Seattle and Eastern Washington Data Center General Contractor
Washington is one of the most important data center markets in the country. The Eastern Washington corridor around Quincy and Moses Lake draws hyperscale operators with abundant, cheap Columbia River hydroelectric power and a cool, dry climate that reduces cooling load. On the west side, Seattle's position as a global cloud capital (Amazon, Microsoft, Google, Meta) drives demand for edge, enterprise, and colocation facilities.
TCG provides design-build data center construction integrating in-house structural and MEP engineering with self-performed IMP installation and PEMB erection. We coordinate critical power (utility service, switchgear, generators, UPS), precision cooling (CRAC, evaporative, liquid), and the building envelope as one accountable package. See our national data center practice.
How Much Does Data Center Construction Cost in Seattle?
Seattle and Washington data center costs run higher than the national average due to prevailing wage, seismic design, and long lead times on switchgear, transformers, and generators. Eastern Washington can be more competitive on land and power, but mechanical and electrical scope dominates the budget in every case.
| Project Type | Seattle Cost Range |
|---|---|
| Data center shell only | $180-$420/SF |
| Enterprise data center | $360-$750/SF |
| Tier III data center | $650-$1,500/SF |
| Powered shell (Eastern WA) | $160-$360/SF |
| Critical power and cooling fit-out | $900-$3,000/kW |
Switchgear, transformer, and generator lead times are the single biggest schedule risk on any data center. Early procurement is essential. Use our AI estimator above or schedule a call with our preconstruction team.
Why TCG for Washington Data Centers
Speed to power decides data center economics, and that is where design-build wins. By holding structural, MEP, envelope, and equipment procurement under one contract, TCG compresses the schedule and removes the coordination gaps that delay energization. We self-perform the IMP envelope, which gives a vapor-tight, continuous-insulation enclosure that protects sensitive white space in Washington's humid west-side climate and dusty east-side climate alike.
Our equipment procurement team manages long-lead critical power gear directly, and our structural engineers design every facility for Seismic Design Category D. Whether you are building a powered shell in Quincy or an enterprise facility in the Puget Sound metro, you get one team accountable from utility service to commissioning.
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 Seattle.
- 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

Seattle Data Center Construction FAQ
Common questions about data center construction in the Puget Sound region. See our full FAQ page 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 Seattle.
Washington data center costs range from $180-$420/SF for a shell, $360-$750/SF for an enterprise facility, and $650-$1,500/SF for a Tier III build. Critical power and cooling fit-out runs $900-$3,000 per kW. Eastern Washington can be more competitive on land and power than the Seattle metro.
The corridor around Quincy and Moses Lake offers abundant, low-cost Columbia River hydroelectric power and a cool, dry climate that lowers cooling load. These factors make it one of the largest hyperscale data center markets in the world, attracting major cloud operators.
Long lead times on switchgear, transformers, and generators. These items can take a year or more and gate energization. TCG manages early procurement through our equipment procurement team to protect the speed-to-power timeline.
Yes. TCG self-performs IMP installation with over 1,000,000 SF installed across 38 states. A vapor-tight, continuous-insulation IMP envelope protects white space from moisture and contaminants, which matters in both the humid Puget Sound climate and the dusty Eastern Washington climate.
Yes. Both Seattle and Eastern Washington sit in seismic zones that require enhanced structural design and equipment anchorage under Seismic Design Category D. This protects critical power and cooling infrastructure and adds 5 to 15% to structural cost.
Yes. TCG provides single-contract design-build with in-house structural and MEP engineering, self-performed IMP and PEMB, and equipment procurement. Design-build compresses the schedule 15 to 30% versus design-bid-build, which directly improves speed to power.
