Structural, Geotechnical and Piling Expert Witness Services

​

Engineering disputes can involve complex technical issues that require specialist knowledge and an independent assessment.

​

JPMANN can provide expert engineering input on matters involving:

• Structural design and engineering issues

• Geotechnical engineering disputes

• Piling and foundation problems

• Foundation design and performance

• Ground conditions and ground investigation

• Structural defects and construction issues

• Settlement and movement

• Subsidence-related engineering matters

• Pile design and installation issues

• Ground improvement and foundation solutions

• Technical investigations and engineering assessments

​

Each case is considered on its individual circumstances, with the relevant technical evidence reviewed before forming an engineering opinion.​

​

Piling and Foundation Expert Witness

Piling and foundation disputes can involve issues such as inadequate design, unexpected ground conditions, pile performance, installation problems or differences between design assumptions and site conditions.

​

Our piling and foundation expertise can be used to investigate technical issues and assess whether the design, ground conditions, construction or installation may have contributed to a problem.

This can include reviewing available design information, drawings, calculations, site information, ground investigation data and other relevant technical documentation.

​

Geotechnical Expert Witness

Ground conditions can have a significant impact on the performance and stability of a building or structure.

​

JPMANN provides geotechnical engineering expertise for matters involving ground conditions, foundations, settlement, soil behaviour and other ground-related engineering issues.

Our assessment can consider available site investigation information, geological and soil conditions, foundation arrangements and the relationship between ground conditions and observed structural problems.

​

Structural Engineering Expert Witness

Structural issues can arise from design decisions, construction methods, alterations, defects, loading conditions or changes to an existing building.

​

Our structural engineering expertise can help assess technical matters involving buildings and structures, including structural defects, movement, cracking, alterations, structural performance and design-related issues.

​

The available engineering evidence is reviewed to establish the relevant technical considerations and provide a clear professional assessment.

​

Expert Reports and Technical Investigations

A clear understanding of the technical evidence is essential when dealing with an engineering dispute.

​​​

Our work can involve reviewing:

• Structural drawings and calculations

• Geotechnical and ground investigation reports

• Piling records and foundation information

• Construction drawings and specifications

• Site photographs and inspection information

• Existing structural conditions

• Relevant engineering documentation

​

Where appropriate, the findings can be presented in a structured engineering report that explains the technical issues, evidence considered and conclusions reached.
