DayOne data center construction to start in Lahti – SRV strengthens its position in the growing market for data center construction 

SRV is launching a data center construction project in Kiveriö, Lahti, for the Singapore-based DayOne. Construction work will begin immediately, and the data center is scheduled to start operations during 2027. 

SRV, Finland's largest business premises builder, has decades of experience in the construction of technically demanding premises. The company believes that the growing data center market offers growth opportunities for SRV, and negotiations are currently underway on several data center projects. 

“With the DayOne project that is now being launched in Lahti and the LUMI AI Factory data center project in Kajaani, which is currently under construction, we are securing a position among the top Finnish data center builders. In demanding data center projects, we can combine our expertise in the implementation of state-of-the-art facilities with high quality and energy efficiency, as well as a high level of occupational safety and responsible lifecycle-wise construction. Our strong project management and our own team of top experts in building systems ensure that we achieve the targets set for the project in terms of quality, budget and tight delivery schedule," says Jarkko Salmenoja, Unit Director at SRV. 

SRV has previously also implemented the Helsinki Data Center for Telia, as well as similar projects in the manufacturing industry that are challenging in terms of building technology, such as Okmetic's silicon wafer factory in Vantaa.  

DayOne is a global data center developer and operator headquartered in Singapore.  

The data center will be built at Ilmarisentie 3 in a former industrial area that has been fully zoned for industrial use. The data center is designed to handle a large amount of data. The data center aims to use energy-efficient technologies and renewable energy sources, and the possibility of utilising the waste heat generated by the operations will be investigated, for example, in local heat distribution.
