Germany – Construction work for water projects – Ersatz der Schleuse Herbrum - Vergabepaket 3: Wasserbau, Spezialtiefbau, Konstruktiver Ingenieurbau, Erdbau

The project goal, in accordance with the approved preliminary investigation and approved HU planning, is the replacement of the operational, left (western) lock chamber of the Herbrum Lock in the Dortmund-Ems Canal (DEK) to ensure the long-term safety and ease of navigation, as well as the performance of the federal waterway. The new lock chamber is to be commissioned before the western lock chamber is decommissioned (remaining service life approx. 15 years) and is to be adapted in terms of its dimensions and performance to current and future requirements. The replacement of the Herbrum Lock will be realized at the site of the old, eastern lock chamber after its demolition. The project will be implemented within the framework of the Partnership Model for Waterways (PmW) as a pilot project in the form of an Integrated Project Execution (IPA). Characteristic of this model are: - early involvement of all key project participants, - joint development of the construction specification in contract phase 1, - cooperative and transparent project management, - joint responsibility for cost, schedule, and quality goals, - alignment of all decisions with the principle "Best for Project". The PmW is modular in design and consists of two contract phases: Contract Phase 0 – Preparation and Award (current phase) Contract Phase 1 – Integrated Planning (also Joint Specification of the Functional Construction Specification, Risk Management and Determination of the Target Price.) Contract Phase 2 – Execution (Realization based on the jointly developed and agreed specification and joint planning.) For the project, a module combination has been chosen that enables integrated planning and execution in the alliance model with a multi-party contract. Due to the technical complexity, the boundary conditions of construction in existing structures, and the high importance for ongoing shipping operations, this processing model is particularly suitable. The operations building of the ABz. Support Point Herbrum will be demolished and rebuilt on the same site. The currently operational control center on the lock island will be decommissioned. A new control center will be integrated into the building of the ABz. Support Point Herbrum. A separate design AU for this purpose is being prepared and approved by the WSA. The commissioning/traffic release of the new lock is planned for Q2 2032. A detailed description of the tender package 3 - Water Construction, Special Foundation Engineering, Structural Engineering, Earthwork will be provided in section 5.1.
