Your firm just won a design contract for a mixed-use commercial project. Buried in the contract's insurance exhibit: “Owner shall procure Builders Risk Insurance. Architect shall be named as additional insured.” Your office manager forwards it to you with one question: does this mean your firm needs to buy a policy, or just make sure you're on someone else's?
That distinction trips up AEC firms constantly, and getting it wrong can leave a real gap in coverage. Builders Risk Insurance protects a building and its materials during construction, but most guides to the topic are written for the owner buying the policy, not the architect, engineer, or general contractor (GC) trying to figure out where they fit on it.
This guide covers what Builders Risk actually does, where it stops, and how it interacts with the Professional Liability, also called Errors & Omissions (E&O), and General Liability coverage your firm already carries.
Key Takeaways
- Builders Risk Insurance covers physical loss or damage to a structure and its materials during construction. It doesn’t cover professional errors, faulty design, or general liability.
- "Damage due to faulty design, planning, or workmanship" is a standard exclusion in Builders Risk policies. For architects and engineers, that gap is what Professional Liability Insurance (also called Errors & Omissions Insurance) is designed to fill.
- Who pays for Builders Risk is determined by the project contract, not by default. Either the owner or the GC may be responsible. The AEC firm is rarely the buyer but often needs to verify their status on the policy.
- Architects and engineers may be required to be added as additional insureds on a Builders Risk policy, not named as the primary insured. These are not the same thing.
- Builders Risk, Professional Liability, and General Liability Insurance each cover a different layer of risk on a construction project. A complete AEC coverage program typically needs all three.
What Is Builders Risk Insurance?
Builders Risk Insurance (also called Course of Construction Insurance) is a temporary property insurance policy that covers a building and its materials during the construction phase. It activates when construction begins, typically when materials are first delivered to the site, and it expires when the project is complete.
More specifically, Builders Risk sits in the Inland Marine category of insurance, which covers property in transit or in a temporary location. During construction, a building is essentially both: it's not yet a finished structure, materials are moving on and off site, and the risk profile changes week to week as the build progresses.
The policy is project-specific. It's tied to a single project, at a single location, for a defined period of time. When construction wraps and the building is occupied or put to its intended use, Builders Risk ends. The owner then transitions to a permanent commercial property policy.
For AEC firms, the most important thing to understand upfront is what category of insurance this is: it's property coverage. It protects physical assets. It isn’t Professional Liability coverage, and it isn’t General Liability coverage. Those distinctions matter more than most project contracts make clear.
What Does Builders Risk Insurance Cover?
A standard Builders Risk policy covers physical loss or damage to the structure and materials from a defined set of perils. At a minimum, most policies cover:
- Fire and smoke
- Theft
- Vandalism
- Windstorm, hail, and lightning
- Explosions
- Structural collapse
Coverage extends to the building itself as well as materials and fixtures on-site, materials stored temporarily off-site, and materials in transit to the job site. Lumber delivered but not yet framed is covered. Equipment staged in a parking lot is covered. Materials being trucked in can be covered.
Most policies can also be extended to cover soft costs: indirect expenses incurred when a covered loss causes a construction delay. This can include additional interest on construction loans, real estate taxes during an extended timeline, and extended rental income loss for the project owner. Soft cost coverage is usually an endorsement, not automatic, so it's worth confirming when reviewing a policy.
Common exclusions from the standard form include flood, earthquake, and wind in certain coastal zones. These can sometimes be added by endorsement depending on the market, the carrier, and the project location.
What Builders Risk Insurance Doesn’t Cover
For AEC professionals, the gaps in Builders Risk coverage are where your own policies need to pick up.
The Professional Liability Gap
The most important thing Builders Risk doesn’t cover is professional liability. Claims arising from design errors, coordination failures, or professional judgment are explicitly excluded from standard Builders Risk policies.
The specific exclusion language varies by carrier but almost always includes something like: “damage due to faulty design, faulty planning, faulty workmanship, or faulty materials.” For architects and engineers, this exclusion isn’t a technicality. It defines the boundary between what Builders Risk covers and what your Professional Liability Insurance for AEC firms (also called Errors & Omissions Insurance) is designed to cover.
Here's how that boundary works in practice. If a fire damages framing materials at 40% completion, Builders Risk responds. If water intrusion during construction is traced back to an error in the drainage specification your firm produced, that's a professional liability claim. Builders Risk won't pay for it. Your E&O policy will need to.
The same logic applies to coordination failures, missed scope details, and documentation gaps. The physical loss may be covered by Builders Risk. The professional negligence allegation that follows often won't be.
No General Liability Coverage
Builders Risk also doesn’t cover bodily injury or third-party property damage. That's the job of General Liability Insurance.
If a site visitor is injured on a construction site, General Liability responds. If a contractor's equipment damages a neighboring property, General Liability responds. Builders Risk covers the structure and materials being built. It doesn't cover what happens to people or property outside that defined scope.
For AEC firms, this is relevant because you're often on-site in a supervisory or inspection role. Bodily injury exposure exists any time your team is on the project site. Your firm's own General Liability policy needs to address that, regardless of what Builders Risk coverage the owner or GC carries.
Other Notable Exclusions
A few other exclusions worth knowing for AEC projects:
- Employee theft: Builders Risk doesn't cover theft by employees. Crime Insurance addresses that separately.
- Wear and tear: Normal deterioration or mechanical breakdown during construction isn't covered.
- Faulty workmanship: If a contractor's work simply fails, Builders Risk typically doesn't cover the cost to redo it. It may cover resulting damage to other covered property, depending on whether the policy includes an ensuing loss provision, but the rework cost itself usually isn't covered.
Who Pays for Builders Risk Insurance?
The contract determines this, not a default rule. Either the project owner or the general contractor may be responsible for procuring Builders Risk Insurance, depending on how the agreement is written.
On large commercial and public projects, it's common for the owner to carry Builders Risk as part of their overall project financing structure. On residential and smaller commercial jobs, the general contractor often carries it. Design-build contracts can complicate this further, since the design and construction responsibilities may sit with the same party or with closely affiliated entities.
For AEC firms, the practical question isn't usually "who pays?" It's "what's my status on the policy?" Payment and insured status are separate things. An owner can pay for a Builders Risk policy and still fail to add the architect and structural engineer as additional insureds. When a covered loss occurs, that distinction matters.
If your contract mentions Builders Risk, confirm who's responsible for procuring it and whether your firm is expected to be on the policy. Then verify. Get a certificate of insurance showing that you've been added before construction starts, not after a loss occurs.
Are Architects and Engineers Covered by Builders Risk Insurance?
Yes, but almost never as the primary named insured. Design professionals on a project are typically added to the policy as additional insureds, which is a meaningful but more limited form of coverage.
Named Insured vs. Additional Insured
The named insured is the entity that owns the policy: typically the project owner or the general contractor. They have full rights under the policy, control over coverage decisions, and direct standing with the carrier.
An additional insured is a party added to the policy by endorsement. The coverage is real, but it's narrower in several ways. Additional insureds can't make independent decisions about the policy, their coverage is contingent on the named insured keeping the policy active, and their protection is generally limited to claims arising from the named insured's operations rather than their own professional services.
For architects and engineers, that last point is critical. Your additional insured status on a Builders Risk policy doesn’t extend to claims arising from your design work. That's still your firm's Professional Liability Insurance.
What to Verify Before a Project Starts
When a project contract references Builders Risk Insurance, review it before signing and clarify the following:
- Who is responsible for procuring the policy? Confirm this is explicitly addressed, not assumed.
- Are you expected to be an additional insured? If so, request a certificate of insurance showing the endorsement before work begins.
- Do the coverage limits match the project scope? Inadequate limits are a risk that falls on the named insured, but you want to know going in.
- Does the policy period cover the full expected construction timeline? Projects run long. Make sure the policy can be extended, and confirm who's responsible for requesting extensions.
- What are the exclusions? Ask specifically about the faulty design and faulty workmanship exclusions so you understand where your E&O policy needs to pick up.
These aren't adversarial questions. They're the same due diligence any AEC professional should bring to any contract review.
How Much Does Builders Risk Insurance Cost?
Builders Risk Insurance is typically priced as a percentage of the total construction value, with the actual rate depending on project type, location, construction materials, timeline, and selected endorsements.
According to WTW's 2025 Insurance Marketplace Realities Spring Update, rates for non-high-hazard projects are largely stabilizing, while high-hazard and catastrophe-prone builds continue to face upward pressure. The report also notes that recent tariff increases on building materials (steel, lumber, aluminum) are adding to overall construction values, which directly affects Builders Risk premiums since coverage is typically rated on total contract value.
The main underwriting factors include:
- Project location: Proximity to fire stations, flood zones, and coastal or wind-prone areas all affect pricing
- Construction type: Wood-frame construction carries more risk than masonry or steel
- Project timeline: Longer construction periods mean more exposure for the carrier
- Optional endorsements: Flood, earthquake, soft cost coverage, and installation floaters each add to the premium
For AEC firms that are typically additional insureds rather than the primary policyholder, this cost usually isn't yours to control. But understanding the cost structure helps when evaluating whether a project's coverage program is adequately scoped for its complexity.
How Builders Risk Fits Into the AEC Coverage Picture
Builders Risk, Professional Liability, and General Liability Insurance each cover a different layer of risk on a construction project. They're designed to be complementary, not redundant.
Here's how the three layers work together on a typical commercial project:
- Builders Risk Insurance covers physical loss or damage to the structure and materials during construction. It responds to fire, theft, weather events, and similar property perils.
- Professional Liability Insurance (E&O) covers claims that your professional services caused financial harm. Design errors, coordination failures, and standard-of-care allegations fall here. Builders Risk doesn’t cover these.
- General Liability Insurance covers third-party bodily injury and property damage that doesn't arise from your professional services. Site accidents, damage to neighboring property, and similar incidents fall here.
A scenario that illustrates how these interact: A water intrusion event occurs mid-construction. Investigation identifies three contributing factors: a severe rainstorm (covered by Builders Risk), an error in the drainage specification your firm produced (Professional Liability claim), and a subcontractor who punctured a waterproofing membrane (the GC's General Liability, and potentially your Professional Liability if you failed to catch it during a required site observation). Three separate policies, potentially three separate claims, each responding to its own layer of the event.
AEC firms that understand how these policies interact are in a better position to review contracts, verify coverage adequacy, and know where their own exposure actually sits. For a full breakdown of what architecture, engineering, and construction insurance programs need to cover, see our comprehensive guide.
Building a coverage program that reflects how your firm operates, what project types you take on, and what your contracts actually require isn't something any single policy handles. A broker with AEC expertise can help you build it right. Talk to a Vouch advisor about your firm's coverage program.
What This Means for Your Firm
Builders Risk Insurance is one piece of a three-part coverage picture on any construction project, and it's the piece most contracts mention without fully explaining. Knowing what it covers, who's responsible for it, and where your firm's status sits on the policy is what turns a contract review from a formality into actual risk management.
The next time a project contract references Builders Risk, you'll know exactly what to ask: who's procuring it, whether your firm needs to be an additional insured, and where the coverage stops and your own Professional Liability picks up. That's the kind of clarity that protects your firm before a claim ever surfaces, not after.
Frequently Asked Questions
What's the difference between Builders Risk Insurance and General Liability Insurance?
Builders Risk Insurance and General Liability Insurance cover different things. Builders Risk is property coverage: it covers physical loss or damage to the structure and materials under construction from perils like fire, theft, and weather. General Liability Insurance covers third-party claims of bodily injury or property damage. If a fire damages the building, Builders Risk responds. If someone is injured on the site, General Liability responds. Neither covers professional errors from the design team. That's what Professional Liability Insurance (E&O) is for.
Who pays for Builders Risk Insurance, the owner or the contractor?
The project contract determines this, and it varies by project type. On large commercial builds, the owner often carries Builders Risk. On residential and smaller commercial projects, the general contractor frequently does. For AEC firms, the more important question is your status on the policy, regardless of who pays. Confirm whether you're expected to be an additional insured and get a certificate of insurance showing the endorsement before the project starts.
Are architects and engineers covered under Builders Risk Insurance?
Architects and engineers can be covered under Builders Risk Insurance as additional insureds, but almost never as the primary named insured. The distinction matters: additional insured status gives you real but limited protection, and it doesn't extend to claims arising from your professional services. Your firm's Professional Liability Insurance covers those. If your contract requires Builders Risk coverage, ask specifically whether you'll be added as an additional insured and confirm the endorsement with a certificate of insurance before construction begins.
What does Builders Risk Insurance not cover?
The most significant exclusions for AEC professionals are professional liability (damage arising from faulty design, planning, or professional judgment), General Liability (bodily injury and third-party property damage), and employee theft. Standard exclusions also include wear and tear, mechanical breakdown, and typically flood and earthquake unless those coverages are specifically added. The faulty design exclusion is particularly important: it's the reason architects and engineers need Professional Liability Insurance in addition to any Builders Risk coverage they may be named on.
Is Builders Risk Insurance required?
Builders Risk Insurance isn't required by law in most cases, but it's commonly required by construction lenders as a condition of the construction loan, by public project contracts, and by owner contracts on commercial projects. The project contract typically specifies who needs to carry it, at what limits, and who else needs to be named as an additional insured. AEC firms should review these requirements during contract review, before signing.
How long does Builders Risk Insurance last?
Builders Risk Insurance is temporary by design. The policy typically ends when the building is occupied, when it's put to its intended use, or when the policy term expires. Policy terms are often set at 6 or 12 months, aligned with the expected construction timeline. If a project runs long, the policy needs to be extended, and that requires an active request from the named insured. For AEC firms engaged on longer projects, confirming the policy period during contract review, and knowing who's responsible for requesting extensions if the schedule shifts, is worth the five minutes it takes.
