What is the best construction bidding site?

There is no single best site, because the work is spread across federal, state, and local sources. For federal work, start with SAM.gov. For state and local work, go straight to your state DOT portal, your state procurement system, and your local government bid boards, which are free. Paid aggregators like Dodge, ConstructConnect, BidNet Direct, and PlanHub are worth it once you are bidding enough volume that the time they save outweighs the subscription cost.

How do I find construction jobs to bid on for free?

Most government work is free to find. SAM.gov for federal, your state DOT and state procurement portals, and your local city, county, and school district bid pages all post opportunities at no cost. Free tiers on aggregators like DemandStar and Public Purchase can cover a single state or agency. You generally only pay when you want wider multi-state coverage or automated bid alerts.

Do I need a license to bid on public construction work?

In most cases yes. Public agencies typically require the appropriate contractor license for the work, and many require you to be prequalified or registered before you can bid. Requirements vary by state and by agency, so confirm the specific requirements with the awarding authority and your state licensing board before you bid.

Do I need a bond to bid on government construction jobs?

Almost always. Public projects usually require a bid bond just to submit, and the winning contractor must post performance and payment bonds before signing. Federal projects follow the Miller Act; state and local projects follow their state's Little Miller Act, each with its own dollar threshold.

How much does it cost to get bonded for a bid?

Bid bonds are typically issued at no direct premium as part of your bonding program. For performance and payment bonds, the cost generally runs a small percentage of the contract value for qualified contractors. Build that into your bid like any other cost of doing the work.

What is a surety bond?

A surety bond is a three-party agreement that guarantees you will do what you promised. You are the principal, the party requiring the bond is the obligee, and the surety company backs your promise. If you do not perform, the surety pays the obligee and then collects that money back from you. A surety bond is not insurance.

What is the purpose of a surety bond?

It protects the obligee, not you. The bond guarantees that you will finish the job, pay your subcontractors and suppliers, or follow the laws tied to your license. If you fall short, the obligee has financial recourse through the bond.

Who are the three parties to a surety bond?

The principal (you, the contractor or business that buys the bond), the obligee (the project owner, government agency, or general contractor that requires it), and the surety (the bond company that guarantees your performance and pays valid claims).

Is a surety bond insurance?

No. Insurance protects you against your own losses. A surety bond protects the other party against your failure to perform, and if the surety pays a claim, you reimburse it in full. Think of a bond as a line of credit backing your promise, not a policy that absorbs your loss.

What does a surety bond cost?

You pay a premium, not the full bond amount. License and permit bonds are often a flat annual premium in the low hundreds of dollars. Contract bonds (bid, performance, and payment) typically run about 1% to 3% of the contract value for contractors with solid financials. Your bond type, credit, experience, and financial strength drive the rate.

What credit score is needed for a surety bond?

There is no single cutoff. Many license and smaller commercial bonds approve quickly with credit in the 600s, and bad-credit bond programs exist below that at a higher rate. Larger contract bonds look at your full financial picture, not just your credit score. At Grit, our job is to find the path to yes.

What are the disadvantages of a surety bond?

The main one: it is not insurance. If a claim is paid, you pay it back. You also pay a premium each term, and qualifying for larger bonds means sharing financial information with the surety. The upside is that bonding unlocks bigger jobs and public work you could not bid otherwise.

Who needs a surety bond?

Contractors bidding public construction almost always need them. The federal Miller Act requires bonds on federal projects over $150,000, and every state has a Little Miller Act for state and local work. Many private owners require bonding on larger jobs, and most states require a license or permit bond to hold a contractor's license.

The short answer for Alabama

Public construction work in Alabama is posted in four places: ALDOT (Alabama Department of Transportation) for highway and civil work, STAARS Vendor Self Service (VSS) for state agency projects, your local city, county, and school district bid boards, and SAM.gov for federal work. Most are free to search. To win the work you will usually need a bond - Alabama requires a performance bond (100%) and payment bond (50%) on public works contracts over $100,000.

Finding public construction work in Alabama

Alabama state agency work: STAARS Vendor Self Service (VSS)

Go to: STAARS Vendor Self Service (VSS).

Alabama local government work: city, county, and school district bid boards

This is where most contractors should start. Cities, counties, school districts, and special districts build constantly and have to advertise it publicly. The jobs are smaller, the competition is thinner, and the bonding is more reachable for a growing company. Major Alabama bid boards:

Federal work in Alabama: SAM.gov

Every open federal construction contract is posted on SAM.gov, and it is free to search and register. You need an active registration and a Unique Entity ID before you can bid. Federal jobs over $150,000 require performance and payment bonds under the Miller Act - see our Miller Act guide.

The bond you need to bid public work in Alabama

Alabama requires a performance bond at 100% of the contract price and a payment bond at no less than 50% on public works contracts over $100,000 - a threshold raised from $50,000 effective September 1, 2023 (Ala. Code 39-1-1). Many local boards also require a 5% bid bond to submit. (Ala. Code § 39-1-1.) Below those points many jobs still require a bid bond just to submit. The bottom line: if you want public work in Alabama, you have to be bondable.

That is where contractors lose jobs to competitors who are no better at the work - the other bidder could produce the bond and they could not. It is usually more reachable than contractors assume. If you are not sure where your bonding stands, start with what a surety bond is, see how contractors qualify, or read the full national guide on how to find construction work to bid on.

Alabama certification programs

Alabama certifies firms for the federal DBE program through the Alabama Unified Certification Program (ALDOT). Federal DBE rules changed in late 2025 - confirm current status and eligibility before relying on it.
