  • Supply, installation, testing and commissioning of all equipment for the interconnection of the BACS system with the local equipment, already installed and in operation, of the stations and the adjacent shafts of the first phase of the extensions, as required.
  • Upgrading of the servers in operation of the central monitoring and control system, to be selected by the Contractor, for the surveillance and control of the tunnel ventilation system, HVAC system and the total of the E/M system of the second and third phases of the extensions from the OCC, in accordance with the Technical Specifications.
  • Transfer of the servers in operation, of the central monitoring and control system, to be selected by the Contractor, as well as of the Uninterruptible Power Supply System (UPS) in a properly configured area inside the OCC to be indicated by AM.
  • Part of the DFD shall consist in the provision of accurate data on the energy consumption requirements for the entire BACS equipment per station for the supply of the system from the UPS system of each station.
  • Design, construction, supply, testing and commissioning of the Fireman Boxes of the stations under construction/tendering.
  • Design, construction, supply, internal wiring, testing and commissioning of the PLC switchboards to control the operation of the foreseen E/M systems in stations, shafts and depots of the second and third phases of the extensions.
  • Supply and installation of the fibre optics of LAN local network in stations, shafts and tunnels.
  • Worksite acceptance tests and commissioning of the BACS systems of the extensions of the second and third phases.
  • Participation in the Testing and Commissioning of the E/M systems of other Contractors, as required.
  • Participation in and support to the Trial Run of the extensions of the second and third phases.
  • Maintenance activities for the entire warrantee period.
  • Provision of spare parts, tools and testing equipment.
