With any new home design, GJ Gardner Homes arranges a number of inspections of the proposed building block. The most important being the geotechnical testing of the site, commonly known as a soil test or lot classification
Understanding the subsurface soil layers is key. The investigation is done upfront to give the engineer the required information to design the house slab and footings as well as providing information for the certifier and council. The lot classification may also identify any footing issues and it’s the reason why these inspections are done upfront to remove any potential surprises for the homeowner.
Each site is tested individually as you can’t rely on what’s been built on neighboring properties as a guide or what’s happened during predevelopment of the site. Depending on the field test some building blocks may require soil samples to be taken for further laboratory testing
Mark Eddie from GJ Gardner Homes Newcastle
is currently building homes on a subdivision that had 21 sites tested by Ideal Geotech
. The majority of the building blocks were identified as “M” class sites with some becoming “P” sites due to the depth of fill. One block was identified as a “H1” class with higher reactive soil after laboratory testing was completed. All sites are comfortably handled with the engineer designing the appropriate slab and footings. Over the 21 building blocks the soil condition varies but once construction has been completed each house has been designed and built to suit it’s soil class.
