In Memory of Kristy

Kristy Chapman-Elbon, our friend and co-worker, passed away from her cancer last month. Kristy fought so hard through many rounds and types of treatments. She was brave and loving through it all, and is greatly missed.

Kristy’s family and her old Girl Scout Troop have established a scholarship in honor of her memory. The scholarship will be awarded annually to encourage girls to pursue a career in STEM. Click here for information about how to contribute. 

Please keep Kristy’s husband, Andy, and her two girls, Mia and Emma, in your thoughts and prayers.

 

BCI Featured in High-Speed Rail Newsletter


The California High-Speed Rail (HSR) featured BCI in the latest issue of their Small Business Newsletter. BCI provides geo-environmental consulting and independent assurance testing on several HSR contracts for Construction Packages 1, 2-3, and 4. Read the full story here.





Our Jolly Good Fellow

The American Council of Engineering Companies (ACEC) recently welcomed BCI's CEO Tom Blackburn into its College of Fellows. According to ACEC, their College of Fellows is "a distinguished class of engineers who have been selected by their peers as deserving recognition for exemplary contributions to the profession.” Tom participated in a leadership capacity at ACEC for over 10 years, and served terms on the Board of Directors and as President for both the local Sierra chapter and the statewide California organization. We are very proud of Tom and grateful to ACEC for honoring him!

ON THE CUTTING EDGE…
HILLS FERRY ROAD BRIDGE/SAN JOAQUIN RIVER SEISMIC RETROFIT PROJECT

  
Blackburn Consulting advanced the geotechnical design for seismic retrofit of the Hills Ferry Road Bridge over the San Joaquin River, a Stanislaus County Public Works project. The 647-foot long, 18-span reinforced concrete structure risks potential collapse. Seismic induced lateral spreading impacts both abutment river channel slopes and the river channel bed deposits.

BCI (with T.Y. Lin) evaluated and designed a retrofit strategy using the current Caltrans 2013 Lateral Spreading Design Guidelines. Caltrans considered this retrofit strategy to be cost prohibitive and unnecessary.

BCI attended several meetings and corresponded with Caltrans earthquake engineering and geotechnical staff. This culminated in Caltrans’ new Draft Memo to Designers 20-15 (Soil Liquefaction and Lateral Spreading Analysis for New and Existing Bridges) specific for design of this "pilot” project. The new Draft Memo relies on abutment/deck and pile plastic hinge resisting forces to reduce lateral spread movements to suitable levels for new bridge or retrofit design.

BCI used the new Draft Memo guidelines to develop a graph of required structural resistance vs. lateral spread displacements based on slope stability analysis methods. T.Y. Lin used BCI’s graph to develop a new retrofit strategy recently submitted to Caltrans.
