Distribution Center Construction in Denver, Colorado

Truck count decides the layout of a distribution center before racking does. A building that turns a few hundred pallets a day on a handful of doors is a different animal from one that dispatches trailers around the clock, and the slab, the dock wall and the court all follow from that number. We start every distribution project with a throughput conversation, then draw the footprint backward from the doors.

The north metro is where the volume is going. Crossroads 25, at the northeast corner of I-25 and E-470 in Thornton, is a 76-acre, six-building industrial park of 1.1 million square feet, with phase one of 828,000 square feet scheduled for delivery in the third quarter of 2027. Nearby, Rockefeller Group bought 35.6 acres at East 152nd Avenue and Washington Street in September 2023 for 25 Commerce Park, a three-building, 453,550 square foot project. These are the parcels that set expectations for clear height, car and trailer parking and how fast a shell has to turn over to a tenant.

We build the whole package: grading and utilities, the structure, the dock wall and the pavement. If you are weighing a distribution building against a logistics fulfillment center, we can price both against the same parcel and give you the cost per pallet position for each.

Dock wall, slab and the first 200 feet of the site

Most of the money in a distribution building sits in three places: the dock wall, the slab and the court in front of it. The dock wall carries doors, levelers, bumpers, lighting and a canopy or seals, and any one of those missing from the structural drawings becomes a field change. We coordinate the dock package with the equipment supplier before the foundation is poured so pits, embeds and edge angles are set once.

The slab is designed for forklift traffic and high-density racking. Joint spacing, dowelling at construction joints and floor flatness tolerances matter more here than in a storage shed, because a very narrow aisle truck needs a flat, level surface to run safely. We pair the slab with the court design: reinforced concrete at the dock aprons, heavy asphalt or concrete in the drive lanes, and a stormwater plan that does not push water toward the doors. Our distribution center expansion experience helps when a building must be extended without stopping the flow.

Highway, rail and airport access that tenants pay for

Commerce City reports two Class I freight rail lines, sits where three major interstates meet and is directly adjacent to Denver International Airport. In Thornton, Interstate 25 passes through the city twice and E-470 runs through its north side, and the E-470 interchange at Quebec Street opened November 24, 2014. Between them the north metro gives a tenant truck access to the whole Front Range without running the downtown grid.

Amazon announced in June 2017 an 855,000 square foot, three-level fulfillment center near I-25 and 144th Avenue in Thornton with 1,500 full-time positions, a reminder that large operators already treat this corridor as a staging area. That demand shapes what other tenants expect: car parking for shift workers, trailer positions and a clean entrance onto an arterial. We bring those expectations into the site plan and tie them to ecommerce fulfillment requirements when the tenant is a parcel carrier or online retailer.

Site conditions that surprise out-of-town developers

The South Platte River valley, its tributaries and long-established drainage ways affect parcels throughout the metro. A site that looks flat can sit in a floodplain, and Commerce City's local amendments reference a FEMA flood hazard map study from 2007. We review drainage, floodplain status and detention requirements during due diligence, not after you close, and we tell you what each one adds to the budget.

Utilities need the same early look. A large distribution building draws significant electric load for lighting, charging and, increasingly, truck and equipment electrification, so the utility's service timeline can run longer than the shell. Where a rail spur or a second access road is on the table, we pull in the rail spur site improvements team in the first month so the track geometry and the truck court do not compete for the same ground.

Managed work that protects the schedule

We manage closely the work that controls a distribution schedule: site grading, underground utilities, concrete flatwork and the slab. We schedule and inspect the trade partners who place, finish and cure the floors and aprons, and one team is responsible for the dock pits, the leveler embeds and the court elevations. That avoids the argument over whose tolerance was off.

When the tenant needs more power, we also coordinate underground electrical duct banks, because the conduit pathway should be in the ground before the court is paved and well before the utility energizes the service. Steel, panels, roofing and mechanical scopes are bought from qualified trade partners and managed from our own schedule, which keeps one accountable lead on site.

Services that sit beside the building

A distribution project rarely ends at the shell. Trailer parking, truck courts and employee parking each have a different pavement design and drainage pattern, and we price truck courts and trailer yards as part of the primary scope. Yard lighting, security fencing and access control are layered on once the dock plan is fixed.

If the project is a first phase of a larger program, long-lead procurement management can lock in switchgear, dock equipment and roofing orders for later phases before price and lead times move. Owners who build multiple locations also use our programmatic approach to keep details consistent from site to site.

Delivering a shell on a tenant clock

Tenants sign leases against a delivery date, so the schedule is a commercial commitment. We build the program around the long poles: utility service, precast or tilt panel fabrication, structural steel, roofing and the fire pump. Each has a procurement window, and we place the orders before the permit is in hand when the owner is willing to carry that risk.

Thornton lists the 2024 International Building Code with the 2023 NEC, implemented July 6, 2025, so a permit pulled now reviews against a current edition. We confirm the edition at each jurisdiction before pricing so the structural, fire and energy designs are not redrawn after submission, and we report schedule float weekly so an owner can see which dates actually have room.

Bring the throughput targets

Share your pallet count, door count and growth plan and we will draw a footprint, a site plan and a schedule. If the building will also hold temperature-controlled product, we can evaluate a cold storage facility design alongside it.

Common Questions

How much truck court depth should a Denver distribution building have?

Depth depends on trailer length and how many doors the tenant uses, but a court large enough for a trailer to back in and for another truck to pass behind it is the usual starting point. We confirm turning paths against the actual fleet, not a generic template. A court that is too tight causes damage and delays at every shift.

Can the building be designed for a future expansion?

Yes. We can leave one end wall as a removable panel or a structural frame, stub utilities beyond the first phase and size the dock wall for additional doors. The cost of planning for expansion is small compared with demolishing a finished wall later.

Which Thornton and Commerce City details change the permit?

Commerce City adopts the 2021 International Building Code with local amendments, while Thornton lists the 2024 edition. The two cities review sprinkler design, energy and egress slightly differently, so one prototype drawing set is adjusted for each jurisdiction before submission.

How early should we order electrical gear?

As soon as the load letter is firm. Switchgear and transformers can govern the schedule for the whole building, and the utility needs its own design time. We recommend ordering before the shell is fully permitted if the owner can accept the commitment.

Does the building need rail service?

Only if the product mix justifies it. Rail adds cost in land, track and operations, but a Commerce City parcel with two Class I lines can use it for bulk or heavy inbound product. We compare the rail-served and truck-only options before you commit.
