DEMOLITION PLAN

BUILDING A: MECHANICAL

GENERAL NOTES:

HEAVY LINES REPRESENT NEW WORK WHILE

LIGHTER LINES REPRESENT EXISTING PIPING AND

EQUIPMENT.

THE CONTRACTOR SHALL PROVIDE MECHANICAL

INSULATION AS NOTED ON THIS SHEET FOR EXISTING

PIPING SYSTEMS AND EQUIPMENT. ALL INSULATION

SHALL COMPLY WITH SPECIFICATION SECTION 15250.

REMOVABLE PADS SHALL BE USED FOR ALL STEAM

TRAPS, VALVES AND STRAINER ASSEMBLIES UNLESS

SPECIFICALLY NOTED OTHERWISE. USE SPECIFIED

INSULATION THICKNESS FOR EACH SYSTEM UNLESS

OTHERWISE SPECIFICALLY NOTED. FIELD VERIFY ALL

PIPING AND EQUIPMENT SIZES.

FABRICATE AND PAINT ANY AND ALL NEW PIPE

SUPPORTS TO MATCH THE EXISTING SUPPORTS

OUTAGES AND PHASING:

ALL OUTAGES MUST BE SCHEDULED IN ADVANCE IN ACCORDANCE WITH

DIVISION 1 AND THE GENERAL CONDITIONS. TO LIMIT THE DURATION OF

OUTAGES, THE FOLLOWING PHASING HAS BEEN PROVIDED:

INSTALL NEW 8" HPS AND 4" PUMPED CONDENSATE IN BUILDING−7 TO THE

GREATEST EXTENT POSSIBLE PRIOR TO DEMOLITION AND

RECONNECTION OF EXISTING SYSTEMS.

INSTALL NEW AIR COMPRESSOR IN BUILDING−A PRIOR TO COMPRESSED

AIR LINE AND EXISTING AIR COMPRESSOR DEMOLITION IN BUILDING 7.

INDIVIDUALLY REINSTALL EACH VACUUM PUMP IN BUILDING−A PRIOR TO

VACUUM LINE DEMOLITION IN BUILDING−7. ONE VACUUM PUMP SHALL BE

OPERATIONAL AT ALL TIMES.

PERFORM CONNECTIONS TO EXISTING LABORATORY UTILITIES LOCATED

IN THE 2ND FLOOR CORRIDOR CEILING OF BUILDING−6 AT ONE TIME.
