An expansion and replacement of the U-shaped west end of Husky Stadium at the University of Washington incorporated the use of precast prestressed concrete seating units. Cast as "double" risers, the seating elements have a rise of 16", a run of 30", and a typical length of 43'-46'. A total of 14 new tiers of seating were added in the open air student section of the football stadium.

Features Prestressing of the seating units allowed for longer spans and increased the bent spacing of the supporting beams. The use of double risers, instead of single L-shaped units, reduced the number of joints and installation "picks" for the erector. The use of precast stadium units shortened the construction schedule and provided a superior finish to cast-in-place alternatives.
