Mr. Kulkarni presented a brief of the functions of Science and Engineering Research
Board related to funding for research. He enlightened about a scheme called PACE of
DSIR which provides grant to an institute and a soft loan with an interest of 2.5% to the
industry, for research. He has expressed his concern that only 27-30% of the submitted
proposal is being approved under SERB, which necessitates the need of a conference of
this kind.
The dignitaries hoped that the session would cater to the need of the challenges faced by
the industries with their association with the academia. The inaugural session closed at 10.00AM
and was followed by the presentations and discussions among the participants.
Based on the presentations, the points raised by the participants are listed in the following:
The first presentation was by Mr. S. Jain, Reliance Power Ltd., Mumbai on Coal Bed
Methane. He talked about the contemporary issues related to the identification of
contribution from individual Thin Coal Seam in CBM production, to avoid perforating
and hydro-fracturing less potential seams in large number of development wells to
achieve better economics. Further, he expressed his concern on environmental issues
related to hydro-fracturing and water disposal which can be elevated to research level.
Researchers from IIT Bombay (Prof. Singh), IIT Madras (Dr. Arnepalli), and Sigareni
Collieries (Dr. D. N. Sharma), expressed their desire to collaborate with Mr. Jain, for
submitting the proposal on Enhance Coal Bed Methane recovery (ECBM) using carbon

Mr. S. K. Pandey, Vedanta, opined on stability of slopes/location of development of shear
planes to prevent landslides.
Maj. Gen. S. S. Sharma, SASE (DRDO) envisioned geotechnical issues related to
avalanche in Himalayan range. His presentation focused on methods for strengthening
foundation and exploring new technologies for the cold region. The panel recommended
Dr. Maji, Mr. Gharpure and Dr. Vikas Thakur for coming out with the appropriate
solutions for the same. Prof. Singh requested Maj. Sharma to take up a course dealing
with “Cold Region Geomechanics” at IITB as a stepping stone. Maj. Sharma has
suggested the following:
1. Any road alignment being planned anywhere in India should be vetted by a panel of
Geotechnologists and their recommendations should be taken into consideration while
planning.
2. A large number of highway and railway projects are under planning in Himalayan
ranges, which will involve construction of a large number of tunnels, bridges and other
structures. It is suggested that Geotechnologists should be involved at all stages of the
planning and other activities. Any pre-emptive action of this nature may result in saving
of a lot of time and money.

3. The Geotechnologists in association with the specialists in remote sensing and GIS
should develop special softwares to identify the potential land slide zones, mud slide
zones, stretches affected by seasonal torrents, and weak strata which are prone to road
sinking, and take protective measures well in advance. As per his knowledge the DTRL,
a lab of DRDO, has done a lot of work on this and they should be involved in this
activity. Director DTRL Dr MR Bhutiani may be invited to further deliberate on this
activity.
4. The DST should approach all the road building organizations like BRO to earmark 1 %
of their budget for geotech research. This will help in developing advance techniques for
defence against land slide and other natural hazards.5. Geotechnologists should develop working models for estimating geo-weather
interaction of roads and terrain of strategic importance. Collaboration with DTRL will
help. This will have a lot of implications for defence.
Dr. Vikas Thakur articulated the need of cost effective and sustainable solutions for the
contemporary issues related to Geotechnical Engineering through an internationally
recognised National Geo-test site. Prof. Singh mentioned about INNOR, a collaborative
venture between Norway and India for geohazard mitigation.
Dr. M. N. Bagde, CSIR, Nagpur, proposed issues related to health hazards and the
utilization of fly-ash in underground mine backfilling. The panel suggested him to get
expertise from Mr. S. Pal, NIT, Durgapur.
Mr. Md. Aarif, HCC, Mumbai, proposed the need for research on the effect of bentonite
on pile friction in soft to medium stiff clays / loose to medium dense sand. Mr. Rupam
Mahanta, ONGC-IEOT, opined that CPT (Cone Penetration Test) may be used for
continuous probing of the ground for a better quality of soil investigation and assess the
properties of soil more accurately. It may reduce some uncertainty about the pile
capacity, although the uncertainty in this case is thought to be due to the effect of
bentonite. CPT is not generally being used in the onshore projects in India although it is
used regularly for offshore projects of ONGC. The panel suggested him to get associated
with Mr. Rupam Mahanta, ONGC-IEOT, Panvel, and Mr. Ravi Kiran Vaidya for the
same.

techniques. In this regard, Prof. Dutta, IITD, opined the usage of ECPT for identifying
the liquefaction prone area. Prof. Singh suggested Mr. Raj to collaborate with Dr. Das,
IIT KGP, and generate proposals which can be sent to different IIT’s for perusal. Mr.
Neeraj Chaddha adds: “CISPL in collaboration with A p van den Berg, The Netherlands
is providing these equipment and can possibly look at providing services as long as the
project is big enough. We would certainly like to be a part of this and contribute in a
small little way we can”.
Dr. A. G. Pillai discussed about the existing agricultural scenario in Kerala and suggested
utilization of soil amendments using naturally available materials such as coir pith, which
would enhance the soil fertility and hence the agricultural productivity. Utilization of
marine clay (disposal of which from construction sites is a serious concern) in
conjunction with coir pith to improve water retention capacity of uncultivable sandy
stretches and finding the best possible means of irrigation is the need of the hour. Prof.

8/18/2019 Geotechnology Brain Storming Session at IIT Bombay
16/20
Page 15 of 20
1. DST must accommodate funding for new Indigenous equipment development, which
will enable R & D done at laboratory to take it in to field. These equipment may
be available outside India but it's cost and capacity both, does not fit to our
requirements. Till this date we don't have an appropriate mechanical auger to carve
out correct sized under-ream for friction piles. And piles keep on failing for
inappropriate bulb. Ultimately client goes for Raft foundation even for small
structure. So design fails for want of good equipment.
2. Same is true for drilling for investigation OR utilization of Fly Ash.
3. Funding for NABL accredited labs at concessional interest rates through SIDBI or
other banks for instrumentation required for R & D.4. DST can assess labs it's potential, before sanctioning such schemes.
5. DST must look beyond educational institutions for R & D to transfer Research in to
Technology.

Ms. F. Darikandeh, IITB, coined the development of a concept called “Smart soil”
utilizing nanoparticles and bio-particles.
Ms. J. N. V. Prathyusha, IITB, talked about the application of micro-materials for
stabilization of fine grained soil against its shrinkage and cracking. She has also
emphasized on the creation of an engineered soil (enhanced properties) by application of
sustainable materials.
Ms. S. Lekshmi, IITB, discussed about the advanced instrumentation for soil moisture
content determination and development of sustainable agricultural land.
Mr. N. Dhanani, Perfomax Analytical, Mumbai, showcased the advance instrumentation
facilities being marketed by him related to soil characterization.
Dr. S. Kolathayar, ISM, Dhanbad, talked about the utilization of fly ash for civil
engineering purposes, use of natural geosynthetics in pavements, seismic site
characterization and scope for geotechnical engineers in mining areas.
Dr Varun Joshi, GGSIPU, New Delhi emphasized on use of bioengineering and
engineering measures in stabilization of landslides in NE region. This is very effective
technique in NE region as the weather is very conducive for this activity. This technique
is also implemented in some of the landslide in western Himalaya and came out with avery useful geotechique for shallow slides.

Subsequently, the wrap up session started at 4.00 PM. Prof. Kalyanaraman opined that it is
apparent that ‘research gaps’ have not been addressed properly and emphasized that ‘the
originality’, ‘novelty’ and ‘basic mechanisms’ should be given prime importance for
developing research proposals and submitting them to the DST, SERB. He briefed the
audience about the proposed National conference “Civil Engineering Research Scholars’
meet’ under the aegis of DST at Nagpur, for disseminating knowledge, technologies and
professional practices among the research scholars. Mr. Kulkarni, DST, New Delhi, tried to
highlight the importance of internship for bachelors and for inculcating research culture. He
also suggested for a dedicated website for technology transfer on the realm of geotechnical
engineering.Prof. Singh reminded the audiences to form their respective research groups and submit
good proposals to DST, SERB, at the earliest.
Finally, he has expressed his gratitude towards the panel as well as the participants for
participating in day long deliberations and making the session useful and successful.
