What Is a Geotechnical Investigation?

In this video, we're talking with Randy Pail of Driesenga & Associates about geotechnical investigations.
Geotechnical investigations are a vital tool to uncover information about soil and rock's physical and chemical properties. Geotechnical engineers study the load-bearing behavior of soils and rocks. This type of study helps identify the possible causes of engineering problems such as landslides and sinkholes.
Geotechnical investigations identify the foundation and type of soil encountered at a site. They evaluate the soil's load-bearing capacity, landslide potential, slope stability, and flooding susceptibility. Geotechnical investigations are conducted for projects such as civil structures, buildings, roads, foundations, and utilities.

All questions were well and clearly answered. Thank you

[@Retipster]

Thanks for the feedback! Glad you enjoyed it.

[@niukun133]

Thank you so much, I learn so many geotechnical words from your conversation.

[@Retipster]

That's great to hear! Thanks for watching.

[@lindokuhlemtaka7318]

This is very informative

[@Retipster]

Thanks! I'm glad it helped.

[@Tim_Krause]

I've seen those before out on land. Very interesting to know what those machines do!

[@Retipster]

I know! It was a big learning experience for me too.

[@khairulzamilnazim8450]

Great

[@CynMasar]

How do I determine the imposed load that the building can sustain? Assuming I don't have the area/width of the foundation

[@hasnan7]

Generally you can see the design load requirement in different building codes, mainly ACI-318 and ASCE 7. These codes have load requirement for all types of buildings (commercial/ residential etc). Designers use these codes as standards.
