FiveNines Group has completed the delivery of a 9.6MW hyperscale data centre for an international client, achieving LEED Gold sustainability certification while recording more than 832,000 working hours without a single lost-time incident.
The project marks a significant milestone for the UK-headquartered data centre infrastructure specialist, demonstrating its ability to deliver complex mission-critical facilities under a full general contractor model while maintaining high standards of safety, sustainability and programme execution.
The facility has now received its Taking Over Certificate (TOC), confirming successful completion and handover to the client.
Designed to meet LEED Gold standards, the project incorporated stringent sustainability requirements covering energy efficiency, water conservation and material selection. The completed facility is designed to operate with a Power Usage Effectiveness (PUE) target of approximately 1.16 and a Water Usage Effectiveness (WUE) target of 0.03 litres per kilowatt-hour.
During construction, the project reached a peak workforce of 560 people and accumulated more than 832,000 working hours while maintaining zero Lost Time Incidents (LTIs). The project also recorded an Accident Frequency Rate (AFR) of 0.21.
FiveNines credited its safety performance to a combination of proactive leadership, workforce engagement and occupational health initiatives. These included daily ‘Golden Hour’ leadership safety tours involving environmental, health and safety teams alongside project management, a Positive Safety Recognition programme, and employee wellbeing initiatives designed to encourage early intervention and support.
Chief Executive Officer Gerry Curran said the successful delivery demonstrated the company’s capability to execute major international infrastructure programmes.
“We are delighted to have successfully delivered a data centre in partnership with an international client. This milestone demonstrates the capability of FiveNines to execute complex infrastructure projects while maintaining exceptional safety and environmental performance.
“I’d like to thank our project team and supply chain partners for their commitment and professionalism.”
The project also made extensive use of Building Information Modelling (BIM), collaborative design development and constructability optimisation to coordinate delivery across multiple disciplines. FiveNines said these digital delivery processes helped support successful commissioning and operational readiness ahead of final handover.
A Project Management Perspective
Data centres remain among the most demanding assets to deliver, requiring tight coordination across civil works, mechanical and electrical systems, commissioning, sustainability targets and operational readiness, often within highly constrained programmes.
This project demonstrates that delivery success increasingly depends on integrating digital project management with robust health and safety leadership. Advanced BIM coordination, structured commissioning programmes and collaborative planning have become essential tools for managing the complexity of hyperscale facilities.
The safety statistics are particularly notable. While zero lost-time incidents are an important achievement, sustaining that performance across more than 830,000 working hours with a workforce peaking at 560 people suggests a mature project culture where safety is embedded into daily delivery rather than treated as a compliance exercise.
Equally significant is the combination of sustainability and programme certainty. Achieving LEED Gold certification while delivering on schedule reflects the growing expectation that environmental performance should be managed as a core project objective rather than an additional requirement.
As investment in AI, cloud computing and digital infrastructure continues to accelerate globally, clients are increasingly looking for contractors that can consistently deliver mission-critical facilities with predictable outcomes across safety, sustainability, schedule and operational performance. This project illustrates how integrated project management practices are becoming a key differentiator in that market.
