Water and Sewage Pipelines Bottle Stream for Residences and Cabins

Establishment of water, wastewater, and surface water pipelines for residences and cabins in Flaskebekkveien, Vardeveien, Øvreveien, Nordveien, Kavringstrandveien, Strandpromenaden, Sjøstrandkroken, and renovation of a water pipeline in Vardebakken: approx. 4,230 m of pipelines on existing roads, including mass excavation for ditches. Ditches are mainly 1.7 m deep, up to 4 m in some sections. Rock blasting and pigging are expected due to hard rock and numerous rock formations. Controlled drilling will be used in difficult areas, particularly in parts of Vardeveien and Flaskebekkveien. Installation will be in shallow ditches, with the water pipeline insulated to limit rock blasting. The surface area of the water pipeline will be approx. 1 m, with depth to the bottom rock trenches approx. 1.7 m. Parts of the Flaskebekkveien section will be drilled. A manhole group at K20 (start and reception pit) has a depth of approx. 5.5 m; blasting must be carried out in several stages. This is the prequalification for the competition.
