T&B CONTRACTOR WILL CHECK THE AIR BALANCE AFTER THE RETURN IS BLOCKED TO MAKE SURE THE PRESSURIZATION OF THE ADJACENT SPACES ARE MAINTAINED AS REQUIRED. 3. THE A/C SUPPLY AND RETURN AIR TO THE CONSTRUCTION AREA TO BE ADJUSTED AS REQUIRED. ONE PORTABLE HEPA FILTER NEGATIVE AIR MACHINE(FA2000EC) SHALL BE INSTALLED .TO CLEAN THE AIR IN THE ROOM. THIS MACHINE SHALL FILTER AIR. AIR QUANTITY SHALL BE ADJUSTED TO MAINTAIN A MINIMUM OF 0.02" W.g. NEGATIVE PRESSURE VISUAL PRESSURE INDICATORS (ADI- 69 -V -N) WILL BE INSTALLED AT THE ENTRANCE. AFTER INSTALLATION OF CONSTRUCTION BARRIER WALLS AND THE ABOVE MEASURES, A CERTIFIED TEST AND BALANCE FIRM SHALL CONFIRM THAT THE ABOVE ITEMS ARE IN PLACE AND WORKING PRIOR TO STARTING DEMOLITION.
