Frequently Asked Questions
Do I need to pay for bid aggregation services or can I find everything free?
Technically all public bids are free to access on agency websites. However, manually checking hundreds of sites daily is impractical. Most contractors find that aggregation services ($99-$500/month) pay for themselves many times over by saving time and discovering opportunities they'd otherwise miss. If one additional project per year comes from the service, the ROI is massive.
Which bid sources are most important for small contractors?
Start local: Register on PlanetBids for your county and cities, join your local construction association, and get on prequalified lists for nearby agencies. Local government projects are often sized appropriately for small contractors ($50K-$500K) and don't require extensive bonding. As you grow, expand to state DOT and larger city projects.
How do I get invited to bid on private projects?
Private work is relationship-driven. Create a profile on BuildingConnected to receive invitations from GCs. Network at industry events to meet developers and owners. Ask current clients for referrals. Get on prequalified lists with major GCs in your area. Consistently deliver quality work - reputation is everything in private sector bidding.
Should subcontractors look for prime contracts or focus on subcontract opportunities?
Most trade contractors should pursue both. Prime directly on smaller government projects in your specialty (under $100K often doesn't require general contractor license). Subcontract on larger projects where a GC is required. This diversifies your pipeline and reduces dependence on any single GC relationship.
How far in advance are construction projects typically advertised?
Public bids: Usually 20-45 days before due date (sometimes longer for large projects). Private invitations: Often 2-4 weeks, sometimes shorter for fast-track work. Planning intelligence (Dodge, capital improvement plans): Can show projects 6-24 months before bidding. Early awareness allows you to build relationships and position yourself before formal bidding.
What information should I track in my bid search?
Use a CRM or spreadsheet to track: Project name, owner/agency, location, estimated value, scope summary, bid due date, prebid meeting dates, source where you found it, decision (bid/no-bid), and reason. This data helps you understand which sources produce the best opportunities and refine your search strategy over time.
Are there opportunities specifically for small or disadvantaged businesses?
Yes. Federal agencies have set-aside programs for small businesses (8(a), HUBZone, SDVOSB). Many state and local agencies have small business and DBE/MBE/WBE goals. Getting certified can open access to less competitive opportunities and help you meet participation requirements on larger projects. Contact your local SBA office or state certification program.
How many bid opportunities should I be tracking monthly?
This depends on your capacity and win rate. A typical formula: If you want to win 2-3 projects/month and your win rate is 20%, you need to bid 10-15 qualified opportunities. You might discover 30-50 potentially relevant projects but filter down to the best-fit opportunities. Quality beats quantity - focus on projects you can actually win.
Conclusion
Finding construction bid opportunities requires a systematic, multi-channel approach. While projects are advertised across hundreds of platforms, modern aggregation technology and strategic networking make it possible to efficiently discover qualified opportunities without full-time business development staff.
Start by establishing automated discovery through a bid aggregation platform. Register on key agency portals in your service area. Build relationships through industry associations and past client contact. Track your results to optimize which sources provide the best return on your time and investment. With this systematic approach, you'll build a consistent pipeline of opportunities matching your capabilities and capacity.
