Norja-Lillehammer: Rakennustyöt

The work mainly consists of the renovation of old surface water pipelines (digging up and replacing) on both sides of the E6 between Gran — Kløfta.
Replacement of manholes and pipes, service pipes and drainage system. Renovation of hose cover where this is described. The surface water pipelines on lot IV partly consist of steel pipes that are in bad condition. Lot 5 is mainly concrete pipes.
The removal of concrete constructions that must be driven to an approved waste facility is also included. Necessary securing work with sheet piling and relieving measures are included where the ground conditions require this. The estimated amounts are approximately 2 400 m excavation of ditches, approximately 5 700 m3 of excess matter and approximately 1 000 m pipe renovation with hose.
The work is drawing based with tables. Pipe inspections have been carried out and condition reports have been prepared. Ground surveys are available for the stretch, which were carried out when the motorway was constructed. There may have been some ground levelling by ground owners in some areas.
The stretch from the Gran junction to Kløfta is approximately 7 km.
