## Research Scope and Use

Use this comparison to evaluate Chubb and Harper for Builders Risk Insurance against the same documented criteria. It identifies differences and questions to confirm; it does not select a winner for a particular business. Offering claims are what each provider publishes about this line unless marked otherwise. “Not found” describes the evidence reviewed, not proof that a feature is unavailable. Confirm the insurer, policy wording, limits, retentions, exclusions and cost in an actual quote.

## Summary

Chubb underwrites Individual Project and Master Program builders’ risk, including delay-in-opening, DIC and international cover. Harper brokers builders risk as part of Construction & Contractors insurance, quoting one application across construction markets and issuing additional-insured certificates the same day a contract requires them.

## 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.

## What Is Builders Risk Insurance?

Builders risk insurance addresses physical property losses during building construction. [9](https://content.naic.org/glossary-insurance-terms "Glossary of Insurance Terms")

## Key Differences in Builders Risk Insurance

### Carrier Versus Construction-Package Broker

Chubb underwrites builders’ risk directly. Harper places builders risk as one piece of its Construction & Contractors package, calling every market that writes construction and presenting options rather than underwriting. Harper’s reviewed pages do not name those markets. [4](https://www.chubb.com/us-en/business-insurance/builders-risk-insurance.html "Builders' Risk Insurance") [7](https://www.harperinsure.com/industries/construction-insurance "Construction & Contractors Insurance")

### Engineering Projects Versus Trades Coverage Callouts

Chubb targets contractors, developers, owners or homebuilders with an active construction program and writes commercial, residential and engineering construction such as bridges and tunnels, with master programs, delay-in-opening, DIC, green endorsements and contract-penalty cover. Harper describes builders risk as covering structure, materials and fixtures from ground break to handover for GCs, specialty trades, remodelers, residential and commercial builders and construction managers, alongside jobsite liability. [4](https://www.chubb.com/us-en/business-insurance/builders-risk-insurance.html "Builders' Risk Insurance") [7](https://www.harperinsure.com/industries/construction-insurance "Construction & Contractors Insurance") [8](https://www.harperinsure.com/ "Harper Homepage")

### Submissions, Certificates and Consulting

Chubb lists submission requirements including values, locations and delay-in-opening details, and offers loss-control consulting bundled or unbundled. Harper says it takes one application for construction risk, quotes admitted and excess-and-surplus markets, and writes additional-insured, waiver-of-subrogation and primary-and-non-contributory certificates the same day. Neither publishes builders-risk dollar limits. [4](https://www.chubb.com/us-en/business-insurance/builders-risk-insurance.html "Builders' Risk Insurance") [7](https://www.harperinsure.com/industries/construction-insurance "Construction & Contractors Insurance")

## What to Confirm in Builders Risk Insurance Quotes

- Ask Harper whether Chubb is among the construction markets it quotes and whether delay-in-opening is available. [7](https://www.harperinsure.com/industries/construction-insurance "Construction & Contractors Insurance") [4](https://www.chubb.com/us-en/business-insurance/builders-risk-insurance.html "Builders' Risk Insurance")
- Ask Chubb whether the account needs an individual project policy or a master program. [4](https://www.chubb.com/us-en/business-insurance/builders-risk-insurance.html "Builders' Risk Insurance")
- Confirm certificate wording and timing if the contract requires same-day AI/waiver language. [7](https://www.harperinsure.com/industries/construction-insurance "Construction & Contractors Insurance")
- If the work is a bridge, tunnel or other engineering job, ask whether Harper’s trades package or Chubb’s engineering construction appetite is the intended path. [4](https://www.chubb.com/us-en/business-insurance/builders-risk-insurance.html "Builders' Risk Insurance") [7](https://www.harperinsure.com/industries/construction-insurance "Construction & Contractors Insurance")

[7](https://www.harperinsure.com/industries/construction-insurance "Construction & Contractors Insurance") (Evidence: Not publicly disclosed; scope: Checked the Construction & Contractors industry page and homepage industries carousel on 2026-09-23; a specific insurer would appear on the quote or policy..) |

| Limits and Retentions | Chubb says it offers capacity in a variety of positions, including primary, full limit, quota share, buffer and excess layer, but the reviewed page does not publish specific dollar limits. [4](https://www.chubb.com/us-en/business-insurance/builders-risk-insurance.html "Builders' Risk Insurance") (Evidence: Not found in reviewed sources; scope: Coverage list and Benefits section..) | Harper's reviewed pages do not publish builders risk limits, deductibles or maximum project values; the industry page says cost depends on trade, payroll and revenue and is quoted individually across multiple markets.

[4](https://www.chubb.com/us-en/business-insurance/builders-risk-insurance.html "Builders' Risk Insurance") (Evidence: Company-reported; scope: Coverage list Benefits section..) | Harper says it writes certificates of insurance with additional-insured, waiver-of-subrogation and primary-and-non-contributory wording the same day a contract calls for it, and checks subcontractors' certificates so their risk does not become the general contractor's. [7](https://www.harperinsure.com/industries/construction-insurance "Construction & Contractors Insurance") (Evidence: Company-reported; scope: Construction & Contractors industry page; describes the certificate and risk-review service Harper says it provides around construction projects, which includes builders risk jobs..) |
| How to Apply | Chubb says submissions should include a project description, statement of values, locations, limits and coverage requirements, plus a breakdown of soft costs, pro forma and period of indemnity if delay-in-opening coverage is requested. [4](https://www.chubb.com/us-en/business-insurance/builders-risk-insurance.html "Builders' Risk Insurance") (Evidence: Company-reported; scope: Submission requirements section..) | Harper says it takes one application for construction risk, including builders risk, and quotes it across every market it says writes construction, admitted where pricing allows and excess-and-surplus lines when the work demands it. [7](https://www.harperinsure.com/industries/construction-insurance "Construction & Contractors Insurance") (Evidence: Company-reported; scope: Construction & Contractors industry page 'Why Harper' section; specific markets contacted for a given project are not named..) |
