Westside Interceptor Sch 4 and 5201 P Avenue East PO Box 1997 Kalispell, MT 59903 Phone: 406-758-7720 Fax: 406-758-7831 www.kalispell.com /public_works MEMORANDUM TO: Doug Russell — City Manager CC: Susie Turner, PE — Public Works Director FROM: Keith Haskins, PE — City Engineer SUBJECT: Recommendation for Award — Schedules 4 & 5 - WSI BACKGROUND: The Westside Sewer Interceptor project is intended to serve existing and new flows from a large service area in the western and northern portions of the city. Construction of the WSI will accomplish the following objectives: 1. Two existing deviations with the Montana Department of Environmental Quality which limit growth in certain areas of the city will be satisfied with the completion of the WSI; 2. Flows north of Reserve Drive will be diverted to the interceptor, decreasing downstream impacts in the collection system; 3. Flows in portions of Line A will be reduced, providing additional capacity necessary to serve existing infill areas and provide opportunity for needed maintenance repairs; 4. Three existing lift stations will be removed, saving associated manpower, and overhead and management costs; and 5. The City will have appropriately sized sewer collection infrastructure to serve as a main artery for new growth areas in the north and west portions of the City. The project has been separated into 5 separate schedules to ensure project completion by the end of the calendar year. A staggered bid opening was applied to the project to give bidders additional time to prepare their bids as well as refine their prices between bid openings of the separate schedules. Schedules 1 through 3 were awarded at the Council Meeting on May 7tn Schedules 4 and 5 were opened May 3`d, and the awards of the contracts were postponed to allow a thorough review of the bidding documents and references. Schedule 4 of the WSI includes installing approximately 4,000 linear feet of 27 inch sewer main, approximately 8,200 linear feet of 24 inch sewer main, and approximately 2,600 linear feet of 21 inch sewer main. This schedule also includes sanitary sewer manholes, sanitary sewer main / service connections, paved surface restoration, concrete restoration, and landscape restoration.

Also included in this schedule are sanitary sewer force main connections, paved surface restoration, concrete restoration, and landscape restoration.
