The $65 million Hilliard Bradley High School project consists of a new 1,800 student, 320,000 SF high school. It has an auditorium, field house, gymnasium, academic wing, courtyard and full service kitchen.
Located on a 120-acre site in the Big Darby Watershed, it has 22 basins to collect run-off water from the building and surrounding asphalt pavement. The new high school boasts football, soccer, lacrosse, softball, baseball, tennis, track, and practice athletic fields. The football stadium seats 5,000 spectators.
Rii provided onsite engineering technician services including concrete, soils, and asphalt testing, as well as environmental storm water pollution prevention planning. Rii was also involved in re-designing the orchestra pit in the auditorium due to a high groundwater table.
This project was filled with unique challenges. Due to EPA requirements, the earthwork contractor had to strip, compact, and place fill-in sections to minimize sediment in storm water runoff. One of the challenges of the project was the unstable soil conditions. Employed soil stabilization techniques ranged from undercutting and placing Tensar geogrid to lime modification to reduce the in-situ soil moisture content.
Construction was completed in 2009 and opened for the 2009-2010 school year.
