Geotechnical failures do happen, either small or large scale, sometimes, even with fatalities. To prevent it to happen, the following steps must be taken:
- Appoint a capable geotechnical engineer (expert) to assess the problem at hand.
- Carry out an adequate, proper and systematical soil investigation as pointed by the geotechnical engineer.
- Analyze, interpret and derived the geotechnical design parameters based on the the available soil data. In a large construction geological and seismicity of the area must also be assessed.
- Asses and understand what type of construction to be built, and also the possible loading imposed to the ground.
- Carry out the short term and long term stability and deformation of the planned geotechnical structure.
- While building the structures (geotechnical structures), install geotechnical field instrumentation (examples: piezometer, inclinometer, pressure cells, etc). Carry out proper and systematical monitoring based on the installed geotechnical instrumentation. Interpret the data properly.
- Re-analyzed the performance of the structure and compare it with the design (prediction) made prior to construction. If necessary make the necessary correction. Admit the error when we, as an engineer, made an error in prediction / calculation and immediately seek a remediation. And if necessary ask for help from a more experience engineer.
- In handling a new type of problem which are complex and difficult, it is better to seek for an advice from fellow capable engineers.
- Be honest to ourselves and never pretend to be clever on everything.
