SHN tests 2,300 concrete samples for nuclear plant decommissioning

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.

With new PE licenses comes great responsibility

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 is SHN’s most recently hired intern

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.

Aerial services expands our surveying capabilities

Having received our “FAA 333 Exemption” from the Federal Aviation Administration, we are greatly expanding our surveying and geographic information systems (GIS) services.  The Exemption allows us to fly small unmanned aircraft to obtain aerial imagery, and certifies that we operate the unmanned aerial vehicles safely and with full responsibility and accountability for people’s safety and privacy.
