Lemminkäinen will build a new diversion channel for the Bergeforsen Kraft AB
power plant in Timrå, Sweden. The value of the Lemminkäinen contract is approximately 43 million euros. If necessary, the new waterway of the plant can be used to effectively decrease the water reserve of the power plant, thereby improving fire safety at the plant’s water reservoir.
The contract includes demanding civil and foundation engineering, concrete
construction and rock and tunnel engineering. The work will include quarrying a 60 metre-long tunnel, 450,000 solid cubic metres of open-cut tunnelling, 250,000 solid cubic metres of opencast mining and 15,000m³ of massive reinforced-concrete casts.
The new waterway is located in the middle of a built-up environment. The tunnel will be build under the busy Ådalsbana and the 331 main road, spanning over the worksite, will be re-directed. Works are expected to be completed at the beginning of 2014.
Bergeforsen Kraft AB is owned by the power companies Vattenfall AB and Eon
Vattenkraft Sverige AB. The plant, built in 1955, produces an average of 735
gigawatt hours of power annually. Its distribution network covers the
Hälsingland province in Central Sweden.
Lemminkäinen has operated on the Swedish infrastructure construction market
since the middle of the 1990s. The company is currently working on improving
the stability and fire safety of two Eon Vattenkraft Sverige AB's dams
