## Aon vs Zurich U.S. Builders Risk Insurance Summary

Zurich U.S. describes physical-loss protection during construction, renovation, or installation and lists flood and soft costs as potential options. Aon describes accidental damage to project property or materials during construction and operations. [3](https://www.aon.com/en/capabilities/risk-transfer/construction-and-infrastructure-insurance-and-risk-management "Construction and Infrastructure Insurance and Risk Management") [6](https://www.zurichna.com/insurance/zpm/construction/commercial "Commercial Builders Risk Program | Zurich Insurance")

## What Is Aon?

Aon’s U.S. Commercial Risk terms describe brokerage for certain insurance programs, while its Middle Market page describes a dedicated practice for mid-sized organizations across North America. The public materials reviewed do not identify the licensed producer or insurer for a particular placement. Ask which entity will produce each line and which insurer will issue the policy; request jurisdiction details for the proposed placement and ask how compensation and claim notice work for your account. [1](https://www.aon.com/en/about/leadership-and-governance/brokerage-terms-of-service-for-commercial-risk-solutions-us "Commercial Risk Solutions U.S. Brokerage Terms of Service") [2](https://www.aon.com/en/capabilities/middle-market-clients "Middle Market Clients")

## Zurich U.S. Business Insurance: Products, Access, and Claims

Zurich U.S. serves Middle Market businesses and large or national accounts with commercial property-casualty and specialty insurance. Buyers can explore product lines and work through an agent or broker; the insurer named on a quote or policy identifies which Zurich company underwrites that coverage.

## 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. [7](https://content.naic.org/glossary-insurance-terms "Glossary of Insurance Terms") [8](https://www.insurance.ca.gov/01-consumers/105-type/95-guides/09-comm/commercialguide.cfm "Commercial Insurance Guide") [9](https://assets.touchpointmarkets.com/e8/58/dec27c1b462c8227b4693fb8ac81/ih-00-70-05-17-builders-risk-coverage-form.pdf "Builders Risk Coverage Form") [10](https://go.usassure.com/rs/381-ISO-510/images/us-assure-builders-risk-application-tip-sheet.pdf "Builders Risk Application Tip Sheet")

## What Are the Key Differences Between Aon and Zurich U.S. Builders Risk Insurance?

### Published Program Appetite

Zurich U.S. describes a commercial builders-risk program for physical loss during construction, renovation, or installation, lists water and sewer pipelines within appetite, and names oil and gas pipelines, tunnels, dams, and certain other project types as ineligible. Aon’s record describes a broader construction practice but gives no comparable project exclusion list. Buyers should test the actual project against Zurich U.S.’s stated boundaries and ask Aon which markets will consider any excluded class. [6](https://www.zurichna.com/insurance/zpm/construction/commercial "Commercial Builders Risk Program | Zurich Insurance") [3](https://www.aon.com/en/capabilities/risk-transfer/construction-and-infrastructure-insurance-and-risk-management "Construction and Infrastructure Insurance and Risk Management")

### Project Limits and Options

Zurich U.S.’s page has conflicting project-value descriptions: some sections say up to $75 million while another refers to projects of any size and value. These are project values, not policy limits. The same page lists potential flood, earth-movement, soft-cost, business-income, and testing options. Aon describes project risk advice without publishing project-specific limits. Confirm Zurich’s current eligibility and each extension in the quote. [6](https://www.zurichna.com/insurance/zpm/construction/commercial "Commercial Builders Risk Program | Zurich Insurance") [3](https://www.aon.com/en/capabilities/risk-transfer/construction-and-infrastructure-insurance-and-risk-management "Construction and Infrastructure Insurance and Risk Management")

## What Should You Confirm in Aon and Zurich U.S. Builders Risk Insurance Quotes?

- Does the project’s value fall within Zurich U.S.’s underwriting appetite, given the conflicting published thresholds? [3](https://www.aon.com/en/capabilities/risk-transfer/construction-and-infrastructure-insurance-and-risk-management "Construction and Infrastructure Insurance and Risk Management") [6](https://www.zurichna.com/insurance/zpm/construction/commercial "Commercial Builders Risk Program | Zurich Insurance")
- Which named exclusions, testing terms, and soft-cost or catastrophe extensions appear in the actual quote? [3](https://www.aon.com/en/capabilities/risk-transfer/construction-and-infrastructure-insurance-and-risk-management "Construction and Infrastructure Insurance and Risk Management") [6](https://www.zurichna.com/insurance/zpm/construction/commercial "Commercial Builders Risk Program | Zurich Insurance")

| Risk Services | Aon describes project risk-advisory services to understand project-specific risks and develop risk-transfer, management or mitigation strategies. It also describes a global construction team and market access. These are company-reported brokerage and advisory services, not coverage benefits.

Public ratings for Aon are low: Trustpilot shows 1.2 out of 5 from 782 reviews, and BBB shows 1.6 from five. Aon is a global firm, so those pages mostly reflect other parts of the business, not large U.S. commercial accounts.
