J Kumar Infraprojects Achieves TBM Breakthrough on Delhi Metro Phase-IV Project
The breakthrough is part of the Aerocity–Tughlakabad corridor under Delhi Metro Phase-IV and involves construction of twin tunnels, a crossover box and four underground stations.
The tunnelling work was carried out under challenging geological conditions, including hard rock strata, unexpected boulders, micaceous zones and continuous water ingress. A particularly difficult 300-metre stretch beneath interconnected ponds created high hydrostatic pressure and required constant monitoring and geotechnical intervention.
JKIL said the breakthrough at the diaphragm wall at Mahipalpur was completed safely and without compromising structural integrity, highlighting disciplined engineering execution and coordinated site management throughout the tunnelling operation.
Dr. Nalin Gupta, Managing Director, J. Kumar Infraprojects Ltd. said: "The TBM drive at Mahipalpur tested us in ways that few projects do. The geotechnical conditions were among the most demanding we have worked through, but the team never lost focus. What broke through that D-wall was not just a machine. It was months of precision, persistence, and collective resolve. This is what JKIL is built on."
The Mahipalpur breakthrough adds to JKIL's expanding record of complex underground works under DMRC. The company currently operates seven TBM machines across active project sites and has established itself as one of DMRC's most prominent contractors by order book.
