The Chennai Metro rapid transit system is the third largest metro system in India and was opened to over seven million Chennai residents in 2015, after partially opening the first phase of the project.
The Chennai Metro provides a high capacity mass transit sustainable solution to improve connectivity and reduce growing traffic problems. The project aims to offer public transport that is properly integrated with other forms of public and private transport, including buses and sub-urban trains in heavily populated areas, in addition to improving city liveability throughout the state of Tamil Nadu.
Engaged in 2019, SMEC is providing design support during construction for the Chennai Metro Phase 2, which aims to improve connectivity and reduce growing traffic problems in India’s sixth most populous city.
The project involves 26.69km of rail track; 23.33km elevated viaduct and 24 elevated stations. It will deliver a 50-75% reduction in journey time compared to road journey.
SMEC’s specialists are contributing our global expertise and significant rail and metro experience to address a number of design challenges, including the use of elevated track and stations to minimise land acquisition and the costs of tunnelling. The metro system is designed to operate at a maximum travelling speed of 80km/hour. The viaduct includes many sharp curves of up to 125m and very complex long span bridges spanning up to 97m, which will be constructed using the cast in situ balanced cantilever construction method.
Precast segmental construction is being utilised to decrease air pollution, noise and debris, minimise disruption to local traffic and reduce construction time.
The project is being delivered to BIM L-300, which enables improvements in design and construction of the complex infrastructure, including being able to quickly identify issues and opportunities to improve design, constructability and safety.
