Geotechnical Engineering has evolved into a highly-specialized engineering practice as technology has advanced and analytical methods have improved. A thorough understanding of subsurface soil, rock, and ground-water conditions can be essential to the development of a successful project.
Field Exploration Program
The field exploration program is planned and carefully executed to provide information abundantly and quickly. The primary goals of this program are to provide accurate and factual data for an evaluation of subsurface soil, rock, and ground-water conditions. Various field tests include:
- Std Penetration Test (SPT) borings
- rock coring (2-in. & 4-in.)
- surface water barge-mounted borings
- bulk disturbed sampling
ASC's Geotechnical Engineering Group is comprised of serveral highly educated, diversely trained, and experienced individuals providing services in the following areas, including:
- auger borings and hollow-stem auger boings
- piezocone penetration test (PCPT) soundings
- undisturbed sampling
- monitoring wells and environmental sampling
Laboratory Testing Program
Soil and rock specimens collected during the field exploration program are sealed and delivered to ASC's laboratories for testing and a determination of physical, mechanical, and engineering properties. Typical tests include:
- index/mechanical properties for classification
- hydraulic conductivity or permeability
- organic content
- compressibility
- strees-strain characteristics
- corrosion potential
- bearing ratio (LBR, CBR, FBV)
- strength tests
Engineering Analyses and Evaluations
Engineering analyses and evaluation are performed based on several factors, including existing subsurface soil, rock, and ground-water conditions, proposed construction or development information, and structural conditions. These evaluations are founded on experience and sound engineering judgment.
ASC's Geotechnical Engineering Group utilizes state-of the-art software and numerical-analytical tools to solve a variety of engineering problems ranging from capacities for deep foundations to slope stability to settlement estimates.
- site investigations
- shallow foundations
- rock mechanics and rock blasting
- transportation and roadway
- soil and site improvement
- in-situ testing
- geosynthetics design
- site characterization
- deep foundations
- geotechnical instrumentation
- piezocone evaluations
- sinkhole evaluations
Geotechnical Engineering Services are generally performed in 3 inter-related phases.
Geoprobe Model 6625CPT ASC has acquired the Geoprobe Model 6625CPT. The machine is capable of performing Cone Penetration Test (CPT) soundings and is completely operable using remote controls.
