NTT says it has developed a new prefabricated data center construction method that could cut the time for getting hyperscale facilities up and running.The Japanese company’s Facilities division says that the modular construction method, Hyper Ready Module, uses prefabricated buildings that can be delivered to sites for rapid commissioning. It believes it can have an operational hyperscale data center ready to go in two years, with one year dedicated to planning and design and a second for construction.Large-scale data centers are typically three-to four-year projects, the company claimed.“By standardizing the process from design to construction, NTT Facilities aims to reduce the time required from application and design to construction of large-scale data centers in the tens-to-hundreds-of-megawatt class for hyperscalers by up to approximately 50 percent compared to conventional methods,” an NTT Facilities statement said.Features of the NTT modular design include all cooling and electrical equipment being outside the data center structure, making it easier to prefabricate buildings.Inside, it employs a Design for Manufacturing method, an engineering practice of designing components to optimize their fabrication and assembly. In this case, it means items such as pipes for cooling and electrical wiring will be made in standard-size units, so they can be assembled easily on site. Power supply equipment will also be unitized to reduce the construction period, NTT said.The company intends to work with data center operators so that it can introduce the modular approach for projects in the 2028 financial year.“NTT Facilities will present an ideal data center vision from multiple perspectives, including addressing the high heat generation and high density of data centers, achieving carbon neutrality, and harmonizing with local communities,” the statement added.Modular data center construction is not a particularly novel concept, though it is more commonly used for small installations, rather than gigawatt-scale campuses.
