HomeMy WebLinkAbout#11 - Heritage Farms Street & Utility STAFF REPORT DATE: August 4, 2020 CONSENT AGENDA ITEM: Authorize Final Design Services to Rebid the Heritage Farms Street and Utility Improvements SUBMITTED BY: Jack Griffin, City Engineer REVIEWED BY: Kristina Handt, City Administrator Marty Powers, Public Works Director Chad Isakson, Assistant City Engineer ISSUE BEFORE COUNCIL: Should the City Council authorize Final Design Services to rebid the Heritage Farms Street and Utility Improvements? BACKGROUND: The City Council approved the plans and specifications and authorized the advertisement for bids for the Heritage Farms Street and Utility Improvements at the March 4, 2020 council meeting. The improvements include the extension of municipal sanitary sewer to serve the 44 residential properties in the Heritage Farms subdivision and to repair and upgrade the existing public watermain. Following the utility improvements, approximately 1.2 miles of public streets will be reconstructed, including Lisbon Avenue North, from 30th Street to the south end; Lisbon Avenue Court North, from Lisbon Avenue to the end of cul-de-sac; and 30th Street Circle North, from 30th Street North to 30th Street North. Contractor bids were received on April 2, 2020 resulting in post-bid estimated total project costs exceeding the estimated feasibility total project costs, and subsequently the preliminary assessment amounts to be levied against the benefitting properties. Due to the high bid prices, the council rejected all bids at the April 21, 2020 council meeting and directed staff to prepare the project for rebidding at a time as recommended by city staff. Based on some preliminary analysis and discussions with contractors it was determined bidding in fall 2020 for construction in 2021 was the appropriate schedule to follow. PROPOSAL DETAILS/ANALYSIS: In order to prepare the project for rebidding, the plans and specifications, including the contract documents, must be amended to address the updated schedule for the work, including permit reapplications and other requirements for project implementation. Staff is further recommending that the rebid package include value engineering based on the previous bid prices and contractor feedback received regarding the high bid prices. In addition to minor design changes and value engineering, the rebid package will also include an alternate bid for a secondary sewer design that will allow the council to compare alternative layouts and costs. The alternate design includes raising the sanitary sewer elevation up for shallower installation. The result of this effort will place anywhere from 5-11 homes on individual pump systems. The goal is to get a true cost difference between the systems to assist in deciding what is viable financially to serve this neighborhood with municipal sanitary sewer. FISCAL IMPACT: $40,300. Authorizing the preparation of plans and specifications commits the City to incur the engineering costs above what has been spent to date. The additional design costs are necessary to complete a bid package and alternate design for contractor bids, to ready the project for construction in 2021. It includes authorization for TKDA to complete design efforts in the amount of $25,300, FOCUS Engineering to re-engage the property owners, coordinate easements, and oversee design options in the amount of $8,000, complete a wetland delineation by a consultant to be named later in the amount of $3,500 and complete infiltration basin testing in the amount of $3,500. The Heritage Farms Street and Utility Improvements is an infrastructure project that will be partially assessed against the benefitting properties consistent with the City’s Special Assessment Policy. The project is funded through the issuance of general obligation bonds and special assessments. The council will be asked to award a contract for construction in December 2021, at which time the City would be asked to commit to the remaining project costs. RECOMMENDATION: Staff is recommending that the City Council authorize, as part of the consent agenda, final design services to rebid the Heritage Farms Street and Utility Improvements. If the item is pulled from the consent agenda, the recommended motion for this action is as follows: “Move to authorize final design services to rebid the Heritage Farms Street and Utility Improvements in the not to exceed amount of $40,300.” ATTACHMENTS: 1.
