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

### Property values and covered work

Liberty Mutual’s builders-risk description names materials, labor, construction-management fees, temporary structures, and landscaping materials during construction. CNA’s brochure instead describes property damage to construction projects and gives natural disaster, vandalism, and theft as examples. If the project includes temporary works or landscaping, list their values and ask whether they fall within the proposed insured property definition. [8](https://business.libertymutual.com/commercial-solutions/property/ "Property") [5](https://www.cna.com/sites/default/files/assets/marine-capabilities-brochure.pdf "Marine Capabilities Brochure")

### Project size and risk services

Liberty Mutual describes property underwriting, engineering, and claims teams working together on projects and portfolios that include buildings and infrastructure. The CNA pages reviewed name no corresponding engineering or claims team for Builders Risk. Ask Liberty Mutual which specialists would work on this project; ask CNA whether project engineering or risk-control support can accompany its quote. [9](https://business.libertymutual.com/commercial-solutions/inland-marine/builders-risk "Builder’s risk") [4](https://www.cna.com/products/marine "Inland & Ocean Marine Insurance") [8](https://business.libertymutual.com/commercial-solutions/property/ "Property") [5](https://www.cna.com/sites/default/files/assets/marine-capabilities-brochure.pdf "Marine Capabilities Brochure")

## What Should You Confirm in CNA and Liberty Mutual Builders Risk Insurance Quotes?

- Are temporary structures, landscaping, labor, and soft costs included or subject to sublimits? [5](https://www.cna.com/sites/default/files/assets/marine-capabilities-brochure.pdf "Marine Capabilities Brochure") [8](https://business.libertymutual.com/commercial-solutions/property/ "Property")
- For a portfolio or infrastructure project, what eligibility thresholds and engineering requirements apply?
