Concept of Bored Cast-in-Situ (BCIS) piling was introduced in India during early 1950s and since then are used widely. BCIS piles, despite being widely used today, require skilled supervision, and may not offer faster and quality guaranteed solution under certain sub-surface conditions. There is an urgent need to introduce latest piling technology to ensure higher productivity with high quality standards, addressing safety requirements during execution. Such foundation technology is expected to be an economical answer to accelerate country’s growing infrastructural needs. Realizing this technology gap, DFI of India along with DFI (USA) set ahead an ambitious technology initiative for introduction of Continuous Flight Auger (CFA) piles in India. Looking at the piling practices in USA and Europe, it is well accepted that CFA piles would take less time for installation compared to BCIS piles for a certain range of loads and sub-soil conditions; and therefore, would play a pivotal role to address India’s fast track piling requirements during its immediate future. This paper presents details of the plans and actions on the DFI of India’s CFA technology initiative which is expected to provide useful information on the philosophies of design and execution to be adopted, critical areas and considerations that are currently being addressed for its successful implementation. In fact, there are wide possibilities of CFA piles in assisting fast track projects and is expected to set up a positive ambience for gainful acceptance in India, which otherwise, had been viewed sceptically in the past.
