Historv On June 21, 2010, the City Council passed Resolution #10-059 authorizing the preparation of the Feasibility Report for the 2011 and 2012 Improvement Project. The Feasibility Report will address street reconstruction in the Boudin's neighborhood. In particular for the following streets: Boudin Street, Denese Street, Grayling Circle, Lois Avenue, Natalie Road, Rutgers Road, Timothy Avenue and Watersedge Trail. In anticipation of these projects the City of Prior Lake must perform surveying and soil analysis. City staff has asked the consultants proposing on these items to provide costs for both the 2011 and 2012 projects. If deemed appropriate, these consultants could complete the 2012 surveying and soil analysis during the same mobilization this year. This also provides the City with the advantage of previewing the 2012 reconstruction area for the design of the 2011 project. Since these projects are adjacent, details at the connection points can be analyzed to a greater extent. Current Circumstances The Engineering Department has already begun the preparation of the Feasibility Report for the 2011 and 2012 Improvement Project. The surveying and geotechnical exploration will provide the details necessary to provide a more detailed report. Surveying The City is making a major software conversion in 2010 to Autocad 3D from the previously used Eaglepoint software. Bolton & Menk is already under contract to help the City with the conversion process. Part of the conversion will be helping to set up this project including setting up the CAD layering files and new standards for field symbols. In order to assure that the field data is properly imported and to provide a seamless transition to the new software, the City R\Council\2010 Agenda Reports\07 19 10\11-011 award surveying and soil borings. doc requested a proposal from Bolton & Menk for surveying and base mapping. Bolton & Menk provided a quote in the amount of $29,500 to complete the topographical survey and base mapping. City Staff believes that this price is acceptable based on the unique challenges of this project. The survey cost based on the Bolton & Menk proposal amounts to less than 1 % of the estimated construction cost for the project. Based on industry standards and past City projects preliminary survey work is typically between 1 % and 2% of construction costs. Because these are professional services, additional proposals are not required due to the special nature of professional services provided for in state statute and the City Purchasing Policy. If the City chooses to solicit additional proposals from other companies, the costs could be lower for the preliminary survey and base mapping, but the transition of the data to be used by Bolton & Menk to help the City set up the new software will likely require additional time and expense to convert the data to the appropriate symbols and Autocad 3D layering. City staff believes that it is critical to get this work done as quickly and efficiently as possible to allow for a March bid date. Lost time on the data importing may mean a later bid date and possibly a higher bid. The time expense to convert the data from one company's standard to another's may end up costing the City as much or more than any savings realized by a competitive proposal situation. Staff does not foresee the same issues with construction staking and therefore the City will solicit competitive proposals for that work as part of project construction. Geotechnical Exploration Staff has requested proposals from three firms for geotechnical exploration. They include: American Engineering Testing, Braun Intertec, and Stork Twin City Testing. Each of these firms has previously completed work for the City of Prior Lake. The proposals received are tabulated below: I Stork Twin City Testing Braun Intertec American Engineering Testing Total I $4,949.50 I $10,611.40 $11,655.00 $2,597.00 $4,864.00 $5,870.00 $2,352.50 $5,747.40 $5,785.00 The proposals received were each analyzed and City Staff is recommending that Stork Twin City Testing be selected to perform the 2011 and 2012 geotechnical exploration for the City of Prior Lake. Stork Twin City Testing recently performed the construction testing for City utilities on the 2009 reconstruction project. The pricing proposed by Stork Twin City Testing is similar to the Brooksville Hills geotechnical exploration. Stork was the awarded that work in 2007 for the Brooksville Hills neighborhood and performed well. Staff believes that Stork's familiarity with this work allows them to substantially underbid their competition. Conclusion The City has worked with Bolton & Menk and Stork Twin City Testing on previous projects and is comfortable with the proposals provided. City Staff recommends that Bolton & Menk and Stork Twin City Testing be selected for professional service support for the 2011 and 2012 Reconstruction Project. RICouncil12010 Agenda Reportsl07 19 10111-011 award surveying and soil borings,doc 2 ISSUES: Surveying services for a project of this size are beyond the scope of what the City can provide in house with limited personnel and equipment. The consultant can provide the digital survey in a more expedient manner which in the end allows this project to be bid earlier in the year for possibly a better bid price. The City does not have the expertise or equipment to complete the geotechnical services in-house. FINANCIAL IMPACT: The surveying and geotechnical exploration will be funded through the Construction Fund for these two projects. AL TERNATIVES: The alternatives are as follows: 1. Approve two resolutions (1) Awarding the City's Standardized Contract for Professional Services with Bolton and Menk for 2011 and 2012 Improvement Project Design Survey (2) Awarding the City's Standardized Contract for Professional Services with Stork Twin City Testing for 2011 and 2012 Improvement Project Design Geotechnical Services. 2. Deny this item for a specific reason and provide Staff with direction. 3. Defer this item until a specific date in the future.
