Report
Summary
In 2005, consultants completed a rehabilitation design for a portion of the Val Vista Transmission Main that included pipe sizes ranging from 72 inches to 108 inches in diameter. Construction followed completion of the design; however, the entire 13.3 miles was not constructed at that time. A majority of the Val Vista Transmission Main still requires slip-lining or rehabilitation.
A scoping analysis was completed on the transmission main in 2016, which determined the first four sections require priority slip-lining of approximately 5,070 linear-feet of 90-inch and 96-inch transmission main. Additional sections will be rehabilitated in future construction phases.
Services provided by Stanley Consultants, Inc., include, but are not limited to: participation in final design meetings and review of construction plans and specifications; review of proposed cost models delivered by the City's Construction Manager at Risk Contractor; general project administration, construction inspections, special pipeline inspections; provide resident engineering services during construction and act as the City's representative; and provide daily interaction with contractors to clarify job requirements.
