About this Project

This project involved the installation of four subsurface stormwater detention and slow-release structures at an existing parking facility on PhilaPort’s Pier 98 Annex. AEG initially provided environmental services and later expanded its scope to include survey, construction oversight, and documentation.

AEG sampled and analyzed waste soil stockpiles at the site, conducting environmental soil sampling and chemistry analysis in accordance with PADEP’s 2020 clean-fill policy. The results were compared with Statewide Health Standards to determine contamination levels and appropriate disposal facilities. A summary report was prepared to document findings and recommendations.

AEG’s on-site construction inspector periodically documented and photographed construction activities, comparing field observations with design plans and noting discrepancies. Daily reports included updates on construction progress, as-built changes, and contractor compliance with specifications. AEG ensured the presence of inspectors during milestone events, including City of Philadelphia Special Inspections and critical construction stages.

In addition to environmental consultation and inspection services, AEG performed a Final As-Built Survey to support project closeout.
