About this file
This construction phasing plan outlines the replacement of two air handling units at a Department of Veterans Affairs medical facility. The project involves demolishing the existing AHUs serving the 5th floor PCT clinic and 4th floor pharmacy areas. A new AHU-60 unit will then be installed on the existing concrete platform and connected to ductwork serving the 5th floor clinic and roof penetrations. The plan details the phasing of moving clinic occupants to swing space, conducting pre-construction airflow measurements, demolishing the old units, installing and commissioning the new AHU-60, and returning occupants to the renovated space. Contractors must submit a comprehensive phasing plan for approval prior to commencing work.
