Colocation data center construction in Texas: multi-tenant shells, electrical backbone, suite-by-suite fit-out and carrier-neutral meet-me space.
Tenants in a colocation hall judge the building by what it lets them do on day one: rack the first cabinet, cross-connect to a carrier, and trust that the power behind the cage will not change under them. A colocation operator in Texas is selling that confidence by the cabinet or by the megawatt, so the building has to be built in sellable pieces, each with its own electrical path, its own cooling and its own access control.
We work back from that commercial unit. The hall, the electrical room, the mechanical gallery and the meet-me entrance are the pieces a salesperson can point to, and the shell, the slab and the site are what make those pieces deliverable in sequence. Where a hyperscale campus is built for one tenant, a colocation building is built for many, and the construction plan accounts for tenants moving in while the next suite is still under construction.
The City of Dallas describes itself through its location: converging railroads, interstate highways and DFW Airport created a major inland port, and the Dallas-Fort Worth metro is the largest inland metropolitan area in the country without a navigable link to the sea. For a colocation operator the same convergence matters in a different way, because long-haul fiber follows rail and highway rights of way and the carriers that terminate there are the reason enterprise tenants want to be nearby.
Master-planned logistics districts offer another route. AllianceTexas is a 27,000 acre development in Fort Worth with industrial, corporate office and aviation uses, which gives a colocation buyer large, graded parcels with utilities nearby. Our Alliance Fort Worth page describes the site conditions in that corridor, and the Dallas market page covers the urban infill case where an existing building is converted instead.
A colocation shell is usually a two or three story concrete or steel building with a ground floor for electrical and mechanical rooms and upper floors for halls, or a single story building with a long mechanical yard along one side. Either way, the structural grid is chosen so that a hall can be divided into suites of different sizes without moving columns. Floor loading, slab flatness and ceiling height are set for the densest tenant the operator expects to sign.
The electrical scope is large and modular: utility service, medium-voltage switchgear, UPS and battery rooms, and distribution to each hall by independent paths. Our colocation data center construction service builds that backbone first and leaves the tenant-specific fit-out for later, so that data hall fit-out space can be finished against a signed lease instead of a speculation.
Texas Local Government Code Sec. 214.216 sets the International Building Code as the municipal commercial baseline, and cities add amendments by ordinance. Dallas, as one example, lists the International Building Code and energy code with its own amendments and the National Electrical Code. A colocation building also draws fire review because of its battery rooms and gaseous or pre-action suppression, and the occupancy classification can shift when tenants bring in different uses.
We obtain the edition and amendment list for the jurisdiction before design is frozen, so that the electrical room clearances, egress distances and fire separation between suites follow the right text. Where the building is in a city, we meet the building official early; where it is not, we confirm which authority actually reviews the project.
Cost in a colocation building is dominated by the electrical and mechanical plant, not the shell. The shell budget moves with structure type, number of stories and site conditions, while the plant budget moves with the redundancy level the operator promises tenants. We separate the two in our estimates so the owner can see the price of a higher tier before it is written into a lease.
Other drivers are quieter. A tenant demand for custom suites can add rework in finished work, and a late change in cooling approach changes pad size and pipe routing. We hold a design freeze date for the common backbone and price tenant changes as discrete adds, which keeps the base building on schedule while the leasing team continues to sell.
Our customers include colocation and wholesale operators, the developers who assemble their sites, and the enterprise and network tenants who occupy the halls. Each group asks the builder different questions: operators want delivery dates and tier documentation, developers want land costs and utility timing, and tenants want to know how construction in the next suite will affect their operations.
Those tenant questions are why we pay attention to dust, vibration and noise control, and why we keep a clear separation between the active hall and the construction zone. A carrier-neutral facility depends on trust that the cross-connect room is untouched, and our carrier hotel and meet-me room guidance explains how that room is protected.
Colocation buyers expect diverse paths. That means two electrical feeds from separate utility sources where the grid allows it, and two fiber entrances that do not share a trench, a pole line or a bridge. On the site plan this shows up as two service entrance locations on opposite faces of the building, with duct banks routed so a single dig-in cannot take both. We draw those routes on the survey before the building is placed, because moving a building later to satisfy diversity is expensive.
Roof space is the other limited resource. Dry coolers, chillers and generator exhaust all compete for it or for the yard beside the building, so we reserve expansion pad space for the next phase before the first phase is poured.
Share your tenant mix and phasing. We will price the common backbone separately from tenant suites and show the delivery date for each.
The shell and backbone take about as long as any mission-critical building of similar size, but the clock that matters is the one from lease signing to tenant turnover. We build the common electrical and mechanical backbone ahead of tenants and finish suites against signed leases, which shortens that second clock.
If the operator expects high-density tenants, yes, at least for pipe routes, structural loads and pad space. Retrofitting header routes into an occupied hall is disruptive. We lay out chases and floor loads so liquid-cooled suites can be added without moving existing tenants.
The local building department reviews under the edition and amendments that city adopted, and the fire authority reviews battery and fuel systems. Accessibility registration with the Texas Department of Licensing and Regulation applies to projects of $50,000 or more. We confirm each reviewer before design is frozen.
Sometimes. Clear height, floor strength, roof capacity and utility corridors decide it. Warehouses near fiber routes are attractive, but power delivery and structural upgrades often cost as much as new construction, so we price both before an owner commits.
Large, graded parcels in a master-planned district, with road and utility infrastructure already planned. The remaining questions are power availability and fiber entrance routes, which we evaluate in preconstruction.
