About this Project

This on-call contract provides the Philadelphia Department of Streets with as-needed engineering services for infrastructure projects throughout the city. AEG is delivering multidisciplinary support across several assignments, including bridge rehabilitation, roadway reconstruction, and streetscape enhancements.

AEG is leading preliminary design efforts for the 30th Street Viaduct Rehabilitation, a complex structure spanning Market Street to Walnut Street in University City and over Lower 30th Street. The rehabilitation scope includes deck and stringer replacement, structural steel repairs to floor beams and columns, as well as significant components for traffic control and public involvement. AEG performed topographic surveys of both levels of the structure, capturing accessible elements of the superstructure and substructure using electronic total stations. A base plan was developed from field-located data, and an abbreviated Phase I Environmental Site Assessment (ESA) was conducted to identify potential contamination sources, including lead-based paint and asbestos-containing materials.

For the Swanson Street Reconstruction, AEG is supporting preliminary design and utility coordination for the resurfacing and reconstruction of Swanson Street between Columbus Boulevard and Oregon Avenue. The project includes green stormwater infrastructure (GSI), traffic signal upgrades, pedestrian bump-outs, and other Vision Zero streetscape features. AEG is verifying survey data and property lines, coordinating with the City on potential railroad abandonment, and preparing for Phase II hazardous waste activities.

AEG also provided survey and inspection services for the Leverington Avenue Bridge, supporting structural evaluations and recommendations for future rehabilitation.
