The West Oak Lane Charter School is located at 7109-7173 Stenton Avenue in Philadelphia. The construction, consisting of a 60,500-square-foot addition to the charter school, will nearly triple the size of the existing facility and more than double its enrollment capacity from 700 to 1,500 students. The addition, designed by JKR Partners, LLC of Philadelphia, provides for 31 new classrooms and a gymnasium occupying two floors. A partial basement will house a library, computer lab, conference area, storage, and utilities. Building plans feature a two-story atrium, and dome skylights. The work also includes demolition of an existing 10,800-square-foot building on the lot to accommodate the addition, a new playground, and reconfigured parking and bus lanes. Earth Engineering Incorporated conducted a complete subsurface investigation for the school. The investigation consisted of field test borings and infiltration testing program, laboratory soils testing, and a complete geotechnical engineering analysis and findings report. EEI also performed environmental and construction quality control services for the project.
