ANY OTHER UTILITIES, EQUIPMENT, PIPING, AND INFRASTRUCTURE IN THE FACILITY.

4. THE CONTRACTOR WILL CAREFULLY DISCONNECT AND DEMOLISH THE EXISTING VEHICLE EXHAUST EXTRACTION SYSTEMS

INCLUDING BLOWER MOTOR ASSEMBLY AND CONTROLLER, FLEX HOSES, DUCTWORK, HOSE SUPPORT CABLES AND

PULLEYS, AND HARDWARE. REMOVE WIRING AND CONDUIT BACK TO EACH BLOWER MOTOR CONTROLLER. REMOVE WALL

PENETRATION DUCTWORK, UNBOLT AND DEMOLITION EACH BLOWER ASSEMBLY.

5. THE STEEL ANGLE SUPPORT STRUCTURE FOR EACH BLOWER ASSEMBLY THAT IS SUSPENDED FROM THE ROOF TRUSSES

WILL BE REUSED TO THE GREATEST EXTENT POSSIBLE. USE CARE SO THAT NO DAMAGED IS DONE TO THE REMAINING

SYSTEM COMPONENTS AND FRAMEWORK.

6. THE CONTRACTOR WILL ENSURE THAT DURING CONSTRUCTION ANY WALL OPENINGS DUE TO DEMOLITION ARE COVERED

AND SECURED WITH TEMPORARY COVERS TO PROTECT AGAINST INTRUSION AND INCLEMENT WEATHER.

7. THE CONTRACTOR SHALL DEMOLITION THE WELDING TABLE SINGLE EXHAUSTER, DUCTWORK AND ASSOCIATED SUPPORT

FRAME. ONCE THE DUCTWORK IS REMOVED THE OPENING THROUGH THE WALL WILL BE COVERED AND SEALED USING 16

GAUGE SHEETMETAL, RIVETS AND APPROVED SEALANT TO ENSURE A SECURE WATER TIGHT COVER.

8. THE CONTRACTOR SHALL TRANSPORT AND DISPOSE OF CONSTRUCTION WASTE AND DEBRIS TO AN OFF-SITE SOLID

WASTE COLLECTION CENTER THAT HAS BEEN PERMITTED, BY THE JURISDICTION HAVING AUTHORITY TO ACCEPT AND
