GENERAL OBJECTIVE: INTENT IS TO REPLACE BROKEN 6" UNDERGROUND WATER SERVICE, AND GALVANIZED 4" COLD WATER (CW) PIPING IN AREAS INDICATED; REMOVE INSULATION FROM HOT WATER (HW) AND CIRCULATING HOT WATER (CHW) SYSTEMS THAT SHALL REMAIN, AND REINSULATE ALL WATER SYSTEMS AFFECTED. ACCESS REQUIRES REMOVING OF CEILING AND CEILING MOUNTED DEVICES IN SOME AREAS, AS WELL AS ASBESTOS ABATEMENT. FIRE SPRINKLER SYSTEMS EXIST BELOW CEILING IN THIS AREA, AND SHALL REMAIN IN PLACE. HARD DECK CEILING SHALL BE REPLACED WITH NEW 24"X48" LAY-IN ACOUSTICAL TILE AND GRID. SHUTDOWNS SHALL BE SCHEDULED EVENINGS AND WEEKENDS OUTSIDE OF OPERATING

HOURS.
