Construction and building services engineering work for local operators at the final disposal facility

Posiva has signed a contract on the construction of the final disposal facility with the Hartela Länsi-Suomi Oy consortium, Vesi-Vasa Oy, Ilmastointi-Salminen Oy and Sähkö-Rauma Oy.

The contract covers the final disposal facility’s construction and building services engineering work in the technical rooms and tunnels excavated for the ONKALO® facility. The contract is valued at about €40 million, and the work will continue until the end of 2022. The contract signed with the consortium is part of the overall project to construct the underground final disposal facility.

- In addition to the construction and building services engineering work agreed to in this context, the work tasks in ONKALO® will involve excavating final disposal tunnels, installing the requisite systems for initiating final disposal and carrying out other preparations for operating activities, Posiva’s Construction Manager Juha Riihimäki says.

- I’m very pleased that we were able to find competitive, capable and cooperative local operators for the work that will continue in the production phase.”

- We are very happy about our consortium being selected as Posiva’s partner in this project. Hartela has extensive experience in construction at the Olkiluoto facility. As a Finnish family-owned business, we greatly appreciate the continuation of this collaboration, especially since the project is as large and significant as it is for the Rauma and Eurajoki regions. The local employment yield of the contract is roughly 200 person years,” Hartela Länsi-Suomi Oy’s Regional Manager Lauri Piitari says.
