PLUMBING DEMO NOTES

A. LOCATIONS AND DIMENSIONS OF EXISTING FACILITIES IDENTIFIED ON THIS

DRAWING ARE APPROXIMATE AND REPRESENT THE BEST AVAILABLE

INFORMATION BASED ON A COMBINATION OF FIELD INVESTIGATIONS AND

VARIOUS DESIGN AND RECORD DRAWINGS AVAILABLE AT THE TIME OF

DESIGN. FIELD VERIFY LOCATIONS AND DIMENSIONS PRIOR TO ORDERING

EQUIPMENT AND DURING PERFORMANCE OF THE WORK. PROVIDE

DEMOLITION WORK, NECESSARY FITTINGS, TRANSITIONS, AND OTHER

COMPONENTS AS REQUIRED FOR A COMPLETE AND FUNCTIONAL

INSTALLATION OF NEW SYSTEMS AT NO ADDITIONAL COST TO THE OWNER.

B. EXISTING PLUMBING EQUIPMENT, FIXTURES, AND PIPING SHOWN AS DARK

AND DASHED SHALL BE DEMOLISHED. EXISTING PLUMBING EQUIPMENT,

FIXTURES, AND PIPING SHOWN LIGHT SHALL REMAIN UNCHANGED.

C. THE PLUMBING CONTRACTOR SHALL COORDINATE SALVAGE OF REMOVED

EQUIPMENT IN GOOD CONDITION WITH THE OWNER. THE PLUMBING

CONTRACTOR SHALL DISPOSE OF UNWANTED EQUIPMENT.

D. COORDINATE WITH GENERAL CONTRACTOR TO PATCH AND REPAIR ROOF

AND WALL ASSEMBLIES ASSOCIATED WITH PLUMBING DEMOLITION.

E. CONCRETE SLAB CUTTING REGIONS SHOWN ON DRAWINGS ARE

APPROXIMATE AND MUST BE FIELD COORDINATED PRIOR TO THE CUTTING

OF THE SLAB.

F. PROTECT EXISTING BUILDING ELEMENTS DURING DEMOLITION WORK.

COORDINATE WITH OTHER TRADES TO ENSURE NO EXISTING

EQUIPMENT/PIPING TO REMAIN IS DAMAGED DURING THE DEMOLITION

WORK.

KEY NOTES:#

1. COMPLETELY DEMOLISH THE EXISTING SINK, INCLUDING ALL TRIM TO THE

WALL. FURNISH AND INSTALL A PERMANENT CAP ON DCW, DHW, AND SAN.

2. COMPLETELY DEMOLISH THE EXISTING SINK, INCLUDING ALL TRIM TO THE

WALL INCLUDING ANGLE VALVES. PREPARE THE EXISTING DCW, DHW, AND

SLAB-ON-GRADE, AND TERMINATES THROUGH THE WALL AT

APPROXIMATELY 4'-6" AFF. NO WORK.

4. EXISTING AC-1 PUMPED CONDENSATE LINE TO REMAIN, NO WORK.

EXISTING 3/8" POLY LINE IS ROUTED ABOVE THE LAY-IN CEILING.

5. EXISTING WALL CLEAN OUT TO REMAIN. SEE CONSTRUCTION DRAWINGS

FOR NEW WORK.

6. PLUMBING CONTRACTOR SHALL COORDINATE WITH THE SITE CIVIL

CONTRACTOR TO RESTORE EXTERIOR SANITARY SEWER SERVICE TO THE

EXTERIOR SEWER MANHOLE. NO WORK IS ANTICIPATED FROM THE

FIXTURE UP TO AND INCLUDING TO THE BUILDING FOUNDATION WALL.
