Wolf Line Construction is an outside plant (OSP) and site utilities subcontractor for hyperscale data center projects. We self-perform the power and fiber infrastructure that carries a campus from the grid to the data hall: site utilities, medium-voltage underground distribution and ductbank, the medium-voltage distribution and service-entrance work inside the building, cable tray and pathways, high-voltage transmission feeds (OPGW and ADSS), and the OSP and dark fiber backbone with terminations at the carrier Meet-Me Room (MMR). Our scope stops at the critical-power and white-space fit-out.

Utility-Grade Discipline, Data Center Speed
Data center schedules don't have slack, and GCs need subs who treat speed-to-market and 100% uptime as baseline. Wolf Line built that discipline over decades of transmission, distribution, and fiber optic work for the nation's utilities, and we apply it to the site utilities, medium-voltage distribution, and fiber infrastructure every campus depends on.
What Wolf Line Self-Performs
Our self-perform scope covers the critical-path utility work on a hyperscale campus: the wet and dry utilities feeding the site; medium-voltage ductbank and underground distribution from the substation tie-in to the building pads; the medium-voltage distribution and service-entrance work inside the building, with cable tray and pathways; Optical Ground Wire (OPGW) and All-Dielectric Self-Supporting (ADSS) cable for the high-voltage transmission feeds; and the OSP and dark-fiber backbone connecting every carrier MMR to the outside world, with terminations. Wolf Line handles installation, testing, and long-term maintenance under one contract, giving GC preconstruction teams a single point of accountability and keeping commissioning on schedule.
Where Our Scope Starts and Stops
Wolf Line carries the power and fiber from the grid, through the building, to the data center's electrical line-up and the carrier Meet-Me Room. That includes the site utilities, the medium-voltage distribution underground and into the building, the transmission feeds, cable tray and pathways, and the OSP and dark fiber backbone with its terminations. Our scope stops at the critical-power and white-space fit-out: the UPS, generators, paralleling switchgear, PDUs, busway, and rack-level power inside the data hall. That means we extend your data center electrical integrator rather than competing for the white space, and a GC can draw a clean line between our work and theirs on day one.
Prequalified & Ready for Your Process
Wolf Line is built to clear the standard prequal requirements from Turner, Whiting-Turner, DPR, and similar GCs: licensed in 14 states, bondable to $50M per project and $100M aggregate, fully insured, with a documented safety program, a three-year EMR history well inside hyperscaler thresholds, and audited financials. Our crews work to strict Methods of Procedure (MOPs) and our supervisors carry OSHA 30 certification. Badging, escorted access, force protection, and the cleanliness and cable-management protocols of mission-critical environments are already part of how our teams operate.
From Greenfield to Go-Live
Wolf Line has built our business on being the partner a GC can hand a turn-key scope to and trust that it's handled. That holds from greenfield site work and first-generation campus utilities through retrofits, fit-outs, and the ongoing fiber and distribution work that a facility needs throughout its life. Wolf Line operates as an extension of your project team, with the bench strength for multi-building campuses up to 500 acres and the discipline to keep our scope off the punch list at turnover.
Where We Work
Wolf Line is headquartered in North Charleston, South Carolina, in the middle of the Southeast's data center growth corridor, and our crews and 100-vehicle fleet mobilize nationwide. We hold contractor licenses in 14 states (Alabama, Arkansas, Arizona, Idaho, North Carolina, North Dakota, New Mexico, Ohio, Oregon, South Carolina, Tennessee, Virginia, Washington, and West Virginia). Most of our outside-plant and utility line work is performed under the National Electrical Safety Code, which most states exempt from electrical-contractor licensing, so we operate well beyond those states. Where a project's in-building scope requires a state license we don't hold, we obtain it. We go where your campus is.
Frequently Asked Questions
-
Wolf Line is an outside plant and site utilities contractor. We carry the power and fiber from the grid, into the building, to the data center's electrical line-up and the carrier Meet-Me Room (MMR), including medium-voltage distribution inside the building, cable tray and pathways, and fiber terminations. We stop at the critical-power and white-space fit-out (UPS, generators, PDUs, busway, and rack power), so we complement your inside-plant electrical contractor without scope conflict.
-
Site utilities (wet and dry), medium-voltage underground distribution and ductbank from substation tie-in to building pads, medium-voltage distribution and service-entrance work inside the building, cable tray and pathways, high-voltage transmission feeds including OPGW and ADSS installation, and the OSP and dark fiber backbone with terminations at the carrier MMR, plus testing and long-term maintenance on all of it.
-
Decades of self-performed utility construction: high-voltage transmission up to 760kV, distribution, and fiber optic builds for utilities nationwide, including federal infrastructure work for the Western Area Power Administration. The same crews, equipment, and planning discipline now serve hyperscale campus scopes.
-
Yes. Wolf Line is licensed in 14 states, bondable to $50M per project and $100M aggregate, fully insured, with a 2025 EMR of 0.76, OSHA 30-certified supervision, and a documented safety program and audited financials available on request.
-
Over 200 certified electrical professionals, all OSHA 1910.269-certified, supported by a fleet of 100 specialized vehicles and in-house engineering and project management.
-
Wolf Line holds contractor licenses in 14 states and works nationwide. Most of our outside-plant and utility line scope is performed under the National Electrical Safety Code, which most states exempt from electrical-contractor licensing, so we mobilize coast to coast without a separate state license. Where a project's in-building scope requires a state license we don't hold, we obtain it. We are headquartered in the Southeast and licensed in major data center markets including Arizona, Ohio, Virginia, and the Pacific Northwest.
