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.
