The corresponding linear <br /> feet of well and casing diameter (s) are provided in parentheses. <br /> Well Perforated intervals bots <br /> LVMD1 80 ' to 102' (22 linear feet of well, 12- and 14- <br /> inch diameter) and 102 ' to 164 ' (62 linear feet, <br /> 12-inch diameter) <br /> LVMD2 80' to 128 ' (48 linear feet of well, 14-inch <br /> diameter) and 128' to 160' (or maximum depth after <br /> well preparation) (approximately 32 linear feet of <br /> well; 12-inch diameter) <br /> LVMD4 0' to 130' (130 linear feet of well, 10-inch <br /> diameter) <br /> LVMD6 40' to 210' (170 linear feet of well, 14-inch <br /> diameter) <br /> The length of well perforation to be paid for by the linear <br /> foot will be the length of the casing being perforated, measured <br /> parallel to the longitudinal axis of the well. This length will be <br /> the payment length regardless of whether the casing being <br /> perforated is single or double. <br /> The contract price paid for well perforation shall include <br /> full compensation for furnishing all labor, materials, tools, <br /> equipment, and incidentals, and for doing all the work involved in <br /> completion of well perforation as described above. <br /> 14-2. 3 SURFACE PREPARATION <br /> A hole shall be excavated around the well casing, and the <br /> casing shall be cut off 5 feet bgs to allow grout to spill over <br /> into the excavation to form a cap. The Contractor may, at his <br /> option, perform the excavation and casing cutting operations after <br /> completion of well grouting. If this option is followed, then grout <br /> level will be held to about 7 feet bgs to allow for the remainder <br /> to be filled and the required cap to be formed. <br /> The contract price paid for surface preparation shall include <br /> full compensation for furnishing all labor, materials, tools, <br /> equipment, and incidentals, and for doing all the work involved in <br /> providing and removing adequate sheeting, shoring, bracing, sloping <br /> or equivalent method for workers' protection, as specified in the <br /> Standard Specifications, these Special Provisions, and as directed <br /> by the Engineer. <br /> 14-2 .4 GROUTING <br /> Each well shall be grout sealed under a pressure of 50 psi and <br /> measured using a pressure gage with a minimum range of 0 to 100 psi <br /> mounted on a temporary well cap at the top of the severed casing. <br /> 6691WEMSECnON.14 <br />
