Wolf Line Construction is an outside plant (OSP) utility contractor for hyperscale data center projects, working as a subcontractor to the general contractors that build them. We self-perform site utilities, medium-voltage underground distribution and ductbank, high-voltage transmission feeds (OPGW and ADSS), and the OSP / dark fiber backbone to the carrier Meet-Me Room (MMR). Everything outside the building, up to the wall.

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 underground, 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; Optical Ground Wire (OPGW) and All-Dielectric Self-Supporting (ADSS) cable for the high-voltage transmission feeds; and the ADSS, outside plant (OSP), and dark-fiber backbone connecting every carrier Meet-Me Room (MMR) to the outside world. 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.

Outside Plant, Not Inside Plant

Wolf Line is an outside plant contractor. Our scope covers everything outside the building envelope (site utilities, underground power distribution, transmission feeds, and the fiber backbone) and terminates at the carrier Meet-Me Room. We do not perform inside plant electrical or white-space fit-out. That means we complement the inside-plant electrical contractor on your team rather than competing for their scope, 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: GC-licensed across multiple states, bondable to $50M, 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 and licensed in South Carolina, Virginia, and North Carolina, with crews working across the Southeast's data center growth corridor. Our teams and 100-vehicle fleet mobilize for utility and data center projects nationwide.
