SEWER CAPACITY IMPROVEMENTS

Project Owner: City of Tempe
Project Type: Construction Manager At Risk
Construction Dates: 08/19 to 02/20

This multi-phased (two GMPs) project included construction of new sewer lines to address an over-capacity situation and to provide reserve capacity for future needs. Total quantities included the installation of more than 5,900 LF of sewer line (3,334 LF of 24”, 360 LF of 18”, and 2,246 LF of 12”), 19 manholes, 217 LF of curb and gutter, 300 LF of single curb 770 SF of valley gutter, 300 SF of sidewalk, and 9,553 SY of pave/patch. This project also included bypass operations.

The improvements were divided into three segments: 23rd Street from Priest Drive to Hardy Drive, Hardy Drive from 23rd Street to Broadway Road, and 21st Street from Hardy Drive to Wilson Street. This regional upgrade accommodated the United Dairymen of Arizona facility operations. We coordinated with them and worked at night to ensure that their delivery transport and production operations continued uninterrupted. The depth of the excavation and soil conditions required unique shoring to maintain safety and productivity.
