Despite Covid-19 safety protocols, work continues on schedule at one of the highest volume precast, prestressed concrete yards in North America: the Dragados-Flatiron Joint Venture (DFJV) Pre-Cast Facility in Hanford, California. Hanford Pre-Cast Facility crews are on a tight schedule to complete the 40-acre major infrastructure project by February 2022. Within a total of four years, the contractors are fabricating nearly 2,400 California Wide Flange (CWF) girders, 90 tub girders and 12,000-plus deck panels. In order to achieve this, DFJV built a batch plant for the production of self-consolidating type mixes, combining a Vince Hagan HT Haganator with a BHS-Sonthofen twin-shaft mixer, the latter assuring short, but very robust cycles to yield high-flow concretes exhibiting 20-in. spreads with zero aggregate segregation.
