Objekt- und TragwerksplanungO

The contract is set to begin in Q1/2028. The contract timeline is structured into several construction phases (Bauphasen), from 0 to 9.

Key Milestones/Phases:

• Bauphase 0: Coordination of the construction site and logistics with the construction contractor, coordination with authorities and third parties, and application for the closure of Cassellastraße for BPH2.
• Bauphase 1: Coordination of services including the establishment of BE-Flächen Süd, creation of ramp foundations South and abutments, and substructure South, as well as KME of the main bridge South.
• Bauphase 2: Coordination of services including KME main bridge North, construction of BE-Nord, and BÜB for work in the track area during the construction of the temporary bridge.
• Bauphase 3: Coordination of services including BÜB during the construction of the North abutment and pier of axis 20 of the main bridge substructure North, KME in the central ramp area, foundation construction for the North ramp, and the lower ramp section of the central ramp.
• Bauphase 4: Coordination of services including BÜB for work in the track area during the assembly and dismantling of the falsework. This phase includes lowering the superstructure, constructing drainage, sealing, surfacing, and the structural shell of the main bridge, including the installation of touch protection.
• Bauphase 5: Coordination of services including the construction of the North ramp, the structural shell of the central ramp, and the construction of temporary stair towers, as well as BÜB for work in the track area during the final dismantling of the falsework.
• Bauphase 6: Coordination of services for the construction of the South ramp.
• Bauphase 7: Coordination of services including the dismantling of the BE-Fläche Nord and the temporary stair towers. The closure of Cassellastraße will be lifted.
• Bauphase 8: Coordination of services for the construction of the North and South stair systems.
• Bauphase 9: Coordination of remaining work and dismantling of the BE-Fläche Süd.

The contract end date and total duration are not explicitly stated.

The core scope of work for this tender involves Objektplanung für Ingenieurbauwerke nach HOAI § 43 (Object planning for engineering structures according to HOAI § 43). The Statement of Work primarily covers Leistungsphase 6 (Preparation of Award), Leistungsphase 7 (Assistance in Awarding), and Leistungsphase 8 (Construction Supervision), with partial inclusion of Leistungsphase 9.

Key deliverables and responsibilities include:

• Leistungsphase 6 (Vorbereitung der Vergabe - Preparation of Award):
• Determining quantities based on individual items, including mass balance and assignment according to the bill of quantities and STLK/TLK_Str standards.
• Preparing tender documents, which involves drafting service descriptions with bills of quantities, special contract conditions, and tender plans.
• Coordinating interfaces with service descriptions from other planning participants.
• Cost control through comparison of priced bills of quantities with cost calculations, documenting and justifying deviations, and updating cost progression.
• Compiling complete tender documents, including digital versions for e-procurement.
• Leistungsphase 7 (Mitwirkung bei der Vergabe - Assistance in Awarding):
• Obtaining offers and preparing construction announcements.
• Reviewing and evaluating offers, preparing price comparisons, and developing evaluation proposals.
• Coordinating and compiling services from technically involved parties.
• Conducting bidder discussions, including preparation, documentation, and follow-up.
• Preparing award proposals, documenting the award procedure, and finalizing the award record.

• Assisting in the contract award process, including preparing necessary documents for concluding the procedure.
• Leistungsphase 8 (Bauoberleitung - Construction Supervision):
• Determining costs and comparing them with the contract sum, including documenting reasons for changes.
• Acceptance of construction services, services, and deliveries, in cooperation with local construction supervision and other involved parties, including defect identification and preparation of acceptance records.
• Monitoring the functionality tests of plant components and the overall system.
• Applying for and participating in official acceptances (e.g., with traffic authorities, fire department).
• Handover of the object, including compiling and transferring required documents.
• Listing limitation periods for defect claims.

Additionally, the contractor is required to create the execution planning for engineering structures, as the draft planning has been completed and approved, and must also prepare the TWP according to Leistungsphase 4 and 5.
