July 2021

Summer is here! We are all looking at a busy season and a return to work and life as we emerge from the pandemic.


If you didn't catch the results from our return to work survey, we've linked it below. See how others are dealing with a return to work & travel from the COVID-19 pandemic.



Emerging Professional Webinars - Summer Series

Surface & Marine Geophysics Webinar

This summer CalGeo is offering a series of free educational webinars. We have a great line-up starting in July with Surface & Marine Geophysics and Design Elements of Ground Improvement for Liquefaction.


Registration is now open and is free! Click the links below for more information and to register. We will have more webinars coming up in August and September so stay tuned...


July 16th: Surface & Marine Geophysics, presented by ConeTec


July 29th: Design Elements of Ground Improvement for Liquefaction, presented by Jim Gingery, Keller N.A.

Design Elements of Ground Improvement for Liquefaction

Who's Ready to Hit the Greens?


We are excitedly planning our first foray into in-person events for the fall. Time to warm up your swing and register for our NorCal tournament on Friday October 8th @ Poppy Hills Golf Course, Pebble Beach (Monterey). 


We have secured a block of rooms at both the Carmel Mission Inn and the Hyatt Regency Monterey if you wish to stay the night or even for the weekend. We are planning a post-golf reception and awards happy hour. Any spouses or members not golfing are of course, welcome to join the party!


Sponsorships available and not limited to Affiliate members. Get your company name out there and help support CalGeo's students. Click the link for more information below to view available sponsorships.


SUPPORT THE STUDENTS: This is a fundraiser for CalGeo's student chapters and scholarships. Consider bringing your clients, friends, golf-buddies and co-workers. Everyone is welcome regardless of your membership with CalGeo. Let's make this the biggest golf tournament  yet!

SoCal Golf Tournament - Torrey Pines South Course!


Hot on the heels of the NorCal tournament, you can hit up the famous links at Torrey Pines the following week.


Same deal, different course: CalGeo has 40-spots reserved at Torrey Pines' South Course on Thursday October 14th followed by our awards and happy hour reception.


Don't forget to invite your friends, clients, co-workers - anyone! The goal of this is to get back together in a fun, outdoor environment and enjoy a great day of golf. Think outside of just CalGeo members and invite anyone!


Sponsorship & registration is open. We have a small block of rooms at the Hilton Torrey Pines, right on the course so book those before they go!

Project Award Winner Spotlight: Advanced Geosolutions wins the new Geo-Contractor category for the Alameda Landing Waterfront Development

Alamdea Landing Waterfront Development, Alamdea, CA

Design and construction of ground improvement to mitigate geohazards for the Alameda Landing Waterfront real estate development. The ground improvement work comprised over one million linear feet of Wick Drains to expedite a surcharge program to mitigate the compressibility of the soft bay mud, Rapid Impact Compaction of 750,000 square feet of undocumented fill soils, and 43,000 cubic yards of DSM buttress wall to limit the lateral spreading risk to tolerable displacement goals during a seismic event.


Geotechnical Risks:

  • Liquefaction and lateral spreading
  • Compressible Bay Mud
  • Undocumented Fill

Ground Conditions:

  • Undocumented granular fill soils
  • Compressible clay soils
  • Liquefiable natural soil deposits
  • Frequent subsurface obstructions

Site Investigation and Testing: AGI and Langan each conducted drilling and cone penetration test in various areas of the site.  AGI performed additional plate dilatometer testing along the shoreline area to support the selection of engineering parameters used in the constitutive models of our fininte element analyses.  Additional compressive and tensile load testing of the existing wharf piles to evaluate the load capacity and expected performance for the proposed site development. Pile Integrity Testing was also conducted to assess the condition of the existing piles. The capacity and integrity of the existing piles was considered in the design of the project for both vertical and lateral stabilization of the proposed development.


DSM Buttress Design and Evaluation:

  • Site specific Soil-Foundation-Structure-Interaction (SFSI) Analyses to evaluate DSM Buttress wall performance.
  • PLAXIS 2D finite element model (FEM) calibrated by subjecting wharf structure to ground motion observed during the 1989 Loma Prieta Earthquake, and comparing deformation to existing conditions.
  • FEM tested against earthquake time histories from nearby stations scaled to match the target Maximum Considered Earthquake level ground motions for a 2,475-year seismic event.
  • FEM subjected to earthquake scenarios from the Hayward and San Andreas faults.

DSM Buttress Performance:

  • DSM panels work with the existing wharf structure to act as a shear key buttress.
  • RIC densifies the near surface fills and reduces ground level deformation during a seismic event, working to optimize the DSM Buttress ground improvement system.
  • Differential lateral and vertical movement of the proposed future building footprints within 150 feet of the wharf edge reduced to within tolerable limits by the DSM buttress.
  • Earthquake movement reduced by more then 65% across the site.
