WRECO’s Scope of Work for the proposed Project consisted of the following: Preliminary site visit to mark out the proposed boring locations using a white stake with surveyor flagging (per the USA NORTH mark out guidelines for 50-foot radius coverage) a minimum of 72 hours before the start of the field work. Obtained an encroachment permit from El Dorado County to perform the drilling work within the limits of El Dorado prescriptive easement for the bridge replacement work. Coordinated with the County Staff for traffic interruptions while the drilling work was performed. Drilled two (2) borings, one (1) boring at each of the proposed abutment locations, to completion depths which obtained approximately ten (10) feet of rock core. Backfilled the borings with cement grout per County of El Dorado Division of Environmental Health (DEH) requirements. Performed soil sampling using driven split barrel samplers following the Standard Penetration Test (ASTM D1586) test methods. Tested the soil and rock samples obtained from the borings for grain size determination, plasticity, R-value, corrosive potential, and unconfined compressive strength.
