QBOLTON & MENK Real People. Real Solutions. July 3, 2024 D.J. Goman Public Works Superintendent 2750 Kelley Parkway Orono, MN 55356 RE: Navarre WTP — Electrical Replacement City of Orono, MN Dear Mr. Goman, 12224 Nicollet Avenue Burnsville, MN 55337-1649 Ph: (9521 890-0509 Fax: (952) 890-8065 Bolton-Menk.com Bolton & Menk is pleased to submit the following scope and fee letter to complete a technical memorandum for electrical replacement work at the Navarre WTP. As you know, Bolton & Menk has the experience and qualifications to provide this service to you. Our scope and fee letter outlines the tasks necessary to complete this technical memo. Project Understanding The electrical switchgear (MCCs) and supervisory control system (SCP) are at or nearing the end of their useful life and require replacement. These systems are critical systems for the continued operation of the WTP and staff have identified this project as a critical project for completion. Some of the components of the SCP are obsolete and can no longer be obtained or repaired. City staff wants to investigate replacement of this equipment and the options available. We propose completing a technical memorandum outlining the options, timing and costs for replacement. Scope of Work Since a significant portion of this work is electrical related, we will be using electrical engineering services from Design Tree to assist with this project. Design Tree will be a subconsultant to Bolton & Menk on this project and we have teamed with Design Tree on many projects. We will request existing plans/specifications for the Navarre WTP for background info and then schedule a site visit. At the site visit we'll discuss the City's goals for the project and look at various options. One option we'll evaluate is replacement of equipment in -kind and in the same location. Another option is evaluating a building addition to house new electrical/controls as well as chemical feed rooms. Critical items to consider with any option is the operation of the WTP while the work is being completed as replacement of the electrical equipment will require the facility to be off-line for a period of time. We'll develop these and any other options and then develop a draft technical memo that will outline the background, options, project costs and project schedule. Once the draft memo is prepared, the draft memo will be shared with the City for City input. Once the City has provided feedback on the draft memo, we'll prepare a final memo for the City's consideration. Once a direction has been chosen, we can then develop scoping for the final design of the project. Final design fees are not part of this project scope.
