📋 MY SCOPE
Connect to existing 2-1/2" CW domestic water service. Install BFP in metal case per coded note. Run new 2-1/2" CPVC distribution header to all restrooms and equipment per P1.0 and P2.1 riser
Full restroom buildout — Men's (rm 114), Women's (rm 113), Family RR (rm 133): 14 WC, 3 UR, 10 LAV, 5 FD per enlarged plans P2.0. All fixtures fully piped per P2.1 riser diagrams
Connect to existing 4" sanitary — field verify routing, inverts and direction before any rough-in. Provide alternate bid for lift station if existing sanitary is not usable. Furnish all new sanitary piping per risers
Install EWH-1 (A.O. Smith DEL-20, 20 gal air-source heat pump) and EWH-2 (DEL-10, 10 gal electric) on shelves above service sinks per P2.2 detail. Provide seismic strapping, T&P relief, expansion tank (Amtrol ST-5), isolation valves, and drain pan per coded notes
Install Taco 007 recirc pump (RP-1) with balancing valve (Flow Design ICSS075/ICSS050, set 1.0 GPM), aquastat with 24V thermostat. Route 3/4" RHW return per P2.1 riser. Install in-line Wilkins 40XL check valve on SS water supplies
Install 4 water coolers: EWC-1 (3x Elkay EZSTL8WSLK) and EWC-2 (1x Elkay EZWS(M)8K). Connect 1/2" CW and waste per P2.1 schedule
Install 2 FIAT service sinks (SS) and 1 Elkay lounge sink (SINK). Run 3/4" CW and HW per riser. EWH-2 serves breakroom/lounge area
Inspect existing sump pump — check, repair, or replace as needed. Connect existing trench drains in building to sump pump discharge. Coordinate sump pump discharge routing with GC
Replace existing canopy/roof storm drain conductors with new PVC piping per coded notes. Connect BFP in metal case on storm system per note 4. Install RD-1 (J.R. Smith 1330 canopy roof drain, 3") per plan
Install 3 non-freeze wall hydrants (NFWH) per plan at 3/4" CW connections. Hose bibb (HB) at roof hatch within reach per note on P1.0. Route 4" VTR through roof per vent thru roof detail P2.2
Coordinate condensate drain routing from heat pump RTUs on roof with mechanical contractor. All plumbing insulated per spec. CPVC not to run through return air plenums
🚩 RED FLAGS
Existing 4" Sanitary — Field Verify Before Any Work
Plan explicitly states: verify existing sanitary routing, size, and inverts before connection. There are two separate connection points called out on P1.0. If invert is not deep enough, an alternate bid for a duplex sewage grinder lift station is required. Carry this as an alternate.
Sump Pump — Inspect, Repair or Replace
Existing sump pump must be checked and confirmed working. Plan coded note 16 says contractor shall check, repair, or replace as needed. Price the replacement (Zoeller or equal) as an allowance — you won't know until you're on site.
Existing Trench Drains — Contractor to Connect to Sump
Existing trench drains in the building must be connected to new sump pump discharge. Field verify quantity, condition, and routing of trench drains before pricing. This is an unknown until you walk the space.
CPVC Above Grade — Cannot Run in Return Air Plenums
Spec explicitly prohibits CPVC in return air plenums. On a large retail TI with open ceilings this is a real coordination risk. Identify any plenum areas with HVAC contractor before roughing in water lines.
EWH-1 Heat Pump WH — Seismic Bracing + Title 24 Requirements
A.O. Smith DEL-20 is an air-source heat pump water heater. Title 24 (P4.0) requires seismic bracing per local codes. Heat pump unit also needs 120V electrical confirmed with EC before purchase. Backup heat operation has specific insulation and control requirements per P4.0.
Gas — No Service Available, Capped
Coded note states: connect to existing gas piping with shut-off valve. Natural gas is capped and there is no gas meter. Confirm with the GC and owner whether any gas-fired equipment is planned — if not, gas scope is just the cap. If gas service is added later, that is a separate future scope.
BID VERDICT
BID WITH QUALIFICATIONS
Large retail TI with full restroom buildout — 14 WC, 3 UR, 10 LAV across Men's, Women's and Family RR. Two heat pump water heaters, recirc system, and several unknowns around existing sanitary, sump pump, and trench drains. Carry the lift station as an alternate and the sump pump as an allowance before submitting your number.
