CASE <br /> <br />CONSIDER CHANGE ORDER FOR ELMCREST PARK PARKING LOT <br />IMPROVEMENTS <br /> By: Leonard Lint0n, Civil Engineer II <br /> <br />Background: <br /> <br />Elmcrest Park parking lot improvernents were approved for construction on July 20041 Soil borings <br />indicated that clay soils were present under most of the parking areas. Borings were not per£ormed <br />for all of the trail areas. The pavement design included geotextile £abric and sand under the Class 5 <br />aggregate due to the presence of the clay. The sand was also specified to be placed under ail trails. <br />Areas of sand were found during the excavation of the site and the extent o£ the geotextile fabric <br />was reduced per the recommendation of the geotechnical testing firm. Grading for the trails has <br />encountered extensive areas of sandy soils that will not require additional sand fill. The project <br />design anticipated sand would be available from the excavation of both ponds on the eastern side o£ <br />the site, thus the quantity of sand to be imported was reduced. The soils in the easternmost pond <br />turned out to be clay down to the excavated depth. These soils were Used as fill below the <br />geotextile fabric, requiring import of additional sand. <br /> <br />The lack of sand in the eastermnost pond-required the import of additional sand to complete the <br />project. The presence of sand'under the trails will reduce the required quantity of imported sand. <br />The impacts of these changes are sunwnarized below: <br /> <br />[Area <br /> <br /> P arkin g Lots <br /> Trails <br />_Net Change <br /> <br />Cost <br />$ 27,300 <br />$ (69,164) <br />$ (41,934) <br /> <br />These numbers reflect the changes in the quantity of sand used on this project. The cost savings due <br />to the reduced quantity of geotextile fabric used are not included in this tabulation. <br /> <br />Staff is working with the contractor to finalize the amount of the change order. This amount will be <br />presented at the meeting for evaluation. <br /> <br />Action: <br /> <br />Staff recommends that the Committee fo~wvard the request for Change order # 1 for Ehncrest Park <br />improvements to City Council for approval. <br /> <br />Reviewed by: <br /> <br />Director of Public Works <br />Assistant Public Works Director <br />Parks/Utilities Supervisor <br /> <br />PW: 10/1.9/04 <br /> <br /> <br />
