Electrical Controls & Automation

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.

Waste Management Inc. engaged in extensive electrical installations and control system integrations at their renewable natural gas facility in San Antonio, Texas. Starting with the review and development of underground and general electrical layouts, the team installed temporary power infrastructure including transformers linked to a jobsite trailer to support ongoing work. Excavation and installation of PVC conduits facilitated power and control wiring for compressors, switchboards, VFDs, MCCs, transformers, and numerous pieces of equipment. Critical structural components were constructed, including duct banks, housekeeping pads, and cable tray supports. The installation sequence progressed with setting electrical equipment like switchgear, motor control centers, and transformers. Power, control, lighting, fire alarm, security, and communication cables were pulled and terminated, integrating complex components such as variable frequency drives and methane detectors. Challenges including restoring damaged conduits and feeders, water management during trenching excavation, and coordinating equipment sequencing were systematically addressed. Specialized conduit transitions from PVC to galvanized rigid and rigid metal conduit protected exposed stub ups and maintained code compliance. Medium and high voltage feeders rated up to 35kV were installed and tested using megger equipment to ensure system integrity. Throughout the nearly year-long schedule spanning March 2024 to February 2025, rigorous fire caulking, electrical testing, security system integration, and housekeeping maintained site safety and compliance. The result was a fully commissioned electrical infrastructure supporting the facility’s renewable gas production processes.

Owens Corning Insulation Systems, LLC performed a comprehensive electrical rebuild of their E-Boost facility in Jackson, Tennessee. The work began with an extensive review of project scope and drawings, followed by development of a detailed schedule to coordinate multi-phased installation and demolition activities. Temporary power systems and safety protocols were established to enable uninterrupted plant operations during shutdowns. Workers removed existing conduit and cable trays, installed new galvanized rigid conduit, fiberglass cable trays, and power, control, and communication wiring. Major equipment replacements included MCC units, switchgear, and transformers which were precisely set and grounded in confined spaces. Coordination with vendors such as Eaton and Spang ensured integration of control panels and switchgear wiring. Lockout/tagout procedures and safety orientations maintained compliance with site standards. Testing encompassed megger and voltage verification including use of hot suits for live-dead-live testing. Challenges such as air quality concerns during demolition, complex cable routing in constrained zones, and scheduling against material backorders were met with detailed planning and continuous coordination. The work concluded with punch list completion, commissioning, as-built documentation, and site demobilization, culminating in an upgraded electrical infrastructure supporting Owens Corning's manufacturing operations.
