Norway state road authority Statens Vegvesen has launched the tender process for geotechnical ground surveys for floating foundation Bjørnafjorden Bridge.
The call for bids is the second GI contract to the be issued by Statens Vegvesen in the Official Journal of the European Union.
The first was issued last month ground investigation and interpretative report for the new bridge on the E39 route. The latest call invites tenderers to a competition for the execution, interpretation and reports of the soil conditions in Bjørnafjorden and may also include drilling at planned anchor locations.
The floating design is the result of competition in 2016 that was won by Multiconsult, through collaboration with Aker Solutions, Johs Holt, NGI, Entail and Rambøll.
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.
Bids for the work must be submitted by 15 October and the work is expected to be completed by April 2019.
