Kimley-Horn - 2 - Ardaman Proposal No. 24-P-5599 rod into the ground and measuring the approximate thicknesses of accumulated soft sediment at the bottom and sides of the canals. We will also install six piezometer wells by inserting slotted 2 -inch diameter PVC well casings within the completed boreholes and backfilling the annulus with soil cuttings. Each well would be installed using a 3 -inch diameter, hand-held bucket auger to a maximum depth of 10 feet below existing ground surface. The locations for the piezometer wells will be selected by the client. Also, the piezometers standing above the existing ground surface will be painted orange or red. The groundwater level will be measured and recorded within the piezometers once per week for a period of 90 days. We recommend that the project surveyor locate our boring/well locations horizontally and vertically (i.e., determine the elevation of the ground surface at the boring locations). This information will increase the accuracy of the data obtained. In addition, six South Florida Water Management District (SFWMD) exfiltration tests will be performed to obtain soil hydraulic conductivity values for others to use in the design of stormwater facilities. The exfiltration test will be performed in accordance with the methods described in the SFWMD Permit Information Manual, Volume IV. LABORATORY TESTING Routine laboratory visual classification will be performed along with specific classification tests deemed necessary (i.e., percent fines). All laboratory tests will be performed in general accordance with applicable ASTM standards. ENGINEERING REPORT Soil stratigraphy and groundwater level data collected during the exploration will be presented in a written report upon completion of the study. We will provide a general discussion of the drainage characteristics of the soils encountered, an estimate of the normal seasonal high groundwater level at the boring/piezometer locations, and the hydraulic conductivity test results at the requested boring locations. COST ESTIMATE The costs associated with the aforementioned tasks will not exceed $20,800.00 without prior authorization from the client. If any piezometers are broken by others (mowers, pedestrians, etc.) during the project time, the client agrees to pay $450.00 per well for the installation of new well. CLOSURE This proposal is subject to the following conditions: (1) access to boring and piezometer locations is to be readily available to our drill rig and field personnel, (2) the provided scope of work will be adequate, (3) no Maintenance -of -Traffic (MOT) will be required, and (4) Ardaman & Associates, Inc. will coordinate the location of underground utility lines through SSOCOF. We cannot take responsibility for damages to private underground lines or structures and/or underground services which do not subscribe to SSOCOF; their locations should be provided by the client prior to commencement of the field work.
