Williams,Jr., City Manager �� <br /> Bruce A. McNabb, P. E.,Director of Public Works � <br /> Stephen P. Swanson,P. E., City Enginee��;�%, <br /> A r/ <br /> SUBJECT: Jasper Street Box Culvert Cleaning <br /> City Project 9740A <br /> The rehabilitation of the Jasper Street sewer from Leafland Avenue southerly to Prairie <br /> Street (refer to attached locale map) is included in this year's capital projects. This sewer is a <br /> combined sewer that carries sanitary and storm flows. In the process of having the interior of the <br /> sewer inspected to determine its condition and needed repairs, it was found that the box culvert <br /> under the Jasper Street subway is filled with sediment and debris. A camera could not be pulled <br /> through this area to complete the inspection of the sewer. The information that was obtained <br /> showed the culvert to be filled with sediment and debris for its full width and to a depth of about <br /> 18 inches. This culvert is 500 feet long, 11.5 feet wide and 30 inches high. It begins about 800 <br /> feet north of Eldorado Street and extends to the north under Jasper Street. The accumulation of <br /> sediment has occurred since the culvert was constructed in 1926, and it is believed that minimal, <br /> if any, maintenance to or cleaning of the culvert has taken place since its construction. <br /> The decision was made that the culvert needed to be cleaned to restore its flow capacity and <br /> to complete its inspection. The Engineering Division prepared the contract documents for the <br /> cleaning of the culvert and the project was advertised for bids. Two bids were received for this <br /> project and were opened on October 13, 1998. The results of the bid opening (a bid tabulation is <br /> attached) are as follows: <br /> Compared to <br /> Engineer's Est. <br />� Bidder Bid Price Over(-Under� <br /> Engineer's Estimate $ 38,000.00 --- <br /> Bodine Services $ 67,450.00 77.50 <br />, Walden Associates, Inc. $ 140,220.00 269.00 <br />
