Key Differences in Builders Risk Insurance

Extensions and Optional Endorsements

AIG describes tailoring a project extension after a standstill. Nationwide lists optional endorsements for debris removal, earthquake, flood, and business income alongside property under construction, materials, and temporary structures. These features answer different questions: ask AIG about the schedule change and ask Nationwide which optional coverages are available and priced for the site. 3 7

Risk Services and Submission Route

AIG says its risk engineers can prepare loss-control reports and prevention plans. Nationwide directs buyers to an agent or quote request but does not detail a builders risk engineering service in the reviewed offering. If risk advice matters to the project, ask AIG what work is available and ask Nationwide who would handle risk recommendations and site concerns. 3 7

What to Confirm in Builders Risk Insurance Quotes

  • Ask Nationwide which of the listed optional endorsements can be added to your quote and ask AIG to specify the terms of any standstill extension. 3 7
  • Request the agent or underwriter who will answer Nationwide coverage questions and the AIG risk-engineering scope. 3 7
  • Compare the underlying forms, values, deductibles, and exclusions rather than endorsement labels alone. 3 7
