Geotechnical Engineering

Servicing the full spectrum of project sizes across the residential, commercial, government and transport industries, we work seamlessly with our clients and project consultants including architects, structural engineers and builders alike to achieve desired outcomes in a time efficient and cost effective manner.

Having a vast range of experience within the geology and geotechnical engineering sectors both within Sydney and interstate, we are able to provide a wide range of services.

Services

Feasibility Studies

This service supports our clients in identifying the key geotechnical aspects of the project, providing preliminary advice and defining a recommended geotechnical scope of work for design purposes. This may involve a site walkover and/or desktop study using existing knowledge of project area, available topographic and geological information to provide a preliminary understanding of the likely subsurface profile and provide a scope of works investigation and laboratory testing, as required.

Site Investigation

Providing preliminary or detailed geotechnical and hydrogeological investigation of the subject site to assess the subsurface conditions and provide a geotechnical report with site classification, earthworks/excavation, retention, footing, on-grade slab and hydrogeology recommendations for design and/or construction purposes. Precision Engineering Group endeavour to optimise, where possible, timing and budgetary aspects throughout the project cycle at the design stage.
