MN 55372 CITY COUNCIL AGENDA REPORT MEETING DATE: JULY 18, 2011 AGENDA #: 51 PREPARED BY: LARRY POPPLER, CITY ENGINEER PRESENTED BY: LARRY POPPLER, CITY ENGINEER AGENDA ITEM: CONSIDER APPROVAL OF A RESOLUTION AUTHORIZING FULL AND FINAL PAYMENT TO MCNAMARA CONTRACTING FOR THE 2010 STREET RESUR- FACING PROJECT CITY PROJECT #10 -012 DISCUSSION: Introduction The purpose of this item is to authorize full and final payment for the 2010 Resur- facing Project. This project included the resurfacing of the following streets in 2010: 1. Fremont Avenue, 2. Crossandra from Franklin Trail to Bounty Street, 3. Lords Street Neighborhood (Lords Street, Quaker Trail, Fairbanks Trail, and Edgewater Circle), 4. Rustic Road Neighborhood (Rustic Road, Maple Trail, Glendale Avenue, Oakland Beach Avenue, Kneafseys Street, Seven Acres Street, and Cove Avenue), and 5. Shady Beach Neighborhood (Shady Beach Trail and Bayview Circle). History In 2009, in an effort to quickly address deteriorating streets, the City Council ap- proved a new program in the Capital Improvement Program (CIP) to keep streets safe and useable until they can be reconstructed. The City had a 10+ year back- log of neighborhood street projects that were worthy of immediate reconstruction. The 2009 Transportation Plan, adopted as part of the CIP, proposed the resurfac- ing of streets in several neighborhoods to extend the useable life a minimum of 10 years to allow the City to catch up with the backlog of deteriorating neighborhood streets. The street resurfacing project involves making spot utility repairs which include replacement of valves and hydrants that are no longer functioning properly, along with any needed drainage repairs. The streets and infrastructure in this year's project area were originally constructed in the 1970s. Once utility repairs were made, the existing roadway was milled and leveled as needed to provide a surface for the new 1 Y2 -inch bituminous overlay surface. Because the subgrade of the road was not being reconstructed, this is a far less expensive construction me- thod. However, this resurfacing is not meant to be a long -term repair and the useable life for this type of activity is about 10 years. One of the issues with this method is that within a year or two of the resurfacing, cracks will begin to appear in the new surface where subgrade issues currently exist. Any cracks that appear will be sealed by the City as part of our annual crack sealing program to ensure the resurfaced area remains safe and useable for the 10 -year design life. In addition to the streets identified for the resurfacing program Crossandra Street and Fremont Avenue were included as they had been identified for resurfacing as part of the annual street maintenance overlay program. On April 5, 2010 the City Council awarded a contract to McNamara Contracting for the 2010 Resurfacing Project, ( #10 -012). All work under the contract has been completed in accordance with the contract. All punch list items have been com- pleted and any additional repairs will be covered under the project warranty. Current Circumstances The full and final payment is $88,938.35 more than the original contract amount. This accounts for approximately 14% of the original contract amount. The over- runs are due to changes in various project quantities primarily related to bitumin- ous, hydrants, and watermain valve replacement. On this project the Contractor encountered several additional valves and hydrants that did not work and needed to be replaced. Preliminary bituminous quantities were based on intermittent field measurements and not survey caliper drawings. Irregularities in the width of the street can lead to differences in the original quantities and final field quantities. In addition, in one area of the project a portion of the street settled. This settlement was not due to the work of the Contractor, but this segment of street was re- moved and replaced in 2011 increasing the final bituminous quantity. Conclusion Staff has confirmed these changes and recommends full and final payment to McNamara Contracting for the 2010 Resurfacing project. ISSUES: There are no issues with the final quantities for this project. FINANCIAL The original contract amount was $682,126.33. Due to quantity over -runs, the IMPACT: final contract amount is $771,064.68 or 14% over the original amount. Funding for this amount is available in the Construction Fund. ALTERNATIVES: There are three alternatives for the City Council to consider: 1. Approve Resolution 11 -XXX authorizing full and final payment to McNamara Contracting for the 2010 Resurfacing Project, City Project #10 -012. 2. Deny this item for a specific reason and provide staff with direction. 3. Table this item to a certain date in the future. RECOMMENDED Alternative #1.
