Key Differences in Builders Risk Insurance

What property is scheduled

The property page cited in Marsh’s record, read 2026-09-23, is published by Marsh McLennan Agency (MMA), which describes builders-risk protection for additions, foundations, temporary structures, and insured-owned materials, with limited treatment of others’ materials. This is MMA’s middle-market practice, not a separately branded Marsh product. CNA’s brochure describes construction-project damage with natural disaster, vandalism, and theft examples. Ask the Marsh contact to identify the placing entity and compare how both forms treat subcontractor materials. 10 5

Advisor placement and risk review

MMA says its property practice offers hazard assessment, valuation, catastrophe modeling, risk control, program design, and claims advocacy. CNA’s reviewed builders-risk record does not describe comparable advisory services. Ask the MMA contact which services apply to a construction placement and ask CNA whether project risk-control or valuation support is available. 10 4
