## 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. [11](https://content.naic.org/glossary-insurance-terms "Glossary of Insurance Terms") [12](https://www.insurance.ca.gov/01-consumers/105-type/95-guides/09-comm/commercialguide.cfm "Commercial Insurance Guide") [13](https://assets.touchpointmarkets.com/e8/58/dec27c1b462c8227b4693fb8ac81/ih-00-70-05-17-builders-risk-coverage-form.pdf "Builders Risk Coverage Form") [14](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 Liberty Mutual Builders Risk Insurance?

### How each carrier structures the placement

BHSI describes primary and excess positions and single-peril or difference-in-conditions choices for builders risk [5](https://www.bhspecialty.com/us-products/us-builders-risk/ "Builder’s Risk"). Liberty Mutual instead describes a named proprietary form and a stand-alone Specialty Property offering [10](https://business.libertymutual.com/commercial-solutions/inland-marine/builders-risk "Builder’s risk"). If your project needs layered or manuscript wording, BHSI's listed options are more specific on that point; Liberty Mutual's page does not say whether it offers them.

### Project scope and what underwriters ask for

BHSI splits its target classes into EAR and CAR categories, considers Master Builder's Risk selectively, and says underwriting may request a construction schedule and contractor loss experience [6](https://www.bhspecialty.com/wp-content/uploads/marketing/Builders-Risk-Appetite-Guide-US.pdf "Builder’s Risk Appetite Guide"). Liberty Mutual addresses contractors and owners with single projects or portfolios, but its published thresholds apply only to the named program option [10](https://business.libertymutual.com/commercial-solutions/inland-marine/builders-risk "Builder’s risk").

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

- Ask Liberty Mutual which of its two offerings would apply to your project and what limits, deductibles and exclusions come with it [10](https://business.libertymutual.com/commercial-solutions/inland-marine/builders-risk "Builder’s risk").
- Ask BHSI whether your project falls in its EAR or CAR class, and whether a portfolio would be treated as Master Builder's Risk [5](https://www.bhspecialty.com/us-products/us-builders-risk/ "Builder’s Risk").
