Specialty Insurance for Tower & Telecom Contractors

Most turf vendor and tower owner MSAs require commercial general liability ($1M/$2M) without height exclusions, workers compensation at statutory limits, commercial auto ($1M CSL), umbrella/excess liability ($5M-$10M), and inland marine for tools and rigging gear. You also need additional insured endorsements with primary and noncontributory wording, plus waiver of subrogation on GL and WC policies.

Standard commercial general liability policies contain height exclusions (typically above 15-30 feet) or total work-at-height exclusions that void coverage for tower erection and maintenance. Specialty carriers that understand telecom risk remove these exclusions and write GL specifically for NCCI class codes 7855 (tower erection) and 7601 (telecom installation), which most standard carriers decline entirely.

Tower erection crews are typically classified under NCCI code 7855 (Iron or Steel Erection - towers) and telecom installation under 7601 (Telephone/Cable TV Installation). These are among the highest-rated WC class codes due to fall risk, with experience modification heavily impacting premiums. Some states use state-specific bureau codes rather than NCCI.

Annual premiums vary widely by crew size, revenue, work type, and claims history. A full program spans GL, WC, auto, umbrella, and inland marine, and workers comp for tower erection class codes is usually the largest single line, driven by payroll, the state rate for the class code, and your experience mod. Getting competitive quotes requires specialty brokers who access surplus lines carriers.

A certificate holder simply receives a copy of your insurance certificate - it grants no coverage rights. An additional insured is actually added to your policy and receives coverage for claims arising from your work. MSAs require additional insured status with specific wording: primary and noncontributory, meaning your policy pays first and doesn't seek contribution from the tower owner's insurance. This is a critical distinction that causes more MSA compliance failures than any other requirement.
