Report
Summary
The Val Vista Transmission Main was constructed 46 years ago and is critical to water service delivery for Phoenix residents. Rehabilitation on sections of the main began in 2004, to prevent deterioration due to corrosion. Construction plans for rehabilitation of the entire pipeline were prepared in 2007. These construction plans require updating to reflect current conditions and specifications.
Scoping analysis and design prepared by Wilson Engineers, LLC, in 2016, under project WS85500444, determined that the remaining 29,000 linear feet of the Val Vista Transmission Main needing rehabilitation should be re-scoped. This was confirmed during a January 2017 re-inspection of the main.
The scope of this contract will include, but is not limited to: updating construction plans and documents to reflect current conditions; performing internal and external agency permit coordination and preparing necessary contract documents needed for construction; conducting advanced outreach to impacted stakeholders; and conducting cost model reviews and participating in value engineering evaluations.
Wilson Engineers, LLC, has the experience, resources, and historical knowledge of the Val Vista Transmission Main necessary to provide engineering design for the steel structural liner required for this rehabilitation project. Approximately half of the design for the next construction phase has been designed by Wilson Engineers, LLC, which will assist in the next design phase of the rehabilitation project.
