    Abstract:

Applications: 1.SPT N values are very important in the estimation of soil properties for geotechnical design and liquefaction estimation to reduce seismic hazard due to liquefaction induced by the dynamic load. 2.SPT-HEMA can measure energy above split spoon sampler (close to SPT N measurement depth in a borehole) and below hammer (similar to the existing unit). 3.SPT Hammer energy measurements are compulsory and part of SPT Testing requirement in western countries. However, it is not common in Asia and in particular in India, which may be due to cost. 4.SPT HEMA is built by keeping the cost in mind and the Asian market and it has more market potential in Asia than the exiting unit.
Advantages: 1.In India and most of the Asian countries, Hammer energy during SPT test is not measured due to non-availability of low-cost hammer energy instrument. 2.Presently two companies (USA and UK) selling the hammer energy measurement instrument about Rs 12.0 lakh and only able to measure energy above ground level i.e below Anvil in SPT setup. 3.SPT HEMA designed such that it can be used to measure hammer at any depth from below Anvil to above-split spoon sampler. SPT HEMA also has the option to measure energy at two locations if two instrumented rod is used. 4.Right now Ms Syscon instruments come forward to manufacture and sale the same with the unit of Rs 7 lakh for single instrumented rod and Rs 10 lakh for instrumented rods.

THE VISION
THE MISSION
ABOUT I-STEM
It has always been the basic tenet of the Government of India, in generously funding R&D efforts at academic institutions over the years, that facilities established through such support be made available to those needing them and qualified to make use of them for their own research work

However, this was never easy or straightforward for, among other reasons, there was no ready source of information of what facility was available and where. Thanks to the Web, it is much easier today to have a national and regional “inventory of resources”, so as to match users with the resources they need, and to do all this in an efficient and transparent manner.

This can lead to a leap in R&D productivity and greatly enhance the effectiveness of public investment. This is the motivation behind I-STEM.
