Telecommunications Contractor Insurance

Grandbay Financial Services places telecommunications contractor insurance from its New York and Atlanta offices for contractors across 16 states. This page covers who this program is for, why telecom contractors are underwritten differently from general construction, what Crown Castle and Verizon require of their contractors, the coverage lines a telecom program needs, and what underwriters ask when evaluating a submission.

Who this page is for

Telecommunications contractor insurance covers four distinct types of contractor, each with a different risk profile and underwriting profile.

• Tower and rooftop wireless crews. These contractors do new site builds, antenna and line upgrades, small cell and 5G installations, distributed antenna system (DAS) work, and decommissioning for the carriers. They work at height on communication towers and rooftops, and their operations are governed by OSHA fall protection standards under 29 CFR 1926.105 and 1926.104 and by 29 CFR 1910.268 for maintenance and service work. OSHA and the FCC Communication Tower Best Practices (OSHA 3877, June 2017) describe the industry as one where responsibility for safety "is fractured into many layers" because carriers contract turfing vendors who subcontract further.
• Outside-plant fiber crews. These contractors do aerial and underground construction, directional boring, and splicing for fiber networks. Underground work requires calling 811 under the PIPES Act of 2006 before digging. According to the Common Ground Alliance's 2024 DIRT report, telecommunications and water/sewer work dominated nine of the top ten root causes of the 196,977 damage reports counted in 2024.
• Inside-plant structured cabling and data center crews. These contractors install structured cabling, low-voltage systems, and data center infrastructure. Their workers compensation classification is different from tower climbers: NCCI code 7600 is for employees of telecommunications companies and is not applicable to contractors performing similar operations; contractors erecting poles, stringing overhead lines, and laying underground cable are code 7601; conduit construction is code 6325.
• Electrical contractors doing telecom power and equipment work. These contractors install power systems, backup power, and electrical infrastructure for telecommunications equipment rooms and cell sites. Their scope may overlap with both inside-plant and outside-plant work, and their workers compensation and general liability classifications depend on the specific operations performed.

Why telecom contractors are underwritten differently

Telecommunications tower work has a documented fatality record that sets it apart from general construction. OSHA's 2015 request for information found that 107 incidents from 2003 through 2013 resulted in 91 fatalities and 17 injuries, with 79 of the fatalities due to falls. OSHA counted 13 communication tower fatalities in 2013, 12 in 2014, 3 in 2015, and 6 in 2016. The Bureau of Labor Statistics counted 70 fatal injuries among telecommunications line installers and repairers from 2011 to 2015.

The layered subcontracting structure compounds the underwriting challenge. OSHA's 2015 request for information noted that "it is not uncommon to have as many as six or seven layers of subcontractors between the carrier and the company that employs the workers." This structure creates complex additional insured chains, makes certificate compliance difficult to manage, and means that the company with the most direct control over safety is often the smallest and least capitalized entity in the chain.

OSHA's communication tower safety rule remains a long-term action item with no proposed rule published as of the fall 2025 regulatory agenda. In the absence of a specific tower safety standard, OSHA applies 29 CFR 1926.500(a)(3)(iv), which excludes tower erection from the general construction fall protection criteria in 1926.502 and instead applies 1926.105 (safety nets above 25 feet where other means are impractical) and 1926.104 (belts, lanyards, and lifelines). Hoisting personnel by crane or derrick is prohibited except where the employer shows conventional means would be more hazardous or are not possible under 29 CFR 1926.1431, and OSHA directive CPL 02-01-056 (July 2014) governs inspections of tower work involving hoisting personnel.

ANSI/ASSP A10.48-2023 covers safety practices for the construction, demolition, modification, and maintenance of communication structures. ANSI/TIA-222-H (2017) is the structural standard for antenna supporting structures. FCC occupational RF exposure limits under 47 CFR 1.1310 apply where workers are fully aware of the potential for exposure and can exercise control over their exposure. Antenna structures needing FAA notice must be registered before construction with the registration number displayed at the base under 47 CFR 17.4 and painted and lighted under 47 CFR 17.21.

What carriers and tower owners require of their contractors

Crown Castle publishes a public contractor insurance requirement summary. It requires general liability of $1,000,000 per occurrence, $2,000,000 aggregate per project, and $2,000,000 products and completed operations; auto of $1,000,000 combined single limit; workers compensation at statutory limits with employers liability of $100,000 each accident, $100,000 disease each person, and $500,000 disease policy limit; and excess of $5,000,000 per occurrence and aggregate. General liability and excess must be primary and non-contributory. Additional insured status for ongoing and completed operations must be on endorsements equivalent to ISO CG 20 26 04 13 and CG 20 37 04 13; Crown Castle states that "CG 20 10 04 13 is not acceptable for ongoing operations." Waiver of subrogation is required on all policies, and 30 days' notice of cancellation is required. Turnkey contractors must add professional liability of $2,000,000 per occurrence and aggregate, maintained for three years. Crown Castle states: "You cannot qualify as a Crown Castle vendor/contractor if your policies do not comply with our requirements."

Verizon's public purchase order terms require statutory workers compensation with employers liability of not less than $1,000,000, commercial general liability of not less than $2,000,000 per occurrence, auto liability of $1,000,000, and professional liability of not less than $2,000,000, with Verizon as additional insured and the supplier's policy primary. T-Mobile requires a certificate of insurance meeting its contractual minimums before work starts but does not publish the amounts. American Tower, SBA Communications, AT&T, Ericsson, and Nokia set their requirements in each master services agreement and do not publish the amounts.

Coverage a telecom contractor program needs

A complete telecommunications contractor insurance program typically includes the following lines. Coverage depends on the policy wording and endorsements, and the specific limits required by each carrier, tower owner, or contract must be confirmed separately.

• General liability. Tower and rooftop crews require a policy that does not exclude height work, action over claims, or completed operations. Crown Castle requires additional insured endorsements equivalent to ISO CG 20 26 04 13 for ongoing operations and CG 20 37 04 13 for completed operations. Per-project aggregates are typically required by tower owners. Coverage depends on the policy wording and endorsements.
• Umbrella or excess liability. Crown Castle requires excess of $5,000,000 per occurrence and aggregate, primary and non-contributory. Other tower owners and carriers set their own limits in each master services agreement. Coverage depends on the policy wording and endorsements.
• Commercial auto. Crown Castle requires $1,000,000 combined single limit. Verizon requires $1,000,000. Fleet coverage for service vehicles, bucket trucks, and directional boring equipment is typically included. Coverage depends on the policy wording and endorsements.
• Workers compensation and employers liability. Crown Castle requires statutory workers compensation with employers liability of $100,000 each accident, $100,000 disease each person, and $500,000 disease policy limit. Verizon requires employers liability of not less than $1,000,000. The correct NCCI classification code matters: code 7601 for pole erection and line work, code 6325 for conduit construction, and code 7600 for telecommunications company employees (not applicable to contractors). Coverage depends on the policy wording and endorsements.
• Professional liability. Crown Castle requires turnkey contractors to carry $2,000,000 per occurrence and aggregate, maintained for three years. Verizon requires not less than $2,000,000. General liability policies typically exclude professional services. Coverage depends on the policy wording and endorsements.
• Inland marine for tools, test equipment, and installation floaters. Specialized telecommunications test equipment, fiber cable, and installation materials are high-value items subject to theft and damage on job sites and in transit. An installation floater covers materials during installation before acceptance by the owner. Coverage depends on the policy wording and endorsements.
• Riggers liability. Where crews lift antennas and equipment by crane or derrick, riggers liability covers damage to property being lifted. Hoisting personnel is prohibited except where conventional means would be more hazardous or are not possible under 29 CFR 1926.1431. Coverage depends on the policy wording and endorsements.
• Contractors pollution liability. Outside-plant crews that bore or trench near existing utilities have pollution exposure from soil disturbance and utility strikes. General liability policies typically exclude pollution. Coverage depends on the policy wording and endorsements.

What underwriters ask

• NWSA certification and NATE training records. NWSA (National Wireless Safety Alliance) is a nonprofit certification body founded in 2015 whose certifications (Telecommunications Tower Technician 1 and 2, Antenna and Line, Advanced Rigging Concepts, and Foreman) are accredited by ANSI to ISO 17024 for a five-year period. NATE's Climber/Rescuer Training Standard (revised January 2022) is a training standard published by a membership association, not a certification. Underwriters and customers look for both. Carriers and tower owners do not contractually require NWSA or NATE by name in their published requirements, but the credentials are the industry standard for demonstrating a trained workforce.
• ANSI/ASSP A10.48 safety programs. ANSI/ASSP A10.48-2023 covers safety practices for the construction, demolition, modification, and maintenance of communication structures. Underwriters ask whether the contractor has a written safety program that addresses the A10.48 standard, including rescue plans and RF awareness training.
• RF awareness and rescue plans. FCC occupational RF exposure limits under 47 CFR 1.1310 apply where workers are fully aware of the potential for exposure and can exercise control over their exposure. Underwriters ask whether crews have RF awareness training and whether rescue plans are in place for each site before work begins.
• Subcontractor controls. OSHA and the FCC Communication Tower Best Practices (OSHA 3877) identify the layered subcontracting structure as a primary safety challenge. Underwriters ask how the contractor vets and monitors subcontractors, whether subcontractors are required to carry matching insurance, and whether certificates are collected before work begins.
• 811 call-before-you-dig practices. For outside-plant crews, underwriters ask whether the contractor has a written 811 compliance procedure and whether locate requests are documented for every excavation. The Common Ground Alliance's 2024 DIRT report identified telecommunications work as a leading source of underground damage reports.
• Workers compensation class codes. Underwriters verify that the workers compensation policy includes the correct NCCI codes for each type of work: 7601 for pole erection and line work, 6325 for conduit construction, and the appropriate inside-plant codes for structured cabling crews. Misclassification is a common audit issue for telecom contractors with mixed operations.
