STAFF RECOMMENDATION Approve the change orders. Changing the transformer and generator feeds and other related equipment results in a savings of $9,973.00, changing the generator itself results in a cost increase of $12,813.57 but meets the requirements for Xcel Energy peak shaving purchasing credits with an estimated payback for the cost of the change order within three years.

ADMINISTRATORS COMMENTS City Administrator Date COUNCIL ACTION TAKEN: ❑ APPROVED ❑ DENIED ❑ OTHER Document2 City of Cotta Grove Minnesota To: Mayor and City Council From: Ryan R. Schroeder, City Administrator Date: .;anuary 24, 2012 Subject: PSCH Change Order Enclosed, please find two PSCH change orders recommended for positive consideration by Wold Architects. The first would result in a project construction savings of $9,973. The second would result in a project construction cost of $12,813.57 but would also result in an energy cost improvement. Changing feeders from the transformer and generator to the service disconnect from copper to aluminum, increasing conduit size to genset, and adding compression lugs and ground wire; also changing services from 70 amps to 60 amps. We had earlier approved a change order for aluminum feeds to the generator; at that time Wold recommended that additional research was necessary for them to provide a positive recommendation as they are now doing. This change order results in a cost reduction of $9,973. 2. Change the generator equipment to a peak shaving generator. The current proposed generator meets the contract specifications and 2011 code requirements. The proposed generator will allow the City to take advantage of Xcel peak shaving credits; in other words to allow Xcel to place the building power on our generator which will result in Xcel purchasing that opportunity from the City. Wold estimates that the purchase credits will result in a payback for the cost of this generator within three years. This change order results in a construction cost increase of $12,813.57 Recommendation: Wold recommends positive consideration of both of these change orders. The construction team has also reviewed these change orders. Council Action: By motion authorize PSCH change orders in the amount of ($9,973) and $12,813.57 as noted above.
