Constructing an underground metro system in one of the world’s most populous cities demands extraordinary engineering knowledge and utilization of the latest industry trends and technologies.
For Mumbai Metro Line 3 (MML3), AECOM is providing consulting services regards contractor selection and construction supervision that include determination of the alignment and station locations, preliminary design of underground tunnel and stations, design review, and tender document preparation.
The fully underground line is 20 miles (32.50kms) long and has 27 stations. Due to the fast-track approach of MML3, a clearly defined and novel systematic method was taken in the design development and choice of the tunnel boring machine (TBM). Close collaboration with the client, contractor, and TBM manufacturer, along with the iterative design process, contributed to the successful delivery and launch of the 17 TBMs.
Radio is one of the key telecommunication systems for instant online voice and data messaging between the central control room, trains, and O&M personnel. Our team proposed and implemented IP-based Terrestrial Trunked Radio (TETRA) technology, after successfully doing so with the Hyderabad Metro project. TETRA was specifically designed for emergency personnel such as fire, police, and disaster management, thus enabling MML3 staff to communicate within and across this group of first-responders.
AECOM also proposed and implemented Communications-based Train Control (CBTC), an innovative automated signalling system used to pinpoint the exact location of trains, thus improving headways and safety. At the same time, the increase in traffic enabled by the efficiency of CBTC will translate to increased revenue for the client and better services for the public.
MML3 will connect major Central Business Districts of Nariman Point and Bandra-Kurla Complex, Domestic and International Airports with industrial areas of Maharashtra Industrial Development Corporation (MIDC) and SEEPZ. The project will also connect the various areas in the city which are not currently served by suburban railway.
