Short description
The preparatory work for the Gartnerløkka – Kolsdalen project will include alterations to the infrastructure (pipes and cables) in the ground. The alteration involves, amongst other things, putting district heating pipes, waste water pipes, pressurised water pipes, surface water pipes, and high voltage and fibre cables in a separate route. The route will go in a culvert along Quadrum, otherwise the route will be in a ditch or pressed/tunneled. The pipes will be pressed and laid in a micro-tunnel on two sub-stretches, under the railway and under Gartnerløkka. Sheet piling must be established in order to construct the culvert as well as the press and reception hollows. The work will also include required temporary and permanent alterations to roads, road elements, various equipment, cables, and pipes.
