Description

Site Visit is scheduled for 8 June at 1:00PM (Local Time). Building 10571 is a one-story, 68986 square feet (SF) building framed from steel and cast concrete (beams and columns with CMU infill). The building was originally constructed in the early 1940s and is a historic property. The main open space is 200-ft by 229 ft with a high barrel roof section that?s approximately 50,000 SF. Additionally, there are three (3) low slope roof lean-to sections. The North lean-to section is approximately 36-ft by 268-ft, with the South lean-to section at approximately 36-ft by 229-ft. The West lean-to section is approximately 36-ft by 180-ft. This Design-Build project will remove the existing built-up roof (BUR) from both barrel center section and the three (3) lower roof lean-to sections down to the existing structural decking. New 3-ply SBS-Modified BUR roof assembly with granular cap sheet on the barrel roof section shall be installed and the three (3) lower roof lean-to sections shall be replaced with new 90-mil Ethylene Propylene Diene Monomer (EPDM) roof assemblies. All roofing assemblies shall be fully adhered. Replace existing roof drains, flashings, vent pipe flashing, cover board, insulation, vapor barrier, cant strips, metal copings and trim with new.
