This guide treats federal government contracting systematically, from market entry through dispute resolution and compliance. Part one covers the regulatory architecture, the authority of contracting officers, and the contract types that allocate risk. Part two covers acquisition methods: sealed bidding, negotiated procurement, commercial item and simplified acquisition procedures, evaluation factors, competitive range determinations, and discussions. Part three covers the small business programs, size standards, affiliation rules, and the limitations on subcontracting that make set-aside eligibility contestable. Part four covers bid protests in all three forums with the timeliness rules and the automatic stay that drive strategy. Part five covers performance — the changes clause, constructive changes, delay and disruption, requests for equitable adjustment, certified claims under the Contract Disputes Act, payment, and appeals. Part six covers terminations for convenience and for default, including conversion. Part seven covers False Claims Act exposure, the criminal statutes that parallel it, suspension and debarment, and organizational conflicts of interest. Tables, worked examples, and cross-references appear throughout.
