    Community rebuilding

    SHN engineers are assisting residents affected by the 2015 Valley Fire in Lake County, by designing “erosion triage” measures for the burned residential building pads. This work will require quick mobilization and long, wet days in the field, but we are proud to be of assistance to our community.

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.
