Report
Summary
The purpose of this project is to rehabilitate components of the Deer Valley Water Treatment Plant. The City anticipates the following areas to be in need of rehabilitation: solids handling facility, solids area drain pump station, facility-wide valve and gate actuators, and electrical gear and duct banks for the Raw Water and Chemical electrical buildings.
This amendment is necessary due to the additional scope of work that came from the initial condition assessment during the design phase. The amendment will provide additional funds and time to the agreement.
Wilson Engineers, LLC's additional services include, but are not limited to, obtaining all required permits, providing agency coordination services, conducting construction progress meetings, and providing Construction Administration and Inspection services.

Work scope identified and incorporated into the agreement prior to the end of the term may be agreed to by the parties, and work may extend past the termination of the agreement. No additional changes may be executed after the end of the term.
