What Tenant Finish Plumbing Includes
Tenant finish work connects a new layout to a building that is already standing. We field-verify what is there, then build only what the suite needs.
Tie-Ins to Existing Risers
New waste, vent and domestic water branches connected to the building's existing risers and mains.
Restrooms & ADA Fixtures
Restroom groups and accessible fixtures laid out and set for the suite's occupancy.
Break Rooms
Sinks, dishwasher and ice-maker connections, and water heaters for staff break areas.
Medical Gas
Med gas piping for dental and medical suites, installed by ASSE 6010 certified brazers.
Restaurant Grease Interceptors
Grease interceptors and kitchen waste for restaurant tenant finish, ready for scheduled cleaning.
Coordinating Tenant Build-Out Plumbing in Occupied Buildings
Most build-outs happen next to tenants who need water and drains all day. We plan the disruptive steps before a valve turns.
Shutdown Planning
Water shutdowns are noticed, scheduled and communicated to the building engineer in advance.
Core Drilling
Core drilling and selective demo scheduled around tenant hours where the building requires it.
Trade Coordination
Rough-in sequenced with the GC and other trades so the suite stays on its turnover date.
Match the plumbing scope to the tenant
A restaurant fit-out combines kitchen drainage, grease interception, equipment connections and water heating. Retail and office suites commonly focus on restroom groups, accessible fixtures and break-room connections. Medical and dental spaces add clinical sinks, sterilization and equipment rough-in; medical gas belongs in the scope when specified, not in every office build-out. Verify fixture locations and retained risers before treating these uses as interchangeable.
Coordinate submittals, shutdowns and inspections with the GC and building engineer. Inspect concealed piping before finishes close. Send the tenant type, plans link, bid due date, equipment information and schedule. Project proof shows actual scopes, not a standard duration or promised turnover date for a different suite.
