<br /> <br /> <br />-2- <br />December 18, 2002 <br />Task 2 -Perform Both Pavement Reconstruction and Overlay Structural Design Reports <br />NCE will use the FWD data collected on the two streets to develop a pavement design. Deflection data <br />as well as core results and soil testing results will be analyzed for a standard asphaltic concrete <br />reconstruction and overlay design and will be prepared in accordance with AASHTO design <br />procedures. <br />Typical design considerations and issues such as those below will be addressed and included in the <br />designs: <br />• Will base repairs be required? If so, how much? <br />• Milling requirements <br />• Types of asphalt concrete to be used <br />• Use of crack sealants <br />• Use of pavement geotextiles <br />• Recommendations for failed areas (digouts) <br />The recommendations will be summarized in a bound report and submitted to the City for review and <br />comment. Following review of these items by the City, any necessary adjustments will be made and a <br />final report will be submitted to the City. NCE proposes to complete the Draft Pavement Design <br />Report by January 24, 2003 and submit it to the City. After comments have been received back from <br />the City, NCE will complete the Final Report within a week of receiving the comments and deliver to <br />the City for final approval. <br />Total Cost for Task 2: 56,690 <br />The total cost for the two tasks to complete the pavement designs is 511,363. <br />If you have any questions or if there is additional information I need to send to you please call me at <br />(253) 383 - 2322. We at Nichols Consulting Engineers look forward to working with you on this <br />project. <br />Sincerely, <br />~~ € , <br />Paul E.
