STATEMENT OF WORK

PROJECT NO. AFID 1054767

REPAIR ROOF- (TEMP), DOCK 7, BLDG 970

1. GENERAL

1.1 The existing roofing system on the upper roof of Building 970 is a 60 mil EPDM membrane fully adhered to a 2” isocynurate insulation board that is over a 3” isocynurate insulation board that is a filler in the pans of an existing standing seam metal roof; over batt insulation that is on a structural steel deck. Both layers of insulation board have screw fasteners that penetrate through the bottom structural steel deck. About two thirds of the north portion of the roofing was torn and blown off over the east end of the building. Most of the insulation board is still intact but, a small amount of the insulation board was pulled up and removed with the roofing membrane tear off. All torn off roofing membrane with some insulation board and fascia wood/metal blew over the east wall, was cut off and hauled away. There are other areas on the upper roof that existing EPDM membrane is loose but has not torn and blown away. If possible this could be reused with added surfaced mounted strip furring. Contractor shall retain the existing lightning protection system on the upper roof.

2.2. Contractor shall remove all damaged roof membrane, insulation board and perimeter wood/metal flashing as required that will not be retained.
