Posiva signs an agreement with Rakennustyöt Ville Kauppi Oy
Part of the ventilation and hoisting equipment buildings of the ONKALO area will be constructed in the next few months. The construction work covers thousands of square metres.
The excavation work for the ventilation and hoisting equipment buildings were completed in late January. On Monday, 8 March, an agreement on the construction of these buildings was signed with Rakennustyöt Ville Kauppi Oy. The contract agreement covers the first construction stages of the ventilation and hoisting equipment buildings. The first stage of the construction work of the ventilation building includes the uncontrolled side of the building. The controlled side will be built during the second stage. The first construction stage of the hoisting equipment building includes the basement floor. The work was started this week. A couple of dozen builders will work on the construction site for the next thirteen months. The contract should be completed by early April 2011. The plan is for the new ventilation building to take over the ventilation of ONKALO as of June 2011. The rescue basket will be transferred to the supply air shaft in connection with the new hoisting equipment building in May 2011.
The construction project is quite extensive: the first stage of the ventilation building consists of 2,863 m2 of space to be constructed, and the building volume is 13,900 m3. When completed, the ventilation building will be 50 metres long and 20 metres tall. The basement floor of the hoisting equipment building consists of 576 m2 and the building volume is 2,000 m3.
The design of the hoisting equipment building’s second construction stage – meaning the first and the second floor – will begin soon. The second stage of the construction work will be started when the first stage is completed, estimated to be in autumn 2011. The current construction project is limited to the basement and the air raid shelter only. According to the plans, the first and second floor of the hoisting equipment building will include a control room, a hoisting equipment machinery room and auxiliary facilities as well as staff social premises. The gate of the ONKALO area will probably be transferred next to the hoisting equipment building once it is fully complete. The plan is to start the second construction stage of the ventilation building in 2015.
