SHN collected and continues to test 2,300 concrete samples as part of the decommissioning of Unit 3 at PG&E's Humboldt Bay Power Plant. The decommissioning requires a way to access the non-operating nuclear reactor caisson for decontamination, demolition, and removal. However, any deep hole along the bay will quickly fill with groundwater unless an underground wall can be constructed that keeps the water out. PG&E contractors (including CB&I, DrillTech Drilling and Shoring, SHN, and many others) recently completed this circular underground wall.
As Vice President of the Redwood Coast Energy Authority’s Board of Directors, Sheri Woo is working to increase public engagement as Humboldt County moves toward establishing a Community Choice Aggregation (CCA) program. A CCA is a program that allows residents to choose the source of their electricity, either from the publicly owned utility or the CCA.
Congratulations to Cody Long and Dawnly Yang, who are now licensed, California Professional Civil Engineers. Licensing exams are rigorous; the 2015 pass rate for the 8-hour “Principles and Practices” test was only 44%. The pass rates for the other two additional exams, in surveying and seismic principles, were 51% and 41%, respectively. Cody and Dawn studied numerous hours on weekends and after work to prepare for and successfully pass these three exams.
Heidi Otten, an environmental resources engineering student studying at Humboldt State University, will be gaining experience and making contacts as SHN’s most recently hired intern, the first of three for Summer 2016. She will be based in the Eureka office, but to understand the numerous facets of civil and environmental engineering, she will be visiting projects based out of our Redding, Willits, and Coos Bay offices.
A career is an individual’s journey of learning and work, and whether SHN is a quick side-trip or a long and rewarding segment depends on the similarities of our future paths. SHN’s path is one that values enhancing our communities and creating a rewarding environment for employees and shareholders. We value team work, life-long learning, and family, health and work balance.
SHN geologists investigated a known fault system to determine potential seismic hazards to the dam. Trenchscan technology was used to record images that were later digitally merged to create a single image of the entire trenched area.
Since 1995, SHN has performed environmental site investigation, hydrology studies, surveys, permitting, remediation design, and infrastructure evaluation and repair designs at 46 sites for CAL FIRE, the California state agency for real estate services (DGS-RESD), and the Division of the State Architect.
Beginning in 2012, SHN’s Biologist of Record managed a crew of 30 biologists that identified nesting locations of birds, prepared and implemented salmonid relocation and dewatering plans, conducted Northern Spotted Owl surveys, and prepared daily and quarterly reports documenting the interactions between construction activities and regulated biological resources.
With Ann Baker Landscape Architecture, SHN assisted in the design of the Museum’s new outdoor nature education facility, incorporating stormwater wetlands and bioretention areas, and encouraging groundwater recharge with infiltration trenches and permeable pavements.
“The Peninsula Light Company and its members will continue to benefit from your efforts long into the future due to the project’s sustainability. On my part, I would like to express my congratulation and gratitude for the professionalism, effort, and persistence you exhibited during the execution of this challenging HDD project. I would be proud to work alongside any of your crew members and staff that brought success to this project.”
