THE PROJECT IS LOCATED AT THE NATO ALLIED COMMAND TRANSFORMATION BUILDING ON NAVAL STATION NORFOLK IN NORFOLK, VIRGINIA. THE SCOPE OF WORK INCLUDES THE REMOVAL AND REPLACEMENT OF FIVE MAKE-UP AIR HANDLING UNITS LOCATED ON THE ROOF. THE NEW MAKE-UP AIR HANDLING UNITS WILL UTILIZE WATER COOLED DX FOR COOLING AND RECONNECT TO EXISTING CONDENSER WATER PIPING. NATURAL GAS WILL BE USED FOR HEATING AND WILL REQUIRE NEW GAS PIPING TO BE ROUTED TO THE INDIVIDUAL UNITS FROM THE UTILITY SERVICE ENTRANCE. TO GET NATURAL GAS PIPING TO THE ROOF OF THE FIVE STORY BUILDING, A NEW PIPE CHASE WILL HAVE TO BE BUILT IN A CORNER OFFICE ON FLOORS ONE THROUGH FIVE. EXISTING ELECTRICAL POWER CONNECTIONS WILL BE REUSED TO THE GREATEST EXTENT PRACTICAL.
