Subcontract work reported by primes
Prime contractors reported 8 subcontracts to it worth about $4.6 million in the last five years, according to USAspending.gov. Primes only have to report subcontracts of $40,000 or more (since October 1, 2025; $30,000 before that), so smaller jobs are missing. Amounts are net of any cuts primes reported. None of this is in the prime contract figures.
