About this Project
AEG provided structural, civil, and geotechnical engineering, surveying, H&H, and construction testing and inspection services for the Department’s public-private partnership (P3) Rapid Bridge Replacement Project (RBRP). The goal of the P3 RBRP is to replace 558 deteriorating bridges during a three-year target period. Almost all the bridges involved with this project are more minor crossings in rural areas than more significant highways or river crossings. AEG was involved with many disciplines, including tasks such as design reviews/submissions and construction consultation being performed simultaneously.
AEG’s geotechnical responsibilities included coordinating geotechnical design reviews and field inspections for over 60 structures. Our geotechnical department was also involved with boring preparation and inspection, Pilehammer reviews of 25 WEAP reports, and performing laboratory testing services in our AMRL-Certified Testing Laboratory. Additional services included GIS and CADD support.
AEG aided with the survey and basemapping of 56 structures. Utility coordination was completed by AEG before the field survey, as were deed researches for all properties within a minimum of 300 feet of the bridges.
AEG aided with the H&H development and review of 136 structures. AEG was also tasked with the QC review of 116 H&H reports and interdisciplinary studies of corresponding plans and reports.
Our structural engineering department worked hard for this assignment, taking on the challenge of preparing designs and plans for numerous culverts simultaneously. AEG conducted shop drawing reviews and plan checks for 301 bridge designs. Our team of professional engineers QC’ed structural plans, revising designs as necessary.
AEG touched at least 450 of the 558 bridges in some capacity. Despite the many Friday night package arrivals requiring a Monday morning resubmission, AEG always met every deadline while working on an accelerated schedule.
