Frequently Asked Questions
What types of federal construction contracts are available (NAICS 23)?
Federal construction contracts (NAICS sector 23) span building construction, heavy civil engineering, and specialty trades. Major buyers include the Army Corps of Engineers, General Services Administration (GSA), Naval Facilities Engineering Command (NAVFAC), and the Department of Veterans Affairs. Contracts range from facility maintenance to large infrastructure projects.
How do I find federal contracting opportunities?
Federal contracting opportunities are posted on SAM.gov (System for Award Management). You can search by keyword, NAICS code, set-aside type, agency, and response deadline. FedOps aggregates and enriches SAM.gov data daily so you can filter and track opportunities in one place.
What is a set-aside in federal contracting?
A set-aside is a procurement reserved for a specific category of small business. Common set-asides include SDVOSB (Service-Disabled Veteran-Owned), 8(a), WOSB (Women-Owned), HUBZone, and Small Business. Only businesses that meet the eligibility requirements can bid on a set-aside contract.
How do I register to bid on federal contracts?
You must register your business in SAM.gov (sam.gov), which is free. You'll need a DUNS/UEI number, NAICS codes for your business, bank account information for electronic funds transfer, and applicable certifications (8(a), SDVOSB, WOSB, etc.) if bidding on set-asides. Registration is renewed annually.
