What Is a Bearing Capacity Assessment?

Understanding Ground Strength for Foundation Design

A bearing capacity assessment determines how much load the ground can safely support before excessive settlement or soil failure may occur. The assessment helps engineers, builders, and property owners understand whether standard footings are suitable or whether alternative foundation solutions may be required.

At BHM Geotechnical, we provide practical foundation assessments through:

Dynamic Cone Penetrometer (DCP) testing
Perth Sand Penetrometer (PSP) testing
Soil strength assessment
Foundation capacity evaluation
Geotechnical reporting

These investigations provide information about soil strength, allowable bearing pressures, and site conditions that may influence footing and foundation design.

Our bearing capacity assessment and soil strength testing services support residential, commercial, industrial, and infrastructure projects throughout Adelaide and South Australia.

Soil Strength Testing & Foundation Assessments

Assessing Soil Strength for Footing & Foundation Decisions

Understanding how the ground will behave under structural loads is essential when selecting footing systems and planning construction works. We investigate to assess soil strength, identify weak ground conditions, and provide practical information for foundation design and construction planning.

Dynamic Cone Penetrometer (DCP) Testing

DCP testing is commonly used to assess the consistency and strength of near-surface soils where footing performance, pavement support, or ground improvement requirements need to be understood quickly and economically.

Our investigations may include

In-situ soil strength testing
Ground consistency assessment
Pavement and subgrade assessment
Foundation bearing assessment
Ground improvement considerations

These investigations help identify areas of weak or variable ground and provide information to support soil bearing capacity testing and foundation assessments.

Perth Sand Penetrometer (PSP) Testing

PSP testing is widely used on residential building sites to estimate allowable bearing capacity and provide information for house slab and footing design.

Our investigations may include

Residential foundation assessments
Soil bearing capacity testing
Near-surface ground assessment
Footing design parameters
Ground consistency assessment

These investigations provide practical information for builders, designers, and engineers responsible for footing and slab design.

Bearing Capacity Assessments for Foundation & Construction Projects

Supporting Footing Design, Structural Assessments & Ground Improvement Decisions

Understanding soil strength is essential when selecting footing systems, assessing existing ground conditions, or planning construction on sites with variable or weak soils.

Our bearing capacity assessments support:

New Homes & House Slabs

Determine whether the ground can support standard residential footing systems and identify conditions that may require alternative foundation solutions.

Extensions & Additions

Assess existing ground conditions where additional loads are being introduced to an existing structure.

Retaining Walls & Earth-Retaining Structures

Evaluate soil strength and bearing conditions that may influence retaining wall foundations and stability.

Commercial & Industrial Foundations

Provide foundation information for structures that impose higher loads or are located on variable ground conditions.

Pavements & Hardstand Areas

Assess subgrade strength and ground conditions that may affect pavement performance and long-term durability.

Sites with Fill or Suspected Weak Ground

Investigate uncontrolled fill, soft soils, or variable ground conditions that may increase foundation risk or construction costs.

When Is Soil Strength Testing Required?

Bearing capacity assessments are commonly undertaken where the suitability of the ground for proposed foundations is uncertain or where site conditions may influence footing design and construction costs. Testing is often recommended for sites with variable ground conditions, suspected fill, proposed retaining structures, pavement construction, or developments where additional confidence in foundation performance is required.

These investigations can help determine whether standard footing solutions are likely to be suitable or whether further assessment and alternative foundation measures should be considered.

The Bearing Capacity Assessment Process

A Structured Approach to Understanding Foundation Suitability

Project Review & Site Assessment

We review the proposed development, available site information, and foundation requirements to determine the scope of investigation.

Field Investigation & Soil Strength Testing

DCP testing, PSP testing, and other field investigations are undertaken to assess site-specific ground conditions.

Ground Characterisation

Testing results are interpreted to assess soil strength, ground consistency, and factors influencing bearing capacity.

Bearing Capacity Assessment

Assess testing results to determine allowable bearing pressures and identify conditions that may influence footing design or construction.

Bearing Capacity Report

Provide a detailed report outlining testing results, interpreted ground conditions, estimated bearing capacity, and practical foundation considerations.

Why Bearing Capacity Assessments Are Essential

Why Early Assessment of Soil Strength Matters

A professional bearing capacity assessment provides the information needed to understand whether the ground can safely support the proposed development and whether additional foundation measures may be required.

Determine Foundation Suitability

Assess whether standard footing systems are likely to be appropriate.

Identify Weak Ground Conditions

Recognise soft soils, uncontrolled fill, and variable ground before construction begins.

Support Structural Design

Provide soil strength information to assist with footing and slab design.

Reduce Foundation Uncertainty

Identify potential ground constraints early in the design process.

Avoid Unexpected Ground Improvement Works

Reduce the risk of costly foundation variations and remedial measures.

Improve Construction Planning

Provide practical information that supports efficient project delivery.

FAQs

Frequently Asked Questions

What is a bearing capacity assessment?

A bearing capacity assessment evaluates the ability of the ground to safely support the loads imposed by a proposed structure and provides information used to support footing and foundation design.

What is DCP testing?

Dynamic Cone Penetrometer (DCP) testing measures the resistance of soil to penetration and provides an indication of near-surface soil strength and ground consistency. It is commonly used to assess foundation conditions, identify weak ground, and support footing and pavement design decisions.

What is PSP testing?

Perth Sand Penetrometer (PSP) testing is commonly used on residential sites to estimate allowable bearing capacity and support soil bearing capacity testing for house slab and footing design.

When is a bearing capacity assessment required?

Bearing capacity assessments are commonly required for new homes, extensions, retaining structures, commercial developments, and projects where foundation conditions need to be confirmed before construction.

What information is included in a bearing capacity report?

A bearing capacity report may include testing locations, soil conditions, interpreted ground strength, estimated allowable bearing pressures, and practical foundation considerations relevant to the proposed development.

Does a bearing capacity assessment include footing design?

No. BHM Geotechnical provides the soil strength information used to inform footing design. Structural footing design is typically completed by the structural engineer, footing designer, or builder's design team unless BHM is separately engaged for that scope.
