• Kritis Shaft: In progress are hydraulic works for the transportation and installation of machinery for the pumping room.
• NOMARCHIA Station (station & crossover): In progress are lighting works, namely installation of lighting cables at platform level, ventilation works, namely installation of elbows in the air ducts at the platform zone and installation of a fan and air ducts at level -1. Continued are also hydraulic works through the installation of fittings at the outdoor water supply – sewage manholes of EYATH (at street level). At the crossover, fiber optics related works for the Signaling system are being executed as well as controls for the Traction Power Distribution network.
• KALAMARIA Station: Works for the installation of grids on the floor of the LAS compartment, works for the routing of cables inside the grids and the embedment of the steel bases of the general low voltage switchboard are being continued. In progress are also works for the installation of inlets – elbows at the air ducts, at the platform zone (track 1 & 2)/ construction of air duct network at level -1. Finally, in progress are works for the addition of fittings at the outdoor water supply – sewage manholes of EYATH (at street level), fire protection works, namely installation of special items at the tank of the fire-fighting pumping station and radiocommunication works for the installation of cables in the run extending from room 3.4Τ to the platform.
• ARETSOU Station: In progress are works for the installation of lighting fixtures in various areas, works for the installation of feeding cables from the general low voltage switchboard and works for the addition of inlets-elbows at the airducts of the platform. Moreover, in progress are sewage works in the area of the fire-fighting collector, works for the installation of fittings at the outdoor water supply-sewage manholes of EYATH (at street level) as well as works for the installation of fiber optics for the interconnection of networks.
• Pontou Shaft: Earthing works are being continued through the addition of E/M equipment ducts, works for the installation of lighting fixtures and works for the integration of limit switches for the transmission of signal in the event of door opening.
• NEA KRINI Station: Works for the installation of grids adjacent to the tracks, at track level, as well as works for the installation of lighting fixtures and works for the connection of lighting cables at the respective switchboards are being executed. In progress are sewage works in the area of the fire-fighting collector and works for the addition of fittings at the outdoor water supply – sewage manholes of EYATH (at street level) and works for the insulation of pipes and works for the installation of condensate drains. Moreover, works for the installation of grids in several areas of levels -1, -2, as well as works for the embedment of the steel bases of the cabinets and signaling works, i.e. installation of optic fibers for the interconnection of networks and field equipment controls are in progress.
• MIKRA Station: In progress are works for the earthing of grids in the compartment of the RS substation, as well as finetuning works of the infrastructure for powering the tunnel lighting system, cable connection works in the switchboards and works for the embedment of the steel bases at the general low voltage switchboard. In progress are also network construction works (air ducts, fans, sound attenuators, diaphragms) in the areas located at the west slope of the Station (level -1) and in compartments of level -2, the addition of fittings at the outdoor water supply-sewage manholes of EYATH (at street level) and the embedment of special items into the wall of the pumping station tank. Finally, works for the installation of grids in various areas of level -1 and works for the installation of fiber optics for network interconnection are being carried out.
• Tunnel: In addition to the above works, continued are works for the installation of cable trays at the beginning of the K.P. of the project, cabling works for the traction power distribution system and works related to the feeding cables of the power supply switchboards of Kritis Shaft pumping station and works for the installation of lighting cables at the roof of Nomarchia crossover. In progress are also works for the installation of radiocommunication cables along the tunnel, signaling cable connection works and works for the installation of cable for switchboard signals and jet fans.
