The borings will be made by a truck-mounted drill rig using mud rotary / hollow-stem auger drilling techniques. A detailed geologic reconnaissance of the vicinity of the pedestrian overlook will be completed along with the locations of the planned borings. Two to three borings to a depth of 20 to 25 feet are proposed in the street and/or shoulders. Disturbed standard split-spoon samples will be obtained from the borings at about 2.5-foot intervals of depths to a depth of 20 feet and at 5 feet intervals thereafter. The Standard Penetration Test will be conducted while the disturbed split-spoon samples are being taken. Thin walled Shelby tube samples will be collected as appropriate. The borings will be subcontracted to a drilling contractor experienced in drilling and sampling soils for engineering purposes. The drilling and sampling will be accomplished under the direction of an experienced geotechnical engineer or engineering geologist from Rhino One, who will locate the general areas for drilling, contact private utility locates prior to drilling, and maintain a detailed log of the materials and conditions uncovered during the course of the work. Laboratory testing will include standard classification tests, such as natural water content,...
