Recommendation Based upon the information included therin,we are recommending that the City Council take action on the following items: 1. Award the contract for construction of the Rosemount City Hall Roof Replacement to John A. Dalsin Construction for the amount of$234,000 which is the total of the base bid and alternates#1 and#2. Background The public bid opening for this project was held on Tuesday,July 29,at City Hall. A total of three bids were submitted, opened individually, and then read out loud to those that were in attendance. All of the bids that were received were considered responsive bids. Upon receiving these bids, CNH Architects conducted a post bid"interview"with the low bidder, John A. Dalsin Construction. We have determined that this bidder has a complete and responsive bid, and that this company is a qualified roofing contractor for a project of this scope. The total contract amount to be awarded to John A. Dalsin Construction is as follows: Base Bid $214,000 Alternate#1 $ 16,500 Alternate#2 $ 3,500 Total Contract $234,000 CNH Architects is recommending the acceptance of alternates#I and#2 for installing insulation at P:\Projects\2014\14017\4-Bidding\Recorrmendation to Award Contract.doc areas of the roof overhang and roof to wall construction based on the data shown in the thermal imaging study done by Braun Intertec. This study showed significant localized heatloss at these specific locations which pointed to gaps and under-insulated areas in the original construction. The insulation systems included in these alternates would be required to meet building codes if built today. Since this insulation cannot be installed in the future without removing the standing seam roofing panels at the facias, CNH Architects recommends doing this work at this time. While a payback period for energy savings is not easily quantified with the information available, our professional opinion is that insulation work will result in sufficient energy savings to pay for itself over the life of the new roof. Please let me know if you need any additional information prior to the meeting. Thank you for this opportunity to work with the City of Rosemount. Respectfully submitted, 0_2 Quinn S.
