Home My WebLink About9A Resolution Accepting Quotes for Sanitary Sewer Project 11-015FRI U r 4646 Dakota Street SE '�INxESol Prior Lake, MN 55372 CITY COUNCIL AGENDA REPORT MEETING DATE: MAY 16, 2011 AGENDA #: 9A PREPARED BY: JOE WIITA, STREET AND UTILITIES SUPERVISOR PRESENTER: JOE WIITA AGENDA ITEM: CONSIDER APPROVAL OF A RESOLUTION ACCEPTING QUOTES FOR THE BORING, EXCAVATING AND INSTALLATION OF STANDARDIZED EQUIPMENT FOR THE 2011 SANITARY SEWER PROJECT 11 -015 DISCUSSION: Introduction The purpose of this agenda item is for the City Council to accept quotes for the boring, excavating and installation of appurtenant equipment for the 2011 sanitary sewer improvements. Hi story This agenda item is part of the continuing process of completing the new Watersedge Lift Station Project 11 -015. Work to be completed is due to the age, condition and multiple issues that have occurred with the inverted si- phon that is currently in place on Watersedge Trail. Upon completion of this project the City will have 40 sanitary sewer lift stations. On February 22, 2011 City Council adopted resolution 11 -026 authorizing staff to proceed with the design and specifications of the 2011 Sanitary Sewer improvements. Additionally, on April 4, 2011 City Council adopted resolution 11 -040 accepting plans and specifications and authorizing staff to solicit quotes for this project. The standardized equipment, boring and excavation will follow the City of Prior Lake's Lift Station Standardization Management and Rehabilitation Plan and will include pumps, guide rails, electrical panels, wet well and valve vault covers and hatches. In addition to reducing liability, this project allows the City to minimize and prevent the inflow of ground water into the City's sanitary sewer system. By minimizing this inflow, the City minimizes sewer treatment costs with the Met Council. Current Circumstances On May 2, 2011 City Council approved resolution 11 -056 accepting quotes for the purchase of standardized equipment for the 2011 Sanitary Sewer Project 11 -015. Quotes were received on May 4, 2011 for boring, excavating and the instal- lation of the standardized equipment. Quotes for the excavation and installation are as follows: Contractor Quiring Excavating S. M. Hent es GM Contractin Chard Tiling Total $44,389.00 $46,877.00 $79,684.22 Passed /Denied Quotes for the boring are as follows: Contractor MinnComm Ellingson GM Contractin Total $11,952.00 $19,220.00 $40,250.88 City staff will act as the general contractor and supply all components and equipment based on the Lift Station Standardization process. Staff will complete and schedule all preparatory work, excavation and restoration of the construction site. Conclusion Because the City is reconstructing Watersedge Trail in 2011 it is appropriate to make the improvements to the sanitary sewer lake crossing concurrently to eliminate current sewer back -up issues and provide long -term dependa- ble sewer service to this area. Staff is recommending Quiring Excavating and MinnComm to complete the boring, excavating and installation services as they provided the lowest quotes respectively. All work for this project will be completed by Septem- ber 1, 2011. ISSUES: If the City does not make this upgrade in conjunction with the 2011 Boudin's Reconstruction Project, the City will most likely need to excavate a portion of the reconstructed Watersedge Trail to make repairs in the next 10 years. Without replacing the crossing the existing sewer grade issues can't be re- paired and back up issues will continue. The Duluth Avenue sanitary sewer repairs as approved in the 2011 -2015 CIP would be delayed to a future date and discussed in the 2012 -2015 CIP; and the funds budgeted for Duluth Avenue would instead be used for this Watersedge project. City staff believe that the Watersedge Lift Station con- struction is of greater priority than the Duluth Avenue repairs at this time and this project also coincides with the 2011 Boudin's reconstruction project. FINANCIAL With the City as general contractor, considerable money will be saved by IMPACT: not paying mark up costs for equipment and components for the lift station. Costs related to contract services amount to $56,341.00. Costs for stan- dardized equipment to complete the project come to $81,858.77 which cov- er the following items: • Controls • Structure • Hatches • Valve Vault • Pumps • Guide Rails /Support The total project costs for the purchase of standardized equipment, boring, excavation and installation is $138,199.77. The 2011 Sewer Fund budget identifies $150,000 for sanitary sewer system improvements for the Duluth Avenue and $55,000 for lift station panel and equipment installation. The work for the installation of this lift station will not exceed budget for these two line items identified in the sewer budget. ALTERNATIVES: 1) Approve a resolution accepting quotes and authorizing the execution of two City Standard Construction Contracts: one with Quiring Excavating in the amount of $44,389.00 for excavation and installation of City sup- plied standardized equipment; and one with MinnComm for $11,952.00 for the boring of a forcemain for the 2011 Sanitary Sewer Improvement Project 11 -015. 2) Defer this item for a specific reason and provide staff with direction. 3) Direct staff not to proceed with the project.
