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. 8,9,10,11
What Are the Key Differences Between Liberty Mutual and Markel Insurance Builders Risk Insurance?
Long Project Periods and Capacity
Markel says its builders-risk coverage periods may extend up to 60 months and that it may write 100% of a risk or participate as a subscriber; project-specific capacity still needs confirmation. Liberty Mutual's public overview does not establish a general policy period, limit, or deductible. For a multi-year build or a project that may need layered capacity, Markel's published parameters give you specific questions to take to both quotes. 7 4
Building Projects and Infrastructure
Liberty Mutual describes projects ranging from buildings to infrastructure and addresses contractors and property owners with single projects or portfolios. Markel identifies exposures from basic four-wall risks through complex civil and mechanical engineering, including bridges, dams, tunnels, and power facilities. If the project involves infrastructure or specialized engineering, provide the same construction stages and values to each underwriter; the public descriptions do not establish acceptance of a specific risk. 3 7
