About this Project

The Rapid Bridge Replacement Project (RBRP) was an $899 million public-private partnership (P3) effort launched by PennDOT to replace 558 structurally deficient bridges across Pennsylvania within three years. Most of the bridges were small crossings in rural areas, making them suitable for standardized design and faster delivery. The project was one of the largest bridge bundling efforts in the United States, aiming to reduce disruptions for travelers while fixing critical infrastructure needs.

AEG played a vital role in the success of the RBRP, contributing to at least 400 of the 558 bridges in some capacity. Our multidisciplinary services included structural, civil, and geotechnical engineering, as well as surveying, hydrologic and hydraulic (H&H) analysis, and construction testing and inspection.

Key contributions included:

• Geotechnical Engineering: Conducted coordinated design reviews and field inspections for over 60 structures, managed boring preparation and inspection, reviewed 25 WEAP Pile Hammer reports, and carried out laboratory testing at AEG’s AASTHO Accredited and USACE Validated Testing Laboratory.
• Surveying: Completed base mapping and utility coordination for 56 structures, including deed research for properties within 300 feet of each bridge.
• H&H Analysis: Developed and reviewed H&H models for 136 structures and conducted quality control reviews for 116 reports and interdisciplinary studies.
• Structural Engineering: Designed and prepared plans for multiple culverts, conducted shop drawing reviews and plan checks for 301 bridge designs, and performed quality control on structural plans.

Despite the fast-paced nature of the project, which often required review and resubmission of Friday night design packages by Monday morning, AEG consistently met deadlines and delivered high-quality work. Our ability to manage multiple task orders across disciplines was crucial in helping PennDOT achieve its ambitious goals.
