Electrical Construction & Commissioning

Sitewide electricians installing medium-voltage cable in an open trench on site

Intro

Licensed electrical construction and commissioning, from cable installation through to energization.

Sitewide delivers electrical construction, pre-commissioning and commissioning directly to owners, EPCs and general contractors. Our licensed crews cover cable and associated equipment, raceways, medium-voltage terminations and splices, classified-area installations, testing, completions and final turnover. For data center work that includes dedicated low-voltage depth alongside MV capability.

Scope

Service Scope

Completions management with ITR/FTR tracking and documentation
Vendor-assisted commissioning
Project management, oversight and supervision
Turnkey commissioning services

Low-voltage capability for data centers

Data centers place outsized demand on LV scope. Sitewide supports installation, termination, testing and deficiency tracking all the way to energization.

LV raceway systems below 1kV: conduit, cable tray, wireway and underground ductbank
Cable pulling for LV power, control, instrumentation and communications
Termination: prep, stripping, lugs, connectors, glands, heat-shrink and cold-shrink
Grounding and bonding verification for raceways, equipment, shields and conductors
Continuity, insulation-resistance, phase-rotation and point-to-point testing
Documentation and deficiency tracking through final inspection, turnover and energization

Why it matters

Hyperscale campuses compress years of electrical scope into months. Our crews mobilize fast, transition directly from concluding megaprojects to new sites, and work to a right-first-time standard that protects commissioning milestones. Backed by a pool of 800+ electricians and trusted field supervision, we scale to match your schedule, not the other way around.
