Federal agencies report every prime contract they sign to the government's register of federal awards: the recipient and its address, the awarding agency and office, the amount obligated, the dates, the industry and product or service codes, where the work is done and how the contract was competed. Contracts to small businesses are marked as such in the same record.
Every figure on this page is taken from the contract's own federal record, linked beside it, as it stood when the page was built. The amount obligated can grow later if the agency adds funding or exercises options on the same contract; the value with all options, where shown, is the most the record says it could reach.
