Item No: 7N Meeting Date: December 14, 2009 Type of Business: Council Business Administrator Review: ____ City of Mounds View Staff Report To: Honorable Mayor and City Council From: Nick DeBar, Public Works Director Item Title/Subject: Resolution 7546 Authorizing Construction Contract for City Hall Electrical Service Entrance Modifications Background: In 2005, the City adopted the Ramsey County Emergency Operations Plan that identifies the City Hall building as the Emergency Operations Center (EOC). The EOC is the command post in the event of any local disaster (tornado, blizzard, etc.) or search and rescue operations. The City Hall building does not have a means for emergency backup power in the event of a power outage, which often occurs during natural disasters, making it very difficult to be utilized as the EOC. The purchase of a 150-kW mobile emergency generator was approved by the City Council, purchased, and delivered this past year. This generator was specified to be used for multiple facilities, including the water treatment plants/wells, sanitary lift stations, and City Hall. Public Works Staff has been properly trained in its use and with exception to a few outstanding punch list items, the generator is ready to go. Discussion: Modifications are needed to the electric supply entrance to City Hall before the emergency generator can be used to power the City Hall building. Bonestroo was hired to prepare a Project Manual (plans/specifications) for the modifications needed to allow the generator to work at City Hall. There are a few different setup options, including a manual or automatic transfer switch among other things. It was recommended to have a manual transfer switch at the City Hall, which will require a switch, or lever, to be engaged by hand for proper transfer of power from Xcel Energy’s supply to emergency generator supply. Bids for the work were received on December 10, 2009 from three qualified electrical contractors. A base bid for the work was requested, as well as an add alternate bid for a voltage surge suppression device. The bids received (base bid + add alternate) were in the amounts of $17,525, $21,450, and $26,545. Bonestroo had an engineer’s estimate of $25,000. Hymark Electric of Stacy, Minnesota submitted the low bid. A letter from Bonestroo detailing bid results is attached to this report. The electric service entrance modifications have been included in the Capital Improvement Program and are part of the adopted 2009 Budget under Special Projects (280-4180-7050) for $50,000. The total estimated project cost is estimated at $22,225 ($17,525 + $4,700 engineering fees) – well below the budgeted amount. Staff recommends the City Council also include a 10% construction contingency be added to the construction cost for minor work associated with unknowns that could occur during construction. This contingency would add an additional $1,755 (10%x$17,525) to the $17,525 for a grand total authorized amount not to exceed $19,280.
