Project Overview

Dedicated Freight Corridor Corporation of India (DFCCIL) is a Special Purpose Vehicle set up under the administrative control of Ministry of Railways to undertake planning & ramp development, mobilization of financial resources and construction, and maintenance and operation of the Dedicated Freight Corridors.

The plan to construct dedicated freight corridors across the country marks a strategic inflexion point in the history of Indian Railways that has essentially run mixed traffic across its network. Once completed, the dedicated freight corridors will enable Indian Railways to improve its customer orientation and meet market needs more effectively. Creation of rail infrastructure on such a scale - unprecedented in independent India – is also expected to drive the establishment of industrial corridors and logistic parks along its alignment.

The Challenges

Closer to railway stations, Alstom needed to construct toe walls due to limited right-of-way. In addition, RCC was not a viable option since the project was piecemeal work spread over 300 km. The economies of scale were not feasible for RCC. Moreover, site supervision and control could not be established for such piecemeal work due to losses with pilferage of shuttering and reinforcement material. Vandalism during construction was another challenge.

Strata Innovative Solution

While toe wall construction is a common feature at railway sites, Strata Geosystems offered a geocell gravity wall with green fascia using its superior quality product – StrataWeb®. StrataWeb® is available in almost 300 colours but green was chosen along with the vegetation. There were 20 locations across the 300 km.

Strata’s Value addition

  • Improved project control leading to efficient logistics
  • Very timely and quick deliveries
  • Ability to use a vandal proof product in a critical application
  • Cost-effective execution of a large but piecemeal project spread over a large area.
