Discover where and how to find construction bid opportunities. Learn 15 effective strategies for finding public works bids, private projects, and subcontractor opportunities to grow your construction business.
Finding Construction Projects: The Complete Guide
Quick Answer
The best ways to find construction projects in 2025 are: (1) Bid aggregation platforms like ConstructionBids.ai for comprehensive coverage, (2) SAM.gov for federal opportunities, (3) Direct agency relationships with local governments, and (4) General contractor networks for subcontractor work. Most successful contractors use 3-4 sources simultaneously.
Finding enough bid opportunities is one of the biggest challenges for construction contractors. Whether you're a general contractor looking for public works projects or a specialty subcontractor seeking private commercial work, having a consistent pipeline of bidding opportunities is essential for business growth.
This guide covers 15 proven methods for finding construction projects, organized by source type. We'll examine both free and paid options, with practical advice on maximizing each approach.
| Source Type | Cost | Volume | Competition | Best For |
|---|---|---|---|---|
| Bid Aggregator Platforms | $99-500/mo | High | Medium | All contractors |
| SAM.gov (Federal) | Free | Medium | High | Federal contractors |
| Local Agency Websites | Free | Low | Medium | Local contractors |
| GC Relationships | Free | Variable | Low | Subcontractors |
| Plan Rooms | $50-300/mo | Medium | Medium | GCs and subs |
Method 1-5: Government Bid Sources
Government construction represents roughly 20% of all U.S. construction spending—over $350 billion annually. These publicly-funded projects must follow transparent bidding processes, making them accessible to qualified contractors.
SAM.gov (System for Award Management) is the official source for federal contract opportunities. All federal agencies must post solicitations here, making it the definitive resource for federal construction work.
Advantages
- • Completely free to use
- • Direct from source (no intermediary)
- • Includes contract award history
- • Email alerts available
Limitations
- • Federal opportunities only
- • Interface can be clunky
- • High competition on many bids
- • Requires SAM registration to bid
Pro Tip: Set up saved searches for NAICS codes 236220 (Commercial Building) and 237310 (Highway/Street) to receive automatic email notifications.
Every state operates its own procurement website for state-funded construction projects. These include highway departments (DOTs), university systems, state buildings, and infrastructure projects.
California
Cal eProcure, Caltrans
Texas
ESBD, TxDOT
Florida
MyFloridaMarketPlace
Pro Tip: Register with your state's vendor database to receive automatic notifications. Most states require vendor registration before you can bid anyway.
Local municipalities post bids on their own websites or through platforms like PlanetBids, CivCast, or BidSync. This includes city infrastructure, public buildings, parks, and utilities.
- Large cities: Often have dedicated procurement departments with robust online systems
- Small cities/counties: May post bids on general website or local newspapers
- Special districts: Water districts, school districts, and transit authorities often have separate procurement
Pro Tip: Make a list of the 20-30 agencies in your service area and check their websites weekly, or use an aggregator to monitor them automatically.
Many states require public agencies to publish bid notices in "newspapers of record" or legal publications. While declining in importance, this remains a legal requirement in some jurisdictions.
- • Daily Journal (California)
- • The Bond Buyer (national)
- • Local daily newspapers (varies by state)
Pro Tip: Legal notices are often published 2-3 weeks before bid dates, giving you less time than electronic postings. Use this as a backup, not primary source.
Attending pre-bid meetings and mandatory site walks helps you find opportunities and understand project scope. It's also an excellent networking opportunity to meet GCs and other subs.
- • Learn about upcoming projects before formal solicitation
- • Get inside information on agency priorities
- • Meet procurement officers and project managers
- • Identify teaming opportunities with other contractors
Pro Tip: Even if you don't bid, attending pre-bids builds relationships with agency staff who may contact you for future opportunities.
Method 6-8: Private Project Sources
Private construction (commercial, industrial, residential) represents about 80% of all construction spending. These projects don't have the same public posting requirements, making them harder to find but often less competitive.
Plan rooms (also called builders exchanges) host project documents from GCs seeking subcontractor bids. These are particularly valuable for private commercial projects that aren't publicly advertised.
Regional Plan Rooms
- • Local builders exchanges (AGC chapters)
- • Regional contractor associations
- • Trade-specific plan rooms
Online Plan Rooms
- • ConstructConnect
- • iSqFt (now ConstructConnect)
- • BuildingConnected
Tracking commercial real estate news helps you identify projects before they go out to bid. Development announcements, permit filings, and land sales signal upcoming construction opportunities.
- • CoStar/LoopNet: Commercial property transactions
- • Local business journals: Development announcements
- • Building permit databases: City/county websites
- • Planning commission agendas: Project approvals
Pro Tip: When you see a development announcement, reach out to the developer or their known GC before formal bidding begins. Early relationships win work.
Building relationships with property developers, owners, and facility managers can lead to negotiated work without competitive bidding. This is particularly effective for specialty contractors and those with niche expertise.
- Target accounts: Identify 10-20 developers/owners in your market
- Marketing: Send capability statements, request meetings
- Follow up: Stay in touch quarterly even without immediate work
- Deliver: Great work on initial projects leads to repeat business
Method 9-10: Online Bid Platforms
Bid aggregation platforms compile opportunities from thousands of sources into searchable databases with automated alerts. For most contractors, these offer the best time-to-opportunity ratio.
Bid aggregators like ConstructionBids.ai, BidNet, and DemandStar automatically monitor thousands of government agencies and private sources, delivering matching opportunities to your inbox.

Method 11-12: Networking & Relationships
Joining contractor associations provides access to project leads, plan rooms, and networking events where you meet GCs, owners, and fellow contractors.
General Associations
- • AGC (Associated General Contractors)
- • ABC (Associated Builders & Contractors)
- • Local builders exchanges
Trade-Specific
- • NECA (electrical)
- • SMACNA (sheet metal)
- • MCAA (mechanical)
Design professionals often know about projects before contractors. A/E firms may recommend contractors to owners or provide early notice of upcoming bid opportunities.
- • Attend AIA (architects) and ACEC (engineers) events
- • Offer value: help with constructability reviews, budgeting
- • Stay in touch with firms you've worked with successfully
- • Some design-build opportunities come through A/E relationships
Method 13-14: Subcontractor Opportunities
Getting on GC bid lists is essential for subcontractors. When GCs pursue projects, they solicit bids from their preferred subcontractor roster.
Online platforms connect subcontractors directly with GCs seeking bids. These provide access to private bid invitations you wouldn't see otherwise.
- BuildingConnected: GC-sub collaboration platform (Autodesk)
- Procore Bid Management: If GCs use Procore, you'll get ITBs through their system
- ConstructConnect Network: Plan room + subcontractor matching
Pro Tip: Complete your profile thoroughly on these platforms. GCs filter by certification, location, and trade—incomplete profiles get skipped.
Method 15: Proactive Business Development
Don't just wait for bid invitations—actively pursue work through direct outreach, marketing, and relationship building. This is especially valuable for negotiated work without formal bidding.
Outreach Tactics
- • Cold calling property managers and facility directors
- • Capability statement mailings to target accounts
- • LinkedIn outreach to decision-makers
- • Lunch-and-learns with potential clients
Marketing Channels
- • Company website with project portfolio
- • Google Business Profile (local SEO)
- • Industry directory listings
- • Trade show participation
Qualifying Bid Opportunities
Finding opportunities is only half the battle—you need to qualify them to avoid wasting time on bids you can't win or shouldn't pursue. Use this checklist:
Can we perform the work?
Do we have the capability, equipment, and workforce?
Can we bond it?
Is the project within our bonding capacity?
Is the timeline realistic?
Do we have enough time to bid? To perform the work?
Is it profitable at market rates?
Given our costs, can we be competitive and profitable?
Do we have a realistic chance?
Is there an incumbent? Are requirements tailored to a competitor?
The 80/20 Rule of Bidding
Successful contractors don't bid on everything—they bid selectively on opportunities where they have a realistic chance of winning. Most contractors find that 80% of their wins come from 20% of their bids. Focus your energy on high-probability opportunities.
Tracking & Organization Systems
With opportunities coming from multiple sources, you need a system to track, prioritize, and follow up. Here are proven approaches:
For contractors bidding on 5-15 projects/month:
- • Google Sheets or Excel tracker
- • Columns: Project, Owner, Due Date, Status, Notes
- • Color-code by priority/status
- • Calendar alerts for deadlines
For contractors with dedicated BD staff:
- • Salesforce, HubSpot, or Pipedrive
- • Full pipeline tracking and forecasting
- • Integration with bid platforms
- • Team collaboration and handoffs
Frequently Asked Questions
How many bid sources should I use?
Most successful contractors use 3-5 primary sources. A typical mix might be: (1) a bid aggregator platform for comprehensive coverage, (2) SAM.gov for federal work, (3) 2-3 local agency direct subscriptions, and (4) GC relationships for subcontract work. Using too few sources means missing opportunities; using too many becomes unmanageable.
How much should I spend on bid finding services?
Budget 1-2% of your target annual revenue for bid finding and business development. For a contractor targeting $5M in annual revenue, that's $50,000-$100,000/year for all BD activities including software subscriptions ($1,200-$6,000/year), association dues, marketing, and BD staff time. The ROI is typically 10-50x if used effectively.
How do I find private commercial construction bids?
Private commercial bids typically come through: (1) GC bid invitations if you're a subcontractor, (2) plan rooms and builder exchanges, (3) direct developer relationships, (4) project databases like Dodge that track planning-stage projects, and (5) bid aggregators like ConstructionBids.ai that include private opportunities. Unlike government bids, private work often requires relationship-building before receiving invitations.
What's the best free way to find construction bids?
The best free methods are: (1) SAM.gov for federal opportunities, (2) direct subscription to local government agency bid notifications, (3) Google Alerts for "construction bid + [your city]", and (4) networking through free industry events. While effective, free methods require significantly more time than paid platforms and typically miss many opportunities. Most serious contractors find the $99-300/month for aggregator services pays for itself many times over.
How do I get on more GC bid lists as a subcontractor?
To get on GC bid lists: (1) Identify GCs winning work in your trade and region, (2) Complete their prequalification process (safety program, insurance, references), (3) Follow up with estimating managers personally, (4) Join platforms like BuildingConnected where GCs post ITBs, (5) Attend industry events and pre-bid meetings to network, and (6) Deliver great work when you get opportunities—reputation spreads quickly.
How early can I learn about upcoming projects?
Project intelligence services like Dodge Construction Network track projects from early planning stages, sometimes 12-18 months before bidding. Building permits and planning commission agendas provide 3-6 month advance notice. Most bid aggregators show opportunities 2-4 weeks before deadlines. For the earliest notice, combine planning-stage intelligence with relationship building so owners and architects contact you directly.
Should I bid on every opportunity I find?
No. Selective bidding is more profitable than volume bidding. Qualify each opportunity against criteria: Can you perform it? Can you bond it? Is the timeline realistic? Do you have a reasonable chance of winning? Most successful contractors have a 15-25% win rate on bids they pursue—if your rate is much lower, you're probably bidding on too many marginal opportunities.
How do I find small construction jobs under $50,000?
Small jobs often don't go through formal bidding. Find them through: (1) Property management company relationships (repairs, tenant improvements), (2) Facility manager direct contacts, (3) Local handyman/contractor referral networks, (4) Google Business Profile optimization for local searches, (5) Small purchase programs at government agencies (often simplified process under $25K-$50K thresholds), and (6) Word-of-mouth from satisfied customers.
Conclusion: Build Your Opportunity Pipeline
Finding construction projects requires a multi-channel approach. No single source covers all opportunities, but using 3-5 complementary methods ensures a steady pipeline of bidding opportunities without overwhelming your team.
For most contractors, the highest-impact first step is subscribing to a bid aggregation platform. This provides immediate, comprehensive coverage while you build out other sources like GC relationships and direct agency contacts.
