Chadwick Geotechnics Pty Ltd

Business Profile

Chadwick Geotechnics' expertise covers a specialised range of services including ISO/IEC 17025 NATA accreditation for our construction materials laboratory testing for civil, geotechnical & environmental investigations. These expertise are complimented with: * Specialised geotechnical & environmental investigation drilling * Field engineering & geotechnical supervision * Supply, installation and monitoring of geotechnical instrumentation

Products and Services

• Nuclear Density Testing. Our operators provide an integral service to the civil construction and mining industries with quality control nuclear density testing and compaction control during any and all earthworks construction projects, these include; major mining projects, road infrastructure, residential subdivisions, industrial land development projects and rail and water sectors. Our Field staff are well trained in the specifications and technical requirements that, local and state governments, project designers, water authorities and the regional rail network set for construction programs.
• 
• GITA supervision and Testing Services. The role of GITA for a project is to work alongside the construction contractors, observing practices, testing materials and elements of construction and offering feedback/advice to help achieve compliance with the design requirements of a particular project. The GITA is typically engaged by either principle land owner, contractor or consultant to offer independent observation and verification of activities undertaken during construction, but not to act as a project manager directing or controlling work. By specifically offering advice as to whether or not activities are compliant but not taking control of works, we offer benefit of our considerable experience in a variety of construction projects while maintaining our idependence. We believe that this approach gives our clients comfort that we are carefully tracking and testing construction while giving confidence in our assessment, independent of construction contractors. All quality control density testing will be in accordance with: AS1289 Testing of Soil for Engineering Purposes, AS3798 Guidelines on Earthworks for Residential and Commercial Development
• Construction Quality Assurance (CQA) Chadwick Geotechnics (CG) performs as a third party GVC (geosynthetics verification consultant) ensuring that contractors are collecting samples of GM, GCL and GT materials and sending them to independent laboratories for materials testing (as specified by the updated 2010 BPEM requirements for construction of clay liner landfills).
• Telecommunications Investigations Geotechnical investigations for telecommunication cable alignments for Telstra and its sub-contractors since 2003. The purpose of the investigations (referred to internally as rock tests) was to determine the approximate depth and percentage of rock likely to be encountered during the construction (either trenching or directional/horizontal drilling) along a specified length of cable route. The benefits of carrying out these rock tests are to reduce rock claims by contractors, reduce costs of installations of assets, assessments for best for practice methodology (trenching vs boring), reduces downtime during construction and a valuable planning tool for designers.
• Instrumentation Installation and Monitoring
• Chadwick Geotechnics has an experienced team of instrumentation specialists involved in helping customers monitor engineering construction. We have been involved with instrumentation installation and monitoring on many large construction and road projects in Australia and New Zealand Instrumentation Includes: Inclinometers, Pile Testing (Cross Hole Sonic), VW Piezometers, Inclinometer beam sensors and tilt meters, Profilometers, Settlement, Air Quality, Seismic
• 
• Geotechnical Investigations. Our field engineers are available for logging, sampling, supervision and training on a variety of projects including drilling within brown fields projects as well as international geotechnical projects. Our Engineers have extensive experience and knowledge working in Papua New Guinea as Geotechnical Field Managers, providing supervision and guidance to local drilling crews and geologists as well as assisting in the logging of boreholes including SPTs, packer testing and the installation of standpipe Piezometers.
