Dock count and trailer court depth decide a distribution center before the first footing is poured. A building that has to turn a set number of trailers per shift needs door positions, apron depth, staging lanes and a gate that keep the queue off the public road, and every one of those is a civil and structural decision. We build distribution centers from that throughput number backward, so the dock wall, truck court and storm system are sized for the operation and then checked against the parcel.
Colorado gives buyers several different freight models to choose from. Aurora Highlands, a roughly 4,000-acre development southeast of Denver, gained a full E-470 interchange at Exit 22 that cost $87 million and opened on June 28, 2024. Monument approved two industrial distribution warehouses in phase 2 of the Falcon Commerce Center, south of Baptist Road and west of I-25, on January 14, 2025. In Fort Lupton, Northland Business Park sold 316 acres on November 18, 2024, including 103 acres of shovel-ready land across 15 parcels.
These are different problems. A site next to a new beltway interchange is mostly an earthwork and drainage exercise. A site on the Palmer Divide has higher elevation, colder winters and a longer frost window. A shovel-ready parcel on US 85 may already carry the utility stub you need, which changes how we sequence the work. Operators serving e-commerce fulfillment face the same site questions at larger scale, and our distribution center expansions service covers the second phase when the first building outgrows its volume.
The scope that sits behind a distribution center
A distribution center is a building plus a yard, and the yard is where schedules slip. The scope includes the dock wall with levelers, seals and dock lighting, a reinforced concrete truck court designed for the static loads of parked trailers and the turning loads of tractors, drive lanes, employee parking, gate and guard house, and the stormwater facilities that serve all of it. The reinforced truck court is a slab system of its own, and we detail its joints, dowels and thickness separately from the building floor. See our truck courts and trailer yards scope for how that is specified.
Inside, the slab carries racking, forklift and automation loads. We confirm the racking vendor's base-plate loads, the aisle widths and any very narrow aisle tolerance with the owner before the slab is poured, because a flatness number that works for a counterbalance truck will not satisfy a guided vehicle. Buildings that pick and pack e-commerce orders add mezzanines and conveyor loads, which we cover under logistics and fulfillment centers. The fire protection design follows the commodity class, the storage height and the rack arrangement, and it has to be reviewed by the fire official before we release sprinkler piping.
Site conditions that change a distribution center budget
The question to ask first is where the water goes. A distribution center produces a large impervious area, and the detention pond, outfall and any downstream easement are often the longest-lead pieces of entitlement. We run the drainage concept in the first pass at the site plan so the pond does not take a developable corner at the last minute. Utility capacity matters just as much: electrical service for conveyors, charging and refrigeration loads, and a water service large enough for a fire pump if the municipal main cannot supply the sprinkler demand.
Pueblo is a useful reference for cost expectations. The city lists the St. Charles Industrial Park, an Opportunity Zone with rail freight access, and states that commercial and industrial construction costs about 10 to 15 percent less than the national average. We treat that as the city's own statement and compare it with the specific site, labor and material conditions before we quote, but it explains why operators evaluating a Southern Colorado distribution site often ask us for a Pueblo option next to a Front Range one.
Reading the corridors: Weld County, the Palmer Divide and the south
North of Denver, Fort Lupton sits where State Highway 52 meets US 85 and continues east to the I-76 and US 6 junction at Hudson. That puts a distribution building within reach of both I-25 to the west and I-76 to the east. Unincorporated Weld County adopted the 2024 International Building Code effective June 15, 2026, with engineered foundation designs required for most new structures, so a Weld County site starts with a structural design for the foundation and not a stock detail.
South of Denver, Monument sits at 6,982 feet on the southern slope of the Palmer Divide, and the Pikes Peak Regional Building Department enforces the 2023 Pikes Peak Regional Building Code in that town. The elevation affects snow load, concrete placement in cold months and the mechanical equipment on the roof, and we account for each in the base schedule instead of leaving them as winter allowances.
Operating next to live trucks during construction
Most expansions happen beside an operating building. Our superintendents separate construction traffic from the live truck court with physical barriers and a written haul route, assign a flagger for every shared crossing and confirm the plan with your yard manager before mobilization. Excavation near operating dock aprons is scheduled around the peaks in your outbound volume, not around our convenience.
Fire protection impairments are the other area where an expansion can hurt an operating site. We submit impairment notices in advance, coordinate sprinkler shutdowns with the insurer and the fire marshal, and limit the number of zones isolated at one time. When a new addition ties into an existing sprinkler riser or fire pump, the test and acceptance record is part of the turnover package we hand to your risk team.
Schedule levers and where the float is
For a distribution center the critical path usually runs through the steel or panel package, the electrical gear and the dock equipment. Switchgear lead times, in particular, can run well past the date the shell is dried in, so we release gear orders during preconstruction through our long-lead procurement management practice. The float we protect is in the interior: racking installation, conveyor setup and the owner's own IT work all depend on a clean, powered, lit and sprinklered building.
We also build in a commissioning period that is separate from construction completion. Dock levelers, door controls, lighting controls, the fire alarm and any rack-supported sprinkler heads are tested and documented before we ask for substantial completion, and the turnover package includes the as-built set and operations manuals organized by system.
Bring us the throughput target
Give us the daily trailer count, the dock door ratio you plan to run and the opening date. We will test the site, the truck court and the structure against that number and tell you where the schedule is exposed.
Common Questions
How much truck court do I need relative to the building?
It depends on the trailer count and the maneuvering geometry, not a fixed ratio. A cross-dock layout (see our truck terminal and cross-dock work) needs depth on both sides of the building, while a single-sided building needs a deeper apron to let trucks back in without blocking the drive lane. We lay out the turning paths with your fleet's actual tractor and trailer dimensions before the site plan is submitted.
Does Weld County require an engineered foundation?
Yes, for most new structures in the unincorporated county under the 2024 International Building Code adopted effective June 15, 2026. That means a geotechnical investigation and a foundation design stamped by the engineer of record. Incorporated towns in the area have their own adopted editions, so we confirm the jurisdiction on the parcel before we price.
What causes the most delay on a distribution center?
Electrical gear and the stormwater approval. Large switchgear and transformers carry long lead times, and a detention design that changes during review can reset the grading plan. We release the gear orders early and bring the drainage design to the reviewer with the first site plan submittal.
Can you expand an operating distribution building?
Yes. We phase the work around your shipping schedule, separate construction traffic from the truck court and coordinate the fire protection tie-in with your insurer. The addition and the existing building often share a roof drainage path and a dock apron, and we resolve those joints in the design.
Are slab tolerances different for automated systems?
They can be. Narrow-aisle and guided-vehicle systems usually need tighter flatness and levelness than a counterbalance operation. We get the vendor's numbers in writing before the slab specification is final, and we test the floor after the pour against that specification.
