Public works owners have one overriding concern: will the contractor finish the job for the agreed price and quality, no matter what happens on site or in the market. Performance security is how they sleep at night. Most agencies satisfy that need with surety bonds, but a subset use or accept a cash performance bond, a more literal form of security that puts actual money under the owner’s control. The form sounds simple. In practice, it touches procurement law, treasury management, contractor liquidity, and the fine print of contract default. Getting it wrong can lock up capital or leave an owner exposed when it matters most.
I have sat on both sides of the table: preparing bid packages for municipalities and negotiating bonding on the contractor’s behalf. The pattern is predictable. Cash looks clean until you chase the consequences. The right answer depends on project size, the local statute, and the contractor’s balance sheet.
What owners mean when they ask for “cash”
“Cash performance bond” is shorthand, and it takes three main shapes. The dominant versions are:
- A cash deposit placed with the owner or escrow agent in the required percentage of the contract price, held until completion or expiration of the defects period. An irrevocable letter of credit that functions like cash, callable on demand, usually issued by a bank rated A- or better, with terms matching the contract’s security clause.
Agencies also use time or savings deposits, treasury bills, or certificates of deposit assigned to the owner. The logic is the same. Unlike a surety bond, which is a third-party promise, a cash performance bond is liquid collateral immediately available to the owner on a claim. Many statutes treat letters of credit as “cash equivalents,” and procurement manuals lump them under the same heading.
Typical requirements sit at 100 percent of the contract price for federal and most state vertical construction, with some local agencies setting lower percentages for smaller jobs. The federal Miller Act mandates surety bonds for many federal contracts, but agencies can and do accept alternatives on qualifying smaller projects or where permitted by program rules. State “Little Miller Acts” often mirror that approach, while municipal purchasing codes can be more flexible. Always verify the governing statute before substituting surety with cash.
How performance security fits into the risk stack
On a public job, performance security is one pillar among several:
- Bid security deters frivolous bids and covers the gap if the low bidder backs out. Performance security assures completion if the contractor defaults. Payment security protects subcontractors and suppliers, who cannot lien public property.
Cash can be posted for all three, but it is most contentious as performance security because the amounts are larger and the holding period can span years. An 18-month roadway job followed by a one-year warranty creates a two-and-a-half-year lock on funds, and that is before change orders extend the timeline.
Surety bonds spread the risk to a surety, which underwrites and then, if necessary, finances or replaces the contractor. Cash bypasses that mechanism and gives the owner direct recovery. The trade is simplicity for liquidity. Whether that is wise turns on the parties’ risk tolerance and the region’s practice.
Legal frameworks that drive what is acceptable
You rarely get to pick your security form freely. Three constraints set the guardrails.
First, statutes and regulations. Federal contracts generally require surety bonds and list acceptable alternatives only in narrow cases, such as micro-purchases or specific grant-funded programs. State acts vary. Some allow cash or letters of credit up to defined thresholds. Others require a corporate surety licensed in the state with no alternative except in emergencies or if a waiver is documented. Public utility and transportation authorities often have their own rules, which can be stricter.
Second, procurement documents. The instructions to bidders and the general conditions define what counts as acceptable security, the percentage, how it may be posted, and what triggers forfeiture. The definitions matter. “Immediately available funds” can exclude a standby letter of credit with documentary conditions. “Unconditional” may require a clean, on-demand letter of credit rather than one requiring a default certification from an architect.
Third, banking law. A letter of credit must be issued by a qualifying financial institution. Some agencies specify minimum total assets, branch presence, FDIC insurance, and ratings. International bank letters often require a confirmed domestic bank to avoid cross-border enforcement issues. If the LC expires annually, the contract usually requires evergreen language with a 60 to 90 day non-renewal window to allow the owner to draw.
If you do not reconcile those layers at bid time, you will end up arguing technicalities after award, and that is not a fight you want with the clock ticking on a notice to proceed.
When an owner should favor cash
There are legitimate reasons for an owner to prefer cash or cash equivalents over surety paper. Smaller jurisdictions without experience handling default claims can find surety claims opaque and slow. A cash performance bond lets them draw quickly when they declare default, then hire completion work without negotiating with a third party. On projects where the owner’s schedule is critical, such as a school opening or a bridge tie-in during a railroad shutdown, that speed matters.
Market cycles play a role. In contractor failure waves, some sureties shorten the leash on financing and delay claim decisions. Owners that lived through those cycles sometimes specify cash to avoid reliance on surety decisions. Also, where the contractor pool is heavy with small, local firms that struggle to secure large bond lines, accepting cash or letters of credit can increase competition. You get more bidders when you reduce the friction of underwriting, though you must then underwrite liquidity risk yourself.
I have seen county drain projects under five million dollars switch to a cash or LC option and add three viable bidders, trimming prices by three to five percent. The county treasury built procedures to hold and invest the deposits within statutory limits. That is the catch. You are moving responsibility from the surety market to your finance department.
Why contractors push back
Cash ties up working capital. On a ten million dollar contract with a 100 percent cash performance bond, a contractor could have ten million dollars frozen for the duration of the job plus the warranty tail. Replace “cash” with a letter of credit and you still consume bank credit. Most bank facilities count an LC dollar-for-dollar against borrowing capacity. That squeezes payroll, equipment purchases, and bonding on other jobs.
A surety bond, by contrast, generally uses underwriting capacity rather than cash. A healthy contractor might carry bonded backlog of five to ten times working capital because sureties rate the firm’s overall financial strength and performance history, not the cash posted per job. Shift to cash and that leverage disappears.
There is also the risk of wrongful draw. Even sophisticated owners occasionally draw in a gray area to create leverage in a dispute over liquidated damages or punch list scope. With a surety, a contested claim triggers a claims process. With cash, you fight to get your money back. The law provides remedies, but time and fees are real, and the job still needs to move.
Pragmatically, contractors price these risks. Expect bids to rise by one to three percent on larger projects when cash security is required, sometimes more if the hold period is long or termination triggers are broad.
The mechanics: posting, holding, and releasing cash
The cleanest process starts at bid stage. The instructions should state the acceptable forms, the percentage, Axcess Surety and the holding vehicle. If cash, identify whether the owner will place the funds in a segregated, interest-bearing account and whether the interest accrues to the contractor. Many state statutes require public owners to hold deposits in interest-bearing accounts and credit the interest to the depositor, net of administrative costs. Others prohibit paying interest to avoid creating a debt-like relationship. Know your jurisdiction.
On award, the contractor delivers the deposit or LC before the notice to proceed. If it is an LC, legal counsel vets the draft for:
- Issuer qualifications, amount, and expiry or evergreen language. The draw mechanism, including what documents the owner must present. Assignment restrictions if the owner merges or the project is transferred to another public body. Conformity with the contract’s performance security clause, including extension through the warranty period.
Administration sometimes trips teams up. If the owner holds the cash, treasury must reconcile the account, report it as a liability, and manage audit trails. If the funds are substantial, the owner may use a third-party escrow arrangement to hold cash and define draw conditions with an independent agent. That adds cost but reduces temptation to draw improperly and provides comfort to contractors.
Release timing should be explicit. Owners often reduce the amount at substantial completion, then release the balance at final completion, while retaining a warranty reserve equal to two to five percent through the defects liability period. Set those stages in writing. A blanket “released upon final acceptance” for the entire amount forces contractors to carry large capital burdens longer than necessary and invites change order fights near the end.
What triggers a draw
Owners need clarity on draw conditions because you do not have a surety adjusting the claim. Most owners tie draw rights to a declaration of default under the contract after notice and cure. Some allow interim draws to cover specific unperformed work or liquidated damages. The tighter you define default, the less likely you are to face a wrongful draw dispute.
From experience, a workable approach looks like this: the owner issues a written notice of default identifying the breached obligations, provides a cure period consistent with the general conditions, and reserves the right to supplement the contractor’s forces. If cure fails, the owner may draw on the cash or LC in part or full to fund completion or to cover specific costs such as extended inspection, reprocurement premiums, or LDs. Document every step. When auditors arrive, paperwork is your shield.
If you structure the LC as “on demand,” keep in mind that banks honor facially conforming demands. That means your internal process must enforce the contract’s default preconditions. A bank will not police whether your default was justified. That task shifts to your legal and project management team.
Comparing cost and risk against surety bonds
Stakeholders often ask for a simple answer: which is cheaper. There is no single number because the cost flows through different channels.
With a surety bond, the contractor pays a premium, typically in the range of 0.5 to 3.0 percent of the contract value per year depending on size, credit, and scope. That cost is embedded in the bid price. With cash or an LC, the contractor bears opportunity cost and bank fees. LC fees commonly range Axcess Surety providers from 0.5 to 1.5 percent annually plus line usage impacts. The bigger cost is the loss of borrowing capacity. Firms that rely on working capital lines will either pass the cost into the bid or choose not to bid.
On the owner’s side, surety claims administration takes time but does not burden treasury. Cash imposes administrative load to hold, reconcile, and potentially invest funds within statutory limits. If you use an escrow, there are agent fees. If your team is not set up for that, budget for training and process design.
Risk allocation differs. Surety bonds offer a pathway to completion through the surety’s network, which can be a lifesaver on niche scope like specialized treatment plants. Cash gives you speed and control but requires you to procure completion and manage the risk you just took back.
Practical tips for public owners
A few ground-truth practices have saved projects and reputations.
First, align statute, policy, and documents. If your purchasing code allows cash or LC, update your standard specifications to reflect the choice, including model LC language vetted with your counsel. Do not copy a bank’s form letter of credit. Banks write those to minimize their obligations. Your form should be clean, on demand, and evergreen, with non-renewal notice long enough to exercise remedies.
Second, meter the amount to the risk. Full 100 percent cash performance bonds on short, low-risk jobs may be overkill. Consider stepping the required amount down at fixed milestones, or allow a blended approach, such as 50 percent LC plus 50 percent surety. Some agencies accept a surety performance bond with a small cash reserve to cover LDs. Blends can keep bidders in play while preserving recovery.
Third, protect against wrongful draws. Institute an internal default committee process. Before drawing on cash or an LC, require a short memo from project management and legal summarizing notice provided, cure opportunities, and the basis for default. It adds a day or two, but it reduces the likelihood of costly litigation.
Fourth, manage earnings and reporting. Where allowed, place deposits in interest-bearing accounts with daily liquidity so you can draw when needed. Define in the contract who receives the interest. If it is the contractor, state whether the interest is paid at release or periodically. Keep clean ledger entries and reconcile monthly. External auditors will ask.
Finally, plan for the tail. If your defects liability period is twelve months, do not forget that the security must extend through that period. For LCs, monitor expiry dates and enforce the evergreen clause. Diaries and alerts sound mundane, but I have seen multi-million dollar LCs lapse because no one watched the calendar.
Guidance for contractors weighing a cash requirement
Contractors with healthy surety lines often chafe at cash security, but sometimes you need to work within the requirement. The key is to assess your capacity and negotiate terms that minimize lock-up.
Start with your bank. Confirm the size of your LC facility and how an LC for this project will reduce other borrowing. Price the LC fee and confirm whether the bank requires collateral. Banks sometimes allow offsets, such as using a certificate of deposit as collateral, which you can fund with project cash flow once progress payments start. That arrangement still ties up funds but gives you flexibility.
If you post actual cash, treat it as a project-specific investment. Model the hold period, including warranty. Negotiate staged releases tied to substantial completion and acceptance of punch work. Ask for a provision that reduces the security proportionally for approved deductive changes or accepted portions of work. Owners sometimes agree if you make the administrative steps straightforward.
For the contract language, look closely at default and draw terms. Push for notice and cure periods that reflect the realities of construction. Ensure the owner must provide a written certification of default for an LC draw, and tie the amount of any draw to documented costs. You may not get everything, but the conversation often narrows overreaching language.
Price the risk. If cash security is unavoidable, load your general conditions appropriately. Share your rationale in pre-bid meetings. Owners who understand the cost drivers are more likely to adjust requirements on future bids.
Edge cases that deserve extra attention
Some project types magnify the pros and cons. Design-build mixes design risk and construction risk, which complicates default decisions. A cash performance bond can tempt an owner to draw at the first sign of design delay, even if responsibility is shared. Clear definitions of default and a dispute resolution path help.
Long-duration, multi-phase civil jobs create staggered acceptance points. Without staged security reductions, contractors carry outsized lock-ups. I have seen highway programs move to sectional acceptance with proportional security release to keep competition healthy.
Projects with federal grant funds can trigger layers of requirements that conflict. A state DOT may allow letters of credit, while the funding agreement demands surety bonds. Clarify early. If you learn after award that the funder will not reimburse unless a surety bond is in place, you will scramble to convert security midstream, which is awkward for both sides.
Finally, joint ventures create paperwork complexity. If a JV is the contractor, the LC issuer will underwrite both parents, and the owner must ensure the security remains valid if the JV dissolves after completion of earlier phases. Be explicit about successor obligations.
A brief example from the field
A mid-sized city sought bids for a three million dollar pump station upgrade. The purchasing ordinance permitted surety bonds or “equivalent cash security.” Historically, the city had painful experiences with surety claims that took months to resolve. They opted to request a cash performance bond via an irrevocable evergreen letter of credit for 100 percent of the contract price.
At the pre-bid, two regional contractors balked, noting their LC facilities were tight due to other work. The city listened and modified the request: 50 percent LC and 50 percent surety performance bond, staged releases reducing the LC portion to 20 percent at substantial completion and 5 percent through the 12-month warranty. They adopted model LC language with on-demand draw, but required a written certification of default signed by the city engineer and the procurement director.
Four bids came in instead of the usual two. The low bid was close to the engineer’s estimate. Midway through construction, a pump vendor missed a delivery window. The contractor accelerated at its own cost to protect the schedule, the city issued a small change for overtime inspection, and the parties moved on. At substantial completion, the city executed the agreed reduction, freeing the contractor’s LC capacity for another job. There were no defaults, but both sides had the comfort they needed, and the city’s finance team could administer the hybrid without straining capacity.
The bottom line on choosing cash security
Cash performance bonds give public owners immediacy and control, but they are blunt tools. They can ward off delays when default hits, broaden bidder pools in some markets, and simplify claim recovery. They also tie up capital, increase contractor pricing, and demand disciplined administration from the owner. Surety bonds, while sometimes slower to respond in a dispute, bring specialized completion resources and preserve contractor liquidity.
There is no universal best form. The smart move is to treat performance security as a design element of the procurement, not boilerplate. Size it to the risk, check it against statute, and write the mechanics cleanly. Consider blended approaches where your market needs relief. As for the phrase “cash performance bond,” use it precisely. If you want deposited funds, say so. If a letter of credit suffices, set the standards and the calendar alerts.
Handled with care, security becomes background noise on a well run job. Handled poorly, it becomes the story. The work is building the school, widening the road, tying in the water main before summer demand hits. The security should help you get there, not become the obstacle in your path.
A short checklist for owners considering cash or LC security
- Verify statutory authority and funding requirements for alternatives to surety bonds. Decide acceptable forms and amounts, then write clear, evergreen LC language and release milestones. Build treasury procedures for holding, investing, and reporting deposits or monitoring LC expirations. Calibrate draw conditions to the contract’s default process and require internal approvals before any draw. Communicate early with your market. Use pre-bid meetings to test whether requirements will deter competition.
Finally, to contractors scanning bid advertisements: when you see “cash performance bond” in the documents, read the fine print and do the math. If the project merits the capital lock-up, structure your financing and ask for staged releases. If not, pass and protect your balance sheet. There will be another job tomorrow.
