Norway – Underwater exploration services – BV 2025-32 - Recipient examinations of the fjord systems around Bergen – from Bjørnafjorden to Gulen (2026-2030)

The assignment "Recipient surveys of the fjord system around Bergen - from Bjørnafjorden to Gulen (2026 - 2030)" is a collaboration between the Government Manager in Vestland and the municipalities of Alver, Askøy, Bergen, Bjørnafjorden, Osterøy and Øygarden, with Bergen municipality as project manager and contracting authority. New in the period 2026-2030 is that the recipient studies shall be carried out in cooperation with the Government Manager in Vestland. Due to this cooperation, the area of investigation has been expanded somewhat compared to previous surveys and for the same reason there may also be some extra stations that can be included in the monitoring programme during the period. These are listed in the option list in Annex 2 Program. The starting point for the assignment is in previously completed recipient surveys for the municipalities, with special emphasis on the extensive "Byfjord surveys" that Bergen municipality carried out in the periods 1973-74, 1979-84, 1990-94, 2000-04, 2011-2016, 2017-20 and 2022-2024. The area covers several fjord sections, which are joint recipients for 2-3 municipalities. The aim of the procurement is to comply with authority requirements on monitoring of recipients in accordance with the Pollution Regulations § 14.9 and the emission permits in each municipality. Furthermore, the procurement shall state the environment and classify the water sources as well as map what possible influences the sewage water has on the water sources. The monitoring programme shall also be used to look at the environmental condition of the main fjord system as a whole, with a particular focus on oxygen content and the oxygen replacement in the main fjord system. The principles and methods in the water regulations shall be followed by monitoring, unless otherwise stated. Tenderers must take into account the time spent on invoicing everyone who contributes to the splice layer. The Contracting Authority provides an overview of actors, invoicing addresses and amounts. Overview of the areas is shown in Annex 1 Map and station overview for the individual areas is given in Annex 2 Program.
