Item No: 7E Meeting Date: March 12, 2012 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 7914, Awarding a Construction Contract to Rosenquist Construction, Inc. for 2012 Reroofing of Community Center and Water Treatment Plant No. 1 Project Background: In response to aging and leaky roof issues the past few years, a comprehensive roof management program (Program) was prepared in 2010 for all sixteen City-owned buildings. The Program recommended that full reroofing for the Community Center and Water Treatment Plant (WTP) No. 1 occur in 2012. A section of the Public Works Maintenance Facility (over the original building) is also recommended to be replaced in 2012, but City staff recommends a “repair as needed” approach since the Capital Improvement Program includes demolition and reconstruction of this building in 2016. In October 2011, the City Council authorized INSPEC, Inc. to design and prepare bidding documents for reroofing of the Community Center and WTP No. 1. The City Council approved the bidding documents and authorized advertisement for bids for the project on January 23, 2012. An ad for bid was published in the February 2 and 9, 2012 editions of the Sun, and in the February 2 edition of Finance and Commerce. Discussion: A public bid opening was held on February 23, 2012 for the 2012 reroofing project. The City received 12 bids from qualified contractors ranging from $267,000 to $482,793 (see attached bid tabulation). The low bid was submitted by Rosenquist Construction, Inc. of Minneapolis and included bids of $222,000 and $45,000 for the Community Center and WTP No. 1 work, respectively. Rosenquist was contracted by the City for last years’ reroofing of City Hall and Well House No. 5 and 6. The City’s consultant, INSPEC, and Public Works staff were very pleased with Rosenquist’s performance on that project. Contingency unit prices were also solicited in the bidding process for adjustments in the quantity of insulation replacement and additional skylight domes (Comm. Center only). These prices were requested since actual condition of some the existing rigid insulation will not be known until demolition of the roof and removal of the skylight domes. The adopted 2012 Budget includes $250,000 under Special Projects (280-4180-7050) for Community Center reroofing and $50,000 under the Water Enterprise Fund (700-4823-7050) for WTP No. 1 reroofing, for a total combined budget amount of $300,000. INSPEC has provided an hourly fee estimate of $14,000 for construction administration, observation, and inspection services during construction, bringing the estimated project cost to $281,000. The remaining balance of $19,000 is recommended to be used as a construction contingency (7%) in the event that unknowns are discovered during construction, whereby allowing staff to act quickly to address these issues when the roof is most vulnerable. Any use of contingencies will need pre-approval by the Public Works Director. The proposed schedule for construction may begin as early as April 2012 but needs to be substantially complete by June 1, 2012 and final completion by June 22, 2012.
