Norway state road authority Statens Vegvesen has launched the tender process for a ground investigation and interpretative report for design of a new pontoon bridge for the E39 in Bjørnafjorden.
The new 5km long bridge is part of Staten Vegvesen’s plan to create a ferry free route between Stavanger and Bergen.
The design of the bridge is the result of competition in 2016 that was won by Multiconsult, through collaboration with Aker Solutions, Johs Holt, NGI, Entail and Rambøll, for its “straight, side-anchored pontoon bridge” concept. The design involves a straight bridge floating on pontoons, as well as a cable-stayed bridge at the southern end. Some of the pontoons are side-anchored using cables tied to anchors on the sea bed.
According to documents published in the Official Journal of the European Union, the contract is set to be awarded in mid-September and is expected to take six weeks to complete.
The geophysical survey element of the ground investigation will cover a 5km2 area with acoustic surveys to be carried out at the expected anchor locations.
The deadline for bidding for the GI work is 7 September.
