$740,775.65. January 26, 2016 Page 4 of 6 I to 150946. Motion by Councilmember Burg, seconded by Councilmember Jacobsen to approve the Consent Agenda as presented. 5 Ayes, 0 Nays - Motion Carried Public Hearing None. Council Business 1. Consideration of Work Order 2 for Design, Procurement and Construction Phase Services to Implement AOP Technology at WTP 1. City Manager Lotter indicated reported on August 11, 2015 the City entered a Master Professional Services Agreement and Work Order No. 1, with Barr Engineering. Under the scope of Work Order No. 1, Barr Engineering evaluated and screened the broad range of potential technologies that may be applicable for treatment of 1,4 -dioxane. That work included literature reviews, collection and evaluation of information from technology vendors, evaluation of operating facilities, and bench scale testing. That screening process identified two specific technologies that are currently undergoing treatability testing in a pilot scale setting, at the City's Water Treatment Plant number 1 (WTP1). The pilot testing is expected to be complete by early May. The testing will be used to compare technologies and to help the City select which technology it wants to implement to remove 1,4 -dioxane. The Project described under Work Order Number 2 (Barr 423621176-02) consists of integrating the selected AOP technology into the City's existing water treatment processes at WTP I, along with all necessary site and treatment plant modifications. The nature of the Project, along with schedule constraints, regulations governing the procurement of goods and services, and other considerations, makes it advantageous to deliver the constructed Project in multiple Contract Packages. Each Contract Package consists of a portion of the Project that can be procured and completed separately. A full description of the work involved in each Contract Package is included in the body of Work Order No. 2 that is enclosed as an attachment. The anticipated schedule for each Contract Package is also enclosed, and that schedule shows construction completion in the fall of 2018, which is consistent with previous presentations. Staff reviewed the request further and recommended Council authorize the Mayor and City Manager to enter into the work orders. Greg Keel, Barr Engineering, provided the Council with a presentation on the professional services his company would be providing to the City and further defined the work that would be completed within Work Order No. 2. He updated the Council on the treatability study status from Work Order No. 1. It was noted the pilot testing would end mid-April and a report from the findings would be completed by June 2016. At that time, the City will decide which AOP to implement. He explained a Minneapolis interconnection would provide the City with a backup emergency supply to be used for replacement supply instead of the City's wells, if needed. The proposed flow of water through the new treatment plant was reviewed with the Council and commented the project would be implemented through multiple contract packages. He estimated the constructed value of the project to be $20 million and anticipated the engineering expense to be roughly $3 million. He reiterated that each of the four contracts would be coming back to the Council for approval in the near future. Councilmember Bauman thanked staff for the thorough presentation. She supported the Minneapolis interconnection and asked if any additional filtration would be needed. Mr. Keel reported Minneapolis receives its water supply from the Mississippi River.
