President's Message for 2020-2021

Hello my fellow geotechnical practitioners! I have been looking forward to my presidency, but I expected my initiation to look a bit different. These are challenging and inspiring times given the uncertainty due to the Corona Virus and the civil unrest within our communities; also an incredibly important $1.5 trillion infrastructure bill in Congress could pass and provide future work for our field.  Who knows what will happen in the next year with all these developments?

I do know that CalGeo has supported geotechnical practitioners for 50 years, and we have financial and programmatic foundations that we can rely upon. Our membership is growing, we have a solid financial footing, and our programming increased to meet our members’ demands for excellent technical, legislative, and business/industry content.

We have transitioned seamlessly to online meetings and webinars during this pandemic due to the leadership of our board and Kelly Cabal’s efforts and foresight. We have included new areas on our website for member resources, and we will continue to engage our members and the geotechnical community as we expand our influence in California. Further, we have an industry leading salary survey that David Hamilton recently revamped to provide better and faster data analysis and streamlined presentation capabilities. Collaboration amongst members, with universities, and with our industry partners is at an all-time high, and we need to continue this momentum especially in these challenging times.

For this next year, my goals to help CalGeo continue to meet and exceed your expectations include:

  • Grow our collaborations and sharing amongst our members, affiliates, Emerging Geo-professionals, student chapters, affiliated universities and other geotechnical associations.
  • Establish a 3- to 5-year major project plan coordinated with future presidents to implement over multiple terms.
  • Increase contact and collaboration with other state geotechnical associations to promote technology transfer and to accomplish common goals.
  • Update CalGeo’s strategic plan for the next 5 years.
  • Add additional loss prevention seminars/series geared for project professionals and upcoming company leaders.
  • Develop seminars focused on marketing, training support staff, and accounting.
  • Meet with the student chapter board members throughout the year.
  • Convene and facilitate a symposium for student chapters and Emerging Geoprofessionals to promote sharing operational information, volunteer efforts, and projects that each are working on and to encourage additional collaboration and resource sharing.
  • Add technical series webinars similar to the recent Site-Specific Seismic Ground Motion Hazard Analysis 6-Week Short Course

The history of CalGeo and goals set by past presidents tells me that we don’t shy away from challenges. We will strengthen and expand our programming and services and continue to lead the geotechnical industry.  These goals along with our expanding programming will generate additional CalGeo members and confirm that membership in CalGeo is beneficial and essential to geotechnical engineers.

I look forward to continuing the advancement and growth of CalGeo and the geotechnical profession. Please be safe and take care.

Martin McIlroy
CalGeo President

New Regional Meeting & Webinar: Earthquake Hazards in California, A Practical Approach

Presented by Dr. Alan Hull, Golder

We are working through our Annual Conference speakers bringing their prepared presentations to you via webcast. Dr. Hull was scheduled to present this topic at our Annual Conference this past April that was unfortunately cancelled due to the COVID-19 pandemic.

It is almost 50 years since the California Legislature passed the Alquist-Priolo Earthquake Fault Zoning Act in response to the damage from the 1971 San Fernando earthquake and surface fault rupture. While California’s strict zoning and regulatory responses have not been replicated elsewhere in the world, governments and key industries have developed standards and guidelines to try and mitigate the effects of both strong shaking and surface fault rupture on seismically active faults. In parallel, science has greatly increased our understanding of the earthquake source mechanics, source-to-site path and shallow soil effects, and the ways to capture uncertainties into predictive models.
This presentation will use examples from the western USA and California to illustrate how earthquake and related hazards are incorporated into every-day engineering projects.

Following a brief summary of earthquake fundamentals, illustrated examples will explore how earthquake ground motions are quantified, and then captured into project design criteria, including how uncertainties can be incorporated into probabilistic and deterministic analyses. Examples will show the variety of regulatory approaches used within and beyond California; and explore the needs of engineers and regulators from ongoing scientific inquiry.

About the Speaker:

Dr. Alan Hull is a Senior Practice Leader at Golder Associates in Portland, OR. Alan is a California-registered engineering geologist who focuses on paleoseismology, earthquake hazard assessment and incorporating the effects from seismically active faults into engineering analysis and design. Prior to joining Golder, Irvine CA in 2001, Alan spent 20 years with the New Zealand Geological Survey (now GNS Science) undertaking basic and applied paleoseismic research from fault trenching and marine terrace studies. His consulting assignments for mining, oil and gas, government, and utility clients have been to understand and quantify the hazards from potentially seismogenic faults, probabilistic seismic hazard analyses (PSHA); and the engineering geology at sites in Africa, Asia, Central America, Europe, North and South America; and the South Pacific. Alan has authored more than 50 peer-reviewed journal articles and numerous client-focused reports. Alan was a member of the 2016-2018 Expert Panel supporting the update of California Geological Survey SP 42-- Earthquake Fault Zones: A Guide for Government Agencies, Property Owners/Developers, and Geoscience Practitioners for Assessing Fault Rupture Hazards in California.

Project Award Winner Spotlight

Well, another casualty of COVID-19 is that our amazing project award winners were not allowed to receive their awards in person this April. Instead, we have requested they all submit a short 5-10minute project summary video that will be available on our new On-line Learning Library.

Pro-tip: Access to our On-line Learning Library is through our home-page under the Quick Links menu bar or under the main navigation, Programs>On-line Learning

 WINNER: ENGEO (Public Medium Category)

WETA Central Bay O&M Facility Design/Build Support, Alameda, California

The project was a design-build project with bridging documents including 85 percent plans and geotechnical reports by the Owner’s team. Only three teams bid for the project, which had an Engineer’s Estimate of $46 Million. The Overaa/Power Engineering Construction team had the lowest bid at approximately 20 percent over budget. The team developed several Value Engineering concepts including concepts by ENGEO to bring the project into budget (the savings
were all credited to the owner) so that the project cost could be reduced to within the Owner’s

WINNER: ENGEO (Public Small Category)

City of Roseville City Hall Annex, Roseville, CA

ENGEO prepared a geotechnical exploration report for the 82,000 square-foot, four-story building.
At the time the report was prepared, the structure was going to consist of a steel-moment-frame.
After the geotechnical report was completed, the structural system changed to a precast concrete
structure with precast hybrid moment frames. The increased and much more substantial deadplus-
live loads would have resulted in very large footings that were not practical from a cost
perspective. In addition, eccentric foundation loading from space limitations along the property
line created excessive bearing pressures.

To accommodate the significantly larger structural loads, ENGEO performed supplemental
analysis to evaluate higher allowable bearing pressures. This involved close collaboration with
the structural engineer, Buehler, to accommodate the tolerable structural and architectural total
and differential settlements. Based on the analysis, ENGEO developed site-specific
recommendations to increase the allowable bearing pressures by (1) compacting deeper fills to a
higher relative compaction, (2) deepening the footings, and (3) over-excavating the footings to
gain extra capacity from a deeper, native cemented soil. Where over-excavation of footings was
necessary, the soil was replaced with a lean concrete mix. The over-excavation was also
necessary when thicker undocumented fill was encountered in adjoining areas that could not be
impacted by the project. These techniques resulted in an increase in allowable dead-plus-live
bearing pressures from 3,000 pounds-per-square-foot (psf) to 5,000 psf dead, 7,500 psf deadplus-
live, and 10,000 psf dead-plus-live-plus-seismic/wind.
