Public Works Committee 5. 3. Meeting Date: 05/16/2017 By: Bruce Westby, Engineering/Public Works Title: Consider Recommending City Council Approval of Plans and Specifications for Improvement Project #17-03, 2017 Crackseal and Sealcoat Improvements Purpose/Background: Purpose: The purpose of this case is to consider recommending City Council approval of plans and specifications for Improvement Project #17-03, 2017 Crackseal and Sealcoat Improvements. Background: Attached are the plans for Improvement Project #17-03, 2017 Crackseal and Sealcoat Improvements. In total, crackseal improvements are proposed for approximately 0.24 miles of City streets, and crackseal and sealcoat improvements are proposed for approximately 13.41 miles of City streets. The plan includes a base bid, as well as 4 alternate bids. All streets colored magenta on the attached plans are included in the base bid, while streets colored orange are included in the 4 alternate bids, noted as alternates A through D. Staff will present this project in more detail at the meeting, including breaking down the rationale and costs for both the base and the alternate bids. Timeframe: Staff estimates 10 minutes will be required to present this case and respond to questions. Observations/Alternatives: Alternatives: Alternative # 1 — Motion recommending City Council approval of plans and specifications for Improvement Project #17-03, 2017 Crackseal and Sealcoat Improvements. Alternative #2 — Motion of other. Funding Source: A total of $500,000 was budgeted in 2017 for crackseal and sealcoat improvements, but as previously discussed with the City Council, staff would like to use approximately $35,000 of this budgeted amount to analyze existing pavement sections of all streets listed in the 10 year CIP that are identified to be reconstructed or milled and overlaid. In addition, Public Works staff rented a spray patching machine this spring and is requesting up to $35,000 of the $500,000 budget to pay for this work. This leaves a total of $430,000 for crackseal and sealcoat improvements. Estimated project costs for the base bid plus 4 alternate bids are attached to this case. Bidding the improvements in this manner should allow the City to award a contract for the base bid, plus a combination of one or more alternates, in an amount close to the $430,000 budget designated for this work. The estimated project costs include 14% indirect costs for administrative, engineering, finance, and legal costs. Recommendation:
