The U.S. Fish and Wildlife Service requires construction services to replace approximately 2,863 square feet of the existing built-up roof on the historic 1937 CCC-constructed Biology Building at Bitter Lake National Wildlife Refuge in Roswell, New Mexico. The project involves installing a new fleece back membrane roofing system with all required flashings, terminations, penetrations, and accessories, while maintaining the historic integrity of the structure. The contractor must furnish all labor, materials, equipment, transportation, and supervision. The government intends to award a single firm-fixed-price contract based on best value, considering price, technical approach, and past performance.
