FROM: DATE: July 13,2009 SUBJ: Public Works Facility, Project 08-03: Approve Change Order PROPOSED MOTION "The City Council approves Change Order No.1 in the amount of $43,479.35 for the Public Works Facility. City Council approval requires a simple majority vote of the City Council present. BACKGROUND On February 23,2009, the City Council approved the plans and specifications and authorized the ad for bids. On March 23,2009, the City Council approved bids for steel and concrete for the facility and reviewed other bids and quotes. On April 13, 2009, the City Council approved bids and quotes for the remaining items of the facility. DISCUSSION Staff is requesting Council consider approving a change order for the Public Works facility. Included in this request are minor miscellaneous changes to the project caused by unforeseen site conditions or requested changes by the Building Department based upon interpretation of the building code. Contract changes like these are normal for large scale projects. The City's construction manager RJM Construction has reviewed the costs and finds them consistent with current market pricing. Below is a brief description of the changes requested: Men's and Women's Shower Revisions $644.00 This change was requested by the Building Department based on their interpretation of the plumbing code. The change reconfigures the shower stall and extends a wall. Chanhassen is a Community for Life - Providing for Today and Planning for Tomorrow Todd Gerhardt Public Works Facility: Approve Change Order July 13,2009 Page 2 Add Storm Sewer Catch Basins and Storm Sewer Piping $16,615.50 In the design that was bid, the roof leaders for the west side of the building drain off the building into a shallow swale which drains to the south. During construction of the footings in this area, the water table was observed higher than the soil borings indicated. It is believed if the rain water leaders are left as is and the runoff of the building is left to drain in the swale, the water table in this area could increase and potentially cause foundation problems in the future. The proposed change will connect the roof leaders to a storm sewer pipe and drain to the south. The storm sewer pipe is also proposed to be perforated so it will act like a drain tile to pick up groundwater. Add Practical Row of Recon Retaining Wall Block $728.00 The southeast wall next to the parking lot needed to be raised one course to better match the back of curb of the parking lot. Watermain Connection This change is a deduction in the piping contract for water service to the building. deduction of a wet tap. -$1,274.00 The change is for the Six Additional Skylights $20,985.00 This change is to include six skylights to the fleet storage area which were left out of the original contract. The fabrication of the skylight openings were added into the steel bid but were inadvertently not added into the roofing contract at the time of award. The skylights pricing was competitively bid out with the roofing contract. Deduct for HV AC Permit Fee This item is a deduction in the HV AC contract for the permit fee. -$6,018.15 Add Footing Steps $8,939.00 This item is to lower the footing and add steps to facilitate changes to the stormwater roof leads on the west side of the building. Add Resinous Flooring to Hallways 122, 13 Land 131 In Lieu of Tile $2,290.00 This item is requested by the public works staff. It is felt the resinous flooring will be easier to maintain and clean than the tile flooring that is currently in the contract. The office areas, bathrooms and lunch rooms all have the resinous flooring. The only area that will have tile is in the reception area. Underground Conduit for Future Fiber Optic Cabling $570.00 This item is to add conduit under the east drive and the west drive to plan for future fiber service to the facility. The City is currently working with Carver County on a fiber loop for the County. The City is looking at using the County's fiber loop in the future for City operations. The fiber will potentially be installed next year after the facility is open. Staff does not have a final plan from the County were the fiber will be installed. The facility will have a temporary network connection until the fiber is installed. Total Requested Changes $43,479.35 The change order amount is proposed to come out of the contingency amount budgeted for the project. The project is still projected to be under budget by $390,256.
