Metal Erection Insurance — FAQ

Rigger's liability (also called rigging liability or hooker's liability) covers property damage to steel, equipment, and materials while they are in your care, custody, and control during rigging and lifting operations. Standard general liability policies exclude "property in your care, custody, and control" — meaning if you drop a $150,000 steel column, your GL pays nothing for the steel itself. Rigger's liability fills this gap. It's one of the most critical coverage components for any steel erection operation.

Insurance costs for steel erection contractors are significantly higher than general construction due to elevated risk exposures. A mid-sized contractor with $5M–$20M annual revenue typically pays $150,000–$400,000 annually for a comprehensive program. This breaks down approximately to: General Liability ($40,000–$80,000), Workers' Compensation ($60,000–$180,000 depending on payroll and experience modification), Rigger's Liability ($15,000–$40,000), Equipment Coverage ($20,000–$60,000), and Umbrella ($10,000–$30,000). Safety record, project types, geographic location, and crane operation complexity all affect premiums significantly.

Common NCCI workers' compensation codes for steel erection include: 5040 (steel erection — not otherwise classified), 5057 (structural steel erection — elevated work), 5059 (crane and hoisting equipment operators), 5093 (structural steel fabrication shop), and 3724 (structural steel erection on high-rise projects in some states). Using the wrong code — particularly misclassifying ironworkers under lower-rated codes — is a serious error that can result in large audit charges. Always work with a broker who understands the specific class code requirements for your operations.

Standard GL covers third-party bodily injury and property damage caused by crane operations — but NOT damage to property in your care, custody, and control (the load), NOT the crane itself, and NOT damage to the crane from mechanical failure. For comprehensive crane incident coverage you need: GL (for third-party), Rigger's Liability (for the load), Contractor's Equipment Coverage (for the crane), and potentially a separate crane liability policy if operating large lifts or city cranes. Your GL policy's "Care, Custody, or Control" exclusion is one of the most frequently misunderstood gaps in contractor insurance.

OSHA Subpart R (29 CFR 1926.750–760) governs steel erection and requires: fall protection at 15 feet or more above a lower level, controlled decking zones, shear connectors on composite floors, multi-story column bolt-up minimums, and detailed erection sequencing plans. Compliance directly affects your insurance in two ways: carriers will assess your Subpart R program during underwriting (strong programs get better rates), and violation citations create serious exposure to willful violation penalties ($156,000+) and punitive damages in civil claims. Document your Subpart R compliance program carefully — it is part of your risk management story for underwriters.

Yes — and PEMB erection has unique insurance considerations. Manufacturers like BlueScope, Nucor, and Chief often require specific insurance minimums in their erector agreement contracts. PEMB erectors also face professional liability exposure from interpreting erection drawings and managing tolerances. Warranty claims from building envelope failures (leaks, panel damage during erection) are common. Make sure your coverage includes completed operations for building envelope defects and professional liability if you're making field decisions on the erection sequence or connection details.

Workers' compensation covers employee fall injuries, medical treatment, and lost wages. However, if the fall was caused by a third party — a defective anchor point supplied by the GC, a scaffold failure maintained by another sub — the employee may also have a third-party tort claim. Your employer's liability coverage (Part B of workers comp) protects against lawsuits alleging your negligence contributed to the fall beyond what workers comp covers. For steel erection, minimum employer's liability limits of $1,000,000 per occurrence are strongly recommended given the severity of fall claims.

Owner-Controlled Insurance Programs (OCIP) and Contractor-Controlled Insurance Programs (CCIP) are wrap-up programs where one policy covers all contractors on a project. If you enroll in a wrap-up, you typically receive a credit for the GL coverage provided, but must maintain your own workers' comp and equipment coverage. Be careful: wrap-up policies often have lower limits per contractor, sub-limit your completed operations coverage, and exclude off-site activities. Always notify your own broker before enrolling in a wrap-up so you can properly credit premium and avoid coverage gaps.

Your EMR (or mod) compares your workers' comp claims history against others in your industry. A 1.00 is average; below 1.00 saves you money; above 1.00 increases premiums. Many general contractors require subcontractors to have an EMR below 1.0 or 0.85. For steel erection, maintaining a low mod requires strong fall prevention programs, rapid return-to-work protocols, and aggressive claims management. A single serious ironworker injury can affect your mod for three years. Steel erectors with low EMRs have a significant competitive advantage on large projects that screen by safety record.

Yes. When you rent a crane, the rental company will require you to carry liability for operation of the crane and often require you to purchase or maintain physical damage coverage on the equipment itself. Your contractor's equipment policy may or may not extend to non-owned equipment — check your policy's "leased or rented equipment" provisions carefully. If it doesn't cover rented cranes, you'll need either a separate endorsement or the rental company's damage waiver (which can be expensive and have significant exclusions).

Through our online client portal, you can generate standard certificates of insurance 24/7 without waiting for your agent. For special endorsements (adding additional insureds, waiver of subrogation, primary/non-contributory wording), we typically process requests within a few hours during business hours. If a project requires non-standard endorsements or policy changes, allow 1–2 business days. Never let a certificate delay keep you off a job — our portal gives you instant standard certs so you can mobilize on schedule.
