BONDING AND SURETY

CONSTRUCTION SURETY BONDS EXPLAINED.

QUICK ANSWER

Three bond types cover commercial work. A bid bond guarantees you'll sign the contract at your bid price and typically runs 5 to 10 percent of the bid amount. A performance bond guarantees you finish the job and a payment bond guarantees your suppliers and sub-subcontractors get paid, both typically written at 100 percent of contract value. How much bonded work you can carry at once is set by your working capital, not by how well you know your agent.

Most subcontractors treat bonding as a phone call to an agent. The surety treats it as an underwriting decision off your balance sheet. The single job limit and the aggregate limit both come out of working capital and equity, so the number you can carry is set months before you ask for a bond. That's why the answer at bid time is rarely negotiable. If you want more capacity next year, the work is keeping profit in the company this year and reporting it in a format the underwriter trusts.

THE DEFINITION

WHAT IT MEANS.

A surety bond is a guarantee from a third party that you'll finish the contract and pay your suppliers, and that the surety will cover the owner's loss if you don't.

Bonding requirements are a fact of life in commercial construction, and they get stricter on public projects and on larger private commercial work. Most subcontractors know they need bonds, and far fewer can say what each type covers, what it costs the business, or how their bonding capacity caps the volume of work they can take on.

The three types do different jobs and get issued at different points in the project. The capacity number sitting behind all of them is a balance sheet calculation, which means it responds to how you run the company and not to how badly you want the job.

WHAT WE SEE IN THIS BUSINESS

WHERE BONDING COSTS YOU WORK.

01

You're losing work because you can't get bonded

A GC requires a performance and payment bond on a project you want to win. You call your agent and find out that either you have no bonding program established or your aggregate capacity is already maxed out. The opportunity goes to a bonded competitor. Most subcontractors never build the bonding program ahead of time, so they find the limit at the worst possible moment.

02

You don't know what your aggregate bonding limit is

Your surety sets a single job limit and an aggregate bonded work limit, which is the most total value of bonded contracts you can have outstanding at one time. Most subcontractors can't state either number until they sit down to apply for a specific bond. By then there's no time left to improve the financial ratios that drive both limits.

03

Your financials aren't formatted for surety review

Sureties evaluate working capital, current ratio, equity position, the WIP schedule, and backlog. Most subcontractors send their surety a tax return or an informally assembled financial statement instead of the construction specific package a surety needs to judge capacity correctly. The underwriter then fills the holes with caution, and caution comes back as a lower limit.

THE ARITHMETIC

WHAT IT LOOKS LIKE IN DOLLARS.

The capacity math

Sureties use working capital as the primary driver, typically allowing $10 to $15 of aggregate bonded work per $1 of working capital. A contractor with $500K of working capital typically supports $5M to $7.5M in aggregate bonded work. Growing the bonding program means growing working capital, which means keeping earnings in the business instead of distributing them.

HOW SPM FIXES IT

WHAT WE CHANGE.

The three bond types every subcontractor needs to know

A bid bond guarantees you'll execute the contract at your bid price if you're selected, and it typically runs 5 to 10 percent of the bid amount. A performance bond guarantees you'll complete the project according to the contract terms, and a payment bond guarantees you'll pay your suppliers and sub-subcontractors, both typically written at 100 percent of contract value. Performance and payment bonds are almost always issued together, while bid bonds are issued separately at bid time.

Working capital managed with the bonding target in view

Because working capital is the primary driver of capacity, the bonding program grows only when the balance sheet grows. SPM manages working capital with bonding capacity goals in view for every client, so the distribution decision in a good year gets weighed against the capacity you want next year. Retained earnings are the only source of new capacity, and that makes capacity a decision rather than an accident.

Bonding ready financial reporting, kept current year round

SPM keeps the financial package a surety needs current all year: clean financial statements, a monthly WIP schedule reconciled to the balance sheet, an AR aging, and a backlog summary. When a bonding application or a renewal calls for financial documentation, it goes out immediately instead of starting a scramble. Underwriters price certainty, and a package that comes in complete and on time is worth capacity on its own.

COMMON QUESTIONS

FREQUENTLY ASKED.

Bond premiums for performance and payment bonds typically run 0.5 to 3 percent of the bond amount, depending on your financial strength, your bonding history, and how the surety reads the project risk. A contractor with clean financials, strong working capital, and an established surety relationship typically pays 0.5 to 1.5 percent. A contractor with weaker financials or a shorter track record pays 2 to 3 percent.
Not always. Bonds on private commercial projects are at the GC's or the owner's discretion. Public work at the federal, state, and municipal level typically requires bonds by law, the Miller Act at the federal level and state equivalents below it, and large private owners in institutional, healthcare, and higher education work often require bonds anyway. Settle the bonding requirement before you bid rather than after you win.
