<br /> { <br /> raveling in the travel sections. There are also instances of isolated fatigue cracking in some <br /> areas. Amore detailed survey of the pavements will assist in completing this evaluation. <br /> SCOPE OF WORK <br /> We propose to complete shallow cores and FWD testing on each road to evaluate the existing <br /> pavement conditions. Our specific scope of services will include the following: <br /> • Complete a distress survey of the existing pavement, including~observing the extent of <br /> cracking and rutting. <br /> • Explore subsurface conditions in the proposed sections by completing 2 to 12 cores per road <br /> section (recommended cores for each road is listed on the attached itemized sheet) to depths <br /> of up to 5 feet below ground surface. <br /> • Maintain a detailed log of the explorations and obtain samples of the pavement, base, and <br /> subgrade materials encountered. <br /> • Provide traffic control and traffic control plans through our subcontractor. We anticipate that <br /> permitting requirements and fees will be handled by City personnel. <br /> • Estimate the traffic loading by calculating ESALs based on traffic data provided by the City. <br /> • ~ Conduct FWD testing at 100- to 150-foot intervals in the outside wheel path of the exterior <br /> lanes in both directions to evaluate the structural condition of the existing pavement and <br /> subgrade modulus. <br /> • Analyze the FWD data to back calculate the in-situ resilient modulus of the subgrade soils <br /> and the effective structural number of the existing pavement structure. <br /> • Evaluate rehabilitation and reconstruction options based on FWD testing, subgrade <br /> conditions, soil borings, and traffic data. <br /> • Provide a report summarizing our recommendations for each road section. <br /> SCHEDULE AND FEE <br /> We are prepared to begin the preparations for field work upon your written authorization to <br /> proceed. Our recommendations will be available 1 to 2 months following the field work. We will <br /> provide a verbal summary of our findings as the information becomes available. <br /> We propose that our services be provided in accordance with the Schedule of Charges, which are <br /> attached to and part of this proposal. For the scope of services described, we will complete our <br /> work on atime-and-expense basis for anot-to-exceed fed of $74,740. An itemization of our <br /> estimated expenditures is included as an attachment. Please note that the above fee is based on <br /> performing testing while minimizing travel between Eugene and Portland, with GeoDesign <br /> personnel staying in the Eugene area when possible. Our budget includes a total of one <br /> mobilization for FWD testing, one mobilization for distress survey, and two mobilizations for <br /> borings. <br /> Services requested and authorized in addition to the preceding scope of work will be provided on <br /> atime-and-expense basis in accordance with our Schedule of Charges. <br /> ~DESIG N= 2 Eugene-7-01:051606 <br /> <br />
