Conventional Mud Rotary
Cable Tool/Churn Drilling
These methodologies can be applied to Geotechnicall and Hazardous, Toxic and Radioactive Waste(HTRW)) sites, both within, and outside of the Kansas City District (KCD) boundaries.
The KCD Drilling Unit has been involved in innovative applications of these drilling methods for over 40 years and was one of the pioneering organizations in the field of HTRW investigation.
As a result of extensive experience in dam construction and maintenance investigations, the KCD Drilling Unit has developed specialized drilling expertise in dam galleriess and inside buildings. Our crews are well equipped and operate effectively in the harshest weather and ground conditions.
The KCD Drilling Unit has the capability to rapidly mobilize in response to dam safety emergency situations, and has been called upon to do so many times.
The KCD Drilling Unit has broad capability in numerous drilling and sampling methods. We maintain the capability to conduct most routine soil and rock drilling and sampling investigations but our strongest asset is the capability to perform special drilling methods and apply conventional drilling methods to the most unconventional situations. Crews are available for work on Civil, Military, and HTRW (PPE Level-D through Level-B) projects anywhere within the Kansas City District and are also available to provide support to other Districts and government agencies across the country at their request.
Standard mud rotary drilling to depth of 1,500 feet, 2-inch to 13-inch diameters. (Failing 1500)
Rock coring (double tube) in sizes NX, PQ, PQ3 wireline, 4-inch, and 6-inch diameters, plus numerous single tube thin walled diamond core barrels for pavement coring. (Longyear pneumatic, Failing 1500, Diedrich D90 ATV, Diedrich D-90 Truck Mounted, Earthprobe is NX only)
Auger boring: 3.75-inch I.D. hollow-stem auger with 3-inch continuous inner barrel sampler; and 6.25-inch I.D. hollow-stem auger with 6-inch continuous inner barrel sampler. (Diedrich D90 ATV, Diedrich D-90 Truck Mounted)
Standard Penetration Tests, (ASTM-1586-84), large diameter split-spoon drive samples, 5-inch Hvorslev fixed piston thin-wall samplers in mild and stainless steel, 6-inch double tube soil core barrel. (Diedrich D90 ATV, Diedrich D-90 Truck Mounted, Failing 1500, plus specialty equipment)
Cable-tool soil sampling, 4-inch and 6-inch drive barrels (tool steel and stainless steel). This method has also been successfully adapted for use in deep soil gas (to more than 100 feet in depth) investigations. (Buckeye 22-W, and Bucyrus 22-W rigs)
Cone Penetrometer, Mechanical, Electrical, Standard CPT (ASTM D-1586-84) plus HTRW Sensors and direct push Technology
Earthprobe direct push, soil sampling, water sampling, soil vapor sampling, 3-inch diameter auger. (4WD truck mounted)
Gallery, building interior and close space drilling; NX rock core, drive samples, SPT's, and undisturbed sampling. (Longyear, Earthprobe, and specialty equipment)
Most drilling methods can also be performed from barges and floating platforms.
The NWK Drilling Unit crews conduct routine and special investigations on USACE dams within the District. The Unit can also be available for work outside of the NWK District. These investigations include:
The NWK Drilling Unit provides support and conducts routine and emergency inspections for the District's Missouri River Levee System. Responsibilities include:
The NWK Drilling Unit provides support for:
The NWK Drilling Unit provides support for construction projects on Military and other government facilities within the District, including:
The NWK Drilling Unit provides these services to Civil and Military installations, and has extensive experience on DERP and FUDS projects.
The NWK Drilling Unit has conducted HTRW investigations at numerous sites, some of which are listed below:
