PROBLEM/ISSUE STATEMENT
Mayor and Council are asked to consider awarding a professional engineering services contract to Morrison-Maierle, Inc. (MMI) in the amount of $272,188.00 for design and construction administration services on the 2011 Chapple Area Water Main Improvement Projects. Water mains would be replaced and/or added in various locations north of Rimrock Road in the vicinity of Chapple Pump Station as identified by City staff and by the results of distribution system modeling performed during project design. MMI was selected based on City staff review of project proposals submitted by prequalified firms. Other firms considered for the work were Sanderson Stewart and DOWL-HKM.
This is a scheduled Capital Improvement Project to improve fire flow to residences in the vicinity of Chapple Pump Station. Due to the combination of higher area elevations, older 4-, 6-, and 8-inch water mains, excessive head loss, and some lack of distribution system connectivity, several areas of the distribution system in this neighborhood do not meet minimum fire flow requirements. Approximately 6,000 feet of water mains will be replaced and/or added as identified by City staff and the results of distribution system modeling performed under the design phase of this project.
