Seward Meintsma > <br /> September 1, 2004 ; <br /> <br /> ' Page 3 <br /> Pavement Analysis & Report <br /> The FWD and core test data will be analyzed to backcalculate the in situ Mr of the subgrade soil and, <br /> for overlay or inlay analysis, the effective structural number of the existing pavement. Truck and bus <br /> traffic data provided by the City will be analyzed to develop estimates of the cumulative equivalent <br /> 18,000-pound single axle load (ESAL) repetitions fora 20-year design period. Pavement design <br /> analysis will be accomplished using the procedures of the January 2003 ODOT Pavement Design Guide <br /> and the 1993 AASHTO Guide for Design of Pavement Structures. Design recommendations will be <br /> developed for overlay, inlay, deep milling and reconstruction as appropriate for the project conditions. <br /> Alternative flexible and rigid pavement designs will be developed for reconstruction. We will prepare <br /> technical memorandum reports for each roadway segment to present our findings and <br /> recommendations. These reports will include design documentation, distress maps and typical sections <br /> depicting our design recommendations. <br /> Field Review Meeting <br /> We have assumed one meeting with City staff for field review of the projects. <br /> Project Schedule <br /> Our estimated schedule for the work is as follows: <br /> Project Schedule -Table 2 <br /> Task Start Date Estimated Com letion Date <br /> Project Start October 4 <br /> Field Reconnaissance October 4 October 8 <br /> FWD Testin October 11 October 15 <br /> Visual 5urve October 11 October 22 <br /> Corin Ex lorations October 25 October 29 <br /> Desi Anal sis November 1 November 24 <br /> Re rts November 22 December 10 <br /> Project Fee <br /> We propose to accomplish the above described work scope on a time and expenses basis in accordance <br /> with the rate schedule in our current Personal Services Contract with the City (2003-00216). Our <br /> estimated fee as itemized in Table 3 for this work is $64,800, which we agree not exceed without your <br /> prior authorization. In case it becomes necessary to adjust the scope of projects included in this <br /> proposal, the not to exceed fee can be adjusted accordingly at the unit rate of $2.27 per centerline foot <br /> of street for increases or decreases in project scope within t 30% of the total length of the street <br /> segments now included in the proposal (28,708 lineal ft). <br /> <br />
