Sources, credits, and required notices

Data sources & legal.

NextGig organizes public records so contractors can check potential work in one place. The information itself comes from government sources. Always confirm details on the official record.

What the listings are

Federal notices come from SAM.gov contract opportunities. Local open bids come from San Francisco’s Open Bid Opportunities feed, the City of Chicago’s Solicitation Search (city purchasing solicitations, including CTA postings), and Washington’s WEBS public bid calendar (Washington state agency notices, plus a few other public bodies that post there), and California Caltrans’s public contracting list (construction and service solicitations only, not the full state CSCR board). Construction signals come from city building and trade permit data. Permits are not invitations to bid, and a contractor may already be appointed. NextGig does not sell exclusive access or guarantee any contract.

Current searchable trades are plumbing, HVAC, electrical, roofing, concrete and masonry, carpentry and framing, fire protection and sprinklers, painting and coatings, flooring, drywall and interiors, landscaping and site work, demolition, and general contractor / building construction. Permit coverage is limited to Seattle, Chicago, and San Francisco city limits. SAM.gov coverage is nationwide but thin for these trades, and it is not every federal purchase. Local government bids are limited to San Francisco and City of Chicago purchasing and Washington state agency notices on WEBS, plus California Caltrans construction/service bids. Cal eProcure / CSCR is not ingested because unattended public access was blocked. WEBS is not every Washington city, county, or school district, and Seattle city purchasing is not included. Sound Transit, Cook County, suburbs, Illinois BidBuy, and other state and local bid feeds are not included. Most WEBS notices name no worksite, so they are labeled statewide and left off the map. Caltrans single-county listings use approximate county areas, never agency office locations; multi-county or unspecified listings are distance-unconfirmed and left off the map.
