2024 GRIP Conference
2025 GRIP Meeting
Meeting Information
The 2025 Geotechnical Research in Progress (GRIP) conference will be presented as an in-person session at the FDOT State Materials Office with 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 in-person sites will be limited through the registration process (first come first serve). All others may participate through the Microsoft TEAMS Webinar. PDH credits will only be offered to individuals that attend in person at the in-person sites. To be eligible for the credits, individuals must remain for the entire segment, including any question-and-answer session following the presentations. Certificates will be emailed to the registered email address.
