YIT and Posiva sign contract for stage two in the excavation of Posiva’s final disposal facility

YIT and Posiva Ltd have signed a contract for the excavation work required for completing the second stage of Posiva’s final disposal facility construction. The value of the excavation contract is approximately EUR 17 million, which will be recorded in the company’s order backlog for the third quarter of the year. Set to begin in late 2019, the contract’s duration is estimated at approximately two and a half years.  

The contract includes the stage two excavation of two central tunnels and five final disposal tunnels for Posiva’s final disposal facility in Olkiluoto, an island located in the Finnish municipality of Eurajoki. The new tunnels will form a key part of the facility’s final disposal area and, due to their exceptionally tight quality requirements, they will be the first of their kind in the world. Building such demanding tunnel structures requires exceptional professional expertise.

“We have started the unique EKA project, which in addition to the extraction of the final disposal facility, implements the encapsulation plant in its entirety, and the systems necessary for starting the final disposal of the facilities already quarried”, says Janne Mokka, CEO of Posiva.

YIT has already successfully completed two excavation contracts for Posiva. 

“During our previous contracts, our cooperation with Posiva was very smooth and we are very pleased to be able to continue this cooperation through such a challenging new contract. YIT has a lot of experience in demanding tunnel construction and for us, this new contract represents an interesting opportunity to leverage the strong competence we have,” says Aleksi Laine, SVP, Rock and Special Engineering at YIT.
