Meeting Information

2023 Grip Logo

The 2023 Geotechnical Research in Progress (GRIP) conference will be presented as a hybrid format with in-person session at the State Materials Office (SMO) in Gainesville with the researchers and some participants. There will also be several remote sites at the district materials offices to attend in person as a group. The seats at the SMO campus and remote sites will be limited through the registration process (first come first serve). All others may participate through the Microsoft TEAMS Webinar.
