Denmark – Architectural, construction, engineering and inspection services – Offentligt udbud af rådgivning til Naturstyrelsens forundersøgelse til genetablering af Kolindsund

Kolindsund is a 2,500 ha enclosed area in the middle of Djursland. The area stretches over a 17 km long valley between Kolind in the west and Grenaa in the east, and the area is divided across Syddjurs and Norddjurs municipalities. The investigation area for the preliminary investigation is approximately 3,600 ha. Kolindsund was originally a Stone Age sea, which later became a closed freshwater lake. Until 1872, Kolindsund was Denmark's largest lake. The tender includes a preliminary investigation into the restoration of Kolindsund. Technical and biological advice and assistance are requested. It has been politically decided that the Danish Nature Agency – with financing from Novo Nordisk Fonden, Nordea-fonden and Den Danske Naturfond – shall prepare a preliminary investigation that examines the possibility of restoring Kolindsund as a coherent natural area. The preliminary investigation shall provide a solid and professionally sound basis for a political decision on a possible re-establishment of Kolindsund and shall illuminate the affected landowners' attitude towards such a project. The preliminary investigation shall be carried out with a focus on high professionalism, interdisciplinary approach and involvement of relevant stakeholders and landowners, so that different perspectives and interests together contribute to qualifying the further work with the future development opportunities for Kolindsund. The investigations shall, among other things, uncover the possibilities for improved biodiversity, reduction of nutrient leaching to Kattegat, reduction of greenhouse gases as well as synergies with climate adaptation in Grenaa and the surrounding area. The task also includes a property-related preliminary investigation.
