Following the core sampling, groundwater inflow tests were performed along the core holes, at the actual depth of the tunnel. 06 Jan, 2020 Kystverket undertook the extra investigations and value analysis over the first half of 2019. Further cost savings were achieved at the portals with shorter quay approaches found to be possible. The tunnel will be larger and longer than a typical underground cavern for hydropower machine hall. NPRA awarded a Nkr183m ($22.1m) contract to NCC Norway in December 2017 for the design and construction of a 2km-long cross-cut or side tunnel for the transportation of construction materials.

The core samples are 50mm in diameter and 1m in length, taken from along a path steered to run under the centre of the tunnel crown. “We have determined where the most variation of rock quality is expected along the alignment," said Andreassen. The cost of the long-planned ship tunnel project in Norway has been significantly reduced thanks to extra site investigation work and other design revisions. Norway’s Public Roads Administration has an ambitious plan to solve the problem by building the Norway to achieve "floating tunnel" project | Geoengineer.org Operations during the construction of Laerdal tunnel was divided into four main phases: drilling, blasting, loading and transport and excavating and landscaping. Following the extra site investigation, and better pinpointing the weak areas, the planned length of the tunnel remains at 1.7km, as does the cross-section at 36m wide x 50m high, Andreassen said. The tunnel reaches a maximum depth of 292m below sea level. The previous site investigation mainly performed limited inclined core drilling close to the portal areas and those did not reach down to the tunnel level, said Andreassen.

An international invitation to bid is being considered for construction of Norway’s longest and largest rail tunnel project to date. The outcome was a revised project cost estimate of just less than NKr2.7 billion (US$295 million in 2019 prices), beating the allowable level in the earlier 2016 prices, but the gap is even greater when the level is price-adjusted to today at almost NKr3 billion (US$328 million in 2019 prices). The Norwegian Public Roads Administration (NPRA), the governmental body responsible for the project, aims to complete construction by 2050. Planned to be built in the same region, the Romsdal tunnel is also awaiting funding approvals as part of a larger, multi-project fixed link fjord crossing.

Can Norway win the global race to build a 'floating tunnel'? Tunnelling will be similar with a crown heading and benches, except at a larger scale with five benches to be excavated in stages (Fig 2). Kystverket plans to award the works as a single design-build contract with the client retaining all geological risk, Andreassen confirmed to TunnelTalk. Permalink. Overall, the rock along the tunnel alignment is better than previously expected, and there is a more favourable rock stress direction, although some more local leakage of water, he added. Why build a floating tunnel? The Norwegian government are embarking on the largest infrastructure project in the country's history. Artist impression of ship at tunnel portal. Further geological investigations and review of plans for the ship tunnel by Kystverket followed a second round of external quality assurance studies, by Atkins and Oslo Economics, following five years of Phase 1 investigations.
