Norway – Consultative engineering and construction services – Preliminary project main water pipeline Rore-Arendal part 3-5

The aim of the preliminary project is to examine and clarify the basis for further detailed engineering design of the main water pipeline route Rore-Arendal on the stretch between Lerestvedt and Frivoll. This includes the sub-projects RA3 to RA5, including a cross connection to the existing water supply network at Rykeneveien (RA3A). In addition the cross connection from RA3A to Stoa shall be maintained. The route to Stoa shall be upgraded mainly in the current route. The preliminary project shall assess different route alternatives and dimension both the main pipeline and the accompanying cross connections, with the aim of identifying the most appropriate development alternatives. The work shall be carried out on a general level and result in two reports as a basis for further detailed engineering design services: A report for RA3, including RA3A and RA3A-Stoa, as well as reviewing frames and systems for a pump station for further five flow of water in the area at Nygårdshaven. A rap port for RA4 and RA5. In addition a trade report shall be prepared as a basis for the preparation of the zoning plan for the chosen routes.
