Every new data centre that Kapitol delivers with NEXTDC needs to be better than the last, continuous improvement is critical in the competitive data storage sector and central to the vision of both companies.
With demand for data storage far outweighing the available supply, every delay represents revenue loss to the client. With this understanding, value management was approached holistically, with reference to programme, products and construction methods.
Understanding the client’s objectives is essential to achieving this, with NEXTDC’s customer requirements, including Safety, Security (designed and built) and Connectivity providing the basis of all project requirements and decisions.
The COVID-19 pandemic impacts added complexity to procurement lead times, with internationally sourced equipment, including generators, fan walls and switchboards exposed to volatile supply chain conditions. The time margins were razor thin, particularly with extensive testing and commissioning processes reliant on deliveries.
The project included the integration of several firsts for NEXTDC and Kapitol which brought with them several unknowns. This included the RUPs and the fan walls, each requiring a bespoke approach to house and install. The size of the 20-cylinder engine generators was a ‘first of kind’ installation for NEXTDC and Kapitol.
NEXTDC and Kapitol worked closely to remain aware of the challenges and keep ahead of them with innovative responses that offered grounded solutions.
Our Approach
Kapitol commenced on M3 through Early Contractor Involvement (ECI), focussed on getting the project moving sooner and faster. Converting the ECI into a Guaranteed maximum price contract quickened the pace by inviting trade input and aligning engaged expertise between parties. This is essential in data centre construction as the business model relies on clarity, speed and specialised knowledge.
Early design interventions, specifically rationalising the roof structure and reticulating services for the roof plant deck, delivered significant enhancements that improved the programme and safety on site. By changing the electrical switch rooms on the roof from structural steel with fire-rated cladding to a precast system, we reduced the need to work at heights, total workforce hours on site and project costs.
Engaging local manufacturers to prefabricate items such as pump houses, chiller modules, generator modules, and pipe sections, meant that Kapitol was able to devise meticulous craning sequences that were lift-ready once the equipment arrived on site. The local fabrication also allowed the Kapitol team to oversee the manufacturing process, assessing quality and double-checking against specifications. With M3 built to expand, establishing this process enables greater ease when scaling up as new data halls come online.
The extensive commissioning and testing that was required, demanded flexibility with the need to fit around the availability of others. A conscious effort was made to avoid a backlog at the end of the project by testing throughout. The process was highly interconnected, NEXTDC selected the subcontractors for testing and Kapitol supported them to undertake their work – be it at weekends or overnight. With programmers for some systems located in different timezones, fault finding and resolving required and received around-the-clock rostering. Overall, the M3 project achieved an Integrated Systems Testing (IST) load of 4.55MW, representing the highest resilience level for NEXTDC to-date.
The M3 project achievements demonstrate how collaboration has enabled ideas to become reality. In working so closely, fit-for-purpose solutions were formulated that will carry over and contribute to the logic of future designs and delivery.
