Welcome to Global Diversified Voltage
Your Trusted Medium Voltage Partner
From commercial and industrial to government, military, and residential — here's a sample of our recent work.
QTS Data Center-Phoenix
HELIX ELECTRIC
QTS Phoenix Data Center 3 is a large-scale hyperscale campus in Glendale, Arizona, planned across approximately 375 acres with 16 data center buildings totaling roughly 3 million square feet and designed for more than 750 MW of critical power capacity. Developed in multiple phases and supported by a planned 29-acre adjacent substation, the campus is designed to accommodate rapid, large-scale deployments in one of the fastest-growing data center markets in the country. GDV’s scope included medium voltage construction supporting the backbone of the campus power infrastructure, where reliability, coordination, and execution are essential to delivering power to a mission-critical environment. At this scale, medium voltage work is what enables resilient distribution, future expansion, and the continuous uptime modern data center operations demand.
Electric Bus Infrastructure
LONG BEACH TRANSIT
Long Beach Transit's Electric Bus Infrastructure project supported the agency's ongoing transition toward a zero-emission fleet, delivering the charging infrastructure needed to power a growing roster of battery-electric buses serving Long Beach and the surrounding communities. As one of the earliest transit agencies in the region to adopt battery-electric technology, Long Beach Transit has continued to expand its charging depot capacity to keep pace with fleet growth and ridership demand. GDV's scope included electrical infrastructure supporting the depot's charging systems, work that is essential to reliable, overnight fleet charging and daily service readiness. Keeping buses charged and ready to serve the public every day required precise coordination with transit operations, disciplined scheduling, and a systems-focused approach throughout construction.
Heat Treat Install
RELATIVITY SPACE
Relativity Space is an aerospace manufacturer based in Long Beach, California, known for pioneering the large-scale 3D printing of rocket structures and engines as part of its mission to build the next generation of reusable launch vehicles. This project supported the installation of a heat treatment furnace system used in the company's advanced manufacturing process, including the exhaust infrastructure required to safely and efficiently vent the system within an active production facility. GDV's scope included the electrical installation supporting the heat treat furnace system, work performed within a fast-paced, high-precision manufacturing environment where equipment uptime is critical to production schedules. Supporting a critical piece of equipment within a cutting-edge aerospace facility demanded precision, careful coordination with manufacturing operations, and a disciplined approach throughout.
Sea-based X-band Radar (SBX-1)
TDX GLOBAL
The Sea-Based X-Band Radar (SBX-1) is a unique floating radar platform designed to operate in challenging offshore environments, including high winds and rough seas. Deployed in 2006, the system has supported operations across the Pacific, including Hawaii and Alaska. The structure includes multiple communication radomes along with a large central dome housing a significant radar array, making it one of the more distinctive maritime platforms in operation. Our work supported critical infrastructure associated with this specialized facility, where reliability and consistent performance are essential. Due to the platform’s offshore conditions and technical complexity, all work required careful coordination, adherence to strict standards, and a strong focus on safety and quality. Execution demanded precision, adaptability, and a disciplined approach to ensure dependable performance in this uniquely demanding operating environment.

Superchargers
TESLA
This project involved the construction of 11 Tesla Supercharger stations, delivering the site and utility infrastructure needed to support high-demand EV charging in a fast-growing transportation segment. Developed to provide reliable, accessible charging capacity for Tesla drivers, the project required coordinated civil and utility work to prepare the site for long-term use and daily public operation. GDV’s scope included asphalt paving, striping, concrete, signage, and utility infrastructure, with each element playing a critical role in making the site functional, durable, and ready for service. Successful execution here came down to clean coordination between sitework and infrastructure, delivering an installation built for safe traffic flow, clear user access, and dependable utility service from day one.
2,000 KVA Transformer for CMF
LA METRO
For LA Metro's Central Maintenance Facility (CMF) — a critical hub for LA County's rail and bus operations — GDV delivered and installed a 2,000 kVA transformer and a 600A fusible disconnect switch, reinforcing the facility's power capacity. CMF depends on reliable electrical infrastructure to keep its maintenance operations running without interruption, so GDV executed the procurement and installation in close coordination with facility staff to minimize disruption to ongoing work. Precise installation and safety-first execution leave CMF equipped to support continuous, reliable maintenance of LA Metro's fleet.
Panel Upgrade Phase 2 & 3
CAL STATE LA
The CSULA Panel Upgrade Phase 2 and Phase 3 project involved the continued modernization of electrical distribution infrastructure across Cal State LA's approximately 175-acre campus in Los Angeles, building on earlier upgrade work to improve capacity, safety, and long-term reliability. Delivered in two sequential phases on an active university campus supporting students, faculty, staff, and daily operations, the work required careful planning, phased sequencing, and disciplined execution to minimize disruption to ongoing academic activities. GDV's scope included the removal and replacement of aging electrical distribution panels and associated components across multiple campus buildings, supporting improved power quality and system reliability within the campus distribution network. Precision, safety, and close coordination were essential to completing the panel upgrades cleanly and reliably in an environment where continuous campus operations had to be maintained.
Media Arts Building
BIOLA UNIVERSITY
Biola University’s Snyder School of Cinema & Media Arts building in La Mirada, California is an approximately 45,000-square-foot, three-story studio facility designed to support the full workflow of film, television, digital media, and game design education. The project includes a 3,000-square-foot soundstage, a 285-seat theater, editing suites, classrooms, computer labs, and specialized production spaces that position the facility among the most advanced media training environments in the region. GDV performed the medium voltage scope supporting the building’s core electrical infrastructure, where reliable power distribution is essential to serving high-performance studio, theater, and post-production environments. On a facility built to prepare the next generation of media professionals, the medium voltage system plays a critical role in delivering the capacity, stability, and long-term reliability required across the campus expansion.
Midfield Satellite Concourse
LOS ANGELES INT'L AIRPORT
The Los Angeles International Airport (LAX) Midfield Satellite Concourse is a facility designed to expand passenger capacity and enhance airport operations at one of the busiest travel hubs in the world. The concourse accommodates 22 wide-body swing gates serving both domestic and international flights and includes approximately 750,000 square feet of passenger and operational space, 50,000 square feet of passenger tunnel access, 80,000 square feet of utility tunnels, and a ramp-level bus station for terminal connectivity. As one of the largest and most complex airport infrastructure projects in the United States, it plays a critical role in supporting LAX's position as a major global gateway to the Pacific. Our work supported essential electrical infrastructure within this high-demand aviation environment, where system reliability and operational continuity are critical to passenger movement and airport functionality.
