The DoT plans one 18 km line, 5 km of which will be underground, to run through the centre of the main Abu Dhabi island, serving the central business district and major attractions. The scope of the metro package will encompass stations and ancillary buildings; civils (utility diversion, road, bridges, viaduct, tunnel and shaft construction); rolling stock; rail systems; and depot facilities. There will be 12 stations, eight above ground and four underground, and the line will be serviced by fully automated, 80m rolling stock. The DoT highlighted that it believed a challenge for bidders would be the requirement for the internal temperature of the rolling stock to be maintained at an air-conditioned temperature of 24 degrees centigrade.
Light Rail Transport (LRT)
The LRT network will comprise two lines covering the north section of Abu Dhabi island with one line running for 15 km with 24 stops and the other for 13 km with 21 stops. Both lines will run down the middle of roads, so the whole of the affected roads will need to be redesigned and constructed to incorporate pavements, traffic lanes, the tram and landscaping. The lines will be segregated from other traffic but will run at the same level as other traffic on the roads. The trams will be driver operated (so line of sight will be important), should be able to accommodate up to a maximum of 300 passengers, have a low floor to facilitate disabled access, have a ratio of seating to total capacity of 25 per cent and be air conditioned to 25 degrees centigrade (plus or minus two degrees). Three maintenance facilities will also form part of the LRT package.
Bus Rapid Transport (BRT)
The BRT network will comprise one closed loop which is 14 km long with 25 stops and will run either in the middle or at the side of roads, partially segregated from other traffic. Stations will be similar to the LRT network, buses will be driver operated (so again line of sight will be important), carry up to 160 passengers and will have the same seating ratio and air conditioning requirements as the LRT trams.
The analysis and conceptual design stage for the Project has now been completed and the DoT expects to complete its preliminary engineering, design and environmental analysis by the end of this year.
