Project Summary

Project
The Hyderabad Metro Rail project is an INR 164 billion public-private partnership that will provide 72 kilometers of new rail transport across three corridors. Given the densely populated metropolitan area, L&T Construction will construct an elevated metro rail viaduct over 80 road junctions, together with three train depots, and green spaces around stations for the convenience of Hyderabad’s citizens. The design therefore takes into account challenging geology, existing utilities infrastructure, plus monuments and heritage structures that cannot be disturbed.

Solution
Designers relied on Bentley software for alignment optimization and analysis, including span configuration parameters for elevated rail viaducts and to minimize the need for portals and cantilever piers. Approximately 65% of the identified corridors curved, requiring designs to ensure smooth transit at commercial operation speeds, without compromising safety. Station design was integrated with track geometry and operational requirements, with energy needs for the stations partially met with installation of solar panels on the roof.

Outcome
The first stage of this public-private partnership project is targeted to be operational by July, 2017. It is being executed in a Design-Build-Finance-Operate-and-Transfer (DBFOT) basis, with a concession period of 35 years. When complete, Hyderabad Metro network will be the first in India to run on a Communication Based Train Control system, which incorporates driverless technology to enhance safety and increase the frequency of trains.

Software
MicroStation, Power Rail Track, RM Bridge, and STAAD.Pro were key to the solution playlist compiled by L&T for the design and engineering of this complex project. Power Rail Track ensured a high degree of accuracy for pier coordinates and bearing angles, and was critical to the safe design of the sharply curved corridors. Foundations and pier designs were analyzed with STAAD.Pro to identify standard substructure designs. RM Bridge was incorporated to assist with 4D analysis, providing fast design iterations and construction stage analysis.
Outcome/Facts:
  • The Hyderabad Metro Rail project is an INR 164 billion public-private partnership, providing 72 kilometers rail transport across three corridors.
  • The project is one of the largest modern transportation systems in the world based on a public-private partnership.
