This design-build contract covers around 7 kilometers of four-lane motorway, and involves the construction of 4 viaducts covering a total of 1.5 kilometer, including the new Grenland cable stayed bridge with a 330 meters main span, excavation of 0.9 kilometer of tunnel, and equipment of 3.3 kilometers of tunnels.
An additional section estimated at €260 million could be awarded to the Eiffage Group in a year’s time after the optimization phase is completed for the construction of a 10 kilometers motorway section, including 5.8 kilometers of twin-tube tunnels.
Based on the Best Value Procurement (BVP), the tender assessment included performance, skill, experience and risk management-related criteria. Eiffage has harnessed the expertise of Eiffage Métal for the construction of Grenland cable-stayed bridge, and several innovations such as Eiffage Route’s GB5® high-performance pavement, the Safety Force® application for on-site risk prevention and Carasol®, a method developed by the Group for swift soil characterisation.
Eiffage collaborated with a number of companies for this tender, including Afry and Greisch design offices as well as the Norwegian firm Bertelsen & Garpestad AS, and has been supported by the bridge expert Mr Michel Virlogeux.
The signature of this iconic contract, which aims to achieve ‘Excellent’-rated Ceequal certification, is set to take place in December 2020. Completion is scheduled for summer 2025.
