## Alliance Risk vs Marsh Builders Risk Insurance Summary

Alliance Risk lists off-site inland marine and OCIP/CCIP wraps; Marsh McLennan Agency covers additions, foundations and temporary structures within its property practice, including others’ materials on a limited basis. [1](https://joinalliancerisk.com/builders-risk-insurance/ "Builders Risk Insurance") [2](https://joinalliancerisk.com/coverages/ "Alliance Products") [3](https://www.marshmma.com/us/solutions/property.html "Property Insurance")

## What Are the Key Differences Between Alliance Risk and Marsh Builders Risk Insurance?

### Dedicated Project Page Versus Property Practice

MMA describes builders risk for additions, foundations, temporary structures, and materials owned by you; materials belonging to others are included only on a limited basis. Alliance Risk explicitly lists tools, machinery and materials in transit or off-site plus wrap-up structures. [3](https://www.marshmma.com/us/solutions/property.html "Property Insurance") [1](https://joinalliancerisk.com/builders-risk-insurance/ "Builders Risk Insurance")

### What the Coverage Descriptions Include

Alliance Risk bundles inland marine for tools, machinery and materials in transit or stored off-site and supports OCIP, CCIP and wrap-ups. MMA says builders’ risk addresses risks unique to a building under construction, including additions and alterations, foundations, temporary structures, and materials and supplies owned by the insured, and on a limited basis materials belonging to others. [1](https://joinalliancerisk.com/builders-risk-insurance/ "Builders Risk Insurance") [3](https://www.marshmma.com/us/solutions/property.html "Property Insurance")

### Services Around the Policy

Alliance Risk describes project benchmarking with owner, developer and contractor and a construction claims team through closeout. MMA’s property practice lists hazard assessment and valuation, loss and catastrophe modeling, claims advocacy, pre- and post-loss risk control, and program design from global market experience—services described for property generally, not exclusively for builders’ risk. You work with an MMA property specialist; Alliance Risk’s page is a product-line consultation path. Neither names the issuing insurer.
