Skanska has signed a $60m contract with Norway’s Public Roads Administration to renovate the Ekeberg and Svartdal tunnels on the E6 and E18 motorways in Oslo.
The project consists mainly of electrical work, fire protection and improved cleaning solution for water from the tunnels.
In addition, technical buildings will be built, evacuation routes upgraded, a layer of asphalt will be added and all signage will be replaced.
The work will largely take place at night to minimise the impact on traffic. Â
The work will begin in the summer of 2017 and will be completed before summer 2019.
Skanska has also been awarded a $41m contract by power company SFE Produksjon to build the Ã˜sterbÃ¸ power plant in the southern municipality of HÃ¸yanger.
The project includes a 7.1km tunnel in the mountain, the drilling of shafts, blasting for the power plant and concrete work in the power station.
The area where the power plant will be built has particularly good conditions for hydropower, with a natural water reservoir with high storage capacity. Several workplaces can only be reached by helicopter. Â
SFE Produksjon will work on the project in collaboration with BKK Produksjon.
Ã˜sterbÃ¸ power plant will have an annual output of 165GWh, which could power around 8,000 households. Â
Construction will begin in May 2017 and the project will be completed during 2020.
