Workers’ Comp for California Fiber Optic, Directional Boring & Underground Telecom Contractors
Directional boring, trenching and conduit for fiber networks, pulling and splicing cable, aerial telecom strand — broadband construction is growing fast, and many standard carriers still won’t write it. If your company has 20 to 500 employees and spends $50,000 or more a year on workers’ comp, we work with markets that understand fiber crews.
Who We Place
- Fiber optic installation contractors building broadband, middle-mile and FTTH networks
- Directional boring (HDD) contractors placing conduit for fiber and telecom
- Underground utility contractors — trenching, micro-trenching, duct bank and handholes
- Fiber splicing and testing crews working in vaults, pedestals and buildings
- Aerial fiber crews — strand, lashing and overbuild on existing poles
- Subcontractors to telecom primes, cable TV and internet providers on BEAD-funded builds
California Workers’ Comp Class Codes We Place
| WCIRB Code | Classification |
|---|---|
| 6325 | Conduit Construction or Underground Wiring — conduit for fiber optic and low-voltage networks, underground cabling and underground splicing, including support excavation and tunneling at street crossings |
| 7601 | Aerial Line Construction — not power lines — aerial fiber and telecom lines, including overhead splicing |
| 5195 | Communications Cabling — fiber splicing at ground level, in utility vaults or boxes, and within buildings |
Fiber contractors often do all three kinds of work. WCIRB assigns payroll by the work each employee actually performs, so time records that separate underground, aerial and splicing hours keep payroll in the right class at audit. Coming from another state where crews were rated under NCCI 7611 or 7612? Those codes don’t exist in California; see the NCCI to California code comparison.
Why This Work Is Hard to Place
Underground fiber work isn’t the highest-rated class in construction, but it combines exposures underwriters watch closely: crews in live streets and rights-of-way beside traffic, strikes on gas, power and water lines while boring, work in vaults and handholes, and long stretches away from home on multi-county builds. Broadband money — federal BEAD funding and California’s state middle-mile network — has crews growing fast, often with new hires and layers of subcontracted crews. That growth profile is what pushes many standard carriers to decline or price the class out.
What Underwriters Want to See
- Dig Alert (811) tickets, positive locates and potholing before every bore
- Bore-path planning and a written utility-strike response procedure
- Traffic control plans and trained flaggers for street and right-of-way work
- Confined-space procedures for vaults and manholes
- Current workers’ comp certificates on file for every subcontracted crew
How Specialty Markets Look at Your Account
Standard carriers often decide on class code alone. The specialty markets we work with for high-hazard classes underwrite the company in front of them: your safety program, training and certifications, loss frequency versus severity, how your experience mod is trending, and how claims are managed when they happen. A contractor that has invested in safety can be priced on that record instead of the worst operators in its class.
That doesn’t mean every account saves money — and if your current program is the right fit, we’ll tell you. But if your premium hasn’t moved after years of clean operations, it’s worth a second look.
Situations We Help With
Broadband buildout growth
BEAD or middle-mile contracts doubled your crews in a year and your program didn’t keep up.
Subcontractor audit charges
Your audit added payroll for subcontracted crews that couldn’t show their own workers’ comp.
Payroll in the wrong class
Boring, aerial and splicing payroll isn’t split to match the WCIRB rules for your work.
Prime contractor requirements
A telecom prime or utility requires a lower mod or specific limits to stay on its vendor list.

Common Questions
Which code applies to underground fiber construction in California?
WCIRB 6325, Conduit Construction or Underground Wiring, covers building conduit for fiber and low-voltage networks, pulling cable through it, underground cabling without conduit and splicing underground cable. It also includes the excavation you do in support of that work and tunneling at street crossings.
Is fiber splicing a separate class?
It can be. Splicing fiber at ground level for others, or in utility vaults, boxes or buildings, falls under 5195 Communications Cabling, while overhead splicing falls under 7601. If your crews do all three, payroll records by class matter.
Do you place directional boring contractors?
Yes. WCIRB separately classifies tunneling other than at street crossings, so how your boring work is described on the application matters. We review it with you before your account goes to market.
We use subcontracted crews. How does that affect our workers’ comp?
At audit, payroll for subcontractors who can’t show their own workers’ comp coverage is usually added to your policy. Collecting current certificates from every crew before it starts is one of the simplest ways to avoid a large audit bill.
What size companies do you work with?
Typically 20 to 500 employees with $50,000 or more in annual workers’ comp premium.
