What We Do

Geotechnical Reports & Site Classification

Epoch Geotechnical Reports

We provide comprehensive Geotechnical Reports (also known as Geotech Reports or Site Classification Reports) in accordance with Australian Standards to support residential, commercial, and infrastructure developments. Each report is prepared by qualified Geotechnical Engineers with a focus on accuracy, efficiency, and practical recommendations.

A Geotechnical Report provides vital information about the subsurface conditions at a construction site. Our engineers perform thorough site investigations to assess soil strength, composition, and behaviour under load — helping ensure that structures are safe and cost-effective.

Investigations are carried out in accordance with Australian Standard AS 1726-2017 to evaluate the general soil and rock conditions. The results are analysed to determine suitable footing systems, bearing capacities, and Site Classifications in line with AS 2870-2011.

Our reports provide clear, objective recommendations based on engineering principles, including commentary on construction feasibility, material suitability, and long-term ground performance. The aim is to simplify decision-making for engineers, builders, and homeowners alike.

Featured Project

Case Study — New Bunnings Warehouse, Smithfield

Geotechnical investigation Bunnings Warehouse Smithfield

Epoch Services conducted a detailed geotechnical investigation and laboratory analysis for the development of a new Bunnings Warehouse in Smithfield, Sydney. The investigation involved sub-surface drilling, in-situ testing, and laboratory classification of soil and rock samples to determine design parameters for foundations and retaining walls.

Our geotechnical engineers also provided onsite construction support during the building phase, ensuring compliance with engineering specifications and maintaining safe and economical foundation solutions.
