Foundation and Footing Inspections
Foundation and footing inspections are crucial components of the construction process, ensuring that the foundation system of a building or structure is correctly installed, stable, and capable of supporting the loads it will bear over time. The goal of these inspections is to verify that the design specifications are met and that the foundation is constructed properly to prevent future issues such as settlement, cracking, or structural failure. Atlas Engineering and Technology Group (AETG) offer foundation and footing inspections, assessments and advice for residential, industrial, infrastructure and commercial construction for compliance and certification of your project.
Services AETG Can Provide
Site Survey: Conduct a geotechnical survey of the site to determine soil type, soil bearing capacity, groundwater levels, and any other relevant site conditions.
Calculate Load-Bearing Requirements: Determine the required size, thickness, and reinforcement specifications for the footing or foundation to ensure even load distribution across the surface, preventing excessive settlement or failure.
Verify Compliance with Design Specifications: Ensure that the foundation and footing design match the approved plans, including dimensions, materials, and reinforcement details.
Check Soil and Site Conditions: Verify that the soil conditions are consistent with the geotechnical requirements and that any necessary site preparation (such as excavation or compaction) is completed correctly.
Monitor Material Quality: Ensure that the materials used for footings, such as concrete and founding material, meet the required standards and specifications.
Prevent Structural Failures: Identify potential issues such as poor compaction, inadequate drainage, or improper installation that could lead to future settlement, cracking, or foundation failure.
Design for Stability: Ensure that the designed foundation or footing effectively prevents excessive settlement or tilting by confirming the ability of the material to uniformly distribute the applied loads.
Benefits of AETG Foundation and Footing Inspections
Foundation inspections and footing inspections are vital to ensuring that the foundation system of a building is constructed correctly and can support the loads placed upon it. Thorough inspections, assessments and testing during the excavation stages to help identify issues early and allow for corrective action before they affect the overall structural integrity. Ensuring compliance with the design specifications and addressing potential problems during construction can prevent costly repairs and enhance the longevity and safety of the structure. AETG's reliable, cost effective and proven methods of assessing foundations and footing stability can help your project by providing adequate advice, remediation methods and design solutions.
Successfully Completed Jobs by AETG to Date
✔ Bearing Capacity Assessment - William Lawson Dr, Prospect NSW
The Bearing Capacity Report by AETG presents a geotechnical evaluation of the soil's bearing capacity for a proposed foundation at William Lawson Drive, Prospect. Three boreholes were drilled to a maximum depth of 4.0 meters, revealing subsurface conditions predominantly composed of sand with variable densities and minor silt layers. Groundwater was encountered at depths of 1.5 to 2.4 meters. The report concludes that the allowable bearing capacity for shallow foundations is 150 kPa under serviceability limit state conditions. It recommends shallow footings be founded at least 500 mm below ground level and provides specific guidance on settlement expectations, site preparation, and construction considerations for optimal structural performance.
✔ Proposed Residential Development - Our Lady Queen of Peace Primary School, Greystanes NSW
The bearing capacity report provides the results of a geotechnical investigation for a proposed residential development. Four test boreholes were drilled to a maximum depth of 3.6 m, revealing subsurface profiles comprising fill, silty clay, silty sand, and weathered rock. The site is suitable for residential footings founded in either medium-dense silty sand or stiff silty clay, with an allowable bearing pressure of 150 kPa, increasing to 350 kPa for deeper weathered rock. Groundwater was encountered at depths between 1.0 m and 2.0 m. Recommendations include site preparation guidance, appropriate footing depths, and considerations for drainage, heave potential, and construction precautions.
✔ Proposed Childcare Development - Richard Road, Leppington NSW
AETG was hired by A&A Building Service to assess the bearing capacity for a proposed slab-on-ground for a Childcare Centre in Leppington, NSW. AETG conducted on-site testing using a Dynamic Cone Penetrometer (DCP) and observed a fill layer approximately 0.5 m thick. The proposed slab-on-ground concrete construction is required to achieve an Allowable Bearing Pressure (ABP) of 150 kPa. Based on the testing data and calculations, the assessment concludes that the founding material meets the required ABP, assuming the fill layer is compacted prior to pouring concrete.
