Charging load is now the line item that surprises fleet and plant owners most, and it is a utility conversation before it is a construction one. A depot that plugs in forty vehicles overnight asks for a service the original building never contemplated, and an EV component plant adds test cells and formation equipment whose demand is hard to guess. We help automotive and EV owners settle the electrical number early, then build the rest of the facility around it.
Our buyers in this segment fall into four groups: component and module manufacturers, fleet operators converting to electric vehicles, dealership and service groups updating shops, and logistics firms that handle vehicles and parts. Their concerns overlap in a few places, such as the electrical service, the floor, the fire authority's view of battery areas and the schedule effect of utility make-ready work, and they differ elsewhere. A plant cares about tolerances and takt time. A fleet cares about charger uptime and snow.
We cover the building form in more detail on our automotive and EV plant page. This page is for the owner deciding where to put capital and which risks to take on first, and it describes how we approach each type of project in Colorado.
From charging pads to formation rooms
For fleets, scope begins with the yard. We grade and pave the parking and charging areas, set conduit and pull boxes in duct banks, pour charger pads and bollards, and install canopy foundations and lighting. Because chargers are added in stages, we install empty conduit and pull strings for the full build-out and leave room for transformers and switchgear. Lighting and camera poles are set in the same pass as the conduit, and our yard lighting and electrical site work package coordinates them.
For component plants, scope starts with the process: machining or stamping cells, battery pack assembly, end-of-line test, and receiving and shipping docks. Battery formation, charging and storage rooms bring special detailing for ventilation, fire separation and spill control, which the design team resolves with the fire authority. We build the rooms to that design, hold the inspections and keep the documentation the insurer will ask for. Service bays and shops for light and heavy vehicles are covered under maintenance shops and service bays.
Plants, depots, shops and parts centers
The buildings in this segment take several forms. A component plant needs a flat floor, high bays and a heavy electrical service. A fleet depot needs wide bays, trench drains, high doors for tall vehicles and a yard laid out for turning, charging and parking. A dealership service shop needs lifts, an alignment bay and a clean customer entry. A parts center needs racking and truck docks, and is closer to the buildings we describe for logistics and distribution.
Fleet facilities in particular benefit from a standard building. Public agencies, delivery firms and school transportation groups often run several depots, and a repeatable design, with the same bay width, the same electrical room and the same charger layout, cuts cost and speeds approval. Our automotive fleet facilities work is organized around that approach and is flexible enough to adapt to each parcel.
Corridors, dealerships and the history of vehicle plants
Colorado's automotive footprint is mostly service, logistics and component work, with a few notable production examples in its history. A Neoplan bus plant opened in Lamar in 1981, employed 650 people and closed in 2006. The experience of a rural plant of that size shows how heavily vehicle manufacturing depends on labor, access and a steady order book, and it is one reason owners ask for flexibility in the building. In Englewood, a Toyota dealership was among the city's top three employers in 2023, a reminder that service and retail make up a large part of the sector.
Access to the highways shapes depot and parts locations. Sheridan is served by US 85, US 285 and State Highway 88, which run through the south Denver industrial corridor. Limon is called the Hub City because Interstate 70, US 24, US 40, US 287 and Colorado Highway 71 all meet there, and it is served by the Union Pacific Railroad and the Kyle Railroad. A parts or vehicle-handling operation in Limon or a service center near Lamar can reach a wide area of the plains, which is a point we raise early in site selection.
Electrical service, snow and the fire authority
Three issues recur on these projects. The first is electrical service. The utility's available capacity, the transformer lead time and the cost of extending lines can add months, and we ask for a utility meeting before the site plan is final. The second is weather. Denver averages about 49 to 54 inches of snow per year, so depots need drainage that keeps meltwater off vehicle paths, heated or covered charging where reliability matters, and snow storage areas. The third is the fire authority's view of battery storage and charging inside a building, which varies by jurisdiction.
The state also plays a part. HB22-1362 requires a county or municipality that updates a building code on or after July 1, 2023 to adopt an energy code at least as stringent as the 2021 IECC along with the state model electric and solar ready code. We read how each building department applies those provisions to commercial buildings, since they can bear on conduit, panel capacity and roof layout. Related industrial work in metals and heavy industry deals with similar load and floor issues.
Utility make-ready and the vehicle delivery date
Vehicle programs run to delivery dates that do not move easily. A fleet that has ordered electric buses or vans needs the depot ready before they arrive, and a supplier that has accepted a launch date needs its line running by then. We schedule backward from the delivery or launch date and highlight the utility make-ready work, switchgear lead times and charger delivery as the critical items. Early release of long-lead equipment and a utility application filed in preconstruction are the two best ways we know to protect the date.
We also stage the work so that the fleet can operate during construction. Parking is relocated in phases, charging zones are brought online as they are finished, and shop work continues on part of the building while another part is renovated. A written plan for vehicle movement, fueling and access keeps drivers, technicians and construction crews apart and keeps the operation running.
Send the vehicle count, the charger plan and the utility letter
Share the fleet size or the plant line list, the charger or process load you expect, any utility correspondence and the delivery or launch dates. We will return a site plan approach, an electrical coordination checklist and a schedule that shows the utility steps beside the construction steps.
Common Questions
How do we size electrical service for a charging depot?
Start with the number of vehicles, the daily energy each uses, the charging window and the charger power, then confirm the result with the utility. Managed charging, which staggers vehicles during the night, can reduce the peak and the service size. We help owners build a few scenarios so the utility conversation starts with real numbers.
Do EV and battery areas need special fire protection?
They often do, and the requirements depend on the jurisdiction, the quantity of batteries and the design. The fire authority reviews the layout, separation, ventilation and suppression, and we involve it during design. We build to the approved design and keep the inspection records.
Can an existing shop be converted for electric vehicles?
Often, with limits. We check the electrical service, the floor, the ventilation and the fire design, and we confirm door heights and bay widths for the vehicles. Some shops need a new electrical room or yard work, and we price those items separately.
What happens to the floor under heavy vehicles and battery packs?
The floor must be designed for the axle loads, the lifts and the equipment, with joints placed away from wheel paths. Battery packs add weight in a small footprint, so storage areas often get a heavier slab section. We take the numbers from the vehicle and equipment suppliers.
How does snow affect charging and fleet yard design?
Snow load affects canopies and roofs, and meltwater affects yard drainage and ice at charger locations. We slope pavement away from chargers, add drains at lane ends and designate snow storage. Where reliability is critical, covered charging is often worth its cost.
