The lease term is for 17 years, with 15 years firm, and includes a tenant improvement allowance of $66.04 per ABOA SF and building specific amortized capital of $12.00 per ABOA SF. The Government requires second-generation space needing minimal construction and places significant emphasis on an offeror's proven ability to meet a strict post-award schedule, requiring a detailed feasibility narrative and evidence of contractor capability for technical acceptability. Award will be made to the lowest-priced, technically acceptable offer, and the space must comply with all federal, state, and local requirements.
