Murphy Corridor Improvements
PDB [Progressive Design-Build]
|
A Hamilton joint venture and design lead partnered with the City of Bend to modernize and expand the Murphy Road Corridor from Parrell Road to SE 15th Street in Bend, Oregon. This project had an accelerated schedule and included six transportation sub-projects: three new, single-lane roundabouts; a bridge overcrossing; pedestrian and complete street multi-modal improvements; and new water main and storm facilities.
The corridor improvements were constructed amid a busy residential portion of southeast Bend, including a portion actively under development and surrounded by new residential subdivisions. Close to the project’s eastern limit is an active BNSF rail line. The project includes building a 125-foot-long bridge overcrossing spanning the BNSF mainline, side, and lead track. The team successfully negotiated a permanent access easement allowing for the single-span bridge, access, permitting, and approval of the girder erection plan for the bridge over the BNSF mainline. Due to the fast pace of the project, there was no time to stop work and resolve design issues or conflicts. The progressive design-build team was flexible and proactive when coordinating with the Engineer of Record and local utilities to quickly resolve issues on the fly and maintain project construction. Our team potholed existing utilities ahead of design and provided information to engineers to mitigate design conflicts. Our team assisted utility companies with excavation services when their forces were not available. This allowed the main project work to continue on schedule. To successfully mitigate unforeseen issues and their risks, the team analyzed the issues in the field with the city inspector and owner’s representative to develop solutions. The team then presented these solutions to the Engineer of Record for review and comment. Using this method, they were often able to implement a successful resolution in under one hour. The project resulted in safety improvements on newly connected roads for trucks, cars, bikes, and pedestrians and provides a vital link for emergency medical services (EMS) from southern Bend to St. Charles Health System’s Bend campus. The progressive design-build team delivered the project 18 months earlier than the City’s original schedule and $1.3 million (4%) under budget. |
