MMRDA advances 250 m on Orange Gate–Marine Drive tunnel

The Mumbai Metropolitan Region Development Authority (MMRDA) has completed 250 m of underground tunnelling for the Orange Gate–Marine Drive Urban Road Tunnel using India’s largest slurry shield tunnel boring machine (TBM) deployed for an urban road project.

The project involves twin tunnels extending over 7 km beneath critical transport corridors, including Central Railway, Western Railway and Metro Line 3. The work requires high-precision engineering to navigate densely developed urban infrastructure.

Once completed, the tunnel is expected to reduce travel time between Orange Gate and Marine Drive to around five minutes. It will provide direct connectivity with the Coastal Road and Atal Setu, improving east–west mobility while helping ease congestion and reduce vehicular emissions across Mumbai.

The project marks a significant step in strengthening Mumbai’s next-generation transport infrastructure.

Nuvoco Forecasts Rs 130 bn FY27 Revenue

Nuvoco Vistas Corp expects FY27 revenue to top Rs 130 billion (bn) as cement volumes gather pace, the company announced. The figure equates to Rs 130 bn after conversion from crore denominated targets and reflects management guidance for the next financial year. The chief executive outlined that prior constraints had limited volume growth but that recovery in demand during June and July had helped performance. The company expects costs to rise by Rs 100 to 120 per tonne (t) in the ongoing second quarter owing to monsoon related kiln maintenance shutdowns, higher fixed costs, and normal inflati..

India Core Infrastructure Output Rises Five Per Cent in June

India's core infrastructure sectors recorded growth of five per cent in June, marking a five-month high and signalling an upward trend in industrial activity. The expansion was propelled by strong performances in cement, electricity and the newly included iron ore, reflecting broader resilience across key inputs to construction and power supply. The readings point to strengthening domestic demand in construction and power generation. Production of cement and electricity each rose nine point eight per cent in the month, while iron ore output, included in the index under the new series, jumped 4..

Telangana Thermal Plants Hold Limited Coal Stock

The government told the Rajya Sabha that coal-fired power plants across India held 42.8 million (mn) tonnes (t) of coal as of July 12, enough for 14 days of generation at an 85 per cent plant load factor (PLF). The reply said coal supplies were being monitored daily through a joint mechanism and that coal rakes were being given priority to support uninterrupted thermal generation during peak demand. Officials indicated that daily data on stock levels and rake movements was reviewed to manage dispatches and avoid generation shortfalls. The Central Electricity Authority daily fuel report for Jul..
