The servicing housing office must follow Federal procurement or other Bureau-approved tribal procurement policy. Generally, your servicing housing office develops a "bid specification" or statement of work, which identifies the work to be performed. The appropriate contracting office uses the "bid specification" to provide information and invite bids on the project to interested parties. The contracting office selects the winning bidder after technical review of the bids by and written recommendation from the servicing housing office, and after determination that the bidder is qualified and capable of completing the project as advertised.
