Critical infrastructure consultancy

Data centre operations expertise, on demand.

Senior, hands-on leadership for critical infrastructure. We help data centre owners, operators, investors and customers run safer, more available and more efficient facilities, including high-density and AI deployments.

With 25+ years running live, business-critical sites, we have led operations across colocation and hyperscale portfolios and led the build, commissioning and handover of new facilities. We work as an embedded interim leader, an independent reviewer, or a strategic adviser, whichever fits your situation.

Talk to us

What we do

Practical support across the full data centre lifecycle, from design review through to live operations.

01

Operational review and assurance

An independent assessment of how a site or portfolio is run: safety, resilience, maintenance regimes, incident handling, staffing and supplier performance. You get a prioritised action plan, not a generic report.

02

Technical and operational due diligence

Support for acquisitions, investments and asset transfers. We assess M&E condition, H&S, operational maturity and the capital upgrades needed, giving decision-makers a clear go/no-go view across multiple sites and countries.

03

Commissioning, IST and operational readiness

We make sure what was designed is what gets delivered, and that your team is ready to run it: factory acceptance and witness testing, Level 3–5 commissioning and IST, snagging, handover and O&M documentation.

04

Operating model and standards

Consistent ways of working across sites: SOPs, MOPs and EOPs, ITIL-aligned change control, permit-to-work, KPI governance and CMMS/DCIM adoption.

05

Incident, problem and resilience management

Escalation frameworks, root cause analysis and corrective action, plus business continuity and DR planning, including black-building and failure-scenario exercises.

06

High-density and AI/liquid-cooled readiness

Plan power, cooling, space and network capacity against sold and forecast demand, and make sure operations are ready to support high-density and liquid-cooled deployments.

07

FM and supplier strategy

Structure, tender and manage outsourced FM and OEM relationships: RFPs, SLAs, critical spares strategy and supplier performance management.

08

Interim operations leadership

An experienced Director/VP-level leader who can step into a live operation, stabilise it, set direction and hand over cleanly, whether the gap is a vacancy, a transition or a turnaround.

09

Compliance and safety culture

ISO27001 and other ISO attainment, EHS, CDM and contractor safety management, plus near-miss reporting and a genuine safety culture.
