GSS Guidance Note covering the application of ACSW data for construction control and validation. Summarises the field outputs provided via GSS C-DAS software and their real-time applications for ground treatment projects.
GSS Guidance Note covering the use of ACSW ground profile data in accordance with CIRIA C703: 2003 Crane Stability on Site - an introductory guide
The guidance note reviews the checks in obtaining ACSW data and the evidence for reliability and repeatably in ACSW ground profiles obtained. It considers some of the factors affecting data quality, limitations on resolution and the impact on any assumed ...
This guidance note summarises the theoretical basis for ACSW profiling and sets out the key considerations the use of ACSW data.
A general introduction to ACSW testing explaining the basis of the test and its application.
This guidance note compares the accuracy of ground stiffness values provided by ACSW testing with commonly used design stiffness values derived from other forms of soil testing such as SPT N value and CPT.
This guidance note reviews the commercially available seismic techniques which can be used to determine ground stiffness and compares each with the ACSW testing technique. The range of seismic techniques has been divided into the intrusive techniques whi ...
ACSW testing is increasingly being used in the railway environment for optimisation of foundations for bridge replacement and electrification schemes. ACSW testing has also been successfully used as a rapid and cost-effective alternative to conventional ...
This guidance note outlines the range of applications for ACSW profile data for cost effective, non-intrusive site investigation and foundation optimisation for bridges.
This Guidance Note outlines a number of approaches for using ACSW testing data to assess rock quality and to derive rock properties.
ACSW testing is principally used to provide representative bulk stiffness profiles for geotechnical design. However ground stiffness can be used to provide an indication of other ground properties and ACSW testing’s non-intrusive nature makes it an attra ...
Published guidance and design codes exists on the application of Vs profile data for seismic and liquefaction assessment. Vs profile data obtained by ACSW testing can provide a rapid and cost-effective means of obtaining representative in-situ Vs profile ...
