Tata Projects, one of the fastest-growing and most admired infrastructure companies in India with expertise in executing large and complex urban and industrial infrastructure projects, secured the contract to design and build a part of India's longest sea-bridge – the Mumbai Trans Harbour Link (MTHL). To learn what cutting edge technologies and techniques were used in this project, R SRINIVASAN spoke to Vinayak Pai, Managing Director, Tata Projects. Excerpts:

Please share your Mumbai Trans Harbour Link (MTHL) journey.
MTHL is an iconic project for us. Construction began in March 2018 and the whole sea-bridge was completed in five-and-a-half years. This project was completed at the same speed as some of the big global sea-bridges. Despite going through some remarkable challenges, including monsoon cyclones and two waves of COVID, the project was still completed on time with zero fatalities. MTHL Package 2, which Tata Projects executed along with our partner Daewoo E&C (South Korea), had 0.36 million cu m of concrete, almost 65,000 MT of reinforcement steel and 208 spans of 60 m each, which is formed from 3,100 precast segments and needed almost 6 km of post-tension strands to hold it all together. It is an engineering design and construction marvel and we are proud to have been part of this iconic project, which is the longest sea-bridge in India.
