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 Aon and Nationwide Builders Risk Insurance?

Endorsements and Scheduled Property

Nationwide describes property under construction, construction materials, and temporary structures, and lists possible endorsements for debris removal, earthquake, flood, and business income. Aon’s record describes accidental damage to project property or materials but does not enumerate those options. Buyers with catastrophe exposure or delay costs should ask which endorsements are available, their sublimits and triggers, and whether temporary structures are valued separately. A listed option is not a promise that it applies to a particular risk. 7 3

Route to a Quote

Nationwide directs prospective buyers to an agent or quote request. Aon describes a brokered construction practice and project-specific advice. The difference is a stated carrier-facing agent route versus a broader broker engagement; neither description guarantees issuance or timing. Provide the same project schedule, locations, values, and soft-cost estimate to both channels so the indications can be compared on equivalent terms. 7 3
