Chubb vs 
Marsh Builders Risk Insurance
Chubb underwrites named builders-risk programs; Marsh McLennan Agency places the line inside a broader property practice.
What Is Chubb?
Chubb is the marketing name for a global insurance group whose U.S. companies underwrite commercial property, casualty, cyber and financial-lines coverage, including technology-focused DigiTech ERM and small-business packages. Founders and finance teams typically work through an appointed agent, then receive a policy issued by a named Chubb-group insurer rather than by the Swiss holding company. 1,2,3
What Is Marsh?
Marsh is a global insurance broker and risk advisor. In the United States it places coverage through core Marsh teams and through Marsh McLennan Agency for many middle-market buyers, including technology, cyber, property, casualty and benefits programs. 5,6,7,8
What Is Builders Risk Insurance?
Builders risk insurance addresses physical property losses during building construction. 10
Key Differences in Builders Risk Insurance
Who Writes the Policy
Chubb underwrites builders' risk itself. Marsh McLennan Agency (MMA), Marsh’s middle-market subsidiary, places the coverage through its property practice and does not issue the policy. The practical distinction is a Chubb-underwritten placement versus an MMA placement whose issuing insurer is not named on the reviewed page; neither marketing description establishes that its policy form is broader for a particular project. 4 9
What Delay and Soft Costs Look Like
Chubb lists delay-in-opening and asks for a soft-cost breakdown, pro forma and period of indemnity when that cover is requested. MMA’s builders’ risk subsection talks about a building under construction—additions, foundations, temporary structures and materials—but does not describe delay-in-opening as a named option. You would need the MMA quote to see whether time-element cover is even on the form. 4 9
Materials and Who Owns Them
MMA says coverage can include, on a limited basis, materials and supplies belonging to others as well as those the insured owns. Chubb’s reviewed page names physical-damage and related program types but does not spell out that “others’ materials” treatment. A quote should show whether suppliers’ or subcontractors’ goods on site are insured. 9 4
How You Start a Submission
Chubb wants a project description, statement of values, locations, limits and coverage requirements. MMA says you work with a property specialist and names a National Accounts Property Practice Leader; it does not describe an online quote. The Chubb path is a documented underwriting file; the MMA path is an advisor-led placement. 4 9
What to Confirm in Builders Risk Insurance Quotes
- Ask Chubb whether delay-in-opening is on the quote, and ask MMA which insurer would issue the layer. 4 9
- Check how each form treats materials belonging to others. 9 4
- Ask whether MMA’s property-practice modeling and claims advocacy attach to this job, and whether Chubb’s loss-control is bundled or unbundled. 9 4
- Get written limits; neither reviewed page publishes dollar figures. 4 9
