## 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. [12](https://content.naic.org/glossary-insurance-terms "Glossary of Insurance Terms") [13](https://www.insurance.ca.gov/01-consumers/105-type/95-guides/09-comm/commercialguide.cfm "Commercial Insurance Guide") [14](https://assets.touchpointmarkets.com/e8/58/dec27c1b462c8227b4693fb8ac81/ih-00-70-05-17-builders-risk-coverage-form.pdf "Builders Risk Coverage Form") [15](https://go.usassure.com/rs/381-ISO-510/images/us-assure-builders-risk-application-tip-sheet.pdf "Builders Risk Application Tip Sheet")

## What Are the Key Differences Between Berkshire Hathaway Specialty Insurance and CNA Builders Risk Insurance?

### Construction Property and Marine Classification

CNA lists Builders Risk under inland marine and gives theft, vandalism and natural-disaster damage as examples of construction property exposures. It separately lists Hull Builders Risk under ocean marine. Berkshire Hathaway Specialty Insurance describes project property cover and a range of all-risk or single-peril structures. If the project includes a vessel or marine construction element, CNA’s separate category makes it important to identify whether the exposure is hull or land-based project property. [10](https://www.cna.com/products/marine "Inland & Ocean Marine Insurance") [5](https://www.bhspecialty.com/us-products/us-builders-risk/ "Builder’s Risk")

### Layers and Delay Features

Berkshire Hathaway Specialty Insurance lists primary and excess placements and names delay and soft-cost features. CNA’s reviewed marine materials describe the Builders Risk category and example property damage, but do not specify layers or delay coverage. A buyer comparing a project with financing or completion-cost exposure should ask CNA for the available form and ask BHSI for the applicable delay trigger and sublimit. [5](https://www.bhspecialty.com/us-products/us-builders-risk/ "Builder’s Risk") [11](https://www.cna.com/sites/default/files/assets/marine-capabilities-brochure.pdf "Marine Capabilities Brochure")

### Separate the Scope in the Submission

CNA distinguishes inland Builders Risk from ocean Hull Builders Risk; Berkshire Hathaway Specialty Insurance separates engineering and construction target categories and considers Master Builder’s Risk selectively. Describe the project’s land-based work, marine equipment and construction phases in the submission so the proposed class and schedule match the exposures. [10](https://www.cna.com/products/marine "Inland & Ocean Marine Insurance") [6](https://www.bhspecialty.com/wp-content/uploads/marketing/Builders-Risk-Appetite-Guide-US.pdf "Builder’s Risk Appetite Guide")

## What Should You Confirm in Berkshire Hathaway Specialty Insurance and CNA Builders Risk Insurance Quotes?

- For CNA, is the project being quoted as inland Builders Risk, Hull Builders Risk, or both? [10](https://www.cna.com/products/marine "Inland & Ocean Marine Insurance")
- For BHSI, what delay or soft-cost coverage, trigger and sublimit appear in the proposed form? [5](https://www.bhspecialty.com/us-products/us-builders-risk/ "Builder’s Risk")
- Do the project schedule and stated engineering/construction class fit the selected insurer’s appetite? [6](https://www.bhspecialty.com/wp-content/uploads/marketing/Builders-Risk-Appetite-Guide-US.pdf "Builder’s Risk Appetite Guide")

| How to Apply | BHSI says underwriting may request coverage specifications, a project description, contractor loss experience and a construction schedule, among other project details. [6](https://www.bhspecialty.com/wp-content/uploads/marketing/Builders-Risk-Appetite-Guide-US.pdf "Builder’s Risk Appetite Guide") (Evidence: Company-reported; scope: The guide gives examples rather than a universal or complete checklist; requirements depend on the submission..) | Confirm in your quote. |
