Project Awards

Outstanding Project Awards: 2023-2024

Each year at our Annual Conference, CalGeo puts the spotlight on the best geotechnical projects in the state with our Outstanding Project Awards. A panel of peers selects the year's finest work in a number of categories, providing winners with a powerful new marketing message and everyone with the opportunity to learn from exciting, innovative approaches to challenging situations.

Dates: The project awards are for projects completed and constructed between January 1, 2019, and December 31, 2023 (NOTE: For projects submitted as Academic/Research, publication must have occurred between January 1, 2021, and December 31, 2023). So, to be clear, awards will be given at our Annual Conference in 2024 but they are for projects that have been completed by the end of 2023.


Download the requirements (PDF) below to see the current rules for the OPAs. Online submissions (only submission method) were due at the end of 2023. Submissions are only open to CalGeo members and will open for the 2024-2025 cycle in Fall 2024. A fee of $150 is required for each entry. Firms/individuals may submit multiple entries but will only be awarded a maximum of one award per category. Honorable mention awards are often awarded if multiple submissions prove exceptional.
