Multi-Site Project Expertise

Cummings Electrical played a key role in the construction of a 920,000-square-foot Walmart distribution center, partnering with Dematic—a global leader in supply chain automation—to deliver a fully integrated electrical and controls solution for one of the most advanced logistics facilities in the country. Our scope included the installation of extensive conduit and wiring systems, thousands of LED light fixtures, and the complete power distribution infrastructure supporting the facility’s high-speed conveyor systems, automated storage and retrieval systems (AS/RS), and advanced sorting technologies. We provided dedicated electrical feeds and low-voltage raceways for each major automation component, ensuring system resilience and real-time operational control.

In addition to power, our team installed the complete data infrastructure necessary to support the facility’s AI-driven robotics and smart automation platforms. This included controls wiring, PLC connections, network backbone cabling, and precise coordination of power and signal routing to minimize interference and ensure system reliability. Our collaboration with Dematic included in-depth coordination on system sequencing, equipment startup, and functional testing—ensuring all automated equipment came online smoothly and met the performance standards required for a high-volume, 24/7 distribution environment. This project not only demonstrates Cummings Electricals’ capacity to execute large-scale industrial installations but also reinforces our leadership in delivering high-performance electrical and automation solutions for the modern supply chain.

Tasked with integrating extensive EV charging infrastructure into an active manufacturing facility, the project required meticulous site preparation, precise coordination, and technical expertise. Initial site conditions included existing underground utilities, concrete-encased conduits, and landscaping barriers, necessitating careful excavation, rerouting, and concrete work. The solution involved detailed planning, utility coordination with CPS and SAWS, and precise execution of conduit installations, transformer pads, and charger stands. Technicians installed multiple 480V and 208V chargers, switchgear, transformers, and associated electrical panels, ensuring compliance with city and CPS inspections. Despite weather delays, material sourcing issues, and complex coordination with external contractors, the project successfully delivered a fully operational EV charging system. The resulting infrastructure significantly enhances fleet electrification capabilities, aligning with sustainability initiatives and operational efficiency goals.

The outdated 8MW 480V central utility plant at Medical City Dallas was replaced with a new 24MW 13.2kV automated system—executed without disrupting hospital operations. The project involved reconstructing the existing CUP and electrical distribution room, along with building a new utility yard supplying dual 12MW utility feeds to a steel structure housing permanent 1200A MTM metalclad switchgear, 1200A paralleling gear, a 3.75MW generator, and a Digital Master Controller (DMC). Phased load transfers—from existing to temporary systems, and finally to permanent gear—allowed critical systems to remain operational. The new distribution setup includes six 15kV pad-mounted substations, each serving a 480V switchboard. Automation, sequencing, and protection were managed through HMI touchscreens and protective relays, ensuring high reliability and long-term scalability.

Our team delivered full electrical scope for the interior renovation of a 120,994 SF healthcare facility. The project included major renovations (20,775 SF), minor renovations (1,829 SF), cosmetic updates (22,817 SF), and refresh renovations (73,300 SF). Scope highlights included the replacement of isolated power panels, the addition of operational procedure rooms, relocation of the lab and pharmacy, and infrastructure support for updated clinical and support spaces.

The HCA MOB and Garage consisted of construction for approximately 410,762 SF of new construction, including a 4-story, 95,307 SF Medical Office Building and a 7-story, 315,455 SF cast-in-place parking garage. The garage includes 892 spaces and is structurally designed to accommodate two future floors, adding up to 265 additional spaces. Located on the northwest quadrant of the campus, the garage features a mix of architectural finishes including precast concrete panels, metal mesh, curtain wall, and steel cable elements—supporting both functionality and campus aesthetics.

Future Energy Group LLC installed new electrical infrastructure to support dual-port Level 3 and Level 2 electric vehicle chargers at their Devine, TX site. The scope included furnishing and installing an 800A 480V NEMA 3R distribution panel, associated circuit breakers, and a 30KVA NEMA 3R transformer, along with conduit runs from utility pole to the new panels. The team coordinated utility locates and worked closely with AEP Texas for service termination and activation, ensuring compliance with all permitting requirements. During the project timeline spanning from June 2024 through February 2025, the crew addressed a schematic error involving swapped high voltage and low voltage panel setups by rerouting conduits after consultation and parts procurement, overcoming this without schedule impact. They also installed concrete pads, performed firestopping, and completed site signage installation per company environmental standards. The final phase included commissioning support, completing wiring terminations for the chargers, and field verification of equipment functionality to ready the EV charging station for operation.

Southwest Airlines undertook extensive electrical and telecom conduit and wiring installations at their Houston airport facility, including concourses, gates, international wing, tunnels, and electrical rooms. The work began with site walks, blueprint markups, and detailed material planning. This groundwork was followed by receiving and organizing deliveries, then progressing to installing rigid metal conduit and electrical metallic tubing for power and telecom backbones. Supporting hardware such as strut, allthread rods, anchors, and hangers were installed alongside pull boxes and junction boxes. MPZ panels and NIE cabinets were fabricated and mounted with precise strut frameworks. Wiring pulls and terminations for power and data were executed within these panels, while grounding rods and hubs were installed requiring specialized drilling with multiple bit extensions to navigate structural obstacles. Coordination with airport operations necessitated precise scheduling for equipment shutdowns, including breaker installations and safety lockouts. Challenges like conduit clearance adaptations, equipment breakdowns, and weather delays were addressed through careful planning and resource management. Throughout the project, continuous inspections and communications with airport and telecom inspectors ensured compliance with requirements. The project culminated with labeling, cleanup, and energizing of installed systems. This schedule, spanning from August 2024 to February 2025 and totaling over 10,600 labor hours, demonstrates a methodical approach to intricate electrical and communications infrastructure upgrades within a live aviation environment.
