Project Overview
Toyota Material Handling expanded its Columbus, Indiana campus with the addition of Plant #5, a 285,000-square-foot manufacturing and assembly facility designed to support the company’s continued growth in North American operations.
R.E. Dimond and Associates provided comprehensive MEPT design services for this new construction, which includes 260,000 SF of production and assembly space and 24,000 SF of administrative offices.
Location: Columbus, Indiana
Size: 285,000 SF
Completion: January 2026
Market: Industrial / Manufacturing
Services: Mechanical, Electrical, Plumbing, and Telecommunications Engineering
Engineering Highlights
Large-scale rooftop air units
The plant’s mechanical systems are served by (12) direct-expansion rooftop units (DX RTUs) and (4) dedicated make-up air handling units (AHUs) to maintain optimal air quality and comfort across large-scale industrial spaces. Exhaust systems and inverters were strategically integrated to support energy efficiency and production reliability.
Storm-ready shelters
The locker rooms were designed to meet ICC 500 storm shelter requirements, ensuring occupant safety during extreme weather events. The shelter areas are storm-rated and structurally reinforced to remain self-sustaining even if the surrounding facility were to collapse – a design feature that prioritizes life safety and resilience.
Future solar conduits ready-to-go
Electrical infrastructure includes rough-in provisions for future solar conduit and disconnects, enabling seamless integration of renewable energy systems as Toyota continues to advance its sustainability goals.
Plumbing systems installed included Natural Gas and Compressed Air loop systems. Delivering these services with a consistent supply for all heating and process equipment. The office was provided with a gas fired water heater and recirculating hot water return loop. Maintaining the temperature of the system, to allow all users continuous hot water when a faucet is turned on.
Through close coordination with the design and construction teams, R.E. Dimond delivered a technically advanced, efficient, and resilient facility aligned with Toyota’s global standards for quality and sustainability.
