Technical consulting in connection with separate sewerage in Vissenbjerg, Bred and Skalbjerg (Re-tender)

Assens Spildevand A/S (hereinafter "Client") has, in accordance with Assens Municipality's Wastewater Plan 2018-2027, a strategy to centralize wastewater treatment at one larger treatment plant in Assens. In this connection, separate sewerage of approx. 750 properties in the towns of Vissenbjerg, Bred and Skalbjerg ("The Project") is to be carried out. The towns currently face challenges with flooding from both heavy rain and, in some areas, high groundwater levels, and the service level for rainwater on the ground cannot generally be met. In the parts of the towns that are currently combined-sewered, a robust separate sewerage system must be established that can handle both rainwater and wastewater. In addition, it is expected that near-surface groundwater will need to be managed in several areas. A solution for managing near-surface groundwater must be established simultaneously with the establishment of the sewerage system. The purpose of the Project is to establish a robust and future-proof drainage system in Vissenbjerg, Bred and Skalbjerg through: - Separation of combined systems. - Improved rainwater management in accordance with the service level, including the expansion of 2 existing rainwater basins and the establishment of 21 new basins (10 wet, 8 dry, and 3 pipe basins/underground storage). - Management of near-surface groundwater where it is found to be economically viable in designated areas. - Preparation of the wastewater system for later pumping to the Assens Central Treatment Plant. The tendered contract includes technical consulting assistance in connection with the realization of the Project. The consultant's assistance is expected to primarily include the following: - Preparation of disposition proposals. - Preparation of main project and construction tender - Construction management, safety coordination, supervision, and completion. The Client has not divided the tendered contract into sub-contracts, as the Client assesses that such a division would lead to a number of inappropriate technical, legal, and practical interfaces with the resulting risk of increased transaction costs and risk exposure for the Client.
