their plans for bidding the trunk utility improvements as a winter construction project to meet Lazydays RV's scheduled opening date of early May 2019. The plans call for service lines to be stubbed to several properties along Riverdale Drive so the properties can be served with municipal utilities in the future. These properties include the Lazydays RV sales building north of Riverdale Drive and east of Llama Street, the old Quality RV property north of Riverdale Drive and west of Armstrong Boulevard which is owned by Anoka County and has a failed septic system that cannot be repaired, and several properties south of Riverdale Drive and west of old Armstrong Boulevard that are owned by Anoka County who is working to transfer the properties to the City. Per City design standards, sanitary manholes are proposed to be constructed at 400-foot maximum intervals along the trunk sanitary sewer as needed for pipe deflections and cleaning purposes. Fire hydrants and gate valves are also situated at standard locations along the trunk watermain to enhance public safety. On December 11, 2018, the City Council approved plans and specifications and authorized advertising for bids for Improvement Project #18-14. At the time, construction costs were estimated at $460,000 with $285,000 attributed to trunk sanitary sewer improvements and $175,000 attributed to trunk watermain improvements. However, it was soon discovered that several cells of the cost estimate spreadsheet contained formula errors, which after corrections resulted in estimated construction costs being closer to $750,000. This error was discussed with the Public Works Committee on December 18, 2018. Advertisements for bids were published in the Anoka Union Herald and in Finance and Commerce on Friday, December 14, and again on Friday, December 21, 2018. Plans and specifications were also posted on-line on QuestCDN. Bids were originally set to be received on January 15, 2019, and presented to the City Council for award on January 22, 2019. However, in early January it was discovered that private utilities including CenterPoint Energy, CenturyLink, and Connexus Energy had already installed facilities in the same alignment as our proposed trunk utilities. Since this project is proposed to be completed during winter, impacts to private utilities are especially problematic as the ground surrounding the private utilities will be frozen making them impossible to relocate without first thawing the ground around them, which would increase the construction schedule and construction costs. Staff therefore issued an addendum moving the bid opening to February 5, 2019, allowing time to work with Civil Site Group to revise plans after realigning the trunk utilities south of the private utilities, avoiding impacts to private utilities as much as practical. Though this added three weeks to the bid schedule, the revised design allows for quicker construction and provides significant cost savings by preventing the need to remove and replace hundreds of feet of 10-foot wide bituminous trail on the west end of the project along Lazydays RV's maintenance facility site. Relocating the trunk utilities to the south requires an additional 10-foot of permanent utility easement along Lazydays RV's site to construct and maintain the trunk utilities. The property owner has willingly agreed to dedicate this easement via a utility easement agreement. The City Council was asked to accept this easement via a separate case on the consent agenda this evening. Upon accepting this easement, the trunk utilities can be adequately constructed and maintained. Attached is Exhibit B from the easement agreement depicting the easement area. On February 5, 2019, a total of eleven bids were received, opened, checked for errors and omissions, and tabulated. A summary of bids is below, including necessary adjustments as noted. None of the adjustments was significant enough to affect the order of award. All bids were found to comply with the advertisement for bids.
