Warehouse and distribution center construction planned around the truck court

Choosing a warehouse site

In warehouse construction, the best time to test a site is before closing. AP’s development consulting work checks a tract against the building the operation needs, so the owner buys land that fits. Five questions decide it: what zoning allows, how trucks reach it, how much of it the building can use, what lies under it, and where its water goes.

Zoning has to allow warehouse or industrial use, and some cities also limit outdoor trailer storage or docks facing a street. If the tract is not platted, or the plat does not match the planned lots and easements, platting becomes its own approval with its own clock.

Frontage decides where driveways can go. Loaded tractor-trailers need a legal route from the highway to the gate, a driveway the road owner will permit, and enough distance from intersections to turn in safely. A low-priced tract on a road trucks cannot use is not a bargain.

The building only uses part of the land. Truck court, trailer parking, car parking, setbacks, landscaping, and detention take the rest, and a site sized by building area alone often cannot hold the court the docks need. Dishaka fits 108,040 SF of building on nine acres with truck access and drainage worked out on one plan.

A geotechnical report sets the slab and foundation design, and expansive clay or soft fill adds cost under the building and the paving. Detention rules and floodplain lines can take usable acres off a tract.

Site access and circulation

The site plan starts at the public road. A distribution building needs a truck entry that handles the turning radius of a full tractor-trailer, a queuing lane that keeps trucks off the street at shift change, and a court deep enough for trailers to back into the doors without crossing the drive aisle. Employee parking, visitor access, and any outbound van fleet have to be separated from that loop.

We check the circulation against the operator’s actual trailer count and peak hours, not a template, and we plan trailer staging and drop lots where the operation needs them. On a nine-acre site such as Dishaka the balance between building footprint, court, parking, and detention is set once, early, because every later change moves everything else.

Shell, spec, and owner-occupied warehouses

The first program question is who the building is for. A speculative warehouse goes up before a tenant signs. An owner-occupied or build-to-suit warehouse is built for one known operation. That answer changes the slab, the power, the office, and the docks.

A spec shell is built for the widest range of likely tenants. It typically includes the structure, roof, slab, dock openings, a sprinkler system, and base electrical service, with a small spec office or none. Interior finishes, most dock equipment, and tenant power wait for a tenant improvement once a lease is signed.

Because nobody knows the tenant yet, the shell has to anticipate. Slab thickness, clear height, and sprinkler design decide which tenants the building can serve, so they are set for the market the owner expects to lease to.

An owner-occupied warehouse is designed around one rack plan, one commodity, one dock schedule, and one office program. The slab is detailed to real rack post loads, power is sized for real equipment, and dock equipment is bought with the building. Dishaka shows the result: office, production, and warehouse planned together for one business.

Tenant improvements in a spec building need their own permit. If a tenant stores higher, or stores a different commodity than the shell assumed, the sprinklers may need to change. Settling those assumptions in the shell keeps the later work small. The economics of build-to-suit and leasing are covered on the design-build page.

Docks and doors

Dock count, spacing, and position follow the inbound and outbound flow. Cross-dock operations want doors on both long walls; a fulfillment operation may load out one side and receive on the other. Each door carries a leveler, seal or shelter, bumpers, and lighting, and grade-level doors for vans and box trucks need their own ramps and approaches.

Dock equipment is a long-lead item. Door and leveler packages are selected in preconstruction so the slab depressions, pit dimensions, and electrical rough-in are right the first time.

Clear height and slab

Clear height sets the storage cube and drives the cost of the structure, the sprinkler system, and the lighting. AP prices clear-height options during estimating so the owner sees what an extra four feet buys and what it costs.

The slab carries the racking, the forklifts, and in tilt-wall construction, the wall panels themselves during casting. Thickness, reinforcing, joint layout, flatness tolerance, and cure timing are set against the rack plan and the panel schedule. A slab poured before the racking layout is known is a slab that gets cut and patched later.

Why tilt-wall

Tilt-wall is the dominant system for warehouses in Texas for good reason. Panels are cast flat on the floor slab, then rigged and tilted upright in sequence, so a footprint becomes an enclosed perimeter in days rather than months. The result is a durable, low-maintenance wall with good thermal mass and a clean architectural finish at the office corner.

The trade-off is that the early schedule is unforgiving. Slab placement, panel casting, cure, and crane sequencing have to be planned to the day, which is exactly the kind of coordination AP does in preconstruction. Dishaka was delivered this way.

Envelope, roof, and daylight

The envelope decides what the building costs to run. A warehouse has a large roof and long walls, so each choice repeats across a lot of area.

Roof insulation pays off even in an unconditioned warehouse, because it cuts the heat that reaches the floor, the workers, and the product in a Texas summer. A conditioned or partly conditioned building needs walls, roof, and dock seals that work as one system, and the energy code sets minimums for that space. Tilt-wall panels can be insulated on the inside or cast as sandwich panels.

Most warehouse roofs are low-slope: a single-ply membrane over insulation on a steel deck, or standing-seam metal on a metal building. Slope, drainage, and the number of penetrations decide how long the roof lasts, and coastal wind zones raise the attachment requirements.

Skylights and clerestory windows bring daylight to the floor and can cut daytime lighting load. They are laid out around rack aisles and sprinkler heads, and smoke vents may be part of the fire design. If any part of the building will be refrigerated, raise it at the start, because it changes the envelope, the slab, and the power.

Utilities, drainage, and fire protection

Fire protection is often the hidden schedule driver. Commodity class and storage height set the sprinkler design, and that design can require larger water service, a fire pump, a tank, or all three. Each has its own permit review and lead time. We confirm available water pressure and flow early and get the fire protection engineer into the first design meetings.

Power service, transformer placement, and gas are confirmed with the utilities before the building is fixed. Drainage and detention are sized for the full site including future expansion, so the second building does not require rebuilding the pond.

Office and warehouse balance

Most warehouses carry an office component, and on a production or fulfillment building it can be substantial. Dishaka pairs 17,040 SF of office with its production and warehouse space. The office needs its own mechanical, electrical, and life-safety systems, a finish level that differs from the warehouse, and a position on the site that keeps staff and visitors out of the truck loop. We plan it as part of the building rather than a box attached to it.

What drives warehouse cost

Owners often ask what a 50,000 SF warehouse costs. The useful answer is a method, because the same floor area can carry very different budgets. These are the drivers we price.

Building cost scales with floor area. Site cost scales with acreage, soils, and the road. Truck court paving, drainage, detention, and utility extensions can take a large share of the total, because heavy paving covers much of the land.

Structure comes next. Tilt-wall suits larger footprints and gives a durable concrete wall. A pre-engineered metal building reaches enclosure with fewer trades, and more owners now price it first. Each foot of clear height adds wall, structure, sprinkler, and lighting cost. Each dock position adds a door, a leveler, a seal, bumpers, and paving. Slab thickness and flatness follow the rack loads.

Fire protection is often the largest single system, especially when it needs a fire pump or water storage. Office space costs far more per square foot than warehouse space, so a building with a large office prices very differently from one that is mostly storage.

The instant estimate gives a planning range for the building alone. Its warehouse type assumes a tilt-wall shell with docks and a modest office, and it adjusts for 31 markets in Texas, Louisiana, and Oklahoma, for size, with 50,000 SF and up in its own band, and for soils, travel, and coastal wind. It excludes land, site development beyond the building pad (paving, drainage, detention, retaining, landscape, irrigation), offsite utility extensions, impact and permit fees, design fees, survey and platting, testing and special inspections, owner-furnished equipment, contingency, and financing. Preconstruction prices the site and the building together.

Permits and approvals

A warehouse clears several approvals, each on its own clock. We map them all in preconstruction and start the slowest first.

The city reviews the site plan for access, parking, landscaping, and setbacks. If the tract needs platting or replatting, that runs alongside it, sometimes with a commission hearing.

The building permit covers structure, energy code, accessibility, and building systems. A spec shell and a later tenant finish-out are usually permitted separately.

The fire marshal reviews sprinklers, fire lanes, hydrants, and alarm. Storage above set heights triggers a high-piled storage review, which asks for the commodity, the storage height, and the rack layout. On a spec building, the owner has to choose the storage assumption the shell is designed for. Stormwater and detention go to the city or county engineer, and a pollution prevention plan is needed before ground is disturbed.

Which track sets the date varies by jurisdiction. On many warehouse sites it is the site plan and platting, because the building permit cannot issue until they clear.

Long-lead components

On a distribution center the items that decide the schedule are rarely labor. Switchgear and transformers, roof and joist packages, dock levelers and doors, fire pumps, and specialty panels can each run months from release to delivery. AP flags every one during estimating, confirms current lead times, and sets release dates that protect the operational date. Where release is needed before the construction contract, we say so early.

Commissioning and turnover

A warehouse is ready when it can receive product, not when the roof is on. Sprinkler acceptance tests, fire alarm, doors, dock equipment, lighting, and office HVAC each need testing and sign-off before the certificate of occupancy. On a spec shell, turnover also includes a clear record of the slab, sprinkler design, and power, so the first tenant knows its starting point. AP builds these steps into the master schedule so the final weeks follow a plan.

Speed and future flexibility

Speed to operation is the owner’s return on the building. Preconstruction that settles the site plan, the slab, the systems, and the procurement schedule is what makes a fast tilt-wall build actually fast. Flexibility is the other half: a knockout panel on the expansion wall, utilities stubbed to the future footprint, and a court that still works when the building doubles. Both are easy to plan in and pay for themselves many times over.
