12.0 Borehole Construction <br /> 12.1 Borehole Construction. As discussed in the introduction, the <br /> anticipated subsurface conditions consist of unconsolidated <br /> sediments, including clay, silts, sands, and minor gravels. <br /> The borehole will be constructed using a mud rotary drilling <br /> rig. The mud will consist of Volclay bentonite, or <br /> equivalent. Potable water is available at the Nestle <br /> facility. No other additives will be allowed. The borehole <br /> diameter for the wells shall be of suitable size for the <br /> proposed casing, gravel pack, and grouting operations. The <br /> mud and cuttings from the drilling operation must be contained <br /> in a closed system to prevent spillage onto the ground. At C(Wr� <br /> the conclusion of drilling at each well, the cuttings and mud `'est <br /> must be transported back to the Nestle facility for disposal. <br /> The maximum distance between the facility and the wells is �b e ,� <br /> 1-1/4 miles. ICS Si�Q <br /> Lithologic samples from the cuttings will be collected every <br /> 5-feet during the drilling. It is the responsibility of the <br /> Contractor to provide the necessary access to the cuttings for <br /> the on-site Engineer. The on-site Engineer will be <br /> responsible for the preservation and maintenance of the <br /> samples. <br /> If a hole must be abandoned due to negligence on the Con- <br /> tractor's part precluding use for its intended purpose the <br /> hole will be abandoned and no payment made for said abandoned <br /> holes. <br /> 12.2 Measurement and Payment. Drilling will be paid at the rate <br /> stated in Contractor's proposal, measured from ground surface <br /> to the depth of advancement of the drilling string. The <br /> footage rates shall provide reimbursement for all labor, <br /> materials, bits, fuel, and Contractor's plant required for the <br /> work. No additional payments will be made. <br /> 6 <br /> 1130.3:14 <br />
