The U.S. Government seeks competitive lease proposals for office space between 3,965 and 4,163 ABOA square feet in the West Boston/East Worcester, Massachusetts area, within a specifically delineated boundary. The lease term is for 17 years, with 15 years firm, and the government provides a tenant improvement allowance of $66.04 per ABOA SF and building specific amortized capital of $12.00 per ABOA SF. The space must be second-generation, requiring only minimal construction and reconfiguration to meet a specific layout, and the offeror's ability to meet a strict post-award schedule is a critical factor for technical acceptability. The procurement will result in a lease award to the lowest-priced, technically acceptable offer.
