Business & Risk Types

Construction Insurance

Construction insurance is the broad category of commercial coverages that protect businesses involved in building, renovating, and maintaining structures and infrastructure. This includes general contractors who manage projects and coordinate subcontractors, specialty trade contractors (electricians, plumbers, framers), developers, and project owners. Construction operations face a concentrated set of high-severity risks — workers falling from heights, heavy equipment damaging neighboring property, completed projects developing defects, and projects stalling due to weather or material failures — that require a multi-layered insurance program to address.

Why Construction Insurance Matters for Independent Agents

Construction is one of the largest commercial insurance segments by premium volume. The U.S. construction industry generates over $2 trillion in annual spending, and construction businesses spend a higher percentage of revenue on insurance than almost any other industry. A general contractor with $5 million in revenue might spend $150,000-$300,000 annually on their total insurance program — GL, workers' comp, commercial auto, builders risk, umbrella, and inland marine. That's a substantial account for any agency.

Construction accounts also tend to be sticky. Switching agents is disruptive for a contractor because the agent becomes embedded in their operations — managing certificates for every project, handling audits, adding and removing subcontractors, and coordinating with project owners who require specific coverage evidence. A contractor who trusts their agent rarely leaves over a modest premium difference.

The complexity of construction insurance is exactly where agents earn their commission. A general contractor needs an agent who understands additional insured requirements, completed operations coverage, wrap-up programs (OCIP/CCIP), subcontractor certificate tracking, and how the workers' comp audit process works for an industry with fluctuating payroll. Direct carriers can't replicate this advisory depth, which is why construction remains one of the most agent-dependent commercial lines segments.

How Construction Insurance Works

A construction insurance program is built in layers, with each coverage addressing a different dimension of risk:

General liability — The foundation coverage for any contractor. Covers third-party bodily injury and property damage arising from the contractor's operations. When a framing crew drops materials onto a parked car below, or a pedestrian is injured by construction debris, GL responds. For construction, GL also includes products-completed operations coverage, which protects against claims arising after the project is finished — a critical exposure since construction defect claims can surface years after completion.

GL pricing for construction depends heavily on the trade classification, annual revenue or payroll, project types, and subcontractor usage. A general contractor who subs out 80% of the work has a different risk profile than one who self-performs most trades. Carriers like Hartford and Progressive ask specifically about subcontractor management — whether the GC requires certificates, additional insured endorsements, and hold-harmless agreements from every sub.

Workers' compensation — Construction has some of the highest workers' comp rates across all industries because the work is inherently dangerous. Classification codes for construction trades range from moderate (painting, averaging around $5-6 per $100 of payroll) to severe (roofing, which can run $10-$30+ per $100 of payroll depending on state; steel erection is among the highest-rated construction codes). For a contractor with $1 million in payroll across multiple trades, workers' comp alone can cost $50,000-$150,000 annually.

Accurate classification is critical. A contractor whose crew performs both carpentry ($8-12 per $100) and roofing ($15-30 per $100) must report payroll separately by class. Misclassification triggers audit adjustments that can result in surprise premium bills of tens of thousands of dollars. Agents should walk contractors through their payroll breakdown before submission, not after the audit.

Builders risk — Covers the structure under construction against damage from fire, wind, theft, vandalism, and other perils during the build. Builders risk is project-specific — a new policy is issued for each project based on the completed value of the structure. A contractor building a $2 million custom home would carry a builders risk policy with a $2 million limit for the duration of construction.

Commercial auto — Contractors operate fleets of trucks, vans, and heavy equipment. Commercial auto covers liability and physical damage for these vehicles. Construction fleets often include specialized vehicles (dump trucks, boom trucks, concrete mixers) that require specific valuations and coverage terms.

Inland marine — Covers tools, equipment, and materials at job sites and in transit. A contractor's tools and equipment — generators, scaffolding, power tools, excavation equipment — are routinely worth $50,000-$500,000 and move between job sites regularly. Standard commercial property policies don't cover property in transit or at temporary locations, making inland marine essential for construction operations.

Umbrella / excess liability — Construction projects routinely require $2M-$10M in total liability limits. Since underlying GL policies typically max out at $1M/$2M, an umbrella policy provides the excess limits needed to meet project requirements and protect against catastrophic claims.

When submitting construction accounts, the ACORD 125 and 126 are essential, and agents should supplement with details on project types, largest project value, subcontractor management practices, safety programs, and Experience Modification Rate (EMR) for workers' comp. Carriers evaluate construction risks holistically — an EMR above 1.0 or a history of serious claims can make a contractor uninsurable in the standard market regardless of other qualifications.
