ASCE OC Geo-Institute

From the Field to the Alley

By Adeleine J. Tran, P.E. | G-I First Director

On November 1st, ASCE Orange County Geo-Institute (G-I) had a great turnout at our technical tour on vibro (aggregate) piers hosted by Hayward Baker and Layton Construction. The tour was SOLD OUT with a mix of professionals and student attendees excited to learn about this ground improvement system. After a technical presentation on the design, we went onsite and observed how the pier is constructed using a bottom-feed vibratory probe that densifies the aggregate and surrounding soil. We even got to see the rig up close and talk to the operator on quality-control tips to look out for to make sure that these piers are installed properly.

ASCE OC G-I Technical Tour attendees.

Following our technical tour, G-I ended the year with our 5th Annual Holiday Bowling Social & Fundraiser at Irvine Lanes on December 5th. Over thirty attendees, mixed of geo-professionals and college students, had a great time networking and enjoying a friendly bowling game with their colleagues, old and new. In the holiday spirit, all net proceeds were donated to support our local universities' G-I Student Chapters for their participation in the national 2020 ASCE G-I GeoChallenge Competition. Many thanks to our event sponsors, Hayward Baker and GMU Geotechnical, Inc., professionals, and students for supporting ASCE OC G-I and our student chapters!

Although we had wrapped up our events for this year, we look forward to presenting more technical tours, seminars, and fun activities for our members in 2020.  Feel free to contact us at and join our emailing list.  We look forward to seeing you in 2020!

Geo-professionals and students having an incredibowl time!
