Next excavation contract on Posiva's research facility ONKALO awarded to YIT
Posiva Oy and YIT Rakennus Oy have signed a contract on the next excavation project in the underground bedrock research facility ONKALO located in Olkiluoto. The bedrock facilities of ONKALO are utilised in research and testing activities, and later also for purposes related to the construction and use of the final disposal facility for spent nuclear fuel.YIT will start the excavation project in March 2016. This contract covers the excavation of an access tunnel to the area where the final disposal of spent fuel will take place as well as the excavation of a maintenance and parking garage at a depth of about 430-440 metres below ground. The required rock sealing and reinforcement works are also covered by the contract. The project is estimated to take ten months and employ some 30 persons, including subcontractors.
- This is a continuation to the extensive Finnish high-standard cooperation utilised also before in the research, design and construction projects of ONKALO. The contract also includes an option for development work related to the next contract stage as well as an option for the actual extension contract, says Mr. Erkki Palonen, Corporate Adviser, from Posiva.
- The contract type has been developed from the alliance contract model in applicable parts; this type of a contract has never been used anywhere else. The contract type will be further developed after the start of the contract project towards a so-called partnership contract model. The advantages offered by the contract model we are seeking include flexibility, shared objectives and efficient utilisation of innovations, explains Mr. Ari Bergström, who is in charge of YIT's underground construction business.
Posiva is the first nuclear waste management company in the world to have been granted the construction licence for a final disposal repository for spent nuclear fuel.
