A tunnel link with the mainland will simplify daily life for about 600 residents of Hidra who currently depend on the Kvellandstrand-Launes ferry service. This will also benefit industry and the owners of holiday cabins on the island, and improve access for the many tourist who visit it every year.
The undersea tunnel will be 8.5 metres wide, in line with the requirements of the Norwegian Public Roads Administration. The traffic lane in each direction will be 3.25 metres wide. Driving time through the tunnel is estimated at roughly five minutes. In addition to the tunnel, a 300-metre access road will be built to the marina at the mainland end.
Multiconsult has been responsible for drawing up a complete construction plan, including tender documents.
Technical disciplines include risk management, safety, health and the working environment (SHA), the natural environment and visualisation.
The work has been executed as an infrastructural building information modelling (BIM) project. This means that a virtual three-dimensional model has been created with intelligent object properties for all technical disciplines, based on the requirements and guidance in Handbook 138 on the model basis from the Public Roads Administration.
