Roof Repair on Communications Building 405

The project consists of one line item. Line item one: The contractor shall furnish all supervision, labor, materials, tools, equipment, apparatus, and transportation required to demolish and remove the existing roofing systems on a 6,250 SF portion of Building 405, Communications. All roofing shall be removed and replaced except that of the latest building addition which was completed in 2011. The roofing to be replaced is a combination of built up roofing with gravel ballast and fully adhered elastomeric roofing system. That roofing, including the underlying insulation, must be removed and replaced with a fully adhered 0.060 EPDM single-ply reinforced membrane roof system with 2 layers of 2" polyisocyanurate tapered insulation and cover boards. Replace all roof penetrations (vents, stacks, pitch pockets, equipment supports, etc.). Provide additional new equipment supports for equipment on roof that does not have appropriate permanent supports, such as existing satellite dish. Remove unused equipment supports. Replace all roof flashing, coping, expansion joints and covers, drains, scuppers, gutters, and downspouts. Replace deteriorated roof decking as needed. Remove and reinstall existing lightning protection system. Due to the composition and ages of the existing roof systems, it is anticipated that asbestos is present in the flashing and will require abatement.
