Ground-Up Construction Surety Bonds: What Contractors and Developers Need to Know
Ground-Up Construction Surety Bonds: What Contractors and Developers Need to Know
Ground-up construction surety bonds are three-party guarantees that protect project owners when a contractor takes a brand-new build from dirt to finished structure. They typically include bid bonds, performance bonds, and payment bonds — and on most public projects (and a growing number of private ones), you can't break ground without them. Premiums usually run 0.5% to 3% of the contract price, and self-quoting MGAs like Bond Exchange and Propeller now issue many of these bonds in minutes.
What Is a Ground-Up Construction Surety Bond?
A ground-up construction surety bond is a guarantee issued by a surety company that backs a contractor's promise to complete a new-build project according to the contract terms. "Ground-up" simply means the project starts from bare land — excavation, foundation, framing, and finish — rather than a renovation or tenant build-out.
Every construction bond involves three parties:
- Principal — the contractor or developer who buys the bond and is obligated to perform the work.
- Obligee — the project owner (public agency, private developer, or lender) who requires the bond and is protected by it.
- Surety — the insurance carrier that guarantees the contractor's performance and pays the obligee if the principal defaults.
If the contractor fails to perform — walks off the job, goes bankrupt, or skips paying subs and suppliers — the surety steps in to either finish the project, bring in a replacement contractor, or pay damages up to the bond amount. Unlike traditional insurance, surety bonds are a form of credit: the contractor ultimately reimburses the surety for any losses.
When Are Ground-Up Construction Bonds Required?
Bonding requirements vary by project type, owner, and contract size. Here's when you'll almost always need them:
- Federal projects over $150,000 — The Miller Act requires performance and payment bonds on almost every federal construction contract over this threshold.
- State and municipal "Little Miller Act" projects — Nearly every state has its own version of the Miller Act for public works, typically kicking in between $25,000 and $150,000.
- Private projects with lender or owner requirements — Many banks and commercial developers now require bonding on larger private builds to protect their capital.
- Subcontractor packages on large builds — General contractors often require their subs to post bonds on trades that carry significant delivery risk (structural, mechanical, electrical).
The Four Key Bonds on a Ground-Up Project
Most ground-up construction projects involve a stack of bonds, each protecting a different phase or party. Here's how they fit together:
Bid Bond Pre-Award
Bid bonds guarantee that if a contractor wins a bid, they'll actually sign the contract and post the required performance and payment bonds. If the contractor walks away after winning, the surety pays the difference between their bid and the next lowest bidder — up to the bond amount. Bid bonds are typically 5% to 10% of the bid price, and most carriers issue them at no cost when you commit to the final bonds.
Performance Bond During Build
Performance bonds guarantee that the contractor will complete the project according to the contract — on time, on spec, and on budget. If the contractor defaults, the surety must either arrange completion by another qualified contractor, pay the owner to finish the work, or pay damages. The bond is typically issued at 100% of the contract price.
Payment Bond During Build
Payment bonds guarantee that the contractor will pay all subcontractors, laborers, and material suppliers. They protect both the owner (from mechanic's liens) and the downstream trades (who have a direct claim against the bond if they're not paid). Payment bonds are almost always paired with performance bonds on public work and are typically also 100% of the contract price.
Maintenance / Warranty Bond Post-Completion
Maintenance bonds (sometimes called warranty bonds) cover defects in workmanship or materials that show up after the project is finished — typically for a period of 1 to 3 years. Many performance bonds roll into a built-in maintenance period, but larger public projects often require a separate, standalone maintenance bond.
How Much Do Construction Bonds Cost?
Surety bond premiums for ground-up construction projects depend heavily on the contractor's financial strength, experience, and project size. In general:
- Standard-market rates range from 0.5% to 1.5% of the contract price for qualified contractors with strong financials.
- Mid-range contractors typically pay 1.5% to 2.5%, depending on credit and past performance.
- Non-standard or SBA-backed programs can run 2.5% to 3%+ for newer contractors or those with credit challenges.
On a $1,000,000 ground-up commercial build, a qualified contractor might pay $7,500-$15,000 in total bond premium for combined performance and payment bonds. Larger, more complex, or higher-risk projects — such as multi-phase developments or projects with aggressive timelines — tend to sit at the upper end of the range.
Underwriters look at the "Three C's":
- Capacity — can you deliver the work? (experience, equipment, project backlog)
- Capital — is the business financially healthy? (working capital, net worth, debt)
- Character — will you do the right thing? (personal credit, reputation, references)
How to Get a Ground-Up Construction Surety Bond
Get your financial package together. Sureties will want current and prior-year business financial statements (preferably CPA-reviewed or audited for larger bonds), a work-in-progress (WIP) schedule, personal financial statements from all owners, and bank and trade references.
Choose the right surety market. Small projects (under $500k) can often be placed through a self-quoting MGA portal. Larger or more complex jobs usually require a traditional surety relationship with a dedicated underwriter.
Submit the bond application. Your agent will forward your financials, project details, and the bid documents or contract to the underwriter. For public bids, you'll often need a bid bond turned around within 24-48 hours.
Receive your single or aggregate limits. The surety will establish two caps — a single-job limit (the largest project they'll bond) and an aggregate program limit (the total backlog they'll support at once).
Sign the indemnity agreement. All owners — and often their spouses — sign a General Indemnity Agreement (GIA) pledging to reimburse the surety for any losses. This is a hard requirement in the construction bond market.
Pay premium and receive the bond. Once bound, you receive an original executed bond to file with the obligee (owner or public agency) before work can begin.

Why Bonding Capacity Matters More Than Premium
A common mistake for newer contractors is chasing the lowest bond rate. The bigger question isn't "what's my rate?" — it's "what's my capacity?"
Your single-job limit and aggregate limit determine the largest project you can chase and the total backlog you can carry. A surety that writes you at a slightly higher rate but gives you a bigger program is usually worth more to your business than a cheaper carrier that limits your backlog.
Strong bonding capacity is a competitive weapon on public bids — it lets you bid larger jobs, run more simultaneous projects, and win work that less-bonded competitors can't touch.

Frequently Asked Questions
What's the difference between a ground-up construction bond and a regular contract bond?
"Ground-up" refers to the project type — a new build from bare land — rather than a specific bond type. The bonds themselves (bid, performance, payment, maintenance) are the same contract surety products used on renovations and tenant improvements. Ground-up projects usually carry more risk because they involve longer schedules, more trades, and more exposure to weather, supply chain, and permitting issues, so underwriters scrutinize them more closely.
Can a new contractor get bonded for ground-up construction?
Yes, but with smaller limits to start. New contractors usually begin with SBA-backed programs or emerging contractor programs through carriers like Travelers, CNA, and Merchants Bonding. You'll likely be limited to smaller projects ($250k-$500k single limits) until you build a track record of completed jobs and stronger financials.
Do I need bonds on private commercial construction projects?
Not always, but increasingly yes. Many commercial lenders and developers require bonding on private ground-up projects over a certain contract size to protect their capital. Even when not contractually required, offering to post a performance bond can be a competitive advantage when bidding against uninsured competitors.
How long does it take to get a construction surety bond?
For self-quoting MGA portals on smaller jobs, you can often get a bid or performance bond issued the same day — sometimes in under an hour. For larger programs through a traditional surety, initial account setup takes 1-3 weeks (financials, indemnity, underwriter review), but once your program is in place, individual bonds typically issue in 24-48 hours.
What happens if a contractor defaults on a bonded project?
The surety investigates the claim and then chooses one of three remedies: (1) tender a replacement contractor to finish the work, (2) finance the original contractor to complete the job, or (3) pay the owner the cost of completion up to the bond amount. The surety then pursues the contractor and all indemnitors personally to recover those losses under the General Indemnity Agreement.
Do owners and spouses really have to sign personal indemnity?
On contract surety, almost always — yes. Sureties require personal indemnity from all 5%+ owners and typically their spouses as well (to reach marital assets in community property and tenancy-by-the-entirety states). Some large, publicly-traded contractors can negotiate corporate-only indemnity, but that's the exception, not the rule.
What documents do I need to apply for a construction bond program?
For a typical contractor surety program, expect to provide: (1) two to three years of business financial statements (CPA-reviewed or audited for larger programs), (2) a current work-in-progress (WIP) schedule, (3) personal financial statements from all owners, (4) a signed general indemnity agreement, (5) bank and trade references, and (6) the contract documents or bid form for the specific project.
