A Larger Opportunity Can Change Your Bonding Needs
The rapid growth of AI continues to create major opportunities for contractors. According to Stanford’s 2026 AI Index, 88% of organizations now use AI, fueling the rising demand for the data centers needed to power this technology.
In Part 1 of our data center construction series, we explored how to determine whether these fast-growing opportunities align with your experience, workforce, financial resources, and long-term growth strategy. But deciding that a project fits your business raises another important question: Can your current bond program support it?
Data center contracts tend to be larger, faster-moving, and more complex than other types of projects. Even if you're confident you can perform the work, your surety will need to assess how the contract fits with your existing financial and operational commitments.
Read on to learn what sureties consider during prequalification, how a major data center project can affect your bonding capacity, and how consulting with your bond professional before bid day can help you prepare for the opportunity.
Do Data Center Construction Projects Require Surety Bonds?
Some data center construction projects require bonds, but requirements can vary. Unlike many public construction projects, private data center projects don't automatically require surety bonds.
Depending on the project, bond requirements may be established by the owner or developer, lender, general contractor, construction contract, or subcontract terms. Surety bond requirements may apply to both general contractors and subcontractors. Major electrical, mechanical, utility, and infrastructure contractors may also need to provide bonds, especially if their work represents a significant portion of the overall project.
Before bidding, carefully review the project solicitation, contract, and bond forms so you understand the requirements if you're awarded the work.
What Types of Surety Bonds May Be Required?
Depending on the data center project and your role in it, you may encounter these three common types of construction bonds:
- Bid bonds: A bid bond guarantees that you'll honor your bid, enter into the contract, and provide the required final bonds if you're awarded the work.
- Performance bonds: A performance bond guarantees that you'll fulfill your obligations under the bonded contract.
- Payment bonds: A payment bond guarantees that you’ll make timely payments to your subcontractors, labor providers, and material suppliers.
Note: Receiving a bid bond doesn't automatically guarantee your approval for the project’s performance and payment bonds. If the final contract amount, scope, schedule, or terms change materially after bidding, your surety may need to reevaluate the project before issuing the final bonds.

What Does Surety Prequalification Involve?
Before supporting a major data center project, your surety will want to understand whether your business has the financial and operational capacity to complete the work successfully. During underwriting, your surety may consider your:
- Financial strength, working capital, and net worth
- Profitability and cash flow
- Current backlog
- Relevant project experience
- Management capacity
- Labor and equipment availability
- Project owner, schedule, and contract terms
- Overall growth plans
No single factor determines whether you'll qualify. Instead, your surety will look at how these pieces work together. For example, strong financial statements may support your bond request, but your surety may still have concerns if your management team is already stretched thin across several large projects.
What Financial Information Will Your Surety Review?
As your bond requests increase in size, your surety may require more detailed financial information during underwriting. Here are some of the records they may request:
Financial Statements
You may need to provide fiscal-year-end and interim financial statements, along with supporting schedules. Larger bond requests may also require CPA-prepared financial statements.
WIP Schedule
Your surety may use your work-in-progress (WIP) schedule to assess how much work you currently have underway and whether your active projects are performing as expected, so be prepared to provide the following WIP information:
- Current contract values
- Costs and billings to date
- Estimated costs to complete
- Expected gross profit
- Remaining backlog
- Projected completion dates
Accounts Receivable and Payable
Your accounts receivable and payable aging schedules can help your surety identify potential cash-flow issues, such as:
- Slow-paying customers
- Disputed receivables
- Past-due obligations to suppliers and subcontractors
Bank and Credit Information
Your surety may review your available cash, outstanding debt, equipment financing, and bank lines of credit to assess your overall liquidity. While access to credit can provide additional financial flexibility, it isn’t a substitute for sufficient working capital.

What Are Single-Project and Aggregate Bonding Limits?
When you’re considering a project that’s larger than your typical work, it’s important to understand your bonding capacity, which typically includes two key limits:
- Your single-project limit represents the largest individual bonded contract your surety is prepared to support, subject to review of the specific opportunity.
- Your aggregate limit represents the total amount of bonded work your surety may support across all of your active projects.
For example, let’s say you have a $5 million single-project limit and a $12 million aggregate limit. A $4 million data center subcontract would fall within your single-project limit. But if you already have $10 million in bonded work underway, you may not have enough aggregate capacity available to support the new project.
Keep in mind that these limits aren't guaranteed credit lines. Your available capacity may fluctuate based on your financial results, backlog, project performance, changes in ownership or management, market conditions, and new contract details.
Can You Increase Your Bonding Capacity?
Yes. You may be able to increase your bonding capacity over time by:
- Retaining earnings
- Building up your working capital
- Completing your current projects profitably
- Maintaining accurate financial statements and WIP schedules
- Strengthening your project management systems
- Adding experienced leadership to your team
- Expanding gradually into larger projects
- Maintaining strong banking relationships
- Discussing upcoming opportunities with your surety professional early
Keep in mind that bond capacity increases aren’t automatic. If you request more capacity, your surety will need to evaluate your current financial position, project performance, backlog, and overall ability to manage additional work before deciding whether to support the request.

How Does Your Backlog Affect Your Bonding Capacity?
Your surety doesn't evaluate a new data center project in isolation. Instead, it considers how the project fits within your existing workload. A major award can place additional demands on your labor, management team, equipment, and working capital.
As your backlog grows, sureties want to verify whether you can take on the additional work without stretching your resources for existing commitments. That means looking at your entire backlog—not just your bonded projects.
Sureties may ask additional questions during underwriting if you currently have:
- Several large projects starting or finishing around the same time
- A large portion of your backlog concentrated with one owner or general contractor
- Multiple projects in unfamiliar geographic markets
- Existing projects that are experiencing delays, losses, or other performance issues
- A backlog that’s growing faster than your working capital or management capacity
None of these factors automatically disqualify you for additional bonding. However, they can affect how your surety evaluates your available capacity and ability to take on another major project.

Why Does the Data Center Construction Contract Matter to Your Surety?
Your company's financial strength isn't the only source of risk. The data center construction contract itself can also affect whether a surety is comfortable supporting the project.
Data center contracts often include aggressive schedules, phased delivery requirements, testing and commissioning obligations, and strict completion requirements. Contract terms that may warrant closer surety review include:
- Liquidated damages
- Aggressive milestone requirements
- Delay and acceleration clauses
- Pay-if-paid or pay-when-paid provisions
- Retainage
- Change-order procedures
- Consequential damages
- Broad indemnification
- Warranty requirements
- Termination provisions
- Unusual bond forms
Before committing to a data center project, review the contract and bond forms carefully. Consulting with a qualified legal and insurance professional can help you identify obligations that may create additional exposure for your business.

Does Previous Data Center Experience Affect Bond Approval?
Previous data center experience can strengthen your bond request, but it isn't necessarily the only way to demonstrate that you're prepared for the work. Sureties can also look to your relevant experience with other complex projects, such as:
- Hospitals
- Manufacturing facilities
- Power and utility projects
- Telecommunications infrastructure
- Laboratories
- Government facilities
- Other mission-critical construction
Your surety will consider how the size of the new data center project compares with projects your business has successfully completed in the past. For example, moving from $2 million projects to a $3 million contract may be easier to support than jumping directly to a $10 million project.
Beyond project size, your surety will consider how closely your existing experience prepares you for the specific demands of the new project, including your:
- Familiarity with the proposed scope, schedule, and delivery method
- Team's experience working in the project's geographic market
- Relationships with reliable suppliers and subcontractors

How to Prepare Your Bond Program Before Bid Day
If you're considering a data center opportunity, don't wait until the bid deadline to determine whether your bond program can support it. Instead, take these steps early to set yourself up for success:
- Share the opportunity with your surety right away: As soon as you're seriously considering a new data center project, share the project name, location, owner or general contractor, estimated contract amount, scope, bid date, proposed schedule, bond requirements, contract, and bond forms with your surety professional.
- Update your financial information: Make sure your financial statements, WIP schedule, and other supporting information reflect your current position, as outdated information can make it harder for the surety to evaluate your request efficiently.
- Review your existing backlog: Consider your available bonding capacity, projects nearing completion, underperforming jobs, and pending awards that could overlap with the data center project.
- Develop a project-specific plan: Be prepared to explain who will manage the project, how you'll staff it, which suppliers and subcontractors you'll rely on, how you'll handle long-lead materials, and how you'll support the project's cash-flow needs.
- Look beyond this one bid: Share your broader opportunity pipeline with your bond professional so you can evaluate how one major award could affect your capacity to pursue future work.
