The project also includes replacing heat exchangers and hydronic pumps, installing new area drains, and reinforcing the structural integrity of existing concrete floor slabs through structural reinforcement, concrete coring, and shaft wall construction. Additionally, the scope covers lighting upgrades, selective demolition of existing architectural features, and repairs to fireproofing, plaster, gypsum board, and acoustic ceiling panels. The project is managed by the Airport Development organization in Minnesota, with a contract value estimated between five and fifteen million dollars, and responses are due by May 13, 2025.
