What is a geotechnical causation assessment?

A geotechnical causation assessment investigates the factors contributing to ground movement, structural distress, or foundation performance issues and provides an opinion on the likely causes based on available evidence.

What is soil failure analysis?

Soil failure analysis assesses whether soil conditions such as settlement, uncontrolled fill, moisture changes, erosion, or groundwater may have contributed to structural or geotechnical issues.

When is a geotechnical causation report required?

Geotechnical causation reports are commonly prepared for structural distress investigations, insurance assessments, dispute resolution, redevelopment projects, and situations where the cause of ground movement needs to be understood.

Does a geotechnical causation report determine legal liability?

No. A geotechnical causation report provides an engineering opinion regarding likely causes and contributing factors based on available information. Legal responsibility and liability are determined separately.

What information is included in a geotechnical causation report?

A geotechnical causation report can include site observations, review of available geotechnical and construction information, assessment of soil and groundwater conditions, identified failure mechanisms, causation opinions, and recommendations for further investigation or management.

Does a causation assessment include remediation design?

No. BHM Geotechnical provides investigations and engineering assessments to understand the causes of failure. Detailed remediation or repair design is typically completed separately unless BHM is specifically engaged for that scope.

Assessing the Factors Contributing to Ground and Foundation Failure

Structural distress and ground movement rarely result from a single issue. Ground conditions, moisture changes, drainage problems, construction practices, and site modifications can all influence how the ground performs over time. Understanding the factors contributing to failure is essential when determining appropriate remediation and future risk management measures.

Geotechnical Causation Assessment

A geotechnical causation assessment investigates the circumstances and site conditions that may have contributed to structural distress, ground movement, or foundation failure.

Our investigations may include

Review of available geotechnical, design, and construction information
Site inspection and assessment of visible distress
Assessment of soil conditions, fill materials, and groundwater influences
Evaluation of soil strength, settlement, and foundation performance issues
Assessment of drainage conditions and site modifications
Identification of potential contributing factors and likely failure mechanisms
Development of causation opinions based on available evidence
Practical recommendations for further investigation or management

These investigations help identify the likely causes of geotechnical issues and provide practical information to support remediation, dispute resolution, and future management decisions.

Soil Failure Analysis

Soil failure analysis evaluates the behaviour of the ground and assesses whether soil conditions may have contributed to settlement, instability, or foundation performance issues.

Our investigations may include

Assessment of soil strength, density, and consistency
Identification of soft, loose, or uncontrolled fill
Evaluation of groundwater and moisture influences
Assessment of drainage, erosion, and seepage conditions
Review of soil reactivity and shrink-swell behaviour
Investigation of slope instability, where relevant
Assessment of bearing capacity, settlement, and foundation performance considerations

These assessments help determine whether soil conditions may have contributed to the observed damage and whether further investigation or remediation may be required.

Common Causes of Geotechnical Failure

Ground movement and foundation issues can occur for a wide range of reasons and often involve several contributing factors acting together. Identifying the underlying cause is essential before remediation or repair decisions are made.

Common contributing factors may include

Reactive soil movement and moisture changes
Poor drainage and uncontrolled water ingress
Soft or uncontrolled fill
Foundation movement and settlement
Excavation or removal of support
Tree influences and abnormal moisture conditions
Inadequate site preparation or earthworks
Slope instability and erosion
Groundwater fluctuations
Construction that differs from the original design intent
Historical site contamination or uncontrolled fill, where relevant

Understanding these factors helps determine whether observed damage is likely to continue and what further action may be appropriate.

Geotechnical Causation Assessments for Development, Insurance & Dispute Matters

Situations Where Understanding the Cause of Failure Matters

Understanding the cause of ground movement or structural distress is often essential before repair works, redevelopment, or insurance decisions can proceed.

Our investigations support:

Residential Cracking & Settlement

Investigate the causes of cracking, movement, and foundation performance concerns affecting homes and residential developments.

Retaining Wall & Slope Movement

Assess whether soil conditions, drainage, or instability may have contributed to movement or distress.

Insurance & Damage Assessments

Provide technical information to assist with understanding the likely causes of geotechnical damage.

Construction & Development Disputes

Investigate geotechnical issues where the cause of failure or distress is disputed, and independent technical advice is required.

Infrastructure & Public Assets

Assess factors contributing to ground movement affecting roads, pipelines, footpaths, and other infrastructure.

Redevelopment & Existing Sites

Investigate historical ground conditions and site factors that may influence future development decisions.

What Are the Common Signs of Geotechnical Failure?

Ground-related problems do not always occur suddenly. In many cases, sites exhibit early signs of distress before more significant damage develops. Cracking in walls or slabs, uneven floors, retaining wall movement, localised settlement, recurring drainage issues, and ground movement around structures can all indicate that further investigation may be required.

Identifying these signs early can help property owners, insurers, and project teams better understand potential risks and determine whether a geotechnical causation assessment or soil failure analysis is necessary before issues worsen.
