Old US 80 Bridge, Maricopa, AZ

Construction management and administration services for the rehabilitation of the Gillespie Dam Bridge along Old US 80. The 85 year old bridge underwent major repairs, including heat straightening of the bent steel truss members due to large farm vehicles and trucks striking them over the years. Six of the ten bridge piers received pressure grouting under the foundations to protect against potential scouring. Several delaminated areas on the bridge deck were repaired.  A significant amount of coordination took place when the bridge was hydraulically jacked to remove the damaged roller bearings and replaced with modern slide bearings. In addition to the repairs, an Interpretive Center Plaza was constructed to provide for enhanced public access and enjoyment of the historic structure and nearby plant and wildlife. Federal funds were used on this project and met their entire compliance criterion, including LCP Tracker and DBE monitoring, labor standards interviews and detailed project filing. Managing and involved in the daily operations by the contractor and provided insight on meeting critical path schedules. Worked closely with both the contractor and client on meeting the aggressive three month substantial completion date.
