Data Centre Construction

Delivering certainty for mission-critical infrastructure.

Independent engineering, client representation and commissioning for data centre owners and operators — from feasibility to final handover.

Who we are

We represent the owner's interests on complex data centre projects — so that every facility is delivered as designed and proven before go-live.

Independent of designers, contractors and equipment suppliers, our specialists integrate into client organisations to provide engineering leadership, governance, technical oversight and structured commissioning across Europe, the Middle East and Africa.

Handover & Operational Readiness

A structured transition to operations, so your team runs the facility with confidence and operational excellence from day one.

  • O&M documentation
  • Operator training
  • Operational readiness reviews
  • Project closeout
Standards & compliance

Every project is verified against grid, regulatory and client requirements.

  • TernaGrid connection regulations
  • CEI 0-16MV & HV connection standard
  • CEI 0-21LV connection standard
  • BoDTier level & redundancy strategy
Design to handover

One accountable partner across the full project lifecycle.

Commissioning begins at design, not at the end of construction. Our client-side and commissioning teams work in parallel from day one, so knowledge is never lost between phases.

Commissioning framework

Five levels of verification before go-live.

A disciplined, fully documented process that takes every component — and ultimately the entire facility — through progressively demanding tests, each witnessed and signed off before the next begins.
