The General Services Administration (GSA) is seeking to lease 97,256 to 99,000 square feet of contiguous office and related space in Concord, Massachusetts, and the surrounding area, with a specific delineated boundary provided. The lease term is 15 years firm, and the space must provide a "line of sight" from the rooftop to Wachusett Mountain Tower, as determined by a field test. The offered space must meet government standards for fire safety, accessibility, seismic, and sustainability, and cannot be located in a 1% or 0.2% annual-chance floodplain. A fully serviced lease is required, and the government is considering alternative space if economically advantageous compared to its current expiring lease. No budget amount or submission timeline is specified.
