Multifunctional Retention Measures in Marburg - Negotiated Procedure for Planning Services for Open Spaces in 2 Lots

The University City of Marburg intends to implement the "Multifunctional Retention Measures" project at two locations (Wehrda and Michelbach) by renaturing a body of water and constructing dams to ensure water-compatible and climate-adapted land use in urban areas. Here: Negotiated procedure for planning services for open spaces in two lots. --- Project Description: Due to its steep topography and large natural surrounding areas, the University City of Marburg is particularly vulnerable to heavy rainfall. As part of the climate adaptation concept, this issue was examined city-wide, and the pilot measure "Retention of Outlying Area Water" was developed with two action modules that have high transfer potential to other areas in the city. The effectiveness of the measures was comprehensively investigated in the climate adaptation concept through numerous 2D flow simulations. With decentralized retention in multifunctional areas, significant areas in the settlements can be protected from heavy rainfall. The two action modules, located on the edge of the city center (Wehrda - Lot 1) and in the rural area (Michelbach - Lot 2), were conceived in conjunction and included in the federal program "Adaptation of Urban and Rural Areas to Climate Change" by the Federal Institute for Research on Building, Urban Affairs and Spatial Development (BBSR) within the Federal Office for Building and Regional Planning (BBR) for funding as the project "Multifunctional Retention Measures." --- Scope of Services: Planning services for open spaces, LPH 1-8 § 39 HOAI plus special services (landscape planning accompanying plan) in two lots (Lot 1 Wehrda, Lot 2 Michelbach). See also Annex Project and Service Description in the tender documents. ---- In parallel, services for structural engineering planning together with structural design services will be tendered in 2 lots (Wehrda and Michelbach) in a separate procedure. ---- Project Costs: Estimated construction costs of €1.06 million net for cost group 500 for Lot 1 and €0.98 million net for cost group 500 for Lot 2 are to be expected. The funding agency has prioritized both lots. Lot 1 (Wehrda) has higher priority than Lot 2 (Michelbach). --- A phased commissioning is planned for each lot. The individual project stages will be successively called off according to project progress. If the client decides to terminate the project after the completion of a project stage, no further call-off will occur. The contractor has no entitlement to call off further project stages.
