UNDERGROUND DATA-CENTER DEVELOPMENT

A deeper foundation
for digital infrastructure.

Expertise for planning and building underground data centers—with water, energy, local ecosystems, and operating needs considered from feasibility through coordinated delivery.

THE TYPE OF DATA CENTER

Below grade.
Planned around
the workload.

Underground spaces for IT equipment, with power, cooling, connectivity, access, and monitoring considered as one facility.

“Underground” describes the physical setting. The workload, capacity, resilience objectives, and operating model are separate decisions. A suitable project may adapt an existing underground space or develop a new below-grade structure.

Modular phasing is one approach to evaluate. Our proprietary modular concept remains R&D, separate from the project-specific feasibility and development services described here.

PLANNING FOCUS

Establish feasibility before form.

Ground conditions, groundwater, drainage, structure, and permitting require project-specific specialist review. A below-grade setting alone does not establish suitability or resilience.

What evidence is needed to establish a viable site?

Markers identify discussion areas within the concept, not engineered system locations.

01 / FACILITY SYSTEM

Site & structure

Geotechnical conditions, groundwater, drainage, land use, ecological constraints, and structural requirements, evaluated with the appropriate specialists.

02 / FACILITY SYSTEM

Power & connectivity

Utility capacity, power availability and cost, distribution, resilience objectives, network routes, and local infrastructure constraints.

03 / FACILITY SYSTEM

Cooling & controls

Cooling matched to the IT equipment, with water demand, energy use, maintainability, monitoring, and operating controls evaluated together.

04 / FACILITY SYSTEM

Access & operations

Equipment movement, service routes, life safety, maintenance, commissioning, and the people who will operate the facility.

REUSE OR PURPOSE-BUILT DEVELOPMENT

Start with the site.
Keep alternatives open.

The setting must support the intended operation. An underground location alone does not establish lower resource use, resilience, or a viable business case.

ADAPTIVE REUSE

Evaluate what already exists.

Assess an existing mine, cavern, bunker, or other underground structure for a defined workload. Groundwater, structural condition, access, utilities, ventilation, and life safety determine which investigations come first.

NEW BELOW-GRADE DEVELOPMENT

Establish feasibility before form.

For a new structure, coordinate site and geotechnical studies, excavation and drainage questions, surface equipment needs, permitting, and delivery phasing with qualified specialists.

COMPARABLE ALTERNATIVES

Test the case against other options.

Compare an underground approach with viable above-ground retrofit, new construction, or alternate hosting. Use the same workload, continuity, resource, lifecycle, and cost assumptions.

A FEASIBILITY SEQUENCE

Each stage requires project-specific evidence. This sequence is a planning guide, not an engineered design or approval to build.

CONFIGURATIONS TO EVALUATE

The use case
shapes the facility.

These are applications to assess against a project’s site and technical brief. Each calls for a different balance of capacity, connectivity, power, and cooling.

01

Enterprise & campus

A facility around your operations.

Dedicated infrastructure for an organization’s digital operations, with capacity and interfaces shaped around its business or campus requirements.

STARTING POINT

Workload ownership, campus interfaces, and continuity needs.

02

Edge & regional

Capacity close to a defined need.

Infrastructure planned for a service area, connectivity requirement, or local workload. Location follows the network and the demand it needs to serve.

STARTING POINT

Network routes, latency requirements, and local demand.

03

High-density computing

Plan the systems around the workload.

Facilities for demanding workloads, including AI and high-performance computing, with power and cooling requirements established through the technical brief.

STARTING POINT

Equipment density, thermal approach, and power availability.

WHERE OUR EXPERTISE FITS

From the brief
to build readiness.

Underground projects cross disciplines. We connect the requirements, the specialists, and the decisions needed to move the work forward.

01

Define

Establish the project brief.

Workloads, capacity objectives, operating needs, site constraints, utilities, and connectivity.

02

Coordinate

Make the systems work together.

Align facility requirements, specialist scopes, technology interfaces, and design dependencies.

03

Plan the build

Turn the scope into a delivery path.

Construction interfaces, procurement dependencies, phasing, responsibilities, and decision points.

04

Prepare

Plan for life in operation.

Commissioning requirements, documentation, maintainability, operating procedures, and handover.

A SCOPED ENGAGEMENT

Deliverables and delivery responsibilities are agreed around the project’s starting point. Site suitability, engineering, permits, and construction requirements are established through the appropriate specialist work.

Scope, specialist qualifications, and delivery responsibilities are agreed for each engagement. Project-specific engineering, permitting, construction, and commissioning are coordinated with the qualified professionals and delivery parties engaged for the work.

BEFORE THE FIRST CONVERSATION

Start with the
right questions.

You do not need every answer to begin. A clear starting point helps us define the next useful step.

Do we need to select a capacity first?

Share your expected workloads, growth assumptions, and operating requirements. Capacity and phasing can then be evaluated with the site, power, and cooling constraints.

What makes a site suitable?

Ground conditions, groundwater, utility availability, network connectivity, access, permitting, and life-safety requirements all need specialist review. Being below ground alone does not establish feasibility or resilience.

Is the illustration a completed facility?

It illustrates Eco TerraVault’s modular underground research direction. Project-specific engineering, capacity, and performance must be developed and validated separately. Explore the research program ↗

What should we share to get started?

A short description of the intended use, project stage, general location, timing, and known constraints. Detailed facility drawings or sensitive system information can follow an agreed sharing process.
