Ive heard that presently, the method is used in the construction of the Cusat and Kalamassery Town stations. And that it'll be used for constructing all the metro stations other than Aluva main station, Jawaharlal Nehru Stadium, Edappally and Pettah stations.
This method is really cool because vehicles up to 4.50 metre height can ply without any restriction outside the barricaded area, even when the construction of station is progressing,
Its quite safe as all shuttering arrangements are hung from these cantilever steel trusses, which are designed to carry weight of reinforcement cage, concrete, labour and equipment used for concreting
Yes the plan is using a single column steel structure from the median that projects up to 12 metres, instead of using wooden ballies and batten as in normal constructions. As part of it, cantilever steel trusses would be suspended from the steel columns on either side of the station piers.
Actually yes! You must know that its the DMRC that is responsible for the Kochi metro. So the DMRC has actually adopted an innovative method for the construction of metro stations in the city so as to pose minimum inconvenience to the public.
