Scope of the tender

The service of owner and stakeholder communication is being tendered. Core tasks (mandatory details and allocations are to be taken from the specification) include, among others, communication with owners and holders of public interests, documentation of ownership structures, as well as evidence collection and documentation. The handling of owner and stakeholder management was divided into a total of six lots in the original tender "T140008". Due to a replacement measure, the following Lot 1 is to be re-awarded:

Lot 1: Cluster Unterweser (Systems BalWin4 & LanWin1) - km 00+000 to km 37+000

The subject of the tender are the outstanding services for the completion of the project in Lot 1. Some of the services have already been carried out. To ensure project progress, interim services are currently being provided. The scope of this tender therefore includes only the residual services described in the tender documents. Information on the current project status and the interfaces to existing services can be found in the tender documents. This is the award of residual services within an already ongoing project. To ensure project progress and to avoid further delays, the tendering procedure will be carried out with shortened deadlines. Please familiarise yourself in good time with the sections "Deadlines", "Questionnaire - Documents", "Messages" and "Question & Answer".
