Where general contractors source subcontractors
Most GCs keep a bid list for each trade and add to it when they need more coverage or a specialist. New names usually come from a handful of places:
| Channel | How it works | What helps you |
|---|---|---|
| Bid management platforms | GCs send invitations through platforms such as BuildingConnected, PlanHub, ConstructConnect or the bid tools in their project management software. | A complete profile with accurate trades, CSI divisions and service area. |
| Existing bid lists | Subs who bid well and perform get invited again. | Responsive bidding, clear scopes and a good track record. |
| Referrals | Superintendents, other subs and suppliers recommend people they trust. | A website and capability statement that back up the referral. |
| Prequalification | Many GCs require a prequal form before a first invitation. | Licensing, insurance, safety and financial details ready to go. |
| Search and LinkedIn | Estimators search for a specialty trade in a specific area when their list is thin. | Trade and location pages that clearly match the search. |
| Diversity outreach | Public and private projects with participation goals look for certified firms. | Current certifications, listed prominently. |
Prequalification is the gate
Prequalification forms vary, but they commonly ask about:
- Company history, ownership and years in business
- Licenses and the trades you self-perform
- Insurance coverage and bonding capacity
- Safety program and safety statistics
- Recent comparable projects and references
- Financial information for larger contracts
Keep a folder with these answers up to date. Responding to a prequal request the same day makes a strong first impression.

Certifications and public work
If your firm holds a minority-, women-, veteran- or disadvantaged-business certification, list it prominently and keep it current. Public owners and GCs pursuing participation goals often search certification directories maintained by the certifying agencies. For federal work, a registration in SAM.gov with a Unique Entity ID is required.
