The development of the former German Marine Base includes new construction that stretches out approximately 1 km / 0.6 mi into the sea. The investor constructed residential and marine leisure facilities with approximately 7,000 beds and 2,000 berths, built in stages. With the residential and leisure facility nearly completely surrounded with waters of the Baltic Sea, its unusual ground conditions (reclamation of land and new construction) as well as a very high ground water table, sandy soil and stage development had to be considered for the infrastructural construction. The accomplishment of the entire facility under these outstanding conditions requires special solutions.
