Engineering services for replacement construction of B443 bridges over the Leine

Engineering services for the replacement construction of the Leine bridge and a pedestrian and cycle bridge, which carry the B443 over the Leine between Rethen and Pattensen: object planning for engineering structures (HOAI Part 3, Section 3), structural engineering (HOAI Part 4, Section 1), demolition planning for both bridges, shoring planning for necessary excavation pits, and special services for object planning of engineering structures and structural engineering. The replacement construction must be designed according to DIN EN 1991-2, DIN EN 1991-2-/NA, and military load classes STANAG (MLC 70/70-150), and will be carried out in an adjacent position without full closure of the B443 and without a temporary bridge. Planning is BIM-based (LPH 3, variant study method freely selectable) according to Annexes 4.1-4.8 (AIA, sample BAP, etc.) and considers "Constructive and Static Additional Information" (Annex 5). The measure is located in the FFH area "Leineaue zwischen Hannover und Ruthe" (EU code: 3624-331), the "Obere Leine" landscape protection area (code: LSG H 00021), the "Leineaue zwischen Hannover und Ruthe" nature reserve (code: NSG HA 00239), and a flood plain.
