Session 72 – Review of Geotechnical Reports

INTRODUCTION

SQVE STRUCTURAL SUMMIT

Geotechnical reports are crucial for providing information about subsurface conditions, and inaccuracies or omissions can lead to significant issues during construction and beyond. Some common mistakes or incomplete information that may be found in geotechnical reports include:

  1. Incomplete Site Investigation:
    • Lack of sufficient soil borings or test pits to adequately characterize the subsurface conditions across the entire site.
    • Insufficient sampling depth, leading to limited understanding of the deeper soil layers.
  2. Limited Laboratory Testing:
    • Inadequate or insufficient laboratory testing of soil samples, such as missing essential tests like triaxial tests, consolidation tests, or specific tests for expansive soils.
  3. Incorrect Soil Classification:
    • Errors in soil classification, misidentifying soil types, or overlooking the presence of problematic soils like expansive clays.
  4. Inaccurate Bearing Capacity Estimates:
    • Incorrect estimation of bearing capacity, leading to potentially unsafe foundation design or unnecessary overdesign.
  5. Omission of Groundwater Information:
    • Failure to provide comprehensive information on groundwater conditions, including water table depth, variations, and potential impacts on construction.
  6. Lack of Seismic Data:
    • Incomplete seismic data, overlooking the seismic hazard analysis and recommendations for seismic design parameters.
  7. Incomplete Slope Stability Analysis:
    • Missing or inadequate analysis of slope stability, particularly in areas with significant slopes, which can lead to potential landslides.
  8. Omission of Foundation Design Parameters:
    • Failing to provide clear and detailed foundation design parameters for various foundation types, leading to uncertainty in structural design.
  9. Neglecting Construction Recommendations:
    • Lack of specific construction recommendations, such as proper excavation and backfill procedures, compaction requirements, and site-specific construction considerations.
  10. Overlooking Geotechnical Hazards:
    • Failure to identify and address potential geotechnical hazards, such as subsidence, soil erosion, or groundwater contamination.
  11. Insufficient Settlement Analysis:
    • Incomplete settlement analysis or overlooking the potential for differential settlement, leading to inadequate consideration in structural design.
  12. Missing Future Considerations:
    • Neglecting to address potential changes in site conditions over time or the impact of future developments in the vicinity.
  13. Inadequate Reporting Format:
    • Poorly organized or unclear presentation of information in the report, making it challenging for the structural engineer to extract the necessary data.
  14. Lack of Professional Sign-off:
    • Failure to include the signature and seal of a qualified and licensed geotechnical engineer, raising questions about the report’s credibility.

It’s essential for both geotechnical and structural engineers to maintain open communication and address any discrepancies or uncertainties in the geotechnical report promptly. Regular collaboration and a thorough review process can help identify and rectify potential mistakes before they impact the structural design and construction process.

In the session, Er. Sorabh Gupta will join with us.

REVA VENU V M

I am a budding geotechnical engineering professional. For three years I have worked as faculty in NIT and recently joined as project fellow- geotechnical engineering in a research Institute. Now I am in the transition phase of my career ie, shifting from academics to industry. My desire to become a geotechnical engineering consultant inspired me to join this course. As I don’t have much industrial exposure, attending the course GEO-STR-001 helped me to gain a lot of practical knowledge related to geotechnical engineering. Especially the discussions related to soil investigation, interpretation of soil report and interactive sessions were really amazing. Queries of other participants and the discussions associated with it,were really informative, as it mainly focussed on current industrial practices. Thank you Vivek sir and Bhavin sir for giving this wonderful opportunity. Hoping for a better support in my future endeavours too. Also expecting further courses related to this, in the coming future.

Shefali Thakkar

STEEL-STR-001 was the best interactive course ,wherein all practical facts and limitations those are related with prevailing standards, software and practices were discussed. Vision was provided to participate towards solving such prevailing limitations rather following the same collaboratively. Course content was described very effectively and constant encouragement on experiments of the course deliverables and raising doubts and solving the same. Effective time management by faculty to satisfy all participants’ queries along with effective delivery of course content. 24 hour interaction facility was made available for solving course related queries.

Hiren Desai

The course WIND-STR-002 is very much informative as well as useful for practicing engineers considering the non availability of easy to detailed literatures and practical examples.

STEEL-STR-001 is much awaited course. Finally the industry expert teaching the right thing with right methodology. I had never seen such an excellent online course like this. The amount of knowledge and engagement was extremely good. Thank you so much for the wonderful course.

Kunal Patil

At first I never expected the sessions which are going to be conducted would be so knowledgeable. Day by day listening to Abhay sir touching every aspect from the codal point of view, few from his own experience. The mixture of everything made this course WIND-STR-002 very valuable and useful. Before this course I was trying to learn from everywhere how does this wind dynamic forces are to be calculated but through SQVE consultants arranging this webinar and learning under experience fraternity was worthwhile.

Akshay Thakur

REC-STR-001: The recorded sessions are more than anything for tackling practical difficulties…. and you bring some other professionals like dr. Jain and dr. Gupta is just like awesome experience for the student like me who are from tier-3 college who won’t get such a precious information… thanks to you also for the knowledge you impart… best luck to you and your team for this your initiative to resolve practical difficulties among aspiring structural engineers… 🙏🏻 once again thank you so much… because nobody in today’s era from structural engineering domain is wants to share the information, but you do… kudos!

The course content for STEEL-STR-001 has been thoroughly devised to be effective in best manner. Sharing of Recorded Sessions was the best part as I myself missed few end sessions due to office pressure but I could complete these later on. Making a permanent whatsapp group for discussion was also a good idea.

Parth Gandha

The course STAAD-STR-001 was really amazing an knowledgeable. As I fresher I gained so much knowledge about all the little things I didn’t know that were so much important. Troubleshooting of the software was the most important topic as a single wrong interpretation of the warning can totally change the outcome. I heartily thanks Shri Bhavin bhai and SQVE consultants for introducing such wonderful courses so that we can perform good in practice.

Sharad Gupta

I am very grateful to Er. Dr. Abhay Gupta and Mr. Bhavin Shah for sharing your knowledge with us even though we have the same profession. Your course WIND-STR-002 helped me to clear many of the doubts I had sine the past 20 years.

I Recommend to join STEEL-STR-01 to all upcoming Structural Engineers.

Alok Rathore

After attending the course WIND-STR-001, I change my prospective towards structure and learn many concept.

Dhirender Singh Bisht

I am pursuing masters in structural engineering and steel was the topic that I found always challenging since my B.Tech times. Moreover this is also a missing topic for the syllabus of many universities in masters program. To understand its theory ,and execute it practically in software is really challenging and need a mentor for that. I’ve been following Bhavin sir from last few months and was it was my good decision to choose him as a guide. By the course STEEL-STR-001, now I can feel that I am in a position to explore boundaries of IS code, and also I’m enthusiastic to see how Euro code, AISC code and other countries code tackles the problem which sounds to be complicated in IS code.

Dr. Raksha Parolkar

Topics covered in WIND-STR-002 were new for me to understand, as it has never been covered in syllabus. But the way Dr. Abhay Gupta sir taught, explained the problems and shared his experiences, the subject got easy to understand. I feel proud of being his student.

Kamlesh Mehta

In the course WIND-STR-002, I was not able to attend few lectures due to internet connectivity problem. But I have gone through the video lectures provided by Mr. Bhavin shah and it is positive point that any time any where we can watch and update our knowledge.
