Residential Geotechnical Reports

LOT CLASSIFICATIONS

Reports in 5-7 days in metro areas – Control your tender process!

The most common geotechnical report requested for residential home construction is what’s referred to as a “Lot Classification” also known as a site classification, site investigation or soil test. It’s a series of tests conducted on a site to classify the soil conditions, enabling the engineer to design the building foundations. If you’re looking to build with a project home builder this is the type of geotechnical report requested by the major home builders. Ideal Geotech are well suited for this market with a large fleet of geotechnical rigs covering NSW, ACT and South East Queensland.

Additionally to a Lot Classification some residential projects will require further investigation/testing depending on the construction, where the site is and if there are any council DA compliance requirements.

LOT CLASSIFICATION

Why do I need a lot classification?

An Ideal lot/site classification report will provide a detailed soil analysis outlining the soil conditions and soil profiles of your site. The report provides the relevant information required for your engineer to design the foundations for your house.

A lot classification is undertaken in accordance with Australian Standards AS 2870-2011 Residential slabs and footings; AS 1726-1993 for Geotechnical Investigations.

Our lot classification for residential construction provides the knowledge for both the engineer and your builder to foresee the challenges and any obstructions they may need to consider in their design on your site. This could include; identifying rock, water table, soft and collapsing soils, tree roots etc.

The report also identifies the wind classification for the site, which is used by both your engineer and the frame & truss manufacturer.

This inexpensive investigation will give you peace of mind and will enable builders to more accuratley determine the foundation costs and managing the risks of getting out of the ground.

WHAT’S IN A LOT CLASSIFICATION?

  • Bore hole drilling identifies:
    • The subsurface soil strata (soil profiles)
    • Moist or hard soils
    • Determines the soil plasticity of clay
      (further laboratory testing maybe required to determine soil reactivity)
    • If fill is present on your site and the depth
    • If a water table is present
    • If there is rock or rock floating boulders on your site
  • DCPs (Dynamic Cone Penetrometer) readings – to determine soil density
  • PP’s (Pocket Penetrometer) readings – bearing capacity of the soil measure in kPa
  • Fall of site – slope measured in degrees
  • Wind classification
  • Soil classification – Determines the soil type A, S, M, H1, H2, E.
  • Site classification – considers other aspects of your site, which may classify your site as a “P”
    See soil facts for detail descriptions of each soil type

TAKE CONTROL BEFORE YOU BUILD

As a home owner looking to build a new home or buying a block of land you will be asked by a builder or your engineer to arrange for a lot classification (residential geotechnical report). Gain the knowledge of what’s below the surface of your building site before you start building. Download the brochure to find out more or order your report today.
