The challenge

Our client, a UK-based hyperscale developer and operator, had recently acquired two enterprise data centre sites. They needed a long-term plan to stabilise and upgrade both facilities, while keeping them live and operational.

The challenge: develop a nine-year, £35m refurbishment and cashflow programme with limited design information available. No phasing plan, no temporary works strategy, and multiple competing pressures on the budget. Every pound invested had to be prioritised, sequenced, and justified.

What We Did

We created clear, practical cost models for each workstream, factoring in what it would take to deliver upgrades in live environments, from temporary works to out-of-hours activity. Through iterative cashflow modelling, we optimised annual spend while targeting the assets most in need of attention.

Key actions:

  • Defined scope of works for each site, including alternative solutions to deliver the same benefits
  • Built cost plans and models to support investment decisions
  • Developed cashflow models to balance annual budgets and prioritise critical works
  • Identified and costed temporary works and operational support requirements
  • Benchmarked costs using our sector data to ensure confidence in projections

‍

Unforeseen problems?
Solved fast.

With minimal design information, specifics were hard to lock down. We used our technical experience to identify likely issues early, guide design assumptions, and build robust costings around them. Temporary works, operational attendances, and out-of-hours constraints were factored in, ensuring the plan was realistic and deliverable within live facilities.

The Result

  • Stabilisation roadmap – nine-year investment plan covering all critical works across two sites
  • £35m prioritised programme – cashflowed to match governance gateways and budget availability
  • Optimised solutions – alternative approaches considered to deliver better value outcomes
  • Immediate actions defined – clear next steps for the client to begin stabilisation confidently
    • Lo rendiamo possibile
