DFI Shotcrete Short Course

Jointly with ADSC-DFI Micropile Committee to define the state-of-practice for hollow bar elem2.75-day course covering shotcrete engineering, mix designs, materials, equipment, ACI Codes and specifications, construction, inspection, QA/QC, and field demonstrations used for civil and geotechnical, underground construction, shaft/tunnel, and mining projectsents and seek acceptance for use in highway projects.

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.

Tunnel Segment Book

Committee members writing book on tunnel segment design and state of practice
