01 / Overview

Expanding a live datacenter by 3.8 MW — without a single minute of downtime.

Our client faced a critical deadline to bring a 3.8 MW data hall online within an existing shell space — through a two-phase approach, while maintaining 100% business continuity across their live critical operations.

Phase 1 called for the delivery of 2 MW of new IT load, followed by Phase 2 adding an additional 1.8 MW of high-density server capacity. With committed customer contracts and substantial revenue at stake, any delay or disruption to existing operations would have resulted in significant financial penalties and SLA breaches.

The project demanded Tier III redundancy standards across all disciplines while working within an active, fully operational datacenter. Derrig | Talbot acted as the central coordination hub across all MEP trades, delivering Phase 1, validating full integration with existing systems, and then seamlessly transitioning into Phase 2.
