PRIOR TO DEMOLITION, MEASURE AND RECORD AIR & WATER QUANTITIES IN UTILITIES REQUIRED TO MAINTAIN OPERATION WITHIN AND BEYOND EACH DEMOLITION PHASE UNTIL AFFECTED AREAS ARE DEMOLISHED. MAINTAIN THESE QUANTITIES THROUGHOUT EACH DEMOLITION PHASE. 2. MAINTAIN EXISTING AIR HANDLING UNITS IN OPERATION UNTIL ITS RESPECTIVE DEMOLITION PHASE IS COMPLETE. BLANK OFF AND SEAL RETURN AIR INTAKES SERVING EACH DEMOLISHED AREA IN ORDER TO PREVENT GENERATED CONSTRUCTION DEBRIS FROM BEING RECIRCULATED TO OCCUPIED SPACES DURING DEMOLITION -CONSTRUCTION PHASE. BLANK OFF AND SEAL ANY SA, RA AND / OR EA DUCTS BEING DEMOLISHED AND REMAINING WITHIN THE CONSTRUCTION AREA. 3. MAINTAIN NEGATIVE RELATIVE AIR PRESSURE IN DEMOLITION PHASE AREA. MINIMUM HEPA-FILTERED EXHAUST AIR QUANTITY SHALL BE 0.5 TO 0.75 CFM/SQ.FT. UTILIZE MULTIPLE NEGATIVE AIR UNITS, AS NECESSARY, TO MAINTAIN NEGATIVE PRESSURE. PROVIDE REQUIRED MAKE-UP AIR FROM A SEPARATE SOURCE. FANS IDENTIFIED TO BE DEMOLISHED, IN DEMOLITION AREA, AND / OR EXISTING ROOF EXHAUST FANS AND THEIR ROOF OPENINGS MAY BE UTILIZED FOR NEGATIVE AIR DISCHARGE UNTIL DEMOLITION PHASE IS COMPLETE. DO NOT UTILIZE EXISTING EXHAUST RISERS THAT SERVE OTHER SPACES OR OTHER LEVELS IN BUILDING. 4. VERIFY NEGATIVE RELATIVE AIR PRESSURE IN THE CONSTRUCTION SPACE BY PROVIDING A MAGNAHELIC PRESSURE GAUGE AND MAINTAINING A WRITTEN LOG, TAKEN AT REGULAR INTERVALS, POSTED FOR REVIEW AT SITE OF CONSTRUCTION. 5. DEMOLISH ALL DUCTWORK, PIPING AND ANCILLARY DEVICES WITHIN AREA OF PHASING PLAN UNLESS OTHERWISE NOTED. ALL BRANCH DUCTS BEING DEMOLISHED FROM MAIN TRUNK DUCTS SHALL HAVE BRANCH CONNECTION OPENINGS PATCHED, SEALED AND INSULATED TO MATCH EXISTING DUCTWORK. 6. DEMOLISH ALL ABANDONED DUCTWORK, DAMPERS, PIPING AND ANCILLARY DEVICES IN DEMOLITION AREA UNLESS OTHERWISE NOTED. PATCH AFFECTED WALLS TO MATCH EXISTING OR NEW CONSTRUCTION, AS PROJECT DICTATES. 7.
