Located on St. Johns Road between Palomino Road and Ray Road on the Gila River Indian Reservation, the original project scope specified the extension of culvert pipe and construction of MAG detail 501-1 headwalls at six locations identified as critically deteriorated. This included the removal of 500 LF of culvert pipe, installation of 408 LF of 18in, 331 LF of 24in and 548 LF of 30in CMP as well as restoration of asphalt pavement. During preconstruction, Banicki JOC field teams physically inspected each location specified, documenting the condition of pipe and facilities and determined that 100% of the pipe crossings were deteriorated and functionally inoperable. The Division created a site conditions report and subsequently coordinated with the Gila River Indian Community and MCDOT to identify needed work while minimizing costs by combining mobilization and field crew phasing. As a result of this discovery effort, the Division completed 17 roadway crossings with 34 new headwalls on-time and on-budget with minimal impacts to traffic.
