Tantia Constructions Company was set up in 1964 by the Late G.P. Tantia to strengthen India’s railway infrastructure. It was one of the first Indian companies to be accredited for ISO 9001:2000 from DNV, the Netherlands in 2001.

For decades, eastern India was dismissed as remote and under-invested. This picture is rapidly changing. With fresh investments being made in the development of roads, railways and airports.

The company entered advanced mechanised road construction in compliance with specifications set by the Ministry of Surface Transport in 1990. Since then, TCL has built roadways in iverse terrains – the hills of Mizoram, coastal areas of Kerala, plains of Punjab and the hard plateau of Karnataka – on schedule.

Tantia established its credentials in the field of construction, widening, conversion, maintenance, strengthening and beautification of roadways, road bridges, highways and flyovers. The company's expertise in the maintenance of road infrastructure will translate into complete solutions for the benefit of the client, community and country.

Extensive knowledge of the local terrain and culture, together with prior experience of undertaking projects on a pan-India basis, will result in nationwide road building opportunities.

The one company that is helping to make this a vibrant reality is Tantia Constructions Limited. A core infrastructure company. A pioneer in creating infrastructure in Eastern India. Enjoying a wide and deep footprint across the region.

In 2011 Tantia Constructions has received a project from Eastern Railway, Construction Department, Kolkata and a project from Bharat Heavy Electricals Ltd., Noida

In 2012 Tantia Constructions received a project from South Eastern Railway, Kolkata.
