Postpone consideration of bids until 9/24 meeting. Item 8.3 9/24/07 Motion to reject bids for construction of a sanitary sewer lift station (improvement project 833). Reject bids COUNCIL Request for Action Originating Department Approved for Agenda Agenda Section Public Works August 13, 2007 Develop & Plannin Item No. 8.1 By: Guy Johnson By: Resolution awarding contract for construction of a sanitary sewer lift station, contingent on the proposed Prairie Ridge housing development's purchase and development agreement (improvement project 833) Requested Action Staff requests approval of a resolution awarding the contract to the low and responsible bidder, Doboszenski & Sons Inc., in the amount of $86,554.50. Staff also recommends that the awarding of the contract be contingent on the proposed Prairie Ridge housing development's purchase and development agreement. Background In April of 2006, Council authorized staff to initiate a request for proposals for the development of single family homes on city owned property near 52nd and Pennsylvania avenues north. Also in April of 2006, Council authorized $3,500 for the city engineer to complete a preliminary boundary survey of the site to be used with potential developers in the request for proposal process. Through the request for proposal process and discussions with the Council, it was determined that the prospective developer would be responsible for the construction of all street and utility infrastructure. On September 25, 2006, Council passed a motion authorizing staff to negotiate an interim agreement with Avalon Homes. Staff and the city engineers have worked with Avalon Homes to develop preliminary site plans. During the design process of the overall site elevations and the individual building sites' elevations, it was determined that the city's existing sanitary sewer pipe at the west end of the property was not deep enough to receive sewer flows from a number of building sites on the east end of the development. Motion by /�°, -�� Second by To: r I C ( C I: \RFA \PUBWORKS \2007 \833 Prairie Ridge L.S. Award Contract.doc Request for Action August 13, 2007 Page 2 Staff and the developer considered two options to resolve the issue of sanitary sewer services for the east end of the development. The preferred option was to review the possibility of connecting these building sites to the city of Crystal's sanitary sewer collection system on Louisiana Avenue using gravity flow. Staff met with Crystal's engineering staff to discuss this option. Crystal's staff agreed to look into the feasibility of a connection to their sanitary sewer collection system. After reviewing their sanitary sewer collection system in the area between 52nd Avenue and Bass Lake Road, from Louisiana Avenue down stream to Douglas Avenue, it was determined that their system could not handle the additional volume. With that determination, the only remaining option is the installation of a sanitary sewer lift station on city property in the southeast corner of the proposed development. The lift station will receive sewer flow from the homes on the east end of the site and pump the sewage through a force main into a manhole with gravity flow located in the west half of the development. The lift station's plans and specifications that the Council approved on March 14, duplicate the city's existing lift stations throughout the city. Duplicating the rest of the city's lift stations, and their SCADA systems, will help to ensure efficiency in long -term lift station operations and future maintenance needs. The developer will be responsible for their collection system's connection to the city's lift station and the connection of the lift station's force main to the manhole with gravity flow in the street right -of -way. The developer will also be responsible for the installation of all necessary sanitary sewer infrastructure for the individual building sites and the collection system in the road right -of -way, including the connection of the development's gravity flow system to the city's existing sanitary sewer pipe at the west end of the development. Bids were received from four contractors, with Doboszenski & Sons Inc. being the low responsible bidder, at $86.554.50. The project involves the developer's contractor constructing the lift station infrastructure and the sanitary sewer force main that would later be connected to the sanitary sewer gravity collection system. Staff is recommending that the electrical control panel and SCADA system be constructed by the city's current 2007 SCADA system contractor through a change order. A breakdown of the total cost estimates is attached in the engineer's project memo. Funding Funding for the lift station would be from the EDA.

The development will be supported by extending existing utilities and constructing an east -west road through the site with connections to both Pennsylvania and Louisiana Avenues. Avalon Homes is the developer for the project and MFRA, development engineers, is completing the design for the infrastructure and site work. In the initial stages of the marketing the property, the City completed a preliminary boundary surrey of the property. Engineering staff also assumed that the trunk water, sanitary sewer, street, and storm water utilities could all be extended and constructed efficiently to serve the proposed development. Cost estimates were prepared for these infrastructure extensions and were presented to developers during the marketing phase. The design of the infrastructure was not completed at that time. During the analysis and design phase of the project, MFRA notified the City that the street, water, and storm infrastructure could be constructed generally as anticipated. However, the existing trunk sanitary sewer extending through the west side of the property was too high to provide gravity sanitary sewer service to all the proposed homes within the development. To resolve this issue, it was proposed that the homes on the east end of the development be served by connecting a gravity sewer to the existing sanitary sewer in the City of Crystal. Due to capacity issues with the existing system, the City of Crystal said that a connection contributing additional flow would not be feasible. Elimination of this option resulted in the need for a lift station to service a portion of the homes in the proposed development. It was determined that services from 12 of the 17 homes be routed to the lift station. The lift station did provide some cost savings to the proposed development as the connection to the Crystal system was not required. This eliminated the need to reconstruct a portion of Louisiana Avenue. The cost savings were determined to be $33,046.30. The developer will be responsible to contribute an amount equal to these savings towards the cost of the lift station. Lift Station Project Coordination The lift station and force main were bid as a City project to facilitate consistency with other city lift stations. The bid was coordinated with the development schedule. To facilitate the targeted schedule for occupancy of the first home, the electrical (control panel) work was removed from the lift station project bid and added via change order to the Lift Station Control Panel contract involving similar work at other lift stations. Completing the Prairie Ridge control panel via this change order will also assure the control panel is consistent with other City lift stations. Consistency in these facilities is an important attribute from an operation and maintenance perspective. Project Bids and Costs Bids have been received for the lift station work. The general contractor selected to do the development grading and infrastructure was also the apparent low bidder on the lift station. One general contractor for all of the work will improve coordination. A quote for the control panel is also being requested from the contractor working on the control panel contract. No recent contact has been made with Exel regarding the electrical service.
