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. 10,11,12,13
Key Differences in Builders Risk Insurance
Property Scope and Endorsements
Marsh McLennan Agency describes builders-risk protection for additions and alterations, foundations, temporary structures, and materials owned by the insured; materials owned by others are described as covered on a limited basis. Nationwide's overview lists property under construction, materials, and temporary structures, with options such as debris removal, flood, earthquake, and business income. A project using owner-furnished or contractor-owned supplies should get the ownership distinction spelled out in both schedules. 5 9
Property Risk and Claims Resources
Marsh describes hazard assessment and valuation, loss and catastrophe modeling, risk control before and after a loss, and claims advocacy through its property practice. Nationwide's product overview identifies its construction offering and endorsements but does not describe those advisory services. If your project needs catastrophe analysis or claims support, ask Marsh what is included in the placement and ask Nationwide's agent what services accompany the quoted policy. 5 9
