About this Project
SR 0095-CPR
AEG provided engineering design services for reconstructing and widening SR 0095, Section CPR. This project, with current construction costs of approximately 299 million dollars, completely reconstructed about 1.4 miles of I-95 between Bleigh Avenue and Levick Street, including reconfiguring the Cottman/ Princeton interchange. The work included eight mainline structure replacements or widenings, including the multiple-span State Road Viaduct, new and relocated ramp structures, numerous retaining walls, overhead signs and ITS facilities, relocation of major utilities, geotechnical roadway reports, and both mainline and off-route concrete and Superpave pavement designs and life-cycle analyses. AEG developed and oversaw all geotechnical investigations. Lab testing was principally performed in our certified testing lab. AEG performed or assisted with all foundation designs, including shallow, pile, drilled shaft, and reinforced soil slope alternates and site-specific remediation. AEG developed “no net loading increase” temporary embankments to protect an adjacent 84” diameter water main and 126” diameter sewer culvert. Our staff also redesigned an approximately 700-foot retaining wall to use shallow foundations with a surcharge and settlement monitoring program instead of the previously proposed deep foundations. This resulted in significant constructability and cost savings benefits to the Department. AEG performed pavement design and assisted with developing and implementing one of Pennsylvania’s first high-performance concrete pavement specifications. AEG coordinated and calibrated aerial surveys, completed all the corridor’s supplemental topographic surveys, and developed the digital terrain model used for project design. Our staff assisted in developing Phase II and Phase II Environmental Site Assessments and performed hazardous materials field sampling on behalf of others.
AEG continues to provide construction consultation services for Construction Section CP3.
SR 0095-BSR
AEG provided engineering design services for reconstructing and widening SR 0095, Section BSR. With construction costs of approximately 589 million dollars, this project will completely reconstruct about 1.7 miles of I-95 from Margaret Street to Levick Street, including the Bridge Street interchange. The work included five mainline structure replacements, including the multiple-span Tacony Viaduct, new and relocated ramp structures, numerous retaining walls, overhead signs and ITS facilities, geotechnical roadway reports, and both mainline and off-route concrete and Superpave pavement designs. AEG developed and oversaw some of the most extensive and most complicated geotechnical investigations in known District experience. AEG managed multiple concurrent drilling contracts involving numerous drillers, stringent maintenance and protection of traffic requirements, extensive coordination with utilities and industrial facilities, and nighttime work with staging intermixed with existing long-term construction zones. AEG performed large-scale lab testing in-house and coordinated lab work performed by others to meet the project schedule. AEG performed foundation design, including shallow, pile, and drilled shaft foundations for bridges, walls, and sign structures. Micropiles were used to find structures adjacent to major utility facilities. An integral abutment foundation was developed for the two-span replacement structure carrying Aramingo Avenue over Frankford Creek. Reinforced soil slopes were developed for construction staging.
AEG developed and performed infiltration testing programs to meet current state and local stormwater management and green infrastructure requirements. AEG also developed a subsurface investigation program and subsequent recommendations to obtain Philadelphia Water Department (PWD) approval for installing new and relocated PWD facilities.
AEG continues to provide construction consultation services for Construction Section BS1.
