Metal Erection Insurance Coverages | Steel Erection Contractor Policies

Six Coverages Every Metal Erection Contractor Must Have

Steel erection is one of the most hazardous construction trades. Your insurance program must match those risks — generic contractor policies leave fatal coverage gaps.

🛡️

General Liability Insurance

The foundation of your program. Covers third-party bodily injury, property damage, and completed operations for all metal erection and steel construction activities.

Third-party bodily injury on job sites
Property damage from crane and rigging operations
Falling object liability (the #1 steel erection risk)
Products and completed operations coverage
Collapse coverage for demolition/dismantling
Additional insured endorsements for GCs and owners

Typical limits: $2M/$4M per occurrence/aggregate (many projects require $5M+)

🏗️

Rigger's Liability / Crane Liability

Critical coverage for steel erectors. Standard GL policies exclude property damage to property in your care, custody, or control — exactly what happens when you're rigging someone else's steel.

Property in your care, custody, and control
Dropped loads and rigging failures
Crane swing damage to adjacent structures
Steel members damaged during placement
Craned equipment and prefabricated sections
Wrecker and salvage costs after crane incidents

Limits: Match the value of steel you're handling at peak projects

👷

Workers' Compensation

Iron workers and steel erectors face some of the highest injury rates in construction. Your workers comp program must reflect the actual risk — and use the correct NCCI classification codes.

Fall injuries from elevated steel work
Crush injuries from steel placement errors
Welding flash and burn injuries
Arc flash and electrical exposure
Occupational hearing loss from heavy equipment
OSHA 1926 Subpart R compliance documentation

Key codes: NCCI 5040 (steel erection), 5057 (ironworkers), 5059 (crane ops)

🔧

Contractor's Equipment Coverage

Mobile cranes, boom trucks, forklifts, welding equipment, and rigging gear represent enormous capital. Equipment coverage protects these assets on and off the job site.

Mobile cranes (all-terrain, crawler, rough terrain)
Boom trucks and carry decks
Welding machines and cutting equipment
Rigging hardware: hooks, shackles, slings, spreader bars
Theft from secured job sites
Equipment in transit between project locations

Coverage basis: Replacement cost; blanket or scheduled per unit

📋

Professional Liability (E&O)

If your company provides structural engineering oversight, connection design, or erection sequencing recommendations, you need professional liability — even if you're primarily a field crew.

Erection sequence and shoring plan errors
Connection design review liability
Pre-engineered building assembly specification errors
Load path analysis and bearing support advice
Submittal review and approval liability
As-built discrepancy claims

Typical limits: $1M–$2M per claim; claims-made basis

☂️

Commercial Umbrella / Excess Liability

A single catastrophic steel erection collapse or crane fatality can generate claims in the tens of millions. Umbrella coverage is essential protection for any active steel crew.

Excess over GL, auto, and employer's liability
Crane catastrophe protection
Multi-fatality incident coverage
Major project GC and owner contract requirements
Defense costs beyond primary policy limits
Follow-form coverage over underlying policies

Typical limits: $5M–$25M; $10M+ common for major projects

Coverage	Small (<$2M revenue)	Mid-Size ($2M–$10M)	Large ($10M+)
General Liability	$2M/$4M	$2M/$4M	$2M/$4M + excess
Rigger's Liability	$1M	$2M–$5M	$5M+
Workers' Comp	Statutory	Statutory + EL $1M	Statutory + EL $2M+
Equipment (blanket)	$500K	$1M–$3M	$3M+ / scheduled
Professional Liability	$500K	$1M	$2M–$5M
Umbrella	$5M	$10M	$15M–$25M

The Rigger's Liability Gap Most Contractors Miss

Standard CGL policies include a "care, custody, and control" exclusion. This means if steel in your rigging is damaged during placement — a load hits a beam, a crane tips, a sling fails — your GL policy pays nothing for the steel itself.

Scenario:

A steel erection crew drops a $180,000 pre-fabricated column section due to a rigging hardware failure. The GL policy excludes "property in your care, custody, and control." Without rigger's liability, the contractor pays out of pocket.

Solution:

Rigger's liability coverage specifically closes this gap, covering property damage to steel, equipment, and materials while in your rigging or handling operations.
