When do you need a Soil Report?
A site classification report, commonly called a soil report, provides the ground information needed for residential slab and footing design. It assesses how the soils may move with changes in moisture and identifies other ground conditions that could affect foundation performance.
The report is generally obtained during the design stage, before the structural engineer finalises the slab and footings. We review the proposed works and available site information to determine the investigation and reporting scope.
New homes and townhouses
Site investigation and classification for new dwellings, dual occupancies and townhouse developments, based on the proposed building locations and site conditions.
Extensions and additions
Assessment for ground-floor extensions and upper-storey additions. Investigation of existing footings may also be required to inform the structural design.
Garages, sheds and other structures
Soil investigations may also be needed for garages, sheds, decks, pools and retaining walls. The assessment is tailored to the proposed structure and its foundation requirements.
ASSESSMENT SCOPE
What we assess
Our investigation considers the proposed development and the ground conditions relevant to foundation design, including:
Investigation methods, depths and any laboratory testing are selected to suit the project and site conditions.
REPORT OUTCOME
Site Classification and foundation recommendations
Yarra Geotechnics prepares a site classification report documenting the investigation findings, borehole logs and relevant test results.
The report provides the site classification in accordance with AS 2870, together with recommendations for suitable founding materials, founding depths and allowable bearing pressures relevant to the proposed works.
These findings give the structural engineer a basis for slab and footing design. Where abnormal ground conditions require particular design measures or further assessment, the report identifies these requirements.
TECHNICAL BASIS
Site classification is undertaken in accordance with AS 2870, Residential slabs and footings, considering soil reactivity and other site conditions that may influence foundation performance.
QUALIFIED PRACTITIONERS
Our reports are prepared and reviewed by appropriately qualified geotechnical engineers, including Chartered Professional Engineers (CPEng) and Registered Professional Engineers of Victoria (RPEV).
VICTORIAN EXPERIENCE
Yarra Geotechnics has experience investigating residential sites across Melbourne and regional Victoria, including reactive clay, sandy soils, filled ground and sloping properties.
