Sonic Drilling Services for Geotechnical Survey

The contract requires the execution of 14 geotechnical borings using sonic drilling technology to a combined depth of 110 feet, primarily to support a geotechnical survey in a sensitive environmental area. Three of these boreholes are located on or near Grant Lake, necessitating barge-based access due to the inaccessibility of the site by land and the requirement to minimize surface disturbance to preserve the surrounding ecosystem. The work must be completed with precision to avoid ecological impact, emphasizing careful planning and execution under constrained logistical conditions. All drilling activities must adhere to the technical standards associated with sonic drilling, which allows for high-quality soil sampling with reduced vibration and contamination compared to conventional methods. This subcontract, posted on August 7, 2026, is administered by the Fish and Wildlife, Region 6 - Inland Deserts office in California, under NAICS code 213112, which classifies it as support activities for mining. The work site is in an environmentally sensitive region, and while the exact location details such as city or state are not specified, the performance location and regulatory context suggest operations within California’s inland desert region. The subcontract reflects a focused scope with specialized logistical requirements tied to aquatic access and ecological preservation, indicating that the contractor must possess both technical expertise in sonic drilling and experience working in ecologically protected areas with limited ground access.
