Structural Integrity Assessments

17 July 2025

A structural integrity assessment analyses a structure’s ability to withstand intended loads and environmental conditions. Crucially, a structural integrity assessment doesn’t just examine the structure’s current integrity; it evaluates its expected performance over the course of the structure’s lifespan.

What Are Structural Integrity Assessments?

Structural integrity assessments use a variety of methods to assess a structure’s long-term safety and performance, including:

• Visual inspections
• Radiography, ultrasound and infrared thermography
• Material testing
• Engineering analysis

Typically, all or a combination of these methods are used to assess a structure’s integrity and the results of numerous investigations are compiled to provide an overarching decision on whether a structure is safe, functional and suitable for its intended use. 

Assessment of the Integrity of Structure Containing Defects

Any type of defect has the potential to impact the integrity of a structure, particularly if the defect isn’t identified quickly or if action isn’t taken to repair or mitigate it. 

In some instances, defects can be identified via a visual inspection. However, this may mean that the defect has remained ‘hidden’ for some time before it has become visible, which indicates the need for extensive remedial works. 

Fortunately, you don’t have to wait until you spot visible defects to determine the structural integrity of a building. With accurate defect diagnostic reports undertaken as part of a structural integrity assessment, you can identify hidden defects before they cause additional damage. 

Structural Integrity Assessment Procedure

A structural integrity assessment involves a number of detailed steps, such as:

Planning and Preparation

Before the assessment is conducted, your surveyor will want to gather information about the building, its construction, environment and history. In addition to this, planning will be required to ensure the inspection and assessment can be conducted safely and effectively.

Visual Inspection

A visual inspection is usually the first step to determining whether any defects are present. Your surveyor will look for visible signs of defects in the structure, such as cracked walls, sagging ceilings or water damage.

Non-Destructive Testing

Non-destructive testing allows hidden defects to be identified without causing damage to the structure. Your surveyor may use ultrasonic testing, radiography and/or 3D virtual imaging to conduct these tests.

Materials Testing

In some instances, the materials used to construct the building will be subject to specific testing, such as strength testing or corrosion testing.

Brittle Fracture Testing

A brittle fracture test determines how likely the structure is to sustain a brittle fracture under different loading conditions.

Fatigue Life Assessment

Just because a structure can withstand a specific load once, it doesn’t necessarily mean that it will be capable of withstanding this load numerous times. A fatigue life assessment enables your surveyor to determine how long a structure will be able to withstand such loads before fatigue failure occurs.

Analysis and Reporting

Once the necessary inspections and tests are complete, the results will be analysed in conjunction with one another and the relevant documentation will be drawn up. Specific reports will also be drafted and prepared, so that you can access comprehensive information regarding the results of the structural integrity assessment.

FAQs – Structural Integrity Assessments

When Is a Structural Integrity Assessment Needed?

A structural integrity assessment can be carried out at any time but it’s beneficial to incorporate them into your project from the outset. Even at the planning stage, these types of assessments can be used to determine the safety and efficacy of a proposed design – and can prevent costly remedial works in the future.

Can Structural Integrity Assessments Help Prevent Building Failure?

Yes. These assessments are designed to reveal potential issues with a structure’s integrity and, therefore, its safety. 

What If My Building Fails a Structural Integrity Assessment?

If an assessment shows that the building is unlikely to withstand the intended load, urgent action may need to be taken to ensure the structure is safe. Depending on the reason for the failure, remedial works may be able to resolve defects and restore the structure’s reliability.
