Turner Construction and HOCHTIEF, working with Turner subsidiary Dornan, have been selected by NTT Global Data Centers to build a new hyperscale data center campus in Berlin, Germany, in a contract valued at several hundred million euros.

The award centers on a project that includes a three-story data center with 36 megawatts of IT capacity and a separate four-story office building. Construction began in June 2026.

Project timeline and scope

An integrated delivery team from HOCHTIEF Infrastructure and Dornan is set to carry out the work. Dornan will handle mechanical and electrical systems installation, while the broader project also includes building management and safety systems designed for mission-critical operations.

NTT expects the first operational data halls to be delivered in 2028, with full completion of the project targeted for 2029.

Digital infrastructure demand

The Berlin contract adds to a growing pipeline of large-scale data center construction tied to cloud computing, artificial intelligence, and enterprise digital services. The source article said growing demand for digital infrastructure continues to create major construction opportunities across Europe.

The project also adds to HOCHTIEF's activity in the European digital infrastructure market, where demand for hyperscale and colocation facilities continues to rise. According to the company, data center projects made up a significant share of its 2025 project backlog.

For Turner and Dornan, the contract further expands their portfolio of complex facilities that require specialized construction, mechanical, and electrical expertise.

Market significance
