Geotechnical Drilling Services
Drill Rig Addition | Thoroughbred Engineering is proud to announce an operational investment for improved client services. Having our own drill decreases project schedule and helps reduce the risk to you, the client.
Efficiency | An engineering firm should not be limited to contractual obligation of their firm to the subcontracted drilling company. It simply reduces the engineers efforts to understand the project, and the owner’s risks which, in return may end up costing the client additional efforts and money.
Hiring a geotechnical firm that has its own drill rig can also reduce the speed at which their services are conducted. We are no longer limited to visiting your site by a third party drilling company’s schedule.
Power | Thoroughbred’s geotechnical drill rig was specifically designed for quick and easy exploration of both rock and soil. Our rig is outfitted with two (2) different motors allowing for high torque at low speeds (soil boring), and high speeds at low torque (rock coring). Sampling through soils and into rock is a requirement the geotechnical engineer needs to consider in order to meet the International Building Code (IBC) 2012 requirements, IBC 1803.5.6 Rock Strata.
Accuracy | We outfitted our rig with a hydraulic driven Automatic Hammer allowing for consistent SPT resistant readings, N-Value, over the old wheel and pulley cathead method. Our rigs SPT Auto Hammer includes a 140 pound mass dropping 30 inches in fall. These specifications meet ASTM D1586, Standard Test Method for Standard Penetration Test (SPT).
Size | Our rig has a reduced size, height and smaller foot print allow us to operate in locations others simply can not. We are not limited to low ceilings, or even factories were petroleum engines are not allowed. Our rig also has the ability to even be flown into inaccessible locations by helicopter. Even though our rig stands less than 15 feet tall, it provides the drilling torque needed to auger through the fattest of clays or densest of Kentucky rock and concrete.
