Chennai Metro Phase 2 project gets new casting yard

For Chennai Metro Rail’s (CMRL) phase 2 project, a casting yard is being set up at Muttukadu along East Coast Road (ECR). The yard has been set up to cast ring segments for building metro rail tunnels to control driverless trains across Chennai’s important areas.

The ring segments, which are to be cast, will go into tunnels on corridor-4 from Lighthouse to Power House in Kodambakkam and will cover around 10 km. Phase-2 tunnelling is expected to begin before the end of this year whereas the 118.9 km phase-2, including underground sections covering 48km, is expected to be operational by 2025-26 and a part of corridor-4 will open first by June 2025.

Tunnels are being constructed by putting together precast concrete rings. The yard will cast about 9,000 ring segments, which will go into the construction of the 10 km twin tunnels. Two stretches which are Lighthouse to Bharathidasan Road covering 5.15 km and 4.8 km Bharathidasan Road to Power House ramp with 10 stations and carry a four-year deadline.

According to the CMRL officials, tunnel boring machines will start arriving by August whereas the tunnelling is expected to begin in various locations by October end or the start of November. At least 23 tunnel boring machines will be operated across the phase-2 corridors for faster construction.

CMRL will use the ‘earth pressure balance’ method for tunnelling in which the cutters on the cutter head of the TMB rotate and drill through soil supplying force and pressure. It injects foam to soften the earth for drilling and then the machine holds up a few feet of earth in front of its face by applying pressure before moving forward.

Creativity is for Humans, Productivity is for Robots!

On most construction sites, the rhythm of progress is measured by the clang of steel, the hum of machinery and the sweat of thousands. But increasingly, new sounds are entering the mix: the quiet efficiency of algorithms, the hum of drones overhead, and the precision of robotic arms at work. Behind the concrete and cables, an invisible force is taking hold: data. It is turning blueprints into living simulations, managing fleets of machines, and helping engineers make decisions before a single brick is laid. This is not the construction of tomorrow; it is the architecture of today – built on ..
