Mining and Non-Process Infrastructure
Providing our geotechnical expertise to mining infrastructure and NPI projects is a major part of our business and we have built a reputation on quick turnarounds and client focused advice.
Each mining project is different and each site requires a full understanding of both its geotechnical and practical requirements. We work with an increasing number of clients, at various stages from PFS to construction, to maximise efficiency in planning and construction in relation to ground conditions, borrow materials, foundation and slope design, and construction monitoring.
We are involved in a broad range of projects from ports and rail in West Africa to leach floatation tanks in New South Wales. Whether scoping a new mining project or onsite construction monitoring, GGC provide timely and robust advice, information, and recommendations to suit every type of site.

Expert Witness & Review
Our fundamental belief is that geotechnical investigations should be undertaken to confirm the ground conditions and materials properties and behaviour, and as such we undertake investigations to target particular and project specific issues. This pragmatic approach provides value for our clients and a more robust application of geotechnical engineering. We utilise a variety of investigation techniques including hand augers, test pits, permeability testing, electric cone penetrometer testing, and boreholes.
From our geotechnical investigations we provide factual and interpretive reports to present and findings and recommendations based on the ground conditions and the proposed development.
ONSITE CONSTRUCTION SUPPORT AND TESTING
We are frequently involved in providing onsite construction support for mining infrastructure projects. Typically, we work with the Contractors throughout the construction phase, carrying out site inspections, bulk and civil earthworks verification and testing, recommending solutions for the onsite reuse of materials, and sign off on the completion of earthworks to a geotechnical standard. We undertake footing excavation inspections, cut slope inspections, sample borrow materials, provide supervision of method specification development, and provide solutions for unforeseen ground conditions.
We also provide to the project owner (Principal), earthworks and design verfication services during the construction phase of a project.
GROUND IMPROVEMENT DESIGN, REVIEW AND VERIFICATION
One of the key ways to manage geotechnical risks is through ground improvement regimes. We identify, design, and verify a broad range of ground improvement techniques to develop an efficient methodology to improve foundation conditions. This could include ground stabilisation through the use of geotextiles, cement products, or remove and replace techniques.
FOUNDATION DESIGN AND VERIFICATION
The analysis, specification and verification of cost-effective and technically efficient foundation solutions requires a detailed understanding of the subsurface soil, rock and groundwater conditions and knowledge of soil mechanics and engineering geology principles. Our expertise can help you to optimise the foundation solutions for your project and the site-specific conditions. We can provide foundation recommendations and design input for all stages of your project and for all foundation types supporting conveyors, non-process and process mining infrastructure, wharves, jetties and ports, bridges and temporary structures (including mobile crane pads, piling rig platforms, etc).
TENDER DESIGN AND OPTIMISATION
GGC seeks to reduce geotechnical risk, design conservatism and construction costs by providing realistic and pragmatic options for our clients. GGC has a team of geotechnical engineers and engineering geologist experienced in assisting clients during the tender design process, or for design and construct projects. Our team review all available geotechnical reports, specifications, drawings, loading data etc, and create geotechnical models for the project to identify project risks and opportunities.
The breadth of our services through the tender design phase include quarry assessments, borrow material assessments, cut slope design and earthworks materials through to retaining wall design, ground improvement design and foundation design.
SLOPE STABILITY ANALYSIS AND DESIGN
GGC uses our experience to develop a geological model and identify the likely slope stability mechanism. We have the technical capability to undertake numerical analysis to assess the likely Factors of Safety against instability as well as identifying appropriate risk mitigation issues to address the appropriate mechanism. Our team also have the skillset to undertake the specification, construction support and verification of the slope protection system.
