GBR initiative – teaming with DFI Subsurface Characterization Committee
Geotechnical baseline reports are fundamental to all projects, but maybe all don’t see the benefits. If you don’t know what type of soil you are building on, the potential for issues both during and after construction increases. The goal of this initiative is to raise the awareness and encourage the adoption of required geotechnical baseline reports to help promote timely, safer and more fiscally responsible projects by providing a clearer understanding of the soil conditions.

This course covers mix designs, materials, equipment, construction, QA/QC, and field demonstrations used for civil and geotechnical, underground construction, shaft/tunnel, and mining projects. More information is coming soon about the 2024 Shotcrete Short Course in Sealy, TX.
