International construction services firm Turner Construction Company has more than doubled its data center revenue Year-on-Year (YoY), increasing from $3.6 billion in 2024 to $6.4bn in the first nine months of 2025.

The company, which is now seeing data center construction make up 40 percent of its $40.3bn order backlog, said it expects to deliver $9bn in data center revenue for the full year.

Turner said its backlog represents work for more than 30 clients on more than 250 projects worldwide. The company also delivers semiconductor plants and other AI infrastructure.

“Demand for new capacity remains strong, with data center clients already placing orders for major mechanical and electrical systems scheduled for delivery in 2027,” said Chris McFadden, vice president, Turner Construction Company.

“That level of advance purchasing reflects continued confidence in long-term growth across the sector. Turner is working with clients and suppliers to secure critical long-lead materials and maintain schedule reliability, mitigate supply constraints, and support predictable project execution.”

Turner is a subsidiary of Germany-based construction services firm Hochtief, which is itself majority owned by global construction company ACS.

According to financial results released this week, ACS has had a number of significant new data center projects in the first nine months of 2025.

These include a $15bn data center complex in Wisconsin, part of OpenAI’s Stargate program; a more than $6bn commitment to build a 100MW data center for CoreWeave in Pennsylvania, purpose-built for AI use cases; a high-density, liquid cooling-ready 64MW in Cyberjaya, Malaysia; and a data center in Madrid.

Of these, Turner is working on the Stargate, CoreWeave, and Madrid projects. Dragados, another ACS subsidiary, will also work on the Madrid project. The data center in Malaysia is being built by another subsidiary, Leighton.

The company also noted several new orders in the semiconductor sector, which will be handled by Turner.
