ALL WORK MUST COMPLY WITH APPLICABLE CODES, STANDARDS, AND PROJECT SPECIFICATIONS.

ENSURE ALL SYSTEMS, REFRIGERANT, OIL, AND ELECTRICAL, ARE MADE SAFE AND PROPERLY ISOLATED

BEFORE COMMENCING ANY WORK.

PROTECT EXISTING SYSTEMS AND EQUIPMENT NOT SCHEDULED FOR DEMOLITION TO ENSURE THEY

REMAIN OPERATIONAL.

NOT ALL PIPING AND EQUIPMENT ARE DEPICTED ON THE DRAWINGS, AS THEY WERE CREATED BASED ON MULTIPLE PROJECTS OVER THE YEARS AND NON-INVASIVE SITE WALKDOWNS. CONTRACTOR MUST THOROUGHLY REVIEW EXISTING SITE CONDITIONS AND BECOME INTIMATELY FAMILIAR WITH THE PROJECT SCOPE. ANY DISCREPANCIES OR QUESTIONS SHOULD BE REFERRED TO THE OWNER AND

ENGINEER OF RECORD FOR CLARIFICATION.

DEMOLITION PHASING:

THE EXISTING AIR HANDLING UNIT (AHU), SHALL BE REMOVED IN PHASES TO MINIMIZE DISRUPTION TO

BUILDING OPERATIONS.

DISCONNECT AND REMOVE ELECTRICAL CONNECTIONS ASSOCIATED WITH THE AHU. VERIFY IF THE

EXISTING ELECTRICAL COMPONENTS WILL BE REUSED OR REPLACED.

REMOVE THE AHU AND ASSOCIATED PIPING. PROTECT SURROUNDING AREAS, INCLUDING DUCTWORK AND

LOUVERS, TO AVOID DAMAGE DURING DEMOLITION.

IN INSTANCES WHERE SYSTEMS SUCH AS OIL LINES OR BOILER BREECHING CANNOT BE FULLY SHUT DOWN DUE TO THEIR CONNECTION TO DOMESTIC HOT WATER SERVICE, THE PROJECT MAY REQUIRE

ADDITIONAL PHASING TO MAINTAIN OPERATIONAL CONTINUITY.

DUCTWORK AND LOUVERS:

EXISTING DUCTWORK AND LOUVERS WILL BE REUSED. PROTECT THESE COMPONENTS FROM DEBRIS AND

DAMAGE DURING DEMOLITION.

CAP OPEN DUCT ENDS TEMPORARILY TO PREVENT CONTAMINATION.

PIPING DEMOLITION:

RECOVER REFRIGERANT PER EPA GUIDELINES BEFORE DISCONNECTING REFRIGERANT LINES. PROVIDE

DOCUMENTATION OF RECOVERY FOR THE PROJECT RECORD.

REMOVE ALL ABANDONED PIPING BACK TO ITS NEAREST ACTIVE CONNECTION OR TO A LOCATION

DESIGNATED BY THE OWNER.

ELECTRICAL DEMOLITION:

VERIFY WITH THE OWNER'S REPRESENTATIVE WHETHER THE EXISTING ELECTRICAL CONNECTIONS WILL

BE REUSED OR REMOVED.

DISCONNECT POWER AND CONTROLS FROM THE AHU PER LOCAL ELECTRICAL CODES. LABEL AND

IDENTIFY ALL WIRING FOR POTENTIAL REUSE.

CLEAN-UP AND DISPOSAL:

REMOVE ALL DEMOLISHED MATERIALS FROM THE SITE AND DISPOSE OF THEM PER LOCAL REGULATIONS.

CLEAN THE AREA THOROUGHLY AFTER DEMOLITION TO PREPARE FOR THE INSTALLATION OF NEW

EQUIPMENT.

DOCUMENTATION:

SUBMIT A DEMOLITION PLAN AND SCHEDULE TO THE OWNER'S REPRESENTATIVE FOR APPROVAL BEFORE

STARTING WORK.

PROVIDE PHOTOGRAPHS AND WRITTEN DOCUMENTATION OF EXISTING CONDITIONS BEFORE AND AFTER

DEMOLITION
