Government of India has taken initiative to augment infrastructure in the country in an expeditious manner. Accordingly, they have planned major investments in roads, water supply, railways, MRTS systems, tunnels, ports etc. Almost 8% of our Gross Domestic Product (GDP) is utilized for new construction in infrastructure and other fields. While the investment is assured and the projects are coming, the need of the hour is to accelerate the pace of construction. This has induced opportunities for introducing new technologies for fast track construction to reduce the cost and time of construction. In the geotechnical arena, we need to seriously look at newer technologies for faster construction of piles and their applications. In this paper, the utilization of Barrette Piles, Continuous Flight Auger (CFA) piles and Spun Concrete Piles have been discussed. Also, discussed is a special application of bored piles, namely Secant Piles which has gained popularity in recent times because of requirement of very deep excavations in thickly populated urban areas for construction of underground stations for MRTS systems.
