OBrien Boiler Existing Stacks.pdf

This solicitation notice seeks proposals to replace existing roofing systems at the Leo O'Brien Federal Building in New York. The base bid work includes replacing approximately 17,225 square feet of roofing with a new fully adhered TPO membrane system comprising torch-down vapor barrier, extruded polystyrene insulation to a height of 4.5 inches, cover board, and 80-mil TPO membrane. It also requires fire-rated wood curbing, drain inserts and strainers, guardrails, a tie-off system, and lightning protection. The alternative bid differs only in specifying 6.5 inches of insulation and raised roof areas around four cell towers. The option work adds removing and replacing roof pavers and the narrow roof band at the 10th floor, replacing a door, and applying silicone coating to cooling tower walls. Proposers must provide warranties and one year after substantial completion perform an infrared scan of all roof areas to identify any issues. The General Services Administration seeks proposals for this work as a 100% total small business set-aside.
