Cooling Plant and Mechanical Yard Construction in Schertz, Texas

Chilled water systems, cooling towers and the pads and piping that serve them take up more of a data center site than most owners expect, and Schertz offers the room and the roads to build them well. We plan the mechanical yard first, because the water supply, the heat rejection method and the electrical load of the plant fix the size of everything around it.

Exits 174 through 180 of Interstate 35 serve the north side of Schertz, and Interstate 10 reaches the south side by way of a narrow corridor belonging to San Antonio. Those two highways bring chillers, towers and piping spools to the site on standard permitted loads, and they connect the project to the labor and suppliers of San Antonio and New Braunfels.

Water is the second constraint. Cibolo Creek passes just south of the historic downtown and forms the county line separating Guadalupe from Bexar, and its worst recorded flood came in 1913. That history reminds us to set cooling pads, pump rooms and electrical gear above flood levels and to keep discharge from the plant away from the creek corridor.

The yard combines several disciplines. Chiller and cooling plant pads carry the heaviest equipment, cooling water supply and reuse lines bring makeup water and return blowdown, and liquid cooling piping runs from the plant to the halls.

We design the underground first and the pads second. Every pipe, vault and conduit is located, tested and recorded before equipment is set, so there is no digging beside a running plant.

Spare conduits and capped tees are left for expansion, because adding a connection later to a live loop is far costlier than installing it while the trench is open.

Chillers and cooling towers have long manufacturing times, so we release orders at design development rather than after the permit. Delivery dates are linked to when each pad is ready, and receiving crews and cranes are booked in advance.

The sequence inside the yard is fixed: pads and underground, then equipment set, then piping and electrical connections, then flushing and treatment. Each step has a clear inspection, so the commissioning team receives a plant that is ready to be tested.

We also leave time for flushing and chemical treatment, a step that is often squeezed and that determines how long the piping lasts.

A central utility plant concentrates cooling, power distribution and controls for several halls. It is the right choice for a campus that will grow in phases, because new halls connect to an existing loop. A hyperscale data center pushes the same idea further, with a large plant at the center.

Smaller facilities use packaged units on grade or on a roof. We evaluate each option for water use, noise, footprint and maintenance access.

Each choice has a different effect on the site plan and the permit, so the comparison is done before the building is drawn.

Utilities and power developers ask about cooling water demand and discharge because both affect local systems. We help them prepare sizing information and a water plan that uses recycled supply where practicable.

Operators from the cloud and AI market ask about density: how many kilowatts per rack the plant supports and how it expands. We design the loop and the pad layout for later capacity so a new chiller can be added without a shutdown.

Investor backed developers ask a different question, which is how the plant can be split into blocks that match leasing.

The city belongs to the northeast side of the San Antonio region, near Seguin and New Braunfels along I-35. Industrial development is active: the local economic development corporation counts some 8 million square feet of industrial floor area, built or planned, in the city.

That activity means suppliers, haulers and trades already work in the area. A new project draws on them, though it also competes for them, so we confirm availability of specialty piping and rigging firms before pricing.

The retail and dining hub taking shape along I-35 and the military installations around San Antonio also draw on skilled labor, which is another reason to book early.

Cooling plants involve treatment chemicals, large rotating equipment, hot surfaces and confined spaces. We write a plan for chemical handling, lockout, confined space entry and rigging, and we keep it posted at the yard. Pressure tests are done under a written procedure with exclusion zones.

Summer work in South Central Texas means heat stress, so crews take scheduled breaks and heavy lifts are moved to the early hours. Wind limits apply to tower lifts, and lightning stops work until the storm passes.

We start from power and cooling, then work back to the building and the site. For Schertz this means we establish the water source, the plant type and the electrical feed before drawing the building. We schedule, coordinate, supervise and inspect the mechanical, electrical and concrete trade partners to a single plan.

Turnover is part of the scope, not an afterthought. Our integrated systems commissioning work coordinates functional tests, load banks and documentation so the operator can accept the plant with a complete record.

Equipment is the largest item, followed by piping, pads and electrical connections. Water source and discharge can change the budget sharply: a reuse line or a treatment skid adds cost but reduces risk. Soil and flood design affect pad cost too.

We price alternatives side by side, such as air cooled and water cooled plants, and present the operating cost of each over several years. An owner can then see the cost of water against the cost of power before choosing.

Send the load target, the water options and the parcel. We will return a yard layout, an equipment order plan and a commissioning outline.

Why plan the mechanical yard before the building?

The yard determines water demand, electrical load and the area the site needs. If the building is drawn first, the plant often has to be squeezed into leftover space. Starting with cooling keeps the layout efficient and avoids redesign.

How does Cibolo Creek affect construction?

The creek corridor is a flood concern. We keep pads, pump rooms and electrical rooms above the design flood level and design drainage so plant discharge does not add to creek flow. We check floodplain mapping before a parcel is purchased.

What happens during commissioning of a cooling plant?

Commissioning verifies each component and then the system as a whole. It includes flushing and treating the piping, starting the chillers, testing controls and running load banks. We coordinate the tests and keep the records for the owner.

Can the plant be expanded later?

Yes, if the original design includes it. We leave pad space, valved connections and electrical capacity for added units, so a new chiller joins the loop without shutting down the running ones.

Do you use recycled water for cooling?

Where a reuse supply is available and the owner wants it, we design the line, the treatment and the discharge. The choice depends on local supply and permit conditions, and we confirm them with the provider before design.
