Document Description
This project proposes to reroof the Chinese Exhibit Building (307-A-4-02-0-021) in Columbia State Historic Park to allow for the continued use of this historic building.
• Prior to contracted work to replace the roof, survey and assess for the presence of Asbestos Containing Materials in the roof substrates:
• Remove the existing roofing materials and install a thermoplastic polyolefin membrane to the roof structure;
• 2-ft above scupper level, install new 3-in. overflow pipes, penetrating the parapets at a nonconspicuous place;
• Use 3/8-in. all-thread anchors to mount wooden 2-ft x 4-ft boards on the vertical plane and top:
• Drill anchors into the brick masonry parapets at 24-in. on center and run vertical; and 24-in. on center at the top of the parapets, and fill holes with epoxy to secure the all-thread studs;
• Install new plywood sheathing and cover with thermoplastic polyolefin membrane, secured over the parapets with a vinyl-coated metal edge screwed into wood and/or masonry and sealed with epoxy;
• Fit and seal drain collars and leaders on existing roof drains;
• Use hot-air welding and caulking to seal openings; and
• Replace leaders, scuppers, drainpipes, and boots where necessary to ensure water moves away from buildings.
