December Regional Meeting: Seismic Response of Fine Grained Soils

Join us on December 3rd at 12-1pm for our last Regional Meeting of 2020.

Liquefaction triggering procedures provided results consistent with observations of liquefaction across much of Christchurch, New Zealand during the 2010-2011 Canterbury earthquakes. However, there are cases where liquefaction assessment methods indicate that there should have been severe liquefaction-induced ground failure, yet none was observed.

Getting the Angle on Inclinometers - Short Course

Last chance to register for our Instrumentation short course starting Thursday this week. It will run for just 2 weeks, on Thursdays from 12 noon to 1:00pm Pacific Time.

Schedule & Instructor:

Lead by Geokon's Geotechnical Service Engineer, Rob Clark, this series will focus on "Getting the Angle on Inclinometers."

November 5th, Inclinometers 101: Installation and Monitoring Techniques

This webinar provides a summary of the inclinometer monitoring system and will include a discussion of inclinometer components, suggested methods for installation of the inclinometer casings, and suggested methods for performing manual measurements with inclinometers.  The material is intended to provide a basic overview of the instrument and help guide the user in getting the most value out of a properly selected and installed inclinometer system.  Subsequent webinars will delve deeper into the plotting and evaluation of the data associated with the inclinometer.

November 12th, Inclinometers 201: Data Evaluation & Case Histories

This webinar provides a continued discussion of the use of the inclinometer system.  In the first half of this discussion, inclinometer data evaluation and plotting examples will be shared, along with identifying and dealing with common errors that can develop with the inclinometer systems.  The second half of this webinar will be a presentation of case histories with examples of some good inclinometer experiences and some not so much.


$50/Members. $150/Non-members. Consider joining as an individual member and gain our entire Online Learning Library access for the whole year! Individual membership is only $150 or contact Kelly Cabal about a new company Trial Membership savings.

Support Our Students: GeoWall Teams in Action

CalGeo is proud to support a growing number of student chapters at Universities across the state. Now more than ever, students need organizations and clubs to keep the connection to other students, industry and hands-on learning.

Many members have already donated to CalGeo's student fund during their membership renewal this year. We really appreciate the support! We plan to turn around and direct these funds directly to our student scholarships and supporting the local GeoWall teams.

CalGeo Student Support Plans for 2020-2021:

  • Award $10,000 in scholarships to students continuing their education (undergraduate or graduate) in a geo-profession. The main award criteria is involvement in their CalGeo student chapter!
  • Increase GeoWall team support from $500/team to $1000/team
  • Aid with speakers and online web-events
  • Provide access to our new Online Learning Library to CalGeo student chapter members
  • Highly discounted course registration for student members

DSA Public School Construction Collaborative

CalGeo is excited to announce that Eric Swenson, one of CalGeo's Board of Directors has been accepted to the California DSA Public School Construction Collaborative (PSCC) on behalf of the geotechnical engineering community. Eric is joining on behalf of CalGeo to represent California's geotechnical engineers at the Division of the State Architect (DSA).

Congratulations Eric!

Malcolm Drilling's Biggest Project: San Francisco

Malcolm Drilling just announced their biggest project in company history at the Southeast Treatment Plant (SEP) in San Francisco, CA for the San Francisco Public Utilities Commission.

Built in 1952, the plant treats 80% of the city’s wastewater, but many of the plants aging facilities need to be upgraded to meet modern seismic standards while improving operational reliability and operational flexibility.

Our work will include the installation of over 800 drilled piles, 260.000 SF of temporary shoring wall with internal bracing and hundreds of tie-backs, over 120.000 CY of mass excavation, off-haul of all spoils and the dewatering of 2 major excavations. We have been engaged as one of the Core Trade Partners working for the MHW/Webcor JV as acting CM/GC following several
years of pre-construction services for the owner – the San Francisco Public Utility Commission.

Stay tuned for further upgrades on this MEGA project!

For more information on this project please contact: Robert Small [email protected]

Emerging Professional Events - Open to Everyone

Think you're too old to learn some new tricks? Our Emerging Professional webinars are open to everyone, even the seasoned geotechs out there.

We have a couple exciting presentations lined up to round out the end of the year.

Registration is now open for our Emerging Professional Webinar on November 20th at 12pm:

Practical Approach to Soil Corrosivity Evaluation

Presented by Ed Hernandez, Project X Corrosion Engineering

The presentation will explain what corrosion engineers need to know to develop their corrosion control recommendations for common construction materials used in underground infrastructure to avoid costly future failures. We'll review how to collect soil samples and where to collect soil samples and the significance of various tests.

Registration is complimentary thanks to CalGeo's Affiliate members but only CalGeo members will have access to the recorded session and materials on our awesome Online Learning Library.

We also have a December EP Webinar on Thursday December 10th @ 11am:

Lightweight Cellular Concrete for Geotechnical Applications

Lightweight cellular concrete (LCC) is a mixture of portland cement, water, and air that can act as a lightweight, strong, durable, and inexpensive soil or fill replacement for geotechnical applications.  LCC saves time, money, and natural resources by replacing aggregates with air bubbles in numerous project applications.  This presentation will introduce construction professionals and the design community to LCC and assist them in specifying this product for daily use.

 For more info and a look into Lightweight Cellular Concrete in practice, read on below!

Light-weight Cellular Concrete in Action

The Orange County Transportation Authority (OCTA) in cooperation with The California Department of Transportation (Caltrans) is widening the San Diego Freeway (I-405) between State Route 73 (SR-73) and Interstate 605 (I-605).The project will improve 16 miles of I-405 between the SR-73 freeway in Costa Mesa and I-605 near the L.A. County line.

OC 405 Partners (OHL USA and Astaldi Construction) lead the design-build team.  

CalGeo's newest Affiliate member, Cell Crete is placing Lightweight Cellular Concrete (LCC) on the I-405 widening project.  LCC will reduce settlement and increase strength compared to earth fill.  LCC is also faster, reduces trucking by an order of magnitude, conserves aggregates, and often reduces total cost.  

This placement is at the southeast corner of the intersection of I-405 with Magnolia in Fountain Valley.  Magnolia will be wider with LCC between a new concrete retaining wall and the existing Magnolia embankment approach to the new longer-span bridge.

New Members, Welcome!

We are so pleased to welcome the following new company members and individual members from across the US and Internationally. Click the logos below to visit each company's website.

New Affiliate Members:

Cell Crete has been placing Lightweight Cellular Concrete (LCC) since 1956.  LCC is lighter and stronger than earth fill, reducing settlement and loads.  LCC has been used routinely for underground tank/void abandonments, annular fills, and crush zones to protect utilities at fault crossings.  Recent applications include raising sites on soft ground for sea level rise.  

LCC is also faster, reduces trucking by an order of magnitude, conserves aggregates, and often reduces total cost.
