    • The fence towards the street may be removed if a suitable future use is proposed, in which case a new suitable enclosure for the year-round pool must be provided.
    • A minimum 5m clearance for maintenance measures and access for maintenance of the outdoor areas or their future use is required.The core scope of work for this tender, an "Ideenwettbewerb" (ideas competition) for the "Umgestaltung Ostufer Salzgittersee" (redesign of the East Bank of Salzgittersee), includes the following deliverables: a Site Plan (1:2500) detailing trees, plantings, green and sealed areas, qualities, paths, buildings, parking, and emergency routes; a Promenade Floor Plan (1:500); a Relevant Floor Plan Excerpt (1:200); Relevant Section(s) at a suitable scale showing terrain; three simple perspective views; Area Calculations (including sealing and intervention area); an Explanation (max 1000 words + pictograms); a Sustainability and Climate Resilience Concept (max 500 words + pictograms); a List of Submitted Documents; and an Author's Declaration.
