Advanced Geotechnical Investigation and Geotechnical Testing Services
by Jayden Holden Service ProviderGeotechnical investigation and geotechnical testing
services provide project engineers with the knowledge of ground conditions so
that they can make well-informed decisions regarding the feasibility of a
project. The investigations have acquired substantial importance in preventing
loss of lives and material damage due to foundation cracks, earthquakes, and
other catastrophes. The purpose of the geotechnical investigation is to
investigate the soil and geologic conditions of a property, and to provide
recommendations and design criteria for construction purposes. Geotechnical
testing services can be as simple as conducting a visual assessment of the site
only, or it could be as detailed as a computer-aided study of soil involving
laboratory analysis and testing of the soil and rock conditions and other
parameters.
Geotechnical investigation and geotechnical testing
services are used to ensure that the substructure, which is eventually going to
hold up a structure, is safe and enduring. The below-ground investigation is an
integral part of any construction project wherein the soil strata is sampled
and tested to establish its characteristics, which may have an influence on a
construction project outcome. The serviceability and performance of the
structure depends largely upon the accuracy of the geotechnical investigation
carried out by the geotechnical testing services provider.
Conducting testing and
investigations adhering to international standards
A geotechnical investigation must take place prior to
foundations being laid for any building work. Aussie Hydro-Vac Services
provides geotechnical investigation and geotechnical testing services using
advanced technologies to determine the suitability of the ground for creating
structures. Geotechnical testing services and geotechnical investigations are
carried out by Aussie Hydro-Vac Services in strict adherence to international
standards and guidance in order to provide you with the highest level of field
investigation and sampling, laboratory testing and geotechnical investigation
report data. Expert investigators and testers at Aussie Hydro-Vac Services have
extensive knowledge of topography maps, geology maps, and climate and weather
data, and regional geology conditions of South East Queensland, Brisbane, Gold
Coast, Northern NSW, Western and Central Queensland, and other parts of
Australia.
The following investigations and testing may be done
by technicians and surveyors of Aussie Hydro-Vac Services:
Soil sampling and investigation: The undisturbed samples are taken at certain
intervals to the borehole depth termination and at the change of strata in the
borehole. Disturbed samples can be derived from selected recovered cores of
standard penetration test (SPT). Undisturbed samples using the open tube sample
as thin-walled or thick-walled tube samplers can be applied depending upon the
soil conditions encountered, while undisturbed sampling that uses the piston
sampler can be applied for low-strength fine soils, such as silt and clay.
Standard Penetration Test (SPT): The test is performed in boreholes in order to
estimate relative density and strength-deformation parameters of soils. SPT is
carried out in weak-weathered rocks at certain numbers and intervals to the
borehole depth termination for all boreholes. In addition to soil samples, SPT
can also be used for soil classification purposes.
Rotary core drilling and rock
sampling: A sample of
core/cuttings is collected within a tube with the help of a flushing medium. The
quality of rock recovery achieved is determined by the geotechnical
investigation services team using rock quality designation (RQS), total core
recovery (TQR) and solid core recovery (SCR) ratios that are recorded and
reported for each core run of the geotechnical investigation.
Cone Penetration Test (CPT): CPT is performed by the geotechnical investigation
team to evaluate effectively the site characterization, and assessing
potentially liquefiable materials such as sand and granule gravel, organic soil
and discontinuous lenses.
Geotechnical laboratory testing: This geotechnical investigation is conducted to
determine the specific gravity of the soil solids, determination of the
plasticity index of soils and moisture content of the soil. Engineering properties
tested during a geotechnical investigation by Aussie Hydro-Vac Services may
include a consolidation test to determine the magnitude and rate of
consolidation of soil, and strength and strain-stress relationships of cohesive
soil. Additionally, a rock strength properties test can also be conducted to
classify rock strength and determine the unconfined compressive strength of
intact rock core specimens.
Aussie Hydro-Vac Services provides a variety of
geotechnical investigation and geotechnical testing services to the clients
that include test pitting, tube sampling, auguring, test pitting, geotechnical
investigation of the site, cone penetration testing, and more. Cable location
and pavement investigation services by Aussie Hydro-Vac Services provide
project engineers with reports on pipes and conduits, completed surveys and
leak detection solutions, using the best radar and camera technology.
Non-destructive excavation and
digging services
Other technical services provided by Aussie Hydro-Vac
Services include subsurface engineering and maintenance, CCTV investigation,
surveying services, drone photography services, and more. Aussie Hydro-Vac
Services also provide industrial services for non-destructive digging, vacuum
excavation, and vacuum loading, drain and culvert cleaning, and emergency
response services. The company uses advanced equipment to provide you with
comprehensive reports from geotechnical investigations, geotechnical testing
services, and non-destructive excavation and digging services.
