GGC provides specialised geotechnical engineering services to land development through desktop studies, site investigation, site classification, geotechnical design work, onsite construction support, and earthworks verification and testing.
Our team have extensive knowledge of Perth and Western Australian ground conditions and collaborate with a number of clients requiring tailored geotechnical solutions for conventional and marginal land development projects in the region.
From single lot houses to award winning subdivisions, we have provided cost effective advice, site classification, drainage requirements and testing, factual and interpretive reports, earthworks completion reports, and engineering solutions to a growing number of clients.

Expert Witness & Review
Geotechnical Investigations for site classifcation
Our fundamental belief is that geotechnical investigations should be undertaken to confirm the ground conditions which means that 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 investigations techniques including hand augers, test pits, permeability testing, electric cone penetrometer testing, and boreholes.
From our geotechnical investigations we provide advice on ground conditions and recommendations on how to improve the site to achieve your desired site classification.
EARTHWORKS MONITORING, VERIFiCATION AND TESTING
We provide 'Level 2 Earthworks Supervision' (AS 3798) for Land Development projects. Typically we work with the Earthworks Contractor throughout the construction phase, carrying out site inspections, bulk and civil earthworks verification and testing, providing solutions for the onsite reuse of materials, and sign off the earthworks as completed to a geotechnical standard.
Ground Improvement design, review and verifcation
One of the key ways to manage geotechnical risks is through ground improvement regimes. GGC identifies, designs and verifies a broad range of ground improvement techniques to develop an efficient methodology to remediate a site. By working closely with our civil engineers, we can develop “whole of project” solutions that consider staging of works, materials handling, contractor management and verification.
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 houses, apartments, office-blocks, commercial buildings, machine bases, conveyors, non-process and process mining infrastructure, wharves, jetties and ports, bridges and temporary structures (including mobile crane pads, piling rig platforms, etc).
