Kimley Horn -2- Ardaman 2- Ardaman Proposal No. 25-P-5721 The auger borings will be drilled in the green areas using a hand-held 3 -inch diameter bucket auger. Each sample will be removed from the auger in the field and then examined and visually classified by our crew chief. Representative portions will be sealed and packaged for transportation to our laboratory for further analysis as required. Water level observations will be made in the boreholes during the drilling operation. It is noted that the hand augers may terminate at depths shallower than 6 feet if refusal to penetration and/or borehole collapse during drilling. The asphalt cores will be performed on the shoulders using a portable coring machine equipped with a diamond -tipped core barrel. The locations of the cores will be selected by an Ardaman engineer based on site observations. The thicknesses of the asphalt, base material, and stabilized subgrade (if present) will be measured within the core holes and recorded by our field personnel. Representative samples will be sealed and packaged for transportation to our laboratory for further analysis as required. The core holes will be filled with cold -patch asphalt. We have assumed that one day of Maintenance of Traffic (MOT) will be required for the job. LABORATORY TESTING Routine laboratory visual classification will be performed along with specific classification tests deemed necessary (i.e., percent fines and organic content). We note that no asphalt content testing, extraction/gradation testing or Limerock Bearing Ratio (LBR) tests are being proposed at this time. All laboratory tests will be performed in general accordance with applicable ASTM standards. ENGINEERING ANALYSIS AND REPORT Engineering analysis of all data obtained will be made to evaluate general subsurface conditions and to develop engineering recommendations to guide site preparation within the proposed sidewalk area. We will also provide the pavement core results. Our recommendations, together with data developed during the exploration, will be submitted in a written report upon conclusion of the study. COST ESTIMATE The costs associated with the aforementioned tasks will not exceed below estimates without prior authorization from the client. Subsurface Exploration $5,300.00 Maintenance of Traffic (MOT) — 1 day (@ $2,000.00 $2,000.00 Total $7,300.00 CLOSURE This proposal is subject to the following conditions: (1) access to boring locations is to be readily available to our equipment and field personnel, (2) 1 day of MOT will suffice, (3) the proposed number of borings and the boring depths will be adequate, (4) undisturbed samples and consolidation tests on fine grained soils are not budgeted into the total cost, (5) Ardaman &
