R99-112 ACCEPTING THE BID AND AUTHORIZING A CONTRACT

Home Browse Search

i • � ► The difference between the Engineer's estimate and the low bid was noted by staff. However, the unique type of work involved in this project makes it difficult to estimate. This relates to the contractor's production rate to remove the material, disposal locations and costs, and the corresponding traffic control costs. For this reason, staff does not consider the low bid unacceptable. This work should be done to restore the culvert to its full capacity. It was decided by staff to delay the award until a final determination could be made regarding the source of the sediment as staff suspected that it may have been the result of discharges directly from industries in the area. If an area industry or industries could be determined without question to have contributed to the problem, it was staff's position that an effort should be made for the responsible party(ies) to share in the cleaning cost. Arrangements were made for samples to be obtained and analyzed by a private testing firm. The report findings showed that given the time frame in which sediment had accumulated in the culvert, it would be extremely difficult to trace it to a single source. In addition, the report stated that the material is not hazardous. It was recommended that the material be treated as special waste to minimize the City's exposure to potential landfill contamination issues at some time in the future. Based on the findings and recommendations of the report, staff is at this time ready to proceed with the cleaning of the culvert. Bodine Services has been kept apprised of this project's status throughout the delay in the City making the award of a contract. Bodine is agreeable to performing the work for the original contract amount. Funding for this work will be from the Sewer Fund. It is recommended by staff that the City Council approve the attached resolution awarding a contract to Bodine Services, Inc., for the Jasper Street Box Culvert Cleaning, CP 9740A, as the lowest responsive, responsible bidder in the amount of their bid price of$67,450.00 and that the Mayor be authorized to execute the contract. City staff will be available to answer questions that the Council may have at the meeting. attach: 3 cc: Phillip R. Wilhelm, Municipal Services Manager Thomas N.
