The Federal Agency for Real Estate Tasks in Germany from Europe region has released this tender for As part of the Federal Government s housing initiative the Federal Agency for Real Estate BImA is planning the redevelopment of one of the former General Customs Directorates in Potsdam The federal property previously used for administrative buildings has been completely cleared and prepared for urban redevelopment The aim is to create approximately 135 new rental apartments through high-quality new construction with a diverse mix of housing types These apartments will be allocated to federal employees at affordable rents as part of the housing assistance program This tender concerns the construction of three elevator systems distributed across three multi-family buildings as a separate project for the selected general contractor Building Site B - Multi-family Building B1 Building Site C - Multi-family Buildings C1a and C2 The contractor is required to construct three fully operational elevator systems that comply with the requirements of DIN EN 81-20 and DIN EN 81-50 The elevator systems must meet at least energy efficiency class A according to ISO 25745 The constructed elevator shafts comply with the requirements of DIN 4102 and are designed for the expected loads All components required for installation must be integrated into the shaft walls The contractor is responsible for ensuring that the fastening components are delivered to the structural engineer in a timely manner so that they can be installed Non-elevator-related equipment is not permitted in the elevator shaft The elevators conform to type 02 according to DIN EN 81-70 and are suitable among other things for a wheelchair user of class A or B with an accompanying person Due to local conditions three elevator systems with a pit depth reduced to 360 mm are required for this construction project This exceptionally shallow pit depth results from the structural constraints of the building and precludes the use of conventional elevator technology The elevator pit is located in an area of high groundwater pressure Further deepening of the elevator shaft pit would require significant additional measures for structural waterproofing in accordance with recognized engineering standards and would involve considerably increased technical economic and construction costs Furthermore it would pose increased risks to the long-term watertightness of the structure For this reason an elevator solution is needed that requires a reduced pit depth without necessitating structural modifications to the foundation or the building s waterproofing After a thorough examination of the elevator systems available on the market it was determined that a standard approved elevator solution which meets the required combination of a reduced pit depth of 360 mm a reduced shaft head of 2610 mm and an elevator speed of 1 Achieving a speed of 0 m s while adhering to applicable safety requirements and relevant standards particularly DIN EN 81-20 and DIN EN 81-50 is only possible for a few companies However awarding the contract directly to a single company is not feasible During discussions with the client a reduced elevator pit depth was agreed upon to minimize dewatering efforts and thus optimize costs The elevators in the individual sections will be awarded separately to allow for the integration of the resulting technical and structural parameters into the overall project specifications general contractor tender with tender notice no. 669135-2026 published on 07 Oct 2026.
