For builders, designers, developers, councils and rural landowners

Ground, site and land reports, from feature surveys to geotechnical investigations.

Our engineering geologists, engineers and surveyors cover the investigations a project needs before design starts, across Ballarat and regional Victoria.

Geotechnical investigations and engineering geology

Engineering geology gives the insight needed for planning, feasibility, concept design and early risk management, long before detailed design. It identifies geohazards such as landslides, rock falls, sinkholes, flooding and erosion, and guides targeted investigation. Our geotechnical investigations then go well beyond a standard soil test: desktop studies, mapping, drilling, test pits, core logging, in-situ and laboratory testing, and geological models that support design.

Investigations may include

  • Geological, geomorphological and hazard mapping
  • Subsurface drilling and soil and rock logging
  • In-situ testing and soil profiling
  • Sampling and laboratory testing
  • Geophysical investigations
  • Soil and rock design parameters
  • Structural mapping and kinematic analysis
  • Landslip and geohazard assessment
  • Rock fall analysis
  • Geological cross-sections and models
  • Hydrological and groundwater analysis
  • Slope stability analysis

Landslip risk assessments

Landslip risk assessments are a regulatory requirement in many council areas when a planning permit is sought and part of the property is covered by an Erosion Management Overlay. Our chartered engineering geologists assess the likelihood, frequency and consequences of landslides for the proposed development, and recommend how to reduce and manage the risk. Your local council can tell you whether an overlay applies.

Geotechnical assessments for quarries

Proposed quarries, quarry expansions and extractive industry projects in Victoria need an approved work plan under the Mineral Resources (Sustainable Development) Act 1990, and many need a geotechnical assessment to the Earth Resources Regulation guideline for terminal and rehabilitated slopes (September 2020). We provide competent person letters and geotechnical assessment reports that meet the guideline, and they can form part of a ground control management plan.

Land capability assessments

An LCA shows whether a property can treat and manage wastewater on site, with a septic tank or treatment system, without significant environmental or health risk. Most councils require one with the planning or septic permit application for land without mains sewer. We test on site and in the lab, draw the site in CAD and consider every suitable treatment and disposal option, to give your application the best chance at Council.

Usually required when you are

  • Building a new home in an unsewered area
  • Subdividing land where new lots need their own systems
  • Extending a home and adding bedrooms or bathrooms
  • Replacing or upgrading a wastewater system
  • Building a small commercial or industrial facility with toilets

What to send us

  • The property address
  • What you plan to build, including the number of bedrooms, studies and rumpus rooms
  • Any drawings or sketches
  • Any preference for a wastewater system

What you get

  • A scaled site plan drawn in CAD
  • On-site permeability test results
  • A risk and mitigation summary
  • System design information

An LCA does not guarantee approval, but it gives Council the information it needs. We can revise an older LCA if your plans or the standards change.

Site feature plans and bushfire assessments

Site feature plans

A feature and level survey of the site and surrounds, delivered as a CAD drawing or terrain model, using robotic survey equipment. Best done before architectural drawings start. It captures levels and contours, existing structures, neighbouring buildings, trees, drainage, services, driveways and paths, which matters most for economical footing and retaining wall design.

BAL assessments

Required when building or extending in a Designated Bushfire Prone Area. We inspect the site and set the Bushfire Attack Level to AS 3959-2018: BAL 12.5, 19, 29, 40 or FZ. Best done at the same visit as the soil test and survey.

Bushfire management assessments

Required when building or extending in a Bushfire Management Overlay, usually at planning permit stage. Depending on the zone and overlays, this can include a bushfire hazard site assessment, management plan, management statement or landscape assessment. Every report includes CAD drawings with aerial imagery.

Contamination and salinity

Contaminated site assessments

Usually required when subdividing land or changing it to a more sensitive use, such as townhouses on a former house block or a home on a former industrial site. Best done before you buy. The scope depends on the size of the development, the location and the current use. Laboratory analysis is done by a NATA registered laboratory.

Salinity management assessments

May be required at planning permit stage where a Salinity Management Overlay applies. Our geologists and engineers assess how the development may be affected by salinity and how it may affect groundwater and waterways, then recommend rehabilitation and ongoing management in a clear report.

Book site services together and pay less

Soil tests, feature surveys, land capability assessments and bushfire assessments can be done in one visit. Combining them costs less than booking them separately.
