i need a good reply to this post comment that was made on my post.

Excellent and complete discussion, Joseph of the consequences or areas affected for the lack of information of the subsoil used for the structure support.

It's glad to read that most of the students are aware of the importance of performing a subsurface exploration for having information of the mechanical properties of the soil. If having a geotechnical report doesn't guarantee the absence of uncertainties, imagine the panorama without having a complete subsoil exploration.
