Metro Rail has changed the way people commute within cities in India. Constructing such a complex transit system in a populated country like India is a herculean task. And we at Heritage Infraspace Pvt. Ltd, as a leading construction company in India, take great pride in the fact that we’ve contributed towards the metro construction in India with our diaphragm wall technology, piling and shoring services.
HIPL has provided intelligent ground engineering solutions for various metro construction in India and have executed them with excellence in collaboration with multiple government departments and some of the top construction company in India.
Working with the best
Heritage Infraspace metro construction include the thriving Krishna Park station at Delhi Metro, the elevated station stretch of Kalamasherry-Muttam-Pulinchodu-Aluva for the Kochi Metro, the Bada Chauraha and Chunni Ganj stations of Kanpur Metro and the launching shaft for Ahmedabad Metro.
HIPL worked with some of the biggest names like Larsen & Toubro on the Kochi and Ahmedabad Metro, Gulermak for the Kanpur Metro and Hindustan Construction Company for the Delhi Metro Project. While construction companies in India were the major project executioners, HIPL were awarded with the crucial task of diaphragm wall construction for deep basement underground metro stations.
The Kochi Metro was the first project awarded to HIPL, where we provided our piling services for the elevated stations, constructing 296 piles. HIPL was invited to work on this project when almost every major construction company in India refused to work on the site, majorly because it was close to the dumping yard, which ended up degrading the soil quality and it required some high level soil management and ground engineering to work on it.
Modern problems require modern solutions
Metros always run amidst the hustle and bustle of the modern cities today, hence the construction of underground stations require innovative engineering solutions with state of the art equipment to execute them perfectly. HIPL uses the top of the line machinery from its fleet for its metro projects, like the Jint SG 35 in Ahmedabad, Casagrande B125 for Delhi Metro and
Casagrande B200 in Kanpur. Another crucial piece of machinery which we use regularly on our sites is the Ultrasonic Drilling Monitor, an intelligent utility device for complex civil engineering and foundation work. We sourced it from Koden in Japan, and use it to maintain the verticality of the construction, where every 10 meters the bore’s verticality is checked with a sensor, and precise measurement, display and recording of perpendicularity of drilled holes and the shapes of cross-sections.
Furthermore, we ensure that the soil health is maintained and not damaged post-construction. And for this, we’ve started using polymer solutions in soil maintenance during construction, instead of the traditional Bentonite fluids. This is our way of going green, step by step.
Why HIPL for diaphragm wall construction for metro stations?
The industry trusts and respects HIPL as one of the top construction company in India, because of the value-added engineering solutions, punctuality in terms of deadlines and maintaining the highest standards of safety for everyone involved in the project and the residents of the adjoining areas of the site.
On every project, a safety manager is appointed to liaison with the clients to fulfill every requirement from the construction safety checklist, to ensure all the documents and permits to commence work for steel cages, lifts, etc are in place. HIPL takes anywhere close to 4 to 6 months to complete its diaphragm wall construction for metros, despite delays or stoppage in work for any reason.
Further, all the machinery used in the metro construction projects of HIPL are within the standard age of 5 years or less. Plus, every machine is well maintained and ready to hit the ground running from Day 1. As a result of this, HIPL was awarded the Safety Award by the government for maintaining all the crucial safety standards in the Ahmedabad Metro and Kanpur Metro projects.
