Geotechnical Philosophy and Cases of Site Reuse

The International Society for Soil Mechanics and Geotechnical Engineering will be presented as the largest geotechnical family with its history with its activities around the world.

The lecture would follow by introducing the philosophy of the SoLGeH principle discussing the importance of data collection, and presenting how the stable engineering solution lies in providing functionality with a cost-effective approach without compromising safety. SoLGeH also includes the subject of matching the units and checking the logic of results.

Engineering is in our daily activities, and observing that is key to our continuing education. The observation of walking on sand for example can tell us a lot about the theory we learned. No relying on intuition to solve an engineering problem as it may lead to wrong conclusions with some examples given.

There are many projects conducted by the author as case histories. Two particular cases stand out and will be presented for their importance in developing sustainable structure and infrastructure because of site reuse.

With the ease of travelling around the globe these days, the readiness of every engineer to be internationally ready is discussed.

The conclusions emanate from the lessons learned with some impact messages for the future.
