## 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. [7](https://content.naic.org/glossary-insurance-terms "Glossary of Insurance Terms") [8](https://www.insurance.ca.gov/01-consumers/105-type/95-guides/09-comm/commercialguide.cfm "Commercial Insurance Guide") [9](https://assets.touchpointmarkets.com/e8/58/dec27c1b462c8227b4693fb8ac81/ih-00-70-05-17-builders-risk-coverage-form.pdf "Builders Risk Coverage Form") [10](https://go.usassure.com/rs/381-ISO-510/images/us-assure-builders-risk-application-tip-sheet.pdf "Builders Risk Application Tip Sheet")

## Key Differences in Builders Risk Insurance

### Published Project Scope

Markel names civil and mechanical engineering and completed civil projects including bridges, dams, tunnels and power facilities. Marsh McLennan Agency (MMA) describes a Builders’ Risk Panel for construction or renovation and lists fire, theft, vandalism and natural disasters as example risks. The descriptions give buyers different starting points: infrastructure owners can test their project against Markel’s examples, while MMA can discuss the panel’s fit for a construction or renovation exposure. [3](https://www.markel.com/us/industries/construction/large-builders-risk "Builders Risk Insurance") [6](https://www.marshmma.com/us/industries/construction.html "Construction Insurance | MMA")

### Duration and Capacity

Markel states periods may extend up to 60 months and says it may write 100% or participate as a subscriber, subject to project-specific capacity. MMA’s reviewed panel overview does not set a universal period, limit or retention. Ask Markel for the exact participation share and ask MMA to identify the panel insurer and provide the project’s quoted limits and term; those details determine whether either placement matches the build schedule. [3](https://www.markel.com/us/industries/construction/large-builders-risk "Builders Risk Insurance") [6](https://www.marshmma.com/us/industries/construction.html "Construction Insurance | MMA")

### Application Route

MMA invites organizations to contact an adviser or specialist to discuss placement. Markel’s record describes coverage capability and capacity but does not establish a direct online quote flow. If you need a proposal for a construction deadline, ask each team what drawings, values, contracts and schedule it needs, and when a bound policy could take effect. [6](https://www.marshmma.com/us/industries/construction.html "Construction Insurance | MMA") [3](https://www.markel.com/us/industries/construction/large-builders-risk "Builders Risk Insurance")

## What to Confirm in Builders Risk Insurance Quotes

- Ask MMA which panel insurer is proposed and request the form, limits, retentions, exclusions and conditions. [6](https://www.marshmma.com/us/industries/construction.html "Construction Insurance | MMA")
- Ask Markel to confirm the actual period and whether it is offering full or shared project capacity. [3](https://www.markel.com/us/industries/construction/large-builders-risk "Builders Risk Insurance")
- Give both teams project values, schedule, construction/renovation scope and requested effective date. [3](https://www.markel.com/us/industries/construction/large-builders-risk "Builders Risk Insurance") [6](https://www.marshmma.com/us/industries/construction.html "Construction Insurance | MMA")
