Flex and Light Industrial Construction in Amarillo

A 190 acre tract east of the City View housing district in Randall County, with BNSF rail access, Loop 335 close by and city water and sewer available, drew a $3.5 million board vote from the Amarillo Economic Development Corporation in 2019 because the CenterPort park in east Amarillo was approaching full development. That decision tells a developer what flex and light industrial users look for: rail or highway reach, utilities already at the lot line, and room for trucks.

Flex buildings are the in-between product. They are part warehouse, part shop and part office, usually divided into bays that can be leased or sold to different users. A plumbing supplier, a small fabricator, a distributor with a showroom and a service company with a yard can all use the same shell. We build these buildings as shells for developers and as finished space for owners and tenants.

The goal is flexibility without waste. We design the bay width, clear height, door count and power service so a tenant change does not require tearing out slab or services. The budget stays honest because we price the shell and the tenant finish separately.

A flex project usually has three layers. The first is the building shell: foundations, slab, exterior walls, roof structure and a basic mechanical and electrical service. The second is the demising system, the walls that separate bays and the plumbing and electrical stubs for each. The third is tenant finish, which varies by user.

We can deliver any layer or all three. Developers who lease on speculation usually want a completed shell with a warm-shell finish and stubbed utilities so they can close a lease quickly. Owner-users want a finished building with office, shop and storage zones. Either way, we tie the structure to the likely use. Our pre-engineered metal buildings are the most common frame for flex, and tilt-wall construction fits larger, taller developments.

The walls between bays deserve their own attention. Demising walls usually need a fire rating and sound control that a tenant will not tolerate losing, and inside Amarillo city limits the 2021 building and fire codes, in effect from January 2024, set the rules. We confirm the rating with Building Safety before drawings are issued, and we build the walls to the roof deck so a tenant's smoke, noise or sprinkler problem stays in that tenant's bay. Fire sprinkler design is coordinated with the likely storage heights rather than the lightest possible use, since a tenant who changes use should not trigger a retrofit.

CenterPort Industrial Park was described in a 2022 profile as 440 acres of industrial land with two rail lines, direct interstate access and high-capacity utilities, and the BNSF intermodal facility there handles about 30,000 containers and trailers a year. The same profile describes a south Amarillo business park of 195 acres of shovel-ready land near I-27 and Loop 335. A 2019 report on Amarillo industrial real estate noted that a beef packer bought 100 acres in the south park for a new facility, which shows the mix of tenants that settles near each other.

For flex, the lesson is location within the location. A bay with rail frontage serves one kind of tenant. A bay near Loop 335 serves another. We help developers walk the sites and match the building plan to the likely buyer pool.

The most common product is the multi-bay light industrial building with grade-level doors and a small office finish in each unit. Some owners want a showroom front with a shop behind. Others want a larger building with a mezzanine office. All of them are cousins of the flex and light industrial category, and the larger versions overlap with warehouse construction.

We also build small manufacturing and assembly spaces inside flex shells, with extra power, compressed air stubs and floor loads for light equipment. The key is to identify those needs while the slab is still on paper, because adding them later is expensive.

Clear height and bay depth set the size of the structure. Door count and dock equipment add cost per bay. Utilities drive the schedule more than the budget in many parks, because extending a water or sewer line to a lot that is not yet served can add months and a large sum. That is one reason the 2019 land purchase listed city water and sewer as available.

Soil conditions add another line. In the Amarillo area, slab design must account for expansive clay in places and shallow caliche in others, and playa lake floors that pond water for long periods. We ask for geotechnical data early and carry an allowance until the report arrives. Drainage and detention can take real acreage, so we show the cost of site area as well as building area.

We start by asking who the tenant is. If the answer is unknown, we design a conservative shell with room to grow. If the tenant is known, we customize. We then price through preconstruction estimating and lock in the metal package, doors and electrical gear early, because those items set the build time.

During construction we focus on a short, predictable schedule. Flex buildings should not drag, since rent starts only when the tenant takes occupancy. We hold weekly progress meetings with the developer or owner and publish a three-week look-ahead so brokers can tell prospects an honest move-in date. When wind, cold or hail forces a change, we report it the same day.

Tell us the tenant types you expect and the park you are considering. We will give you a clear price range and schedule. Developers can also read how we work with commercial real estate developers from land to lease.

How many bays should a flex building have?

There is no best number. The right layout depends on the tenant pool, the site width and parking. Smaller bays rent to smaller users and can lease faster, while larger bays suit distributors. We draft two or three layouts and price each so you can decide with real numbers.

Is rail access worth designing for?

If the user ships bulk or heavy goods, yes. Rail-served parks such as the one east of Amarillo give tenants an option that road-only sites lack. For light, parcel-based users, highway access matters more. We help you judge which type of site fits your intended tenant.

Can I finish only part of the building at first?

Yes. A common approach is to complete the shell and finish a few bays, leaving the rest as warm-shell space. Utilities are stubbed so later finish work does not disturb finished tenants.

What slab do flex tenants need?

Most need a slab that handles forklift traffic and light racking. We generally design for the heavier use because it is hard to improve later. Joint layout and curing are part of the plan.

Does utility availability change your schedule?

It can. A lot with water and sewer at the property line moves fast. A lot that needs a line extension may take longer, and we show that as a separate path in the schedule from day one.
