This work plan presents the <br />methods and procedures to be used during the construction and destruction of the soil borings for the <br />project. <br />The scope of work includes the construction and destruction of four cone penetration tests (CPTs) soil <br />borings. These CPTs are located within San Joaquin County. The Underground Service Alert (USA) <br />will be notified at least 72 hours in advance of drilling for clearance of underground utilities. <br />METHODS AND PROCEDURES <br />The field work will be conducted by California Push Technologies, Inc. under the direct supervision of a <br />TRC representative. Four soil borings will be performed using CPTs direct push method to a depth of <br />approximately loo feet below grade. The soils encountered in the CPTs will be continuously logged by <br />our representative and described in accordance with the Unified Soil Classification System (ASTM <br />D2488). The approximate locations of the borings are shown on the attached site plan. <br />We anticipate shallow ground water, which will be measured and recorded in the CPTs. Destruction of <br />the CPTs will be performed using neat cement to grout the entire depth. Since ground water is <br />expected to be encountered, destruction will be performed using neat cement with tremie pipe to <br />grout the entire depth of the boring. <br />Page 1 <br />C TRC 313424 <br />
