Tata Bluescope’s Lysaght roofing used for Delhi Metro

Delhi Metro Rail Corporation (DMRC), a company set up by Government of India and the Government of National Capital Territory of Delhi, started its operations in 1998 and the first section was open to the public in the year 2002.Currently, Delhi Metro is the world's 13th largest metro system in terms of length serving Delhi, Gurgaon, Faridabad, Noida, and Ghaziabad in the National Capital Region of India. Delhi Metro is also India's first modern public transportation system, which has revolutionized travel by providing a fast, reliable, safe, and comfortable means of transport. A unique feature of Delhi Metro is its integration with other modes of public transport, enabling the commuters to conveniently interchange from one mode to another.

DMRC wanted the project to be aesthetically planned and well-maintained. At the same time, they wanted to ensure that the project does not endanger public life, nor lead to ecological or environmental degradation. DMRC wanted nothing less than the best for the entire project, which today stands as a benchmark for other cities in India.

DMRC decided to use steel for roofing of the various stations of MRTS project, not only because of the durability of steel but also the lower time required for steel roofing as compared to concrete roofing. Tata BlueScope Steel partnered with top international consultants who guided DMRC on the latest technical know-how on Metro Rails.

Challenges & Solutions

The Station buildings proposed were typically curved buildings (both convex & concave). LYSAGHT® TRIMDEK® 1015 crimp curved sheets and ‘Z’ Type PURLINS were developed for better production capabilities. DMRC was looking for best material quality with sufficient strength to endure maximum stress and strain in case of any eventuality like earthquake. COLORBOND® Steel in colours Surfmist, Pale Eucalypt, Sky Blue and Torres Blue was used for their aesthetically pleasing, high strength and corrosion resistance. Since it was required to supply the material for multiple station buildings at the same time, we ensured proper planning with coordination within the cross functional teams including Engineering, SCM & PPC teams.

Conclusion

Tata BlueScope Steel successfully met the stringent deadlines with timely deliverables of superior quality profiled sheets for 16 DMRC stations in the Noida–Delhi corridor and 12 TRIMDEK® 1015 crimp curved profiled sheets along with Z-type purlins for 12 DMRC stations.

DMRC is the first metro in the world to receive ISO:14001 certification for establishing an environment management system at the construction stage of the Metro Railway System. The entire MRTS project is being executed keeping in mind the environment, health and safety guidelines laid down by DMRC.

DMRC today stands for reliable and safer commuting, time-saving, reduction in atmospheric pollution, reduction in accident rates, reduced fuel consumption, reduced vehicle operating costs, and increase in average speed of road vehicles, all of which has helped in improving the quality of life of the people in Delhi and making the city much more attractive for economic investment and growth.

India, for the first time, witnessed a colourful steel roofing along with unconventional design (concave/convex) in an infrastructure project like the Railway, making it a landmark project.
