Shaft investigation and design

A full range of shaft site investigation field services, including engagement of drilling contractors, drilling supervision, core logging, boxing and sample selection, geophysical investigations and packer testing.

The interpretation of the geotechnical and hydrogeological assessments yields information for shaft excavation method selection and design of shaft collars, pre-sink, foundations and liners.

Our team can conduct post construction monitoring, design of instrumentation and monitoring systems and data collection and interpretation. Our approach includes the development of a ground model at the site of the proposed shaft. This includes rock mass characterisation, hydrogeological assessment, structural interpretation, kinematic and stress analysis.

A comprehensive range of development planning, site selection, scoping studies including shaft excavation options, site investigations planning.

Our shaft engineering team has worked for both mine owners and shaft excavation contractors. Our on-ground experience in the excavation phase of shaft projects has enabled us to refine our shaft assessment and design capabilities. Our construction phase services include project and risk management, certification of structures, geotechnical mapping, assessment and ground support recommendations, design verification, QA/QC monitoring and testing and peer review.
