Summary
Approving a Professional Services Supplemental Agreement with Ardurra Group, Inc. in the amount of $775,252.00 for professional engineering services associated with the Water Treatment Plant Facility Expansion Project construction and post-construction phase services, and authorizing the City Manager to execute the same.
Resilient, robust and operational infrastructure that is designed to grow and to comply with the City’s Water Master Plan is key to the Sustainable Infrastructure pillar of the City’s Strategic Plan. The following Supplemental Agreement allows the City to implement the design of a new Membrane Building, which is a part of the overall plant expansion, that will ensure the City’s investment in drinking water is sound.
This item approves the supplemental design services for a new pre-engineered metal structure to house the new water treatment membranes, chemical cleaning equipment and other treatment support facilities. The Engineer of Record, Ardurra Group will provide the design of this building as Construction Phase engineering services.
The current design of the membrane system for the 30-MGD plant expansion was based upon retrofitting existing building as recommended from a previous feasibility study performed by others. Upon further discussion with operations staff and the contractor, it is recommended that a new membrane building designed and constructed for the plant 30-MGD expansion. The new building design will greatly improve operational plant maintenance, constructability and minimize treatment process interruption during construction. This project will both reduce risk and maintain plant d...
