Tunnel breakthrough for Infratek

Infratek will be responsible for electrotechnical installations in the new tunnel on the E16 road between Sandvika and Wøyen in Bærum municipality. This is Infratek’s first tunnel contract.

“We won on price, which was the sole criterion, and the value of the contract with the Norwegian Public Roads Administration is NOK 20.59 million,” reports Jarle Pettersen, who is the company’s division manager. Infratek’s Infra Solutions division will be responsible for the work.

“This is a big day for us. We are entering a new market, a market that is in rapid growth. With this contract, we are showing that Infratek is now also competitive in this area. This project gives Infratek a new dimension. We can literally see the light at the end of the tunnel,” Pettersen says.

The contract concerns the supply and performance of electrical installations for the Bjørnegård tunnel and associated barriers in the daylight close to the tunnel portals. The tunnel consists of two bores, with two lanes in each bore. There are also three technical constructions.

The Bjørnegård tunnel is a 2.3 km two-bore tunnel that constitutes part of the new E16 in Sandvika. The traffic will be considerable, and so will the extent of the technical installations. The electrical job includes the supply and installation of 88 km of cabling, three main distribution boards and three UPS systems. (An Uninterruptible Power Supply, or UPS, is a backup system that ensures the vital functions in the tunnel continue to work in the event of main power failure.)

Infratek will also install and connect a total of 1,653 light fittings in the tunnel, along with 48 fans. The deadline for completion of both assignments has been set to 13 December 2019.
