Sylvia De Vuyst, surveyor at the Norwegian company Mesta AS.ĭe Vuyst realized immediately after the first site visit that traditional survey tools such as conventional total stations would not work due to several challenges, including low light visibility in a GNSS-restricted environment and the need to measure long linear underground distances with high accuracy.

Sylvia De Vuyst, a professional surveyor at Mesta AS, is responsible for handling the project surveying scope, which includes managing the geodetic control network. Mesta AS, a civil engineering construction company based in Lysaker, Norway, is tasked with managing all the construction crews’ survey needs. The renovation project includes extensive upgrades to each tunnel, including the widening of the carriageways as well as installing new LED lighting, CO/NO 2 gas meters, new water and frost protection and new drainage systems, plus paving new road surfaces. The Kågen Tunnel passes through the Kågen mountain, which is vulnerable to avalanches and landslides. It reaches a depth of 92.5m (303ft) below sea level and some sections of the tunnel have a 10% gradient. The Maursund Tunnel runs under the Maursundet Strait to connect the mainland part of the municipality of Nordreisa with the island of Kågen in Skjervøy. €21 million) project to renovate the Maursund and Kågen Tunnels – two critical underwater road tunnels that connect the city of Nordreisa on the mainland to Skjervøy on Kågen Island.īoth tunnels were built in 1991 and are about 2km long. The Norwegian Ministry of Transport is currently facilitating a NOK 211 million (approx. Mesta AS has opted for a Trimble SX12 scanning total station to benefit from the high accuracy of total station point measurements combined with the speed and precision of 3D scanning. A Norwegian civil engineering construction company is using 3D scanning to survey two critical underwater road tunnels.
