Council Report <br />March 11, 2014 <br />City Project 14 -5, Old Miller Dump Vertical Landfill Gas Vents <br />Page 2 of 2 <br />includes eight vertical vent risers, spaced every fourth vertical vent, to vent vapors to the atmosphere. The <br />remaining twenty -five vertical vents will be completed at grade to allow for relatively easy access for any future <br />maintenance needs or conversion to above ground risers if needed. <br />The bids were higher than the engineer's estimate because it is difficult to evaluate the cost of working in and <br />around a landfill. However, it is our belief that rebidding the project would not result in any project savings. The <br />low bidder Belair Builders, Inc., has done related work with the City in the recent past, and is qualified and <br />capable of performing work of this kind and magnitude. We recommend awarding the contract to Belair Builders, <br />Inc. <br />If awarded, the contract requires project completion by June 1, 2014. However, due to the winter / spring <br />conditions, this project completion date may be extended 60 days. Barr Engineering will provide inspection and <br />monitoring services for this project. <br />Costs and Funding: This project will be funded from the East Side Hazardous Substance Sub - district, Fund 494- <br />41405 -6751. <br />Total Cost Breakdown: <br />Construction Costs $194,313 <br />Contingency (10 %) $19,400 <br />Professional Services $37,000 <br />Total $250,713 <br />rk✓ <br />Grant yffei , P.E. <br />Director of Public Works <br />Enclosure: Bid Tabulation <br />4 Plan Sheets dated 11/26/2013 <br />
