THE EXACT LOCATION OF EQUIPMENT ROUGH-INS SHALL BE VERIFIED

WITH THE STAMPED APPROVED SHOP DRAWINGS PRIOR TO ANY FIELD

INSTALLATION.

THE MECHANICAL CONTRACTOR WILL BE RESPONSIBLE TO MAINTAIN

EACH PROJECT SPACE IN A NEGATIVE PRESSURIZATION AND PROVIDE

HEPA FILTRATION UNITS AS REQUIRED BY INFECTION CONTROL. IF

NECESSARY CONSULT WITH VA, OR ENGINEER OF RECORD, FOR

SUGGESTED METHODS THAT MAY BE UTILIZED TO ELIMINATE

CONTAMINATED AIR TO OUTSIDE. VISUAL PRESSURIZATION INDICATORS

SHALL BE PROVIDED AT EACH ENTRANCE TO THE CONSTRUCTION ZONE

AND MONITORED DAILY TO INSURE A CONSTANT NEGATIVE PRESSURE

THE ENTRANCES TO EACH CONSTRUCTION AREA. ALL CONTRACTED

WORKERS SHALL BE TRAINED TO VISUALLY MONITOR THESE DEVICES

FOR ADEQUATE NEGATIVE PRESSURIZATION AS THEY ENTER/EXIT THE

CONSTRUCTION AREA. DAILY LOGS SHALL BE KEPT BY THE

MECHANICAL CONTRACTOR TO INSURE CONSTANT PRESSURIZATION

HAS BEEN MAINTAINED.

NEGATIVE PRESSURIZATION SHALL BE MAINTAINED IN EACH

CONSTRUCTION AREA. IF LOCATED ON AN EXTERIOR WALL FANS

SHOULD BE UTILIZED TO EXHAUST AIR DIRECTLY OUT A NEARBY

WINDOW, TAKING PRECAUTIONS TO NOT INTERFERE WITH EXISTING

BUILDING AIR INTAKES, PUBLIC AREAS, ETC. IF NO EXTERIOR WALL IS

AVAILABLE THEN NEGATIVE AIR MACHINES WITH INTERNAL FILTRATION

SHALL BE PROVIDED AND CONNECTION TO THE NEAREST EXHAUST OR

RETURN DUCT AVAILABLE (CONTACT ENGINEER TO VERIFY EXISTING

DUCTWORK CAPACITY PRIOR TO EXHAUST CONNECTION).
