YIT will serve as the main contractor and will be responsible for the construction of the data center, including mechanical, electrical and plumbing (MEP) works. The agreement further strengthens the cooperation between YIT and atNorth. In July 2026, the companies announced a contract for the design and construction of another facility at the FIN04 campus in Myllykoski, Kouvola.

"We are pleased to continue and deepen our collaboration with atNorth. The FIN04 campus in Myllykoski is one of the most significant data center developments in Finland, and it is great to be part of its next phase. As Finland’s leading data center builder, YIT has strong expertise in delivering technically demanding projects and meeting the high quality, safety and security of supply requirements of the industry. We look forward to supporting atNorth in the continued development of the FIN04 campus and its future opportunities in Myllykoski,” said Aleksi Laine, EVP, Infrastructure segment at YIT.
