How TCG Builds Data Centers in Charleston
South Carolina and the broader Southeast have become a meaningful data center market, drawn by available power, land, and growth, and the Charleston region is part of it, with hyperscale investment in the area including a large Google data center in Berkeley County near Moncks Corner. Demand spans enterprise, Tier III and IV, colocation, edge, and the new wave of AI and HPC. Power comes from Dominion Energy South Carolina, Santee Cooper, and Berkeley Electric Cooperative, and speed to power is often the gating factor. TCG builds powered shells, fit-outs, and turnkey critical facilities, and self-performs the IMP envelope.
A critical facility on the Charleston coast has to withstand more than most. Buildings are engineered for high hurricane wind under the South Carolina Building Code, elevated above the FEMA flood zone, and designed for the low-country seismic loads that are a legacy of the 1886 earthquake, all while protecting uptime. Cooling is harder in the hot, humid Lowcountry, where free cooling and economization are limited, so mechanical design leans on efficient, resilient cooling. Redundancy, N+1 or 2N across mechanical and electrical, generators, UPS, and switchgear, is engineered to the target tier, and soft Lowcountry soils frequently require deep foundations. See data center and critical infrastructure, in-house MEP, and structural.
We run design-build with in-house architecture and engineering, which gives owners schedule certainty and a single point of accountability on projects where every week of delay is expensive. We self-perform FM-rated IMP envelopes, fast, efficient, and wind-rated, and bring direct manufacturer relationships to long-lead equipment procurement. See the data center cost guide and the data center boom.
Charleston Data Center Construction Cost
Data center cost depends mostly on IT load and redundancy tier, and is often quoted per megawatt: a Tier III facility commonly runs about $9M to $15M per MW all-in. Per square foot, ranges run from a powered shell to a high-density AI build. Use the estimator above and the national data center cost guide for context.
TCG Builds Across the Carolinas
Charleston is the TCG hub for the South Carolina Lowcountry. We deliver design-build commercial construction across the Carolinas, including Columbia, Charlotte, and Raleigh, and reach the rest of the Southeast and all 50 states from there.

300,000 SF Data Center Support Campus, North of Dallas
TCG erected and insulated three 100,000 SF pre-engineered metal buildings for the staging and storage campus of a new data center north of Dallas, Texas. Building 1 went from start of steel erection to sign-off in 41 days, and the full campus finished 30 days ahead of schedule.
On a data center campus the support buildings come first: staging, equipment storage, and laydown have to be dried in before long-lead electrical and mechanical gear arrives for the data hall. Crews ran early morning and night shifts under light towers, with roof panels, wall cladding, and insulation moving in parallel instead of in sequence.
TCG brings the same schedule-first crews and PEMB and IMP self-perform capability to data center projects in Charleston.
- Scope: PEMB steel erection, roof and wall panels, and insulation
- Use: staging and equipment storage for a new data center campus
- Schedule: parallel crews on extended shifts
- Result: 300,000 SF delivered 30 days early

Charleston Data Center Construction FAQ
Common questions about data center construction in Charleston and the Lowcountry. See the full TCG FAQ for more.
TCG most recently erected and insulated a 300,000 SF data center support campus north of Dallas, Texas: three 100,000 SF pre-engineered metal buildings for a new data center’s staging and storage campus. Building 1 went from start of steel erection to sign-off in 41 days, and the full campus finished 30 days ahead of schedule in fall 2026. TCG brings the same crews and self-perform capability to data center projects in Charleston.
Data center cost depends mostly on IT load and redundancy. A Tier III facility commonly runs about $9M to $15M per MW all-in. Per square foot, a powered shell is $160 to $350, enterprise or Tier II $700 to $1,200, Tier III colocation $900 to $1,500, and AI or HPC high-density $1,100 to $2,000. Use the estimator above and the national data center cost guide.
Powered shells, enterprise data centers, Tier III and IV facilities, colocation, edge, and AI and HPC builds, as shell, fit-out, or turnkey. We engineer the mechanical, electrical, and structure in-house and self-perform the IMP envelope. See data center and critical infrastructure.
Yes. South Carolina and the Southeast have drawn significant data center investment for power, land, and growth, and the Charleston region is part of it, including a large Google data center in Berkeley County near Moncks Corner. Demand spans enterprise, colocation, edge, and AI and HPC. See the data center boom.
Power comes from Dominion Energy South Carolina, Santee Cooper, and in some areas Berkeley Electric Cooperative, and speed to power, securing utility capacity and the substation timeline, is often the gating factor on schedule. We coordinate utility engagement early so the power path is not the thing that delays energization.
A critical facility on the coast is engineered for high hurricane wind under the SC Building Code, elevated above the FEMA flood zone, and designed for low-country seismic loads from the 1886 legacy, all while protecting uptime. We coordinate the envelope, structure, and flood elevation with the redundancy design from the start.
The hot, humid Lowcountry limits the free cooling and economization that drier or cooler climates use to save energy, so the mechanical design leans on efficient, resilient mechanical cooling sized for the load and the climate. We engineer the cooling in-house and design it for the target tier and density.
Redundancy, N+1 or 2N across mechanical and electrical, generators, UPS, and switchgear, is engineered to the uptime tier the owner needs. Tier III is concurrently maintainable and Tier IV is fault tolerant. We design the systems and the structure to that target and coordinate them so the facility actually achieves the tier.
Yes. FM-rated insulated metal panels give a data center a fast, efficient, wind-rated envelope, and we self-perform IMP with more than 1 million SF installed across 38 states. On the coast that wind-rated envelope is part of the resilience strategy. See IMP installation.
Schedule certainty and a single point of accountability. On a facility where every week of delay is expensive and power, cooling, structure, and the envelope all interact, having the designers and builders on one team reduces risk and change orders. See what a design-build contractor does.
