HDR Named Lead Designer for Pennsylvania Public-Private Partnership Replacing 558 Bridges

HDR will serve as lead design engineer for the Pennsylvania Department of Transportation's first public-private partnership project, which recently achieved commercial close. HDR is on the Plenary Walsh Keystone Partners team tasked with replacing 558 bridges as part of the Pennsylvania Rapid Bridge Replacement Project.

As lead design engineer for the construction joint venture, HDR's responsibilities include bridge and roadway design services, environmental permitting, right-of-way plan development and construction phase services. In addition to HDR, key team members include the Plenary Group, Walsh Group and Granite Construction Company.

The team will begin construction in summer 2015 and complete all bridge replacements by year-end 2017. The commonwealth will retain ownership of the bridges, but the team will be responsible for maintaining each bridge for 25 years.

According to a PennDOT press release, the average cost for design, construction and maintenance per bridge in the project is $1.6 million. Through PennDOT's standard process, the cost to design, construct and maintain a bridge for 28 years would average more than $2 million. In addition to cost savings, the team’s detailed traffic management plan will minimize impacts to the traveling public.

HDR has a strong Pennsylvania presence with offices throughout the state, and has provided transportation services to the Commonwealth for the past 75 years. HDR's experience with large multi-asset replacement projects includes the Oregon Bridge Delivery Partners joint venture, which provided program management, construction management and engineering oversight services for the Oregon Transportation Investment Act III State Bridge Delivery Program. The $1.3 billion program replaced or repaired approximately 400 bridges on state highways.
