Award Description: The Western Federal Lands Highway Division (WFLHD) of the Federal Highway Administration is preparing to proceed with plans for a geotechnical foundation exploration for three new bridges on the Salmon River, west of North Fork, Idaho.Provide a truck mounted drill rig and all necessary equipment to drill the 15 planned borings. Drill methods required are HQ3 wireline core drilling equipment, 4.25 inch ID hollow stem auger drilling equipment. SK will supply SPT samplers, 2.5 inch, split spoon samplers and all related equipment necessary for drilling and sampling. Drive samples will be taken at 5 foot intervals from ground level until bedrock is encountered. Drill work will consist of 15 borings. These borings are anticipated to be from 20 feet to 40 feet deep. The overburden is anticipated to be 10 to 20 feet in most locations and will be primarily rocky soils with gravels, cobbles and boulders. Once bedrock is encountered the boring will continue until a minimum of 10 feet of bedrock has been recovered. It is critical to this project to determine the bedrock – overburden contact depth. These borings are for the foundation design of 3 new bridges. The drill crew should be prepared to drill to 60 feet if necessary. Traffic control will be necessary for all drill operations. A two person crew is necessary with radios and all personal safety equipment. Flaggers will be certified and carry their certification card with them at all times. Salmon National Forest personnel will have a utility locate done prior to the start of drilling. No drill water will be allowed to enter the Salmon River. The use of silt fences and recirculation methods may be required to contain drill return water.
