Understanding When You Need One and How It Differs From a Building and Pest Report

If you’re buying a property or dealing with signs of structural damage, you may be unsure whether to arrange a building inspection or a structural engineer report. While both are important, they serve different purposes, and knowing the difference can save you time, money, and stress.

This guide explains what a structural engineer report includes, how it differs from a standard Building and Pest Report, and when to call in a structural engineer like Orthos Consulting Engineers.

What’s the Difference Between a Building and Pest Report and a Structural Engineer Report?

When purchasing property in NSW, it’s common to start with a Building and Pest Report conducted by a licensed building inspector. This provides a general overview of the property’s condition, including signs of damage, wear, moisture, or pests.

However, building inspectors are not qualified structural engineers. If they observe something outside their scope, like cracks in foundations or signs of movement, they will often recommend further investigation by a structural engineer.

“Structural cracking noted – recommend structural engineer assessment.”

This is where a Structural Engineer Report comes in.

• • Building and Pest Reports: General condition overview, pest evidence, moisture checks, cosmetic damage

• • Structural Engineer Reports: Specialist diagnosis of structural issues, engineering assessment, and design-level recommendations

Think of the structural report as the next level of investigation when structural concerns are identified.

When Should You Get a Structural Engineer Report?

You may need a structural report in any of the following situations:

After a Building Inspection Flags Concerns

If a pre-purchase Building and Pest Report mentions cracking, wall movement, or structural issues – a structural engineer report provides a qualified opinion on the cause, severity, and required action.

Buying or Selling a Property

Structural reports offer peace of mind during a sale or purchase, especially for older buildings or those with visible cracks or uneven floors.

Renovating or Extending

Before making changes to load-bearing walls or adding new structures, you’ll need a structural assessment to confirm the building can support the works.

Damage After Weather Events

Storm, flood, or earthquake damage may compromise structural safety. Insurance providers or councils often require a structural engineer’s report to support repair claims or approvals.

Visible Structural Movement or Cracking

Cracks in brickwork, sloping floors, or stuck doors and windows may indicate deeper issues. A structural engineer identifies the root cause and outlines your next steps.

What Does a Structural Engineer Report Include?

A typical structural engineer report includes:

• • Site Visit & Visual Inspection: Review of walls, footings, beams, roof frames, and slabs

• • Identification of Defects: Cracks, movement, water damage, corrosion, or uneven settlement

• • Engineering Assessment: Analysis of likely causes, supported by technical knowledge and code references

• • Recommendations: Repair or rectification advice, including design-level solutions if required

• • Photos & Documentation: Clear records of findings to support council, insurance, or legal needs

• • Professional Opinion: Summary of the structure’s condition and suitability for use or renovation
