10Copenhagen - New Metroline, M5 Transportation System
Metroselskabet I/SKøbenhavn SDeadline: Aug 25This tender presents a substantial opportunity for prospective contractors to bid for the M5 Transportation System South package (TSS), a critical component of the Copenhagen metro system's expansion. This project is of significant strategic importance, as the M5 line is a fully automated driverless metro system that will not only enhance passenger service on existing metro corridors but is also planned to extend connectivity to emerging urban development areas, including Kløverparken, Refshaleøen, and Lynetteholm in the East Harbour. The M5 is to operate as an independent system, ensuring that its construction and subsequent operation do not disrupt the existing M1-M4 metro lines. The current tender, Phase 1, encompasses the southern section of the line, from København H to north of v/Prags Boulevard, with an anticipated operational commencement in 2036. The broader vision includes the northern section with an anticipated operatonal commencement of the last part of the northern section in 2045 (included in the transportation system contract (TSS-contract) as options) and a potential future extension to form a ring line, signifying a long-term commitment to urban mobility. The procurement comprises the following, together constituting a mixed procurement within the meaning of Article 5 (2) of the Utilities Directive: 1) A TRANSPORTATION SYSTEM for M5 south encompassing the subsystems rolling stock (passenger vehicles, service vehicles and rescue trolleys), railway infrastructure (signaling system and other subsystems, excluding permanent way and power supply "on the line"), and a CMC (control and maintenance center). Furthermore, O&M supplies (supplies related to the O&M providers operation and maintenance activities such as maintenance plans and training). “On the line” refers to deliveries outside the CMC (as the Transportation System Contractor (TSC) is itself responsible for power supply and permanent way within the CMC). The integration of the mentioned TS-subsystems and the integration of the scope of supply of the CWC into the Transportation System (including but not limited to permanent way and power supply on the line) is also part of the TSC's responsibilities and forms part of the TSS-contract. Rolling stock, railway Infrastructure and the CMC are further described in M5-2-TSS-SW (Scope of Work) of the tender documents. 2) MAINTENANCE SERVICES following hand over of the Transportation System related to the continued maintenance of the Transportation System (hereinafter Maintenance Services). The TSS-contract covers both the Transportation System and the Maintenance Services. The Maintenance Services are governed by a separate maintenance contract forming an attachment to the TSS-contract (hereinafter Maintenance Contract) The purchase of the Transportation System and the Maintenance Services should therefore be seen as a whole and only one Tenderer will be awarded the contracts. The expected scope and characteristics of the two contracts are described in the tender documents. 3) OPTIONS Three (3) options are included in the TSS-contract: Option 1: The purchase of up to 5 additional passenger vehicles. Option 2: The extension of the transportation system from Prags Boulevard to Refshaleøen. Option 3: The extension of the transportation system from Refshaleøen to Lynetteholm. Metroselskabet’s requirements relating to the Transportation System are set out in the tender documents, including the draft TSS-contract and the Scope of Works document (M5-2-TSS-SW). Requirements may be developed and changed during the competitive dialogue. As regards the Maintenance Contract, no draft contract or draft specifications are included in the tender documents at this stage. This reflects the fact that a central element of the competitive dialogue will be to explore the scope and structure of the Maintenance Contract, including the distribution of maintenance tasks between the TSCand the future operator of the Transportation System (hereinafter the OAMC). As a central element of the dialogue phase, Metroselskabet wishes to explore the advantages and implications of possible distributions of maintenance tasks between the TSC and the OAMC and the technical, commercial and legal terms that will be relevant depending on the maintenance model chosen. The potential models to be discussed and assessed during the dialogue phase are expected to span from a scope of the Maintenance Contract similar to TSSSA models (“Technical Support and Spares Supply Agreements”) to a scope similar to FSA models (“Full Service Agreements”) whereby the Metroselskabet would procure most goods, works and services needed for the maintenance and continued development of the Transportation System from the TSC. However, also models which are “in between” or a model where the scope will change over time may be chosen. Also the options to purchase additional passenger vehicles and options covering the extension of the line (northern section) are subject to dialogue. Both technical and commercial requirements are expected to be discussed including elements related to pricing. For further detailing of items planned to be subject for dialogue, reference is made to the Instructions to Tenderers (M5-0-TSS-ITT).Geophysical surveys for installation engineering of Offshore Substations and Submarine Cable Routes (excluding Landfall)
