Norwegian roads authority Statens Vegvesen (NPRA) has called for tenders to build the first tunnel package on the world-beating 26.7km long Rogfast subsea tunnel project to be submitted by midday on 5 October Norwegian time. The offers are to be opened that afternoon.
The E013 Arsvågen Lot is one of the two smaller underground packages on the giant tunnelling project and involves a total 4km of drill+blast excavation of construction transportation/ventilation tunnels and a twin-tube branch tunnel at the northern end of the undersea crossing (Fig 1).
Procurement for the second smaller E011 Mekjarvik Lot involving a 700m long tunnel is expected soon.
Statens Vegvesen rescheduled procurement for the three large drill+blast contracts on the project to start later this year with prequalification rounds. The three major contract packages are:
All three lots are expected to be awarded by mid-2018 with construction starting on the package also in 2018.
The Rogfast project is part of Norway’s strategic E39 coastal highway and is located near Stavanger. The subsea fixed link will pass up to 390m below sea level in the Bokna Fjord and the twin tunnels will be linked with cross passages every 250m. The project is expected to be completed by 2025-26.
Rogfast joins another major undersea highway link in the Stavanger area and currently in construction. The Ryfast undersea highway involved excavation of 23km of twin tube drill+blast excavation.
