Chanhassen is a Community for Life - Providing for Today and Planning for Tomorrow Todd Gerhardt West Water Treatment Plant: Award Contracts October 24, 2016 Page 2 DISCUSSION The plant has been designed for the ultimate treatment capacity needs of the city and will bring all the western wells and future wells to the plant for iron and manganese filtration. The iron and manganese filtration plant is planned for a total capacity of 6,000 gpm. The plant is proposed to have a process that is very similar to the gravity cast -in-place treatment process as the East Plant to provide consistency in the plant operations and finished water quality. A detention basin is included in the design to improve the filtration process efficiency. The plant is designed so treated water will be able to be pumped in the low and high pressure zones. Water Treatment Plant Bid Bids for the water treatment plant include all building improvements and site work for the project. Bids for the treatment plant project were opened on Tuesday, October 18, 2016 at 2:00 p.m. Four sealed bids were submitted and read out loud and checked for errors. The bids received are as follows: Bidder Total Bid Rice Lake Construction Group $13,880,600.00 Gridor Construction, Inc. $14,872,700.00 Knutson Construction Services, Inc. $14,933,000.00 Magney Construction, Inc. $15,019,400.00 The Engineer's estimate was $17,533,000.00 which included a 10% contingency. Alternative bids were included in the bid tabulation. These alternative bids included pricing for adding three months to the project schedule, removing retaining walls from the site improvements, cost breakout for chemical feed systems, pricing for different filter media and using an alternative floor coating. Staff is not recommending accepting any of the alternative bids. Rice Lake Construction group has not worked for the City. Rice Lake Construction Group is one of the largest water and waste water plant construction contractors in the state of Minnesota. The City's consultant, WSB & Associates, has checked references and recommends award of the West Water Treatment Plant contract to Rice Lake Construction Group. Water Main Improvements for the Water Treatment Plant Water main will need to be installed along Galpin Boulevard to distribute the filtered water to the low and high pressure zones. Water main is also required to be connected from Wells 415 and #3 and bring this water to the treatment plant for filtering. Bids for the water main improvements associated with the treatment plant were opened on Tuesday, October 18, 2016 at 11:00 a.m. Four sealed bids were submitted, read out loud and checked for errors.

Staff recommends accepting the GF Jedlicki, Inc. bid with Alternate 1 in the amount of $1,164,539.00. Building Security Contract Security system improvements were separated from the building contract to reduce cost and to work with the security firm that the City has used on all other facilities. Scope of the work includes furnishing and installing access controls, intrusion alarms and video surveillance for the facility. Pro -Tec Design has worked with the City on standardization of security systems for other City facilities. Their work has been acceptable.
