SERVICES

Greywacke Geotechnics provides the most cost effective and professional ground engineering services to exceed client's expectations.  From test pits, rock coring and onsite testing to more sophisticated and detailed investigations, our  company offers an integrated ground investigation service providing quality data to the construction industry.

Geotechnical Engineering

 

 

Integration and application of earth sciences into the engineering, design and construction process is vital to every project in the built environment.

Site Investigations

 

Geotechnical Site investigation are carried out to provide comprehensive subsoil data for residential, commercial or infrastructure projects. Site investigations help detemine the existing ground conditions and provide detailed subsoil information on geology, behaviour and  characteristics for civil and structural design.

 

We can provide a geotechnical report as per your council or structural engineers' requirements.

Bearing Capacity Assessment

 

Bearing capacity in geotechnical engineering is ability of the ground to support loads applied from a structure. Allowable bearing capacity is usually mentioned in structural footing drawings to inform contractors' minimum required allowable bearing capacity of the material.

 

We can carry out range of onsite testing to provide bearing capacity of the existing soil. The usual turn around for testing and reporting is 1 to 3 days.

Drilling Services

 

We offer a wide range of geotechnical drilling methods through our inhouse drilling services or professional subcontractors to tackle the various soil conditions throughout New South Wales.

 

Drilling of boreholes, rock coring, installation of water monitoring wells and surface concrete coring are carried in presence of our qualified geotechnical engineers.

Slope and Excavation Stability Assessment

 

This assessment is carried out by our geotechnical engineers in accoradance with Australian Geomechanics Society (2007c) 'Practice Note Guidelines for Landslide Risk Management, Australian Geomechanics, Vol 42, No 1, March  2007 and NSW WorkCover Excavation Work Code of Practice 2015.

 

We can provide professional advise on existing ground stability, excavation stability, battering and benching methods and suitable retaining walls.

Footing Inspection

 

Footing inspection is carried out to determine suitable ground conditions for the provided civil or structural design. This inspection usually carried out by reviewing the geotechnical investigation report/s issued for the site and visually inspecting the exposed ground conditions. However, this inspection may also be carried out in collaboration with onsite testing and laboratory testing depending on the project requirements.

Working Platform Design and Inspection Report

 

 

This report is usually required when a mobile crane or a piling rig is established within a public area or construction site. This report is prepared using available field data, field inspection, onsite testing and laboratory testing of the samples collected from the site.

 

The purpose of this report is to assess the existing ground condtions and provide a safe working area. Depending on the field assessment outcome a working platform design may be required.

Computer Modelling
 
Using our finite element (Numerical Methods) software to analyse deflections/movements associated with deep excavations, construction of shoring walls and slope stability.
