FAQ
Industrial & Warehouse questions, answered
Straight answers for developers, facility managers, and the operations people who have to keep the floor moving while the work happens. For the service-by-service detail, see our industrial electrician in Tucson page.
How do you size the electrical service for a spec warehouse with no tenant yet?
From the tenant profiles the building is likely to attract, not a single guess. A dry-goods logistics operator, a light manufacturer, and a cold-storage user draw very different loads; we size the service and the utility transformer for the range the shell is being marketed to, leave spare capacity in the gear, and stub conduit so a heavier tenant can upgrade without trenching the truck court again. Our in-house engineers run the load analysis behind that decision.
Can you design the lighting before the racking layout is final?
We can design it, but we would rather not hang it. A high-bay layout drawn to an open floor gets shadowed the day the racks go in. We build the fixture layout from the racking plan — aisle by aisle, at the height the operation will run — with occupancy control so empty aisles sit dark. If the racking is still moving, we rough in the circuits and hold the fixture locations until it is set. Our LED lighting retrofit page covers the same problem in an existing building.
Can you add forklift or fleet charging without a service upgrade?
Sometimes. Charging is a continuous load, so it comes down to a demand calculation against the actual service, the existing panels, and how many chargers run at once. Where the capacity is there, we add the charging circuits and the ventilation the battery area needs; where it is not, we plan the upgrade and the TEP or Trico coordination up front. For electric truck and van fleets, our commercial EV charging page covers the capacity question in depth.
How do you keep a distribution center running while you work in it?
By building the new alongside the old and cutting over in windows the operation approves. Shutdowns are scheduled in writing, taken overnight or on a weekend, and limited to one zone at a time; dock power, yard lighting, and life safety stay live through every phase. The crew that opens a shutdown closes it, and the tie-in is tested before the next shift starts.
Who handles the trenching for dock, yard, and site power?
We do, with our own equipment. Dock levelers, gate operators, yard lighting, and guard shacks all need power run underground across the truck court, and that trenching is usually the first thing an electrical contractor farms out. We self-perform trenching and underground work with an owned Cat fleet and certified operators, so the site power is one scope on one schedule.
How early should we bring TEP or Trico into an industrial project?
As early as the site plan. A large service and a new transformer carry long utility lead times, and those dates set the schedule for the whole building. We submit the application early, build the primary conduit, transformer pad, and duct banks to TEP's standards from day one, and keep the utility's dates visible in the project schedule. Our walkthrough of TEP new service requirements shows how the process runs; the same holds with Trico in rural Pima County.
