Pick faces, conveyor, sortation and mezzanines are what separate a fulfillment center from a plain warehouse, and every one of them leans on the building. A conveyor line wants a flat floor and known column spacing. A pick module wants a mezzanine that can carry racks and people. An order sorter wants a clear span that does not get broken up by a late structural change. We build the shell to carry those systems.
Our clients are operators and developers building for order-driven inventory: parcel, direct-to-customer and multi-client fulfillment. They care about door count, truck access and how quickly the building can be turned over to the equipment installer. We plan for the install crew as a customer of the construction schedule, because a conveyor contractor who cannot get on the floor costs the owner more than a week of delay in the shell.
Oklahoma is a reasonable place for this work. Three interstates meet in the state, and its two largest metros sit close enough to feed a statewide delivery network from a single building.
Operators we build for
E-commerce fulfillment operators come in several forms. Some run a single-tenant building with their own staff and automation. Others lease a bay in a shared facility and need flexible racking and a dock wall that handles both inbound pallets and outbound parcel loads. Our 3PL buildings experience carries over directly, and many clients run a hybrid.
We also serve operators on the edge of the category, such as parts distributors, direct-sale brands and regional carriers. Each has a different parcel profile, but the building questions are the same: clear height, column grid, dock mix, power for equipment and enough trailer parking to keep the yard from jamming.
Where fulfillment sites make sense
A fulfillment center depends on road traffic more than almost any other building type. In Owasso, ODOT is widening US-169 from two lanes each way to three on a two-mile stretch, and daily traffic there has risen from about 60,000 vehicles in 2019 to around 75,000 now. Nearby, the Cherokee Industrial Park offers sites, spec buildings and build-to-suit options, with access to US-75, US-169 and SH-20, Tulsa International Airport and the Port of Catoosa. The location is the point.
In central Oklahoma, the I-40 Crosstown Expressway in Oklahoma City was rebuilt to carry more than 170,000 vehicles per day on at least 10 lanes. Lariat Landing, east of Will Rogers World Airport along I-44, covers over 400 acres and lists air-freight and parcel carriers among its tenants. Those corridors show how air, interstate and truck access come together around the metro. See our pages on Owasso and Oklahoma City for local detail.
Building the shell and the systems around it
Our standard package includes the tilt-wall or metal shell, the slab, a full dock wall, truck court paving, office and break rooms and the electrical service for the owner's equipment. We coordinate openings for conveyor penetrations, lock out zones for sortation and set embeds where equipment frames will bolt to the slab. Mezzanine pick modules are a common add, and we build them as structural steel decks tied to the building design, as covered in our mezzanine and office build-out work.
For last-mile parcel buildings with shorter dwell times and many small vans, we adjust the dock mix and the yard. See last-mile parcel hubs for how those differ from a regional fulfillment building.
Fast turnover for equipment installers
Most fulfillment operators have a hard go-live date tied to a customer contract, so the construction schedule runs back from that date. We commit to key milestones: building dry, slab ready, power energized and fire protection tested. Each milestone releases a trade, and a missed one costs the equipment contractor float they cannot recover.
We also plan for access. Equipment arrives on flatbeds, and the dock wall becomes a staging area for conveyor components. A good site plan sets aside a laydown area and keeps the construction trailers out of the way. If we expect heavy equipment loads, we tell the slab engineer early.
Planning around automation
Automation changes what the floor needs to do. Shuttle racking and goods-to-person systems have flatness requirements that can be tighter than a standard warehouse, and floors need to be tested before the equipment is set. We build the floor to the tolerance the vendor specifies and have it measured. If we cannot reach the number, the owner hears about it before the equipment installer finds out.
We also plan for sprinkler coordination. A rack layout with in-rack sprinklers or plastics storage changes the fire protection scope, and the owner should know that before the storage plan is final. The sprinkler coordination process we use brings the fire protection engineer and the operator together before the steel is ordered.
Services that often come with a fulfillment build
Rack design, dock packages and yards all need to be part of the plan. Rack-supported buildings suit tall, automated storage, and our work on logistics and fulfillment centers covers the core building. If your plan includes a later expansion, we place utilities and slab joints to suit.
Most operators want a clear scope and a clear date. We deliver both in our first proposal, and we revise them honestly as the design develops.
Cost drivers specific to fulfillment
Electrical capacity can be the quiet budget buster. Conveyor, sortation and charging for powered equipment add up, and the utility may need weeks to deliver a larger service. Mezzanine area, clear height and dock count are the next levers, along with the level of finish in the office areas.
We help owners separate the base building from tenant improvements and equipment, so you can compare bids and plan financing. A clean budget structure also makes it easier to shift costs between phases if the program changes.
Share your volumes and go-live date
Send us your order volumes, your equipment plan and a target go-live date. We will build the schedule backward from it and tell you what the shell, the floor and the power need to look like.
Common Questions
What clear height do fulfillment centers typically need?
Most new fulfillment buildings are 32 to 40 feet clear, depending on the racking and automation. Higher clear increases storage density but affects sprinklers, column loads and the cost of building. We price a couple of options so you can see the tradeoff.
Can you build a mezzanine for pick modules in a new building?
Yes. A structural steel mezzanine can carry racks, conveyors and people, and it is easier to include in the base building design than to add later. We coordinate the mezzanine with the sprinkler layout, egress and floor loads.
How tight does the floor need to be for automation?
The vendor will specify flatness numbers, and some systems need very tight tolerances. We build the slab to the specified numbers, test it and report the results before equipment goes in.
How much parking and trailer space is enough?
Count employee shifts, inbound trailers and outbound loads, then add room for peak weeks. Fulfillment sites often need more car parking than a warehouse and more trailer stalls than the owner first expects. We lay it out with your volumes in mind.
Can we start with a shell and fit it out later?
Yes. Many developers build a shell with a dock wall, power stub and clear height, and the operator completes the interior. We identify what the tenant will need, such as extra power or floor load, and decide what to include in the shell.
