Both of these facilities require updates and maintenance projects to ensure the City can provide water to the residents and this project includes many different improvements to the facilities. The most significant improvements include updating the chemical feed system which include improvements to meet current Minnesota Department of Health requirements. The improvements include various building maintenance items such as replacing roofing, new doors, miscellaneous painting and new electrical and HVAC improvements. New valves and piping and improvements to the aeration system at the Navarre facility also are part of the project. Four(4)bids were received for the construction of the Water Treatment System Improvements project.The bids ranged from $625,000 to $754,300 as shown in the attached Bid Tabulation. The apparent low, responsive and responsible bidder is Municipal Builders,Inc. from Andover, MN. The original Engineer's estimate for this project was $450,000.00 based on the October 2013 Water System plan. This estimate is over a year old and construction pricing has increased 20 plus percent in the past year. In addition, the current project includes upgraded chemical feed equipment to allow for automatic metering and control of the chemical dosing at both facilities. This will allow for better dosing of the treatment chemicals and better operation of the system. The project also includes new submersible well transducers,piping and associated electrical work for each of the three wells. The transducers will record the water level in each well and recording water level in wells is a requirement of the Minnesota Department of Health. The chemical feed equipment and well transducers add approximately $75,000 to the project costs. Add in the construction cost increase and the as-bid costs are in-line with the Engineer's estimate. We feel that the bids received were competitive and responsive and re-bidding of the project would not provide any cost savings. 'The two low bidders were within four percent of each other and the three low bidders were within six percent of each other. In our opinion, Municipal Builders, Inc. is experienced in the type of work reyuired for this project. The company has fulfilled the bidding and contract requirements and we recommend that their bid in the amount of$625,000 be accepted. Municipal Builders, Inc. has been in business since 1993 and they specialize in the municipal water and wastewater construction market. Municipal Builders, Inc. completes approximately $6 to $8 million of work every year and they have completed many projects that are similar in nature, size and scope to the H:\ORNO\C1310861'7�1 Corres\C To Others\bid eval.docx OESIGNlNG FOR A BETTER TOMORROW Bolton&Menk is an eyual opportunity employer
