Why bid Department of the Interior
Interior is one of the strongest federal homes for HUBZone and 8(a) set-asides — public-lands work tends to land in rural HUBZone-designated counties. Small construction firms and environmental consultancies have a real pipeline through BLM district offices and NPS regional procurement. Watch ID/IQ construction vehicles like NPS 'Park Construction' and USFWS regional SATOC pools — these run multi-million in annual task orders to small primes.
