The assignment is for the establishment of approx. 4,230 m water, waste water and surface water on existing roads. This involves the extraction of masses for the establishment of water and sewage ditches, as it has not already been established in the area. The ditches shall mainly be 1.7 m deep, but at some stretches/points it is deeper, down to 4 m. The rock is hard and there are a lot of mountains in the open air, so blasting and pigging are expected in large parts of the area. Controlled drilling will be used in areas with difficult conditions. Parts of the Vardeveien and Flaskebekkveien routes will be carried out drilling in rock due to challenging terrain conditions. The installation will be carried out as shallow ditches, where the water pipeline is insulated to limit blasting of rock. The surface area of the water pipeline will be approx. 1 m with depth to the bottom rock trenches of approx. 1.7 m. Parts of the stretch for Flaskebekkveien will be carried out with drilling. The manhole group at K20 (start and reception pit) Depth here will be approx. 5.5 m. This blasting must be carried out in several stages. This is the prequalification of the competition. Procedure: neg-w-call. Review the original TED notice for the complete requirement, lots, amendments and attachments.
