SCOPE OF WORK <br /> We propose to complete shallow cores and FWD testing on each street 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 logging the extent of cracking <br /> and rutting. <br /> • Explore subsurface conditions in the proposed sections by completing from two to six cores <br /> per road section (see below for recommended cores for each road) to depths of up to 5 feet <br /> 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 ESAIs based on traffic data provided by the City of <br /> Eugene. <br /> • Conduct FWD testing at 100- to 1 SO-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 /> Recommended <br /> Road Section Cores <br /> North Bertelsen from Royal Avenue to Roosevelt Boulevard 4 <br /> Seneca Road from West 7th Avenue to West 11th Avenue 3 <br /> North Danebo Avenue from Roosevelt Boulevard to West 11th Avenue 4 <br /> Oakway Road from Cal Young Road to Coburg Road 6 <br /> Chambers Street from Railroad Boulevard to West 7th Avenue 6 <br /> East 23rd Avenue from Patterson Street to Hilyard Street 2 <br /> North Terry Street from Barger Drive to end of street 4 <br /> SCHEDULE AND FEE <br /> We are prepared to complete the field work upon your written authorization to proceed.
