Steel Building Insurance: CAR/EAR Cover, Bonds & Claims
Daytime steel erection site—crawler crane lifting an H-column, a helmeted engineer recording on a clipboard, with translucent policy and guarantee documents layered in the corner, cool blue professional tone.
A steel building project moves through three risky worlds: factory fabrication, ocean freight, and site erection. Each has its own loss scenario—and a standard property policy usually covers none of them. A steel building insurance program is not one product. It is a stack: CAR/EAR cover during construction, marine cargo cover for the voyage, a performance bond against non-delivery, and, for large plants, delayed-start-up protection. Miss one layer and a single dropped column or a storm during erection can erase your margin.
This guide explains what each policy actually covers, who is supposed to buy it under your trade terms, how much to insure, how to file a claim without getting denied, and the rejection traps buyers overlook. For warranty claims after handover and for reviewing your contract clauses, see our steel building warranty & claim and steel building contract review guides. This one is about construction-phase risk transfer—before the keys are handed over. That is where a properly layered steel building insurance program pays for itself.
CAR vs EAR vs Builder's Risk — What They Actually Cover
The backbone of any steel building insurance program is the construction-phase all-risks policy. In most of the world it is called Construction All Risks (CAR); in the United States the same product is known as builder's risk insurance. For steel frames specifically, you will also see Erection All Risks (EAR). Understanding the difference prevents a costly coverage gap.
Construction All Risks (CAR) covers the whole works—including owner-supplied equipment—from mobilization to practical completion. Its perils typically include fire, storm, flood, lightning, construction negligence, and sudden accidental damage, plus a third-party liability extension. Both owner and contractor are usually named as joint insureds, and the sum insured is set at the contract value plus freight, duties, and an allowance for profit. Drawdown on construction milestones is explained in our steel building payment milestones article.
Erection All Risks (EAR) is a sibling policy aimed squarely at the lifting and installation phase. It weights cover toward things that go wrong during erection—a column overturning, a component colliding mid-lift, or installation error damaging already-placed steel. Steel-frame projects often buy EAR outright, or a CAR policy whose erection section is broad enough to behave like EAR. Deductibles typically run 0.5%–1% of the sum insured, with a minimum of roughly $1,000–$5,000 (varies by insurer).
Builder's risk (U.S.) is functionally the same all-risks product under an American name. Whether the owner or the contractor buys it depends on the contract template—AIA documents usually put it on the owner; many FIDIC arrangements put it on the contractor.
What these policies do not pay is as important as what they do. They generally exclude the cost of design error itself (though loss caused by that error during construction is usually covered), wear and tear, inherent defects, war, and strikes. Knowing the exclusions prevents a nasty surprise at claim time. For a deeper dive into the construction-phase policy specifically—material damage to the frame during erection, third-party liability to neighbors, delay-in-start-up cover, and the claim path from incident to settlement—our detailed construction all-risk (CAR/EAR) policy guide walks through exclusions, deductibles, and premium structure (typically 0.3%–1.0% of contract value) for the CAR/EAR product.
Insurance pays to repair the building; it does not pay to keep production running while the frame is being fixed. A critical production line that goes down for 48 hours can lose a key customer permanently—regardless of how well the CAR claim is handled. Our guide to disaster recovery and BCP planning covers how to structure a business continuity plan: BIA-driven RTO targets, backup generator sizing, evacuation drill schedules, and the pre-defined 72-hour recovery sequence that restarts operations while insurance adjusters are still assessing the structural damage.
Table 1: CAR vs EAR vs Builder's Risk
| Feature | CAR (Construction All Risks) | EAR (Erection All Risks) | Builder's Risk (U.S.) |
|---|---|---|---|
| Phase covered | Whole construction project | Lifting & installation stage | Whole construction project |
| Key perils | Fire, flood, storm, negligence, TPL | Collapsed columns, component collision, installation damage | Same all-risks perils as CAR |
| Named insureds | Owner + contractor (joint) | Usually contractor + owner | Owner or contractor per AIA/FIDIC |
| Sum insured basis | Contract value + freight + duties | Erection contract value | Completed value of works |
| Typical deductible | 0.5%–1% of sum insured | 0.5%–1%, min ~$1,000–$5,000 | Per-occurrence deductible |
| Best fit | Full build projects | Steel-frame erection packages | U.S. domestic projects |

Marine Cargo Insurance for Steel Components
Long before the first column goes up, your steel has already traveled thousands of nautical miles. Marine cargo insurance for steel components is a separate policy from CAR, and the Incoterms you signed decide who arranges it. Under ICC Incoterms & insurance obligations, CIF and CIP place the cargo-insurance duty on the seller; FOB and FCA place it on the buyer. If you buy CIF, verify that your company is named as the loss payee—otherwise the claim check goes to the seller, not you.
Steel moves in containers and on breakbulk ships, and losses are common: containers dropped in port, steel sweating and rusting in tropical holds, wet damage to coated members, or hooks piercing cladding. The standard policies are the Institute Cargo Clauses A (all risks), B, and C, published by the Institute & Lloyd's Underwriting Association (IUA). Clause A is the usual choice for fabricated steel; war and strikes are added separately. Cover is typically set at CIF value × 110% to include expected margin.
Packaging and rust-prevention evidence matter as much as the policy wording. When a claim arises, the underwriter will ask for packing photos, the packing list, the mate's receipt, and the opening survey report. That is why disciplined export packaging and a pre-shipment inspection are not just quality steps—they are claims evidence. Because the sum insured is based on CIF value, and CIF value includes duty (which itself depends on the HS classification and the steel certificate of origin you present at customs), a missing or incorrectly completed origin form can both raise your duty bill and lower the recoverable sum insured—request the correct CCPIT form before the vessel sails. See our guides on steel building shipping & packaging and steel building third-party inspection, and estimate the voyage cost in steel building shipping logistics cost.
Table 2: Cargo Insurance Coverage by Incoterm
| Incoterm | Who Arranges Cargo Cover | Typical Cover Level |
|---|---|---|
| FOB / FCA | Buyer | Buyer names own insurer; Clause A all risks |
| CIF | Seller (minimum cover only) | Clause C minimum; buyer should top up |
| CIP | Seller (higher cover) | Clause A all risks; verify buyer is loss payee |
| DAP / DPU / DDP | Seller | Seller arranges to named place; buyer still checks |
Confirm the exact clauses and beneficiary in the sales contract and policy schedule.
Performance Bonds & Advance Payment Guarantees
Insurance protects the physical works; bonds protect the payment relationship. A performance bond is a bank or surety guarantee paid to the owner if the contractor fails to perform—typically 5%–10% of contract value. It is standard on EPC and government projects and costs the contractor roughly 0.5%–2% of the bonded amount per year, subject to a credit line.
Three bond types show up on almost every steel project:
- Performance bond—guarantees completion; the surety compensates the owner up to the bonded amount if the contractor walks.
- Advance payment guarantee—backs the 30% advance buyers commonly pay; it releases in step with progress and protects the owner if the supplier disappears.
- Retention bond—replaces the 5%–10% cash retention owners usually hold, freeing the contractor's working capital.
Bonds can be issued by banks or by surety/insurance companies. Bank guarantees tend to be stricter on collateral but are accepted everywhere; surety bonds are often faster to arrange. For how bonds interact with your payment schedule and retention, see steel building payment milestones; where letters of credit sit alongside bonds, read steel building letter of credit. For the full mechanics of a steel building performance bond—bond amount, claim process, forfeiture triggers, and how it differs from an advance-payment guarantee or a retention bond—our dedicated guide walks through the surety documents, typical pricing, and the project types where it is mandatory. For the advance payment guarantee in particular—how it amortizes as work progresses, typical percentage, validity period, and the difference between on-demand and conditional guarantees—see our advance payment guarantee explainer. Where delay pushes completion past the contractual date, accrued liquidated damages are commonly deducted from the same retention or progress payments. For the daily LD rate, the 5–10% cap, and the EOT notice window that stops the LD clock, see our steel building liquidated damages and delay claims guide.
Table 3: Common Bonds for Steel Projects
| Bond Type | Beneficiary | Typical Amount | Cost Range |
|---|---|---|---|
| Performance bond | Owner | 5%–10% of contract | 0.5%–2% / year of bonded amount |
| Advance payment guarantee | Owner | Equal to advance (e.g., 30%) | 0.5%–1.5% / year, amortizes with progress |
| Retention bond | Owner | 5%–10% of contract | 0.5%–1.5% / year |
Typical ranges; surety pricing depends heavily on contractor credit and country risk.
Claims Process — What to Do When Loss Happens
A policy only pays if you handle the loss correctly. The construction insurance claims process starts within hours, not weeks.
Within 24 hours, do four things: (1) send written notice of loss to the insurer; (2) preserve the scene and photograph everything—do not rush to clear it; (3) if a third party (neighbor, pedestrian) is hurt or property is damaged, call the police or local authority immediately; and (4) appoint an independent surveyor (SGS, BV, or equivalent) if the loss is material.
Then assemble the claims file: the policy, invoices and contract, packing list and transport documents, the independent survey report, at least two repair/replacement quotations, and an engineering report explaining the cause. Documentation that starts on day one settles faster and higher.
The most common reasons claims are rejected are boring, not dramatic: late notice, a breach of a policy condition (e.g., erecting outside the approved method), self-inflicted loss, or a claim below the deductible. Small losses typically settle in 30–90 days; major losses with subrogation can take 6–18 months. For the records that make or break a claim, our site acceptance inspection checklist and third-party inspection evidence are your best allies.
Table 4: Typical Claims Timeline & Required Documents
| Stage | Timeline | Documents Required |
|---|---|---|
| Notice of loss | Within 24 hours | Written notice, photos of scene |
| Survey | 3–10 days | Independent surveyor report (SGS/BV) |
| Claim submission | 2–4 weeks | Policy, invoices, contract, packing list, B/L |
| Valuation | 4–12 weeks | Two repair/replacement quotations, cause report |
| Settlement | 30–90 days (small) / 6–18 months (large) | Signed discharge, payment |
Illustrative timeline; adjust to your policy and local survey market.

Delayed Start-Up & Third-Party Liability
For plants where every day of delay costs real money, the construction stack needs one more layer: delayed start-up insurance (DSU / Delay in Start-Up). DSU covers the lost profit a construction accident causes when the plant cannot open on time. It is most relevant to power plants, factories, and logistics parks where the daily revenue forecast is known. The sum insured is roughly expected daily profit × estimated delay days, and it is bought as an extension to the CAR/EAR policy.
Two further extensions round out the program:
- Third-party liability (TPL)—covers damage to adjacent property or injury to outsiders caused during construction. It is usually attached to CAR/EAR rather than bought separately.
- Employer's liability—covers injury or death of site workers. Owners routinely demand a valid copy of the contractor's policy before work starts.
On cost, a typical steel building insurance budget runs: CAR/EAR premium about 0.3%–0.8% of contract value, DSU a further 0.1%–0.3%, and performance-bond fees 0.5%–2% per year. These are typical industry ranges; confirm with your broker, because risk, geography, and claim history move them around.
Table 5: Indicative Insurance Cost Stack
| Coverage | Typical Cost (% of Contract) | When to Buy |
|---|---|---|
| CAR / EAR all risks | 0.3%–0.8% | Before first column arrives on site |
| Marine cargo | 0.1%–0.3% of cargo value | Before vessel loading |
| DSU (delay in start-up) | 0.1%–0.3% | With the CAR/EAR policy |
| Performance bond | 0.5%–2% per year | At contract award |
| TPL / employer's liability | Within CAR/EAR package | With construction cover |
Typical, not quoted; confirm every rate with your broker and surety.
Beyond physical damage and bonds, cross-border steel projects face a third risk layer: contract-defined events that excuse performance entirely. Our steel building force majeure notice guide explains which events qualify (port closures, pandemics, war), the 14-day evidence requirement, and how CAR insurance interacts with force-majeure suspension when site erection stops.
Practical Tips for Buyers
Three buying habits separate owners who are properly covered from those who discover gaps after a loss.
Buy at the right moment. CAR/EAR must be in force before the first steel column arrives on site, and cargo cover must attach before loading. Back-dated policies are almost impossible to place.
Negotiate who pays the premium. Owners often fold the premium into the contract price. If you buy CIF, the seller arranges cover on your behalf—check the policy names you as beneficiary and that the clauses are A, not the minimum C.
Name the right loss payee. Where a letter of credit is used, the bank or owner is often listed as loss payee so settlement follows the financing. Get this right or the claim money may go somewhere other than you. For the clause-level detail, our steel building contract review and steel building quote breakdown guides show where these obligations sit.
Conclusion
A complete steel building insurance program is a stack, not a single policy: CAR or EAR during construction, marine cargo for the voyage, a performance bond against non-performance, and DSU for revenue at risk. Your Incoterms decide who buys the cargo cover; the contract template decides who buys the builder's risk cover. When loss strikes, a written notice within 24 hours and a clean contemporaneous file—photos, surveyor report, invoices—are what turn a claim into a payout rather than a denial. Treat a steel building insurance program as a risk stack to be designed, not an afterthought to be bought.

Case Example
A 15,000 m² (≈161,000 sq ft) light-industrial plant was imported in knocked-down form from an Asian fabricator under an FOB contract. During the ocean leg, two containers—carrying roughly 18% of the column tonnage—were lost overboard in a storm. The owner's early paperwork covered only supplier-side risk.
Key challenges: a coverage gap between factory, sea, and site erection, plus a tight schedule that could not absorb a long dispute.
Solution: the project was layered with Construction All Risks cover during erection, marine cargo insurance on the voyage, and a 10% performance bond against non-delivery. Claims were filed within the contractual notice window with packing lists, BL data, and GPS/vessel AIS records attached.
Results: about 92% of the lost steel value was recovered from the marine cargo policy, the replacement columns were re-cut within three weeks, and overall schedule slipped only four weeks rather than the twelve first feared. See performance bond and payment milestones for the contract-side mechanics that made the claim airtight.

Frequently Asked Questions
Q1: What is CAR insurance for a steel building?
A: Construction All Risks (CAR) insurance covers the whole project during building—fire, flood, storm, construction errors, and third-party damage. It typically names both owner and contractor as insured, and the sum insured equals the contract value plus freight and duties.
Q2: What is the difference between CAR and EAR?
A: CAR covers the whole construction phase; EAR (Erection All Risks) focuses specifically on the lifting and installation stage—collapsed columns, component collisions, installation-related damage. Steel-frame projects often use EAR, or a CAR policy that includes erection.
Q3: Do I need cargo insurance for imported steel?
A: Yes, especially if you buy CIF/CIP where the seller arranges cover—check that your company is the loss payee. Under FOB/FCA you arrange cover yourself. Institute Cargo Clauses A (all risks) is the usual choice; war and strikes are usually added.
Q4: What is a performance bond?
A: A performance bond is a bank or insurer guarantee paid to the owner—typically 5–10% of contract value. If the contractor fails to perform, the surety pays up. It is common on EPC and government projects and costs roughly 0.5–2% per year of the bonded amount.
Q5: How do I make a successful insurance claim?
A: Notify the insurer in writing within 24 hours, preserve the scene and photos, gather the policy, invoices, packing list, transport documents, and an independent survey report. Settle with at least two repair quotations. Missing the notice window or violating policy conditions are the two most common reasons claims are rejected.
