Project Info: 

Ashley & Vance Engineering provided civil and structural engineering support for this 130 MGD (Peak Hour Flow) water reclamtion facility.  The facility handles much of the municipal wastewater for the City of Spokane Washington.  The contractor IMCO Construction, a Ferndale Washington company began work on the project in October 2014.  The City of Spokane's lead engineering consultant CH2M Hill reviewed Ashley & Vance Engineering plans and calculations for this complex project.

The photographs show temporary shoring for a new silo digester located at the site of an existing digester partially demolished in 2006.  Due to unstable soil conditions the owners engineer had specified a soil freeze method to stablize the earth supporting the DT Building adjacent to the new silo digester location.  To reduce the soil freeze phase of work, Ashley & Vance Engineering designed a cost effective steel bracing system to support the exiting digester wall and DT building.  This allowed the contractor to accelerate the schedule, saving the owner money.  
Other project design work included interior bolster design for thickened concrete wall installation within the DT building.
