Chennai Metro Project

TSA Riley is providing specialist advisor services for India’s fifth-longest metro rail system. Chennai Metro is a rapid transit system serving the city of Chennai. Phase 1 of the system, comprising 2 lines spanning 45.1 km, was completed in 2019. Phase 2 will extend the network by 118 km, adding 3 corridors and 128 stations. 

Engaged to deliver 4 of the Phase 2 construction packages in 2021, Larsen and Toubro – India’s largest infrastructure contractor – soon faced severe programme delays. They engaged KPMG to provide a new accelerated delivery strategy to overcome labour resourcing, land access and construction challenges within a complex built environment. KPMG appointed TSA Riley to provide constructability advice by assessing the existing construction approach and finding ways to compress the programme and reduce costs. 

Our team successfully introduced innovative construction methods, improving delivery speed and quality. After a comprehensive assessment, we recommended the adoption of value stream mapping for construction activities. This approach facilitated schedule enhancements in site operations such as elevated box girder bored piling and cantilever crosshead delivery. Additionally, TSA Riley proposed the adoption of innovative pile cut-off techniques and vacuum pumps to enhance quality and streamline bored pile operations.
