Restaurant plumbing model

All waste, vent, cold and hot water from the plumbing sheets, routed at real elevations. Every run is tagged with its size and length (LF). Click any pipe for material, elevations and slope.

Measured from the model centerlines, stacks and drops included. Add 10–15% for fittings and waste.

Assumptions and RFIs

Routing is taken from the P-2.0 and P-2.1 linework at 1/4" = 1'-0" and placed on the A-4.1 floor plan grid. Positions are within about 3 in.
Depths and ceiling heights are not on the plans. Inverts are set by slope from the sewer back to each fixture, and the ceiling elevations above are assumed.
Vent headers are drawn offset from the stacks on P-2.0 (some fall outside the east wall). The model runs them directly above the stacks.
Women's water closet on stack R15 sits in the Rev 1 cloud, but key note 1 makes that stack 2". A water closet needs 3" minimum. RFI.
Grease interceptor is 1,500 gal per P-1.1 and P-2.2. The sizing table (22 DFU) supports 1,000 gal. RFI already on the bid list.
Existing water meter, RPZ and service come from the P-3.0 isometric only. Their locations outside the south wall are shown schematically.
Sewer tie-in from the sample box to the existing lateral is modeled as new. P-2.2 draws it the same as existing; verify in the field.
Gas: no gas piping is shown. P-1.0 and P-1.1 only carry generic gas details, and the water heater, fryer and induction cooker are electric. No gas is modeled.
Fixtures served by four kitchen stacks are not tagged on P-2.0 (back counter FD, prep-area FS at K08, cook-line FS). They are inferred from the branch and trap primer lines.
