we engineered and installed a 6-inch area drain system that stubs cleanly through the concrete ceiling, connecting to a heavy-duty 6-inch PVC horizontal drain branch and main vertical stack assembly to manage high-capacity storm water runoffs.
