HomeMy WebLinkAboutItem 06.cDate: 28 April 2014 0 Item No. APPROVAL OF AN AGREEMENT WITH SHORT ELLIOTT HENDRICKSON (SEH) FOR DESIGN PHASE AND CONSTRUCTION PHASE ENGINEERING SERVICES FOR THE CONTRUCTION OF A NEW 2.0 MILLION GALLON WATER STORAGE TANK Proposed Action Staff recommends adoption of the following motion: Move to approve an agreement with SEH for design phase and construction phase engineering services for the construction of a new 2.0 million gallon water storage tank. Passage of this motion will allow for the preliminary design work, geotechnical services, and construction administration and observation necessary for the design and construction of a water storage tank. Overview In 2013, SEH updated the City's comprehensive water supply plan recommending that additional elevated water storage be built in Lakeville to be able to adequately serve residents in the normal pressure zone. The location for construction at the intersection of 190' Street and Holyoke Avenue was based on the location with the best hydraulic connectivity to the water system. Short Elliott Hendrickson has been involved in the engineering and construction of the Michaud Park tower and the Central Maintenance Facility tower and is familiar with the City's water system and comprehensive plans. They are also part of the City's pool of consulting engineers. Cost for design, bid, and construction administration and observation services to support construction of a new elevated water storage tank is $221,350.00. Staff has reviewed the proposal and recommends approval. Primary Issues to Consider Is additional water storage necessary? Yes, considering the growth of the City and forecast demand, the ability to meet the needs of those in the normal pressure zone is important.
