Aggregate Processing Facility Demobilization in Progress

One of the most critical temporary on-site construction facilities has begun demobilization. The aggregate processing facility, referred to as the crusher, included a jaw crusher, cone crusher, vertical shaft impact crusher and wash plant that cost about $10 million to setup for use during construction.  

Throughout the four years of construction, crews produced project-specified crushed rock and aggregate materials needed for many key pieces of the main dam, including various zones of the rockfill embankment, the aggregates for the asphalt core, and hydraulic filters and aggregates for structural concrete.    

The facility produced 1.5 million tons of material, which is equivalent to 50,000 street legal delivery trucks. That converts to a rate of about 1,300 trucks per month, and, based on a 25-day working month, the plant provided the equivalent of 52 delivery trucks per day. That breaks down to nearly three trucks an hour driving to the site every hour, every day, for over three years. 

Many pieces of the plant have already been demobilized, and the remaining pieces will be following suit this month.
