The Naval Square development consists of urban residential townhouses and multi-story city view condominiums in the Grays Ferry section of Philadelphia. Developed by Toll Brothers, EEI performed geotechnical investigations and full-time construction inspection and testing for all phases of the project. We also conducted stormwater infiltration testing, which included a site specific remediation testing program to amend highly permeable soils to facilitate acceptable infiltration. This testing was performed in cooperation with the City of Philadelphia Water Department. Additional services included shoring (H-pile and lagging), shotcrete soil nail and retaining wall designs, and PA-DEP clean fill testing for transporting excess soils offsite.
