The <br />results were verified by City-consultant, HR Green. Eight (8) bids were received and ranged between <br />$233,650.00 and $311,242.00. The following is a bid summary: <br /> <br />G Urban Companies $245,076.60 <br />Minnesota Roadways Company $311,242.00* <br />Bituminous Roadways, Inc. $233,650.00 <br />Goodmason Construction. $241,071.70* <br />Pember Construction $257,067.20 <br />North Valley $248,497.13 <br />Omann Contracting Companies $250,492.79 <br />TA Schifsky $244,000.56* <br /> * Adjusted bid total based on corrected math <br /> <br />All but one of the bids were lower than the engineer’s estimate of $271,431.63. The low bid price was 13.9% <br />lower than the engineer’s estimate. <br /> <br />After a thorough review of the bids received, we feel that the engineer’s estimate, along with the low bid, was <br />comparatively accurate, aside from a few bid items. Given the nature of raw materials and labor expenses over <br />the past two years, it was difficult to estimate the construction costs. <br /> <br />The engineer’s estimate was based on previous projects and historical data. Excavation – Common, Bituminous <br />Wearing Course, and Concrete Sill bid items make up the majority of the difference between the engineer’s <br />estimate and Bituminous Roadway’s bid. <br /> <br />Excavation and bituminous material bid items are notoriously difficult to estimate. Excavation cost estimate <br />fluctuate from contractor to contractor because the quantity is generally larger than other quantities and
