Risk management is essential in any major capital project. Owners, contractors, and designers all bring different risk exposures to the table, and protecting against those risks through bonds and insurance is both a contractual and financial necessity.
Many insurance and bonding requirements are dictated by law or funding sources, especially for public institutions. But where requirements are flexible, such as at private universities or in P3 partnerships, B&D can help shape those requirements and extract the most value for our clients. By aligning insurance and bonding strategies with your institution’s goals, B&D helps you balance protection, compliance, and cost efficiency.
Insurance: Transferring risk
An insurance policy is a contract between an insured party and an insurer that provides financial protection against defined losses, and this is a common way to manage project risk. The insured pays a premium, and if a covered event occurs, the insurer pays the claim (up to the policy limit) and absorbs the loss.
Types of insurance in design & construction
Just as individuals may purchase different insurance policies for their car, home, or health, the design and construction process rely on a suite of specialized policies. The table below summarizes the types of insurance commonly encountered, as well as who they protect and when they apply.
| Type | Who it protects | Purpose / typical use | Example |
| Builder’s Risk | Owner or contractor | Covers damage to the work under construction (e.g., fire, storm, vandalism). Essentially “property insurance during construction.” | A storm damages the new central plant’s roof mid-construction; the policy pays for repairs. |
| Commercial General Liability (CGL) | Owner, public, and contractor | Covers bodily injury or third-party property damage from contractor operations. | A pedestrian is injured near the jobsite by falling debris. |
| Worker’s Compensation | Employees and employers | Provides medical and wage benefits for job-related injuries or illnesses. These are state-regulated programs in which eligible employers must participate. | A worker is hurt lifting equipment on-site. |
| Professional Liability / Errors & Omissions (E&O) | Designers and design-builders | Covers design errors or omissions that cause financial loss or rework. | Water infiltration due to improper flashing details causes damage. |
| Automotive Liability | Contractor | Covers damages or injuries from vehicles used on the project. | A site truck collides with another vehicle. |
| Inland Marine/ Transportation/ Cargo Insurance | Owner, contractor, or supplier (whoever holds title during transit) | Covers materials, equipment, or fixtures while they are transported to or from the project site. | A custom air-handling unit is damaged in a truck accident while being delivered to campus. |
| Pollution Liability | Owner and contractor | Covers cleanup and damages due to contamination or hazardous materials. | A piece of equipment leaks fuel or hydraulic oil into storm drains or wetlands. |
| Cyber Liability | Owner and contractor | Covers losses from cyber incidents that compromise data or building systems. | A contractor’s system is phished or hacked, exposing joint data or financials. |
| Contractor-Controlled (CCIP) or Owner-Controlled (OCIP) Insurance Policy |
Owner or contractor, and all enrolled subs | Wrap-up policies that replace individual CGL and workers’ comp with a single sitewide policy, ensuring uniform coverage and minimizing disputes between insurers.
Because of the administrative burden, these policies are typically only used on single large projects (>$100M) or by large contractors with multiple smaller projects on a rolling basis (combined > $250M). |
Water leaks appear on several floors after heavy rain. The waterproofing sub blames the window installer, who blames the masonry subcontractor for improper flashing installation. Instead of dealing with three different insurers and policies, all three trades are covered under one carrier. |
| Subcontractor Default Insurance (SDI, a.k.a. “SubGuard”) | Contractor | Protects the prime contractor from losses caused by subcontractor default. It benefits the contractor—not the owner. | A roofing subcontractor stops paying its suppliers and workforce despite receiving progress payments. Materialmen file liens against the project. The contractor can use the proceeds from an SDI claim to pay suppliers directly and clear the liens. |
| Umbrella / Excess Liability | Various | Extends coverage limits beyond base policies. Often added when clients require higher coverage than a contractor’s standard limits. | A university requires $50M in liability coverage; the contractor’s standard policy only covers $40M, so they buy an excess policy to meet that threshold. |
Understanding the purpose of the policy and who is protected can help determine whether the cost of the policy is justified as a separate, project-specific line item in project pricing (e.g., Builder’s Risk, CCIPs/OCIPs), or if it should be characterized as an overhead cost that should be absorbed in the contractor’s or designer’s fee (e.g., CGL or automotive liability).
How insurance costs are priced
Both bonds and insurance are typically “below the line” costs in a contractor or developer’s proposal. This means that they are not direct or “hard” costs associated with the materials, equipment, and labor necessary to physically construct the project. Rather, they are indirect or “soft” costs that are essential to the work but not part of the physical construction.
Insurance premiums are often expressed as a percentage of hard construction costs (typically 1-3% in total). Actual rates depend on factors such as:
Bonds: Guaranteeing performance
Bonds are another form of risk management, but they function differently from insurance. A bond is a financial guarantee from a surety company that the contractor will meet its contractual obligations to the project owner.
Every bond involves three parties:
The surety’s liability is capped by an amount called the “penal sum,” usually equal to the contract value.
Types of bonds in design & construction
Common bond types encountered during the construction procurement process include:
Payment and performance bonds are often statutorily required on public projects. In private or P3 settings, project owners may still choose to require them to protect against non-performance or lien exposure.
Note: These construction-related bonds differ from the municipal or revenue bonds that institutions may issue to finance projects. Those are debt instruments and fall outside the scope of this article.
How bonds are priced
Like insurance, bond premiums are typically expressed as a percentage of the contract value. The exact rate depends on factors such as the type of bond, the size of the project (and thus the size of the penal sum), and the contractor’s financial strength, credit rating, and performance history, but typically range between 0.5%-1.5% of the contract value. Larger, financially strong contractors typically secure lower rates. Because the surety’s guarantee is based on the contractor’s credit and reputation, the contractor’s bonding capacity is often seen as a proxy for a contractor’s financial stability.
Comparing bonds vs. insurance
Simply, insurance covers losses while bonds guarantee performance. With insurance, the insurer assumes some portion of the risk in exchange for a premium. If a claim occurs, the insurer absorbs the loss, up to the policy limit. The owner is an indirect beneficiary because the funds recovered by the contractor through insurance claims are used to help the project recover, eliminating or reducing the need to dip into project contingency.
In comparison, if the principal/contractor defaults on a bond, the surety must step in to make things right—either by financing completion, hiring another contractor, or reimbursing the obligee/owner (up to the bond’s penal sum). Unlike with insurance, the surety does not expect to absorb the loss. Rather, the surety will pursue the contractor for reimbursement.
Contractors have a strong incentive to avoid bond claims because they must reimburse the surety and risk losing future bonding capacity. For this reason, the surety can be a powerful ally if the contractor defaults. The surety has both the means and motivation to intervene early when problems arise. This leverage doesn’t exist with insurance—the insurer’s obligation is only to pay for covered losses, not to complete the project.
Insurance compensates for losses, while bonds enforce accountability. These are both valuable risk management tools, with different nuances to how money flows and how behavior is shaped when challenges arise.
Avoiding redundancy and aligning coverage
Avoiding redundant coverage
In complex projects, multiple instruments may unintentionally cover the same risk. These overlaps can add unnecessary cost and even slow down claims when insurers dispute which policy should apply.
Examples of potential duplications include:
B&D can review proposed coverage frameworks to identify where potential duplications exist and help institutions pay for the right protections once, not twice.
Aligning coverages with contract responsibilities
Construction contracts are fundamentally risk-allocation tools. Provisions on indemnity, warranties, force majeure, and others determine which party is responsible for which types of losses. However, even well-negotiated contracts can fall short if the required insurance does not match each party’s assumed risks. Those contractual obligations only function as intended if the responsible party’s insurance policies cover the risks they’ve agreed to bear.
Common misalignments include:
B&D can help project owners verify that policy requirements reflect contractual intent, and that policy limits and exclusions are sufficient and appropriate. This alignment helps make sure that risk transfer mechanisms actually work as intended, protecting both the owner and the contracting parties from surprises when a claim occurs.
Strategic Choices: Who should carry Builder’s Risk?
Builder’s Risk can be purchased by either the owner or the contractor/developer. The parties should coordinate to ensure that Builder’s Risk coverage is obtained but not duplicated.
B&D can help your institution evaluate the pros and cons of each approach, based on relevant project-specific factors such as financing structure, delivery method, and scope.
Takeaways for project owners
A strategic understanding of bonds and insurance tools can help institutions strengthen their project delivery, minimize disputes, and ensure dollars spent on risk management deliver the most value.
While our guidance as trusted advisors should never replace formal legal or insurance advice, B&D can help institutions:
Effective use of bonds and insurance is not just about compliance. By engaging with risk management early, B&D helps institutions strategically protect their investments, safeguard project continuity, and deliver facilities that serve their mission for decades to come.
