Data Center Construction in Port Arthur, Texas

In Port Arthur, the data center competes with LNG trains, refinery turnarounds and a flood-protection program for the same crane operators, electricians and concrete finishers. A builder who ignores that will promise a schedule the labor market cannot deliver. We build hardened compute space for the plants, terminals and public agencies of this stretch of the Texas coast, and we plan crews, equipment and access around the large projects that surround each parcel.

Energy facts explain the setting. The Energy Information Administration, as of January 1, 2026, lists the Port Arthur refinery as the largest in the nation at 656,400 barrels per calendar day, and a second Port Arthur refinery as ninth at 385,000. The Texas Comptroller's 2020 Southeast Texas profile notes that the Beaumont-Port Arthur area is home to the world's largest oil refinery and that Jefferson and Orange counties rely heavily on petrochemical manufacturing.

Below, we explain what that means for a data center and how we prepare for it.

LNG Industry reported on September 24, 2025 that a final investment decision was reached on Port Arthur LNG Phase 2, with nameplate capacity of approximately 13 million tonnes per year, two liquefaction trains and one storage tank, incremental capital cost estimated at US$12 billion plus about US$2 billion for shared common facilities, and commercial operations expected in 2030 for Train 3 and 2031 for Train 4. We cite those figures because they describe the pace of the market: years of heavy construction, then continuous operation for years afterward.

Both stages create data center demand. During construction, contractors need field offices, secure networks and temporary compute. During operation, the plant needs control rooms, historians, safety systems and offsite backup, usually in an edge data center near the plant. Our edge data center construction page lays out the building and the method.

An LNG expansion of this size draws thousands of craft workers to the area. That is good for the region and difficult for a smaller project. We secure our trades early with committed start dates, we prefabricate where we can, and we keep the number of unique trades on site to the minimum the work needs. Offsite fabrication of electrical rooms and skids lets us move labor from a congested site to a controlled shop.

The modular and prefabricated data halls approach suits this setting well: halls are built in a factory, shipped and set on prepared foundations. The site work remains under our supervision, but the hours spent in the field fall sharply. We also use fast-track scheduling where the owner needs the control room live before the plant starts commissioning.

A trade report dated April 24, 2025 says the U.S. Army Corps of Engineers Galveston District awarded a $403.9 million design-build contract on April 9 for Port Arthur flood protection under the Sabine Pass to Galveston Bay program, covering 9,525 feet of floodwall replacements and 2,300 feet of levee raises, with construction expected to begin in summer 2026 and take about three and a half years. The program shows how seriously the area takes surge risk.

The same coastal flooding has been demonstrated by rain. The National Weather Service Lake Charles office lists Port Arthur and Groves among the hardest-hit areas in Jefferson County during Hurricane Harvey, when several refineries took on floodwaters and stayed offline for an extended period. For a data center, the lesson is to stay dry, stay powered and stay accessible. We set pad elevations after a flood review and plan alternate routes for fuel delivery.

Control rooms and safety systems have a design basis, and the data center that supports them must meet it. We begin with the owner's hazard studies and the reliability target, then design redundant power, cooling and network paths to meet it. For plants with blast or toxic release concerns, we coordinate with the owner's engineers on siting, wall construction and air intake locations.

Our integrated systems commissioning is built around the owner's operating procedures. We witness factory tests, run the building through failures of utility power, a cooling loop and a controller, and then train operators on the sequences. This is the best way to ensure that the room will behave properly in a real event.

On a quiet site, labor is a matter of productivity. In a corridor with multiple megaprojects, it is a matter of availability and premium. We therefore carry labor risk as its own line in the first budget, separate from materials and equipment, and we tie it to the schedule assumptions behind it. If an owner moves the start date by a season, the line moves with it, and the owner can see why.

Equipment pricing follows a similar logic. Switchgear, generators and chillers are quoted by vendors with validity dates, and an extension past that date carries a risk of escalation. We help owners decide when to place deposits to hold a delivery slot, since a slot in a busy year may be worth more than a small price difference. Site work, by contrast, can be priced firmly from takeoffs once borings are done.

Industrial districts have their own safety culture, and a data center crew entering one has to meet it. We expect site orientation, gate screening, hot-work permits and restrictions on vehicles and phones in certain areas. Our supervisors attend the owner's safety briefings, and our own plan addresses crane lifts, trenching near live utilities and work at height on the building roof.

Energized work is a separate topic. We schedule tie-ins to live electrical systems for planned outages, with written procedures, lockout and tagout, and a second person verifying each step. A control room data center serves a plant that may not tolerate a surprise trip, so a tie-in plan is reviewed with the operations group long before the outage date.

Port Arthur buyers include plant owners, terminal operators, local government and developers who plan facilities for them. Utilities and power developers are also common, since LNG expansion depends on electrical capacity.

Each group has its own review process. Public agencies may be bound by competitive procurement rules, and the Texas Comptroller's Statewide Procurement Division describes the resources used by state and local buyers. Plant owners usually have their own contractor prequalification requirements. We prepare the documents each one expects, and we are honest about what we can and cannot offer.

Share the reliability target, the load and the plant's schedule. We will outline a building, a pad and a labor plan. You may also want to read about Beaumont and the wider Gulf Coast LNG and petrochemical corridor.

Can a data center project compete for labor with the LNG expansion?

It can if it is planned late. We secure our trades early, use prefabrication and arrange schedules to avoid known peaks. The goal is a realistic plan, not a hopeful one.

Does flood protection change how we design the pad?

The protection system under construction reduces surge risk but does not remove it, and rainfall flooding is a separate hazard. We design the pad on the basis of a flood review and treat protection as a margin. Owners should confirm insurance terms too.

What size of building do plant owners usually need?

Most want a few megawatts or less, in a hardened, single-story building near the plant. The detail depends on the plant's control strategy. We start with the reliability target and work from there.

Is prefabrication a good option?

In a tight labor market, yes. Factory-built electrical rooms and modular halls cut field hours and improve quality control. Site work and the foundation remain in the field.
