We complete Geotechnical investigation for a range of development, including:

multi-level building

basement construction

retaining walls

bridges

distressed building report

slope stability

marine construction

Our geotechnical engineers are experts in Landslide Risk Assessment (LRA). We complete LRA investigation and reports for private and government clients.

We hold Australian Geomechanics Society (AGS) membership and Chartered Professional Engineer status (CPEng), that is a mandatory requirement to perform landslide/landslip assessment for several municipalities including City of Greater Geelong, Colac Otway Shire, Yarra Ranges Council, Northern Grampians Shire, South Gippsland Council, Merri-bek City Council, Frankston City Council and Alpine Resorts Planning Schemes.

Due diligence report is a preliminary geotechnical or/and environmental assessment that provides an analysis of the soil and geological conditions of a potential development site to identify site constraints that can be critical to determine development feasibility. Our services include preliminary environmental (contamination), presence of fill, Land Capability Assessment (LCA) i.e. suitability for wastewater, preliminary landslide mapping, rock depth, groundwater and salinity.

Pavement investigation for new roads and rehabilitation of existing distressed roads is a key area of expertise of St. Quentin Consulting. We have completed pavement investigation and design for various roads across the site, from car parks to major arterial roads. We focus on providing the most cost effective and environmentally sustainable design, often incorporating new technology options, including recycled pavements, foamed bitumen and permeable pavements where suitable.

Our team have specific expertise for geotechnical investigation in the marine environment, including open sea and near shore projects, using specialist drill rigs and barges for various applications, including jetty construction, boat ramp, car park and coastal erosion/stability revetment projects.

A site classification report, commonly known as a ‘soil test’ is a mandatory requirement to inform footing design for residential and commercial construction. Our staff have completed literally thousands of site classification reports over the past 25 years. We commonly provide related services including footing inspections, bearing capacity verification, foundation recommendations, percolation testing for stormwater design and wind rating that ca be performed in conjunction with this service.

St. Quentin Consulting can provide supervision, testing and advice during earthworks. This includes proof roll supervision, for pavements (roads) and bearing capacity verification for structures (including buildings, light and communication towers, wind farms etc) using in-situ field testing, using Dynamic Cone Penetrometer (DCP), Pocket Penetrometer (PP) and Vane Shear apparatus.

We are experts at geotechnical investigation for residential subdivision. Our team can complete detailed investigation for all aspects or urban design, including economical designed pavements, urban storm drainage including detention basin/water investigation, rock and water table proving for underground services.
