TC304 survey questions to support project on “Creation and distribution of a global survey on the state of the art versus state of practice"

International Society for Soil Mechanics and Geotechnical Engineering (ISSMGE)

Global survey on the state of the art versus state of practice in the varied fields of geotechnical and geo-environmental engineering

 

TC304 - Engineering Practice of Risk Assessment and Management

 

 

Principal theme – Reliability- and risk-informed decision making for design, assessment, and management of geotechnical systems over their service life

 

 

‘Hot topics’ in the practice

  1. Value of reliability- and risk-informed decision making in practice
  2. Geotechnical databases and probability models
  3. Practical methods to manage geotechnical risk for real-world problems (semi-probabilistic, reliability-based, risk-informed)

 

 

Questions related to above ‘hot’ topics

  1. Have you adopted a reliability- or risk-informed method for design, assessment, and/or management of a geotechnical project?
    1. If YES, provide some project details and highlight how your method complements the factor of safety approach?
    2. If NO, what are your reservations or concerns?
  2. In relation to bridging state-of-the-art and state-of-practice, which aspect(s) of reliability- or risk-informed decision making deserve the most attention (e.g. role of engineering judgment, selection of characteristic value, statistical interpretation of site data and other geotechnical data, target reliability/risk level, Bayesian observational approach, codification versus site-specific needs)?
  3. What are the top 3 items in your wish list that you feel would facilitate adoption of reliability- or risk-informed decision making in geotechnical practice (e.g. statistical guidelines, databases, softwares, short courses, clearer design standards/codes, case studies, bibliography)

 

 

Follow-on questions

  1. Which topics do you prefer to read about in a State of Practice (SOP) report on reliability- or risk-informed decision making for geotechnical engineering?
  2. What activities should TC304 engage in to bridge state-of-the-art and state-of-practice?
  3. What are the grand challenges in the state-of-the-art that will exercise the greatest societal impact?
