Scope Of Work
THE PROJECT
The School District of Philadelphia planned the construction of a new high school. Although the location was desirable, the subsurface conditions were not.
THE CHALLENGE
The subsurface profile included 20 feet of uncontrolled urban fill. The miscellaneous urban fill would not support the new school on shallow spread footings.
THE SOLUTION
Hayward Baker and the design engineer developed a Rapid Impact Compaction (RIC) program to improve the fill to provide an allowable bearing pressure of 4,000 psf.
RIC is a dynamic compaction system for improving shallow loose soils. The RIC program specified the compaction of 400 points across 150,000 square feet of the building site. The RIC system achieved the necessary improvement of the fill to support the design bearing pressure of 4,000 psf within tolerable settlement limits.
The RIC program successfully improved the urban fill for the Audenried High School site.
