CAPG Session, "Are we over-designing?"Background
The Corporate Associates Presidential Group (CAPG) of ISSMGE initiated a worldwide survey on the state-of-practice and the state-of-the-art in geotechnical engineering. The results of this survey were presented at a workshop at the 19th ICSMGE, Seoul, in 2017, and subsequently published in the ISSMGE Bulletin Volume 12, Issue 2, April 2018, (http://issmge2014.ust.hk/apr2018/2.CAPG_report.pdf), as well as in a number of journals. Following this work, CAPG has organised a series of workshops at the ISSMGE regional conferences being held in 2019. Further information can be found on https://www.issmge.org/corporate-associates/corporate-associates-presidential-group.
At the XVI Danube European Conference (Skopje, June 2018), the question was raised “Are we overdesigning?”. Although the question originated from the Asian Region, it is valid internationally where different countries and users of various testing techniques or design codes tend to follow local practice for geotechnical design. In response, the CAPG, in association with Young Members Presidential Group (YMPG), Technical Committee TC205 (Safety and Serviceability), and Technical Committee TC304 (Risk) has launched a global survey intended to assess the consistency of calculation models and design methods for a variety of geotechnical structures and, where possible, to compare the results with full-scale tests and reliability analyses. Please visit https://www.issmge.org/news/are-we-overdesigning-a-survey-of-international-practice) to participate in this survey. The initial results of the survey will be presented at the 16ARC in Taipei, and a detailed analysis of the results will be presented at the ISSMGE International Conference in Sydney 2021.
The main objectives of the CAPG Session at the 16ARC are to stimulate discussions and communication in the geotechnical fraternity, and to produce some useful outcomes for our industry to share and adopt. We believe that the topic of “Are we over-designing?” touches a very sensitive and real issues both in Asia and in the wider international context. The CAPG has invited eminent persons in the field of geotechnical engineering from various parts of Asia to present their views at this CAPG session and interact very closely with the audience. The audience at the CAPG session will be encouraged through facilitation of an interactive session to exchange views and experiences from the different viewpoints. As a result, we expect to arrive at valuable conclusions and actions for the betterment of geotechnical practice as we move on to a very challenging future of increasingly demanding projects and continuously decreasing budgets.
We have initiated a social media discussion (https://www.linkedin.com/pulse/we-overdesigning-sukumar-pathmanandavel/) . Participation via this LinkedIn article by all is welcomed, and your inputs will be used for creating an engaging and entertaining CAPG session at the 16ARC.
