<br />CPH Engineers, Inc. <br />Proposal File No. 06-60-790 <br /> <br />-2- <br /> <br />FIELD EXPLORATION <br /> <br />The field exploration program will include the following: <br /> <br />Description Number of Depth Below Ground <br />Borings Surface (feet) <br />Aeration System 1 SPT 50 <br />Clearwell and Pumps 1 SPT 20 <br />Biofilter 1 SPT 30 <br />Wet Stormwater Pond 1 Auger 20 <br /> <br />The SPT borings will be drilled using a procedure similar to the Standard Penetration Test outlined <br />in ASTM D-1586. The boring will be sampled at 18-inch intervals to 10 feet deep and at 5-foot <br />intervals below 10 feet. The auger borings will be drilled using a 4-inch diameter truck-mounted <br />continuous flight auger. Each sample will be remoVed from the sampler or auger in the field and <br />then examined and visually classified by our crew chief. Representative portions will be seaied and <br />packaged for transportation to our laboratory for further analysis as required. Water level <br />observations will be made in the boreholes during the drilling operation. Cone penetration test <br />(CPT) soundings may be substituted for some of the SPT borings. <br /> <br />LABORATORY PROGRAM <br /> <br />Routine laboratory visual classification will be performed along with specific classification tests <br />deemed necessary (i.e., sieve analysis, Atterberg limits and organic contents). <br /> <br />ENGINEERING ANALYSIS AND REPORT <br /> <br />Engineering analysis of all data obtained will be made to evaluate general subsurface conditions <br />and to develop engineering recommendations to guide site preparation and foundation support. <br />For OUr analysis, we will require specific loading conditions for the structures. <br /> <br />Our recommendations for the structures, together with all data developed during the exploration, <br />will be submitted i1i a written report upon conclusion of the study. <br /> <br />COST ESTIMATE <br /> <br />The costs associated with the aforementioned tasks are estimated as foiiows. The total cost will <br />not be exceeded without prior authorization. <br /> <br />Stake Borings and Coordinate Utility Locations with Sunshine State <br />One-Call by Senior Technician; 3 hours @ $43,35/hour <br /> <br />$130.05 <br /> <br />Mobilize Drilling Crew and Equipment; <br />1 mobilization @ $250.00/mob. <br /> <br />$250.00 <br />
