What Is Builders Risk Insurance?
Builders risk protects the project you are building, including materials meant for it, against physical loss until construction ends. The gaps that cost owners money are materials in storage or transit, the existing building in a renovation, and coverage ending when you occupy early. 10,11,12,13
What Are the Key Differences Between Aon and Berkshire Hathaway Specialty Insurance Builders Risk Insurance?
Testing, Delay, and Soft Costs
Berkshire Hathaway Specialty Insurance specifically lists hot testing and commissioning, delay, and soft-cost features in its Builder’s Risk description. Aon describes construction property protection for accidental damage to project property or materials, without naming those features in the reviewed line record. A buyer whose schedule includes commissioning or whose financing depends on a timely opening should ask which testing phases and delay costs the proposed wording addresses; a general construction-property description does not resolve them. 8 3
Placement and Project Review
The two records also describe different placement conversations. Aon emphasizes project risk advice and a global broking network; Berkshire Hathaway Specialty Insurance lists primary and excess placements, single-peril and difference-in-conditions options, and says underwriting may request project details, contractor loss history, and a construction schedule. That gives buyers concrete form and submission points to settle early, while the broker’s selected insurer and participation remain quote-specific. 3 8 9

Aon vs Berkshire Hathaway Specialty Insurance: Builders Risk Insurance: documented features by provider
| Criteria | Aon Builders Risk brokerage and risk-advisory offering | Builder’s Risk |
|---|---|---|
| Role in This Line | Aon says its global construction practice designs and places risk solutions and uses broking experience and a global network across construction insurance lines. For builders risk, this is evidence of Aon’s brokered market offering; the page does not identify the insurer for a buyer’s placement. 3Company-reported. Aon’s global construction and infrastructure practice page. This establishes a marketed brokerage/advisory offering, not policy issuance or account-specific placement. | BHSI describes primary and excess options for its Builder’s Risk products, along with single-peril and difference-in-conditions choices. 8Company-reported. These are marketed placement options, not a commitment to provide any layer or a statement about how a specific project is insured. |
| Issuing Insurer | The reviewed practice page does not name the insurer or producing legal entity for a specific placement. Ask for both on the quote and binder. 3Not found in reviewed sources. Aon’s global practice page as reviewed 2026-09-30; no state-specific placement schedule or buyer quote was reviewed. This does not establish that Aon cannot arrange a placement. | Confirm in your quote. |
| Who It’s For | Aon describes its global construction and infrastructure practice as serving contractors, owners, developers, engineers, architects, designers, financiers and investors, and says it works with organizations of varied sizes and complexity. 3Company-reported. Audience described for Aon’s global construction and infrastructure practice. It does not establish U.S. state availability or underwriting eligibility for a placement. | BHSI separates its EAR and CAR target categories; it says Master Builder’s Risk is considered selectively. 8Company-reported. The published target categories guide submission discussions; they do not guarantee eligibility or acceptance. |
| Coverage Features | Aon lists Builders Risk under construction property and says its construction property offering can address accidental damage to project property or materials during construction and operations. That is a broker’s description of the line, not a grant of coverage for a buyer. 3Company-reported. Aon’s marketing description of the brokerage/coverage area. The page is not the insurer’s policy form and does not establish an insured's entitlement to coverage. | BHSI describes Builder’s Risk as project property coverage and lists hot testing/commissioning, delay and soft-cost features. 8Company-reported. U.S. product-page marketing summary; does not establish that each extension is included in every project policy. The page describes primary and excess placements and single-peril or difference-in-conditions options alongside its all-risk product description. 8Company-reported. These are marketed options, not a statement that a particular quote includes them. BHSI lists its Builder’s Risk Form, follow-form quota-share or excess forms, and broker manuscript forms as options. 9Company-reported. A form being listed does not establish that it will be used for a project or what its final terms contain. |
| Limits and Retentions | The reviewed page does not state a buyer-specific limit, retention, deductible or other placement terms. Confirm these in the quote, bond or issued policy. 3Not publicly disclosed. Aon’s global practice page as reviewed 2026-09-30; no quote, bond form or issued policy was reviewed. | Confirm in your quote. |
| Risk Services | Aon describes project risk-advisory services to understand project-specific risks and develop risk-transfer, management or mitigation strategies. It also describes a global construction team and market access. These are company-reported brokerage and advisory services, not coverage benefits. 3Company-reported. Company-reported advisory services on Aon’s global practice page; account-specific service scope is not stated. | Confirm in your quote. |
| How to Apply | Confirm in your quote. | BHSI says underwriting may request coverage specifications, a project description, contractor loss experience and a construction schedule, among other project details. 9Company-reported. The guide gives examples rather than a universal or complete checklist; requirements depend on the submission. |
