MasTec (NYSE: MTZ) is one of the largest infrastructure primes in the country — communications, power delivery, and pipeline work through a family of operating companies that includes Henkels & McCoy. Its communications segment hires fiber, wireless, and fulfillment subs at national scale, with compliance discipline to match. We build the package that clears MasTec-company review: prime-spec limits, real endorsements, entity-correct certificates.

The package MasTec-company subs are typically asked to carry — requirements vary by operating company and customer program, so always confirm your subcontract’s exhibit:
$1M per occurrence / $2M aggregate with additional insured status for the contracting entity — ongoing and completed operations — primary and non-contributory, with a waiver of subrogation. Endorsements on the policy, not description-box promises.
Statutory workers’ comp in every state your crews touch, with $1M employers liability. Compliance systems verify comp per state — multi-state crews need multi-state endorsement, not assumptions.
$1M combined single limit across owned, hired, and non-owned vehicles — with fleet and radius rated for how the routes actually run.
$2M–$5M over GL, auto, and employers liability on larger scopes and programs with higher flow-down limits. Following-form, so it inherits the endorsements underneath.
Boring, trenching, and underground scopes increasingly carry pollution requirements — drilling fluid, fuel, and disturbed soil are excluded by GL. Our CPL page covers the details.
Like the other mega-primes, MasTec operates through multiple legal entities — your work order may come from Henkels & McCoy or another operating company. Certificates must name that entity exactly, and utility-segment scopes can carry utility-grade specs on top of telecom norms.
If your route sheets or work orders trace back to MasTec, this package applies to you.
Aerial and underground construction on carrier and BEAD-funded programs run through MasTec communications companies.
Macro, small cell, and in-building scopes on wireless deployment programs.
Install and service work on ISP fulfillment contracts.
Power delivery and gas-adjacent scopes where utility insurance specs apply.
Underground scopes with XCU-clean GL and pollution liability priced up front.
MasTec programs commonly verify through contractor-management platforms — keep documents current or the POs stop.
Generic agents quote limits off a checklist. We build to the program — endorsements, entities, platforms, and the scope your crews actually run.
We keep your program matched to the strictest requirement across MasTec companies you touch — one package, every route sheet — with certificates that survive platform review.
Additional insured on GL and auto, waivers where required, primary and non-contributory backed by actual endorsements — the details compliance platforms bounce certificates over.
Renewal certs issued before expiration, because program compliance systems flag lapses automatically and stopped POs cost more than premium ever will.
Boring and trenching subs get WC class codes that match the work, XCU-clean GL, and pollution liability priced up front.
What crews ask before taking MasTec work.
The typical floor across communications programs: $1M/$2M GL with additional insured status (ongoing and completed ops), primary and non-contributory, waivers of subrogation, statutory workers comp with $1M employers liability, and $1M CSL auto. Utility-segment scopes and larger programs push umbrella requirements of $2M–$5M and add pollution liability for underground work.
Name the entity on your subcontract — often an operating company such as Henkels & McCoy rather than MasTec itself. Wrong-entity certificates are a routine onboarding stall across all the family-of-companies primes.
Commonly, yes — expect verification through contractor-management systems (ISNetworld and similar) with automated flagging of lapses and endorsement gaps. Renewal certificates need to land before expiration, not after.
With scope, payroll, and vehicle details ready: quoted and bound within a business day, entity-correct certificates same day after binding.
