r � � <br />L. Limerock Road Base Material - IRC Bid #3002 <br />The Board reviewed the following memo dated 5/11/93: <br />TO: James E. Chandler, <br />County Administrator <br />FROM: James W. Davis, P.E., <br />Public Works Directo <br />H.T. "Sonny" Dean <br />General Services Di t r <br />SUBJECT: Limerock Road Base Material - IRC Bid # 3002 <br />DATE: May 11, 1993 <br />DESCRIPTION AND CONDITIONS <br />FILE: limerk.agn <br />Last September, the Board awarded Bid No. 3002 to Florida <br />Aggregates for Limerock to be picked up by the County at a cost of <br />$3.75 per ton and to Blackhawk Quarry for Limerock delivered to <br />County at a cost of $6.80/ton. This award is a one year annual <br />occurrence, and will expire September 30, 1993. Florida Aggregates <br />is 44 miles from the Road and Bridge Division. It costs the County <br />$.128 cents /ton/mi le (round trip) to haul limerock. The cost to <br />purchase and haul a ton of limerock round trip from Florida <br />Aggregates to the Road and Bridge Division is: <br />$5.63/ton Hauling <br />3.75/ton Cost of Material <br />$9.38/ton TOTAL COST <br />Stewart Industries submitted a bid to the County at a cost of <br />$3.90/ton. The Stewart Industries mine is only 17 miles from the <br />Road and Bridge Division complex. The cost to haul and purchase a <br />ton of limerock round trip form the Road and Bridge Division is: <br />$2.17/ton Hauling <br />3.90/ton Cost of Material <br />$6.07 ton TOTAL COST <br />At the time the bids were analyzed last September, the Road and <br />Bridge Division used some of Stewart Industries limerock and found <br />that the material contained too much water amounting to <br />approximately 14% by weight (Specs called for 10% water maximum). <br />The staff, therefore, recommended that the bid be awarded to <br />Florida Aggregates. <br />Recently, Stewart Industries indicated that they have solved the <br />water problem and would like to be reconsidered. The County can <br />save $3.31/ton by purchasing from Stewart Industries. Since Road <br />and Bridge will use at least 5000 tons for future projects, savings <br />could be substantial. <br />Also, in Sept. 1992, two companies, Blackhawk Quarries and Stewart <br />Industries, both bid $6.80/ton for limerock delivered. Because of <br />the water problem, the bid was awarded to Blackhawk Quarries. Both <br />Blackhawk Quarry and Stewart Industries agree that it woul& be best <br />for Blackhawk to supply limerock to areas north of SR60 ( since they <br />operate from Palm Bay) and Stewart Industries supply limerock to <br />South County (since they operate from the Indrio Road area in St. <br />Lucie Co.). <br />19 <br />MAY 18 1993 BOOK 89 FADE 559 <br />
