Interstate 69E from the Business 77 junction north of Raymondville runs about 53.3 miles through Willacy and Cameron counties to the international border crossing complex, according to the state's highway designation file, and Harlingen sits on that same corridor where it meets Interstate 2. An online seller, a parts supplier or a third-party logistics operator looking at the Valley sees one long highway and a few good places to stand on it. Harlingen is one of them.
A fulfillment center is a warehouse where the main activity is picking individual items and shipping small orders. That changes the building. There are more people inside, smaller packages moving on conveyors, more dock doors for parcel trucks than for pallets, and often a mezzanine for picking and packing. The lighting, restrooms, parking and break areas all grow with the workforce.
We build the shell, the interior systems and the site for these centers, either as new buildings or as conversions of existing warehouses. See warehouse construction for the base building and distribution centers if you handle pallets and full truckloads instead.
Fulfillment projects range from a 20,000 square foot e-commerce operation that grew out of a storefront to a regional hub where several customers share one roof. Each has its own needs. The small operator wants simple racking, a few pack stations and a place to stage outgoing parcels. A shared-user center needs fire separations, tenant demising walls, separate dock access and secure areas for each customer's goods.
Return processing is a growing use. Returned goods need a clean intake area, inspection tables and sorting bins, often at the opposite end of the building from outbound. Our logistics fulfillment center projects page goes further into building types. If your operation includes truck routing for larger freight, a cross-dock layout can sit on the same site.
We ask how an order moves from the dock to the customer: where goods are received, where they are shelved, how pickers walk, where orders are packed and how parcels leave. Walking distance is money, so the building layout is drawn around the shortest path, and we keep the aisles, cross-aisles and emergency exits arranged so a busy shift can move without crowding. The racking layout then fixes column spacing and clear height, and the conveyor layout fixes the floor flatness and any pits or trenches.
Power and data deserve more attention than in a plain warehouse. A fulfillment center may have conveyors, label printers, scanners, wireless access points and sometimes robots, each needing power or network. We run conduit and cable trays during construction, install enough electrical capacity and leave room to add more. For operators who plan to automate in stages, we design the floor and utilities for the end state and equip them in phases.
Climate control deserves a place in the first conversation. A building full of people working at pick stations in a South Texas summer needs real ventilation, large slow fans or air conditioning at the work zones, and good lighting that does not add heat. Full air conditioning of a large floor is expensive, so owners often condition the pack and office areas and ventilate the rest. We show the cost of each choice, and we design the roof, insulation and skylights to help. Employee comfort affects turnover, and turnover is a real cost in this business.
Fulfillment businesses live by the calendar, with a peak season in the autumn when volume surges. A building that opens late can miss it entirely. We work back from your go-live date to set milestones for the permit, the slab, the shell, the racking order and the system installation. We also note which items have long lead times, such as conveyors, sorters and dock equipment.
If you are converting an existing building, schedule is usually faster. We can often finish a floor, lighting, a mezzanine and restrooms in a few months. Phasing allows part of the building to open while the rest is finished, so racking crews, system installers and inspectors can work in turn without waiting for the entire floor, and our phased construction on occupied sites approach keeps a working operation safe next to a construction zone.
Operators often budget for racking and conveyors but forget the building items that support them: electrical service, additional restrooms for a larger workforce, break rooms, fire protection for dense storage, and paved parking. Accessibility is part of that list, because projects costing $50,000 or more must be registered with the Texas Department of Licensing and Regulation for review under the 2012 Texas Accessibility Standards.
Mezzanines are another cost driver. A multi-level pick module can double usable floor area in a given footprint, but it needs a structural frame, stairs, fire protection and code review. The trade partners for structural steel erection build them, and we price them as separate alternates so you can decide.
Valley International Airport extended runway 35L from 8,400 to 9,400 feet by July 2024 so that cargo carriers can fly out at 70 percent of maximum gross takeoff weight, up from about 40 percent before. Fulfillment operators who promise fast shipping will find the airport a useful link. We describe the nearby parcels on our page for Valley International Airport.
The services that support this work include site development and utilities, parking and truck lot paving, security and fencing. Many projects also need commissioning of fire and electrical systems, and our team coordinates it at closeout.
Tell us your order volume, your shift sizes and your target opening date, and we will help you decide whether to build new or convert.
Most pick-and-pack centers use 28 to 36 feet clear for pallet racking and a mezzanine in part of the building. Lower heights work for smaller operations, and the cost increases with height because of sprinklers and structure.
Often yes, and it can save time. We check the structure, the roof, the floor, the fire protection and the electrical service. The main limits are clear height and the number of dock doors.
This depends on your carriers and volume. Many operators use a mix of dock-high doors for trailers and a few ground-level doors for vans. We plan the layout around your pickup schedule.
Specialty vendors install these, and we coordinate the schedule, the power and the floor. We also prepare the slab for equipment bolts and pits.
Parking counts are tied to the zoning and the workforce, and shift changes can overwhelm a small lot. We calculate parking based on your largest shift and test the site layout accordingly. Our logistics and distribution page gives more detail on how we work with these owners.
