A Forensic Structural Engineer’s role is to ensure that a building is safe and capable of bearing stresses created by human use, poor workmanship or natural environmental conditions.
A structural engineer can be called to inspect and produce a structural inspection report which shows if there are signs like cracks in the walls, sagging in the ceiling of your property, doors and windows not closing, uneven floors, etc.
The structural engineer can assess the damage, find out the possible cause/s, and suggest remedial measures. Structural Engineers can play a significant role when you are purchasing a property or planning a renovation or extension project.
If you want to know the structural strength or integrity of your building project, a qualified engineer will examine your current structure to ensure if it is safe and as per the Australian regulations and standards.
You can also discuss the structural forensic report cost with the engineer openly. A "Site Inspection" by a forensic structural engineer is $390 + gst ( can differ based on the job’s complexity, scope and distance.
FULL Forensic Structural Engineering Report
The cost of a Full Forensic Structural Engineering Report is different for each project. The following are the rates usually charged:
- Hourly rates for a structural engineer usually begin at around $100, and for complex projects that require a thoroughly professional service, it could increase up to $450 an hour. It is directly proportional to the work involved and the time spent by the engineers. And the cost per hour will also depend on the type of engineer working on your project (Principal Structural Engineer, Senior Structural Engineer, Junior Structural Engineer.
- Prilimenry some plans with no extra research for a few beams, you may be charged around $300. But a detailed report with the engineer’s drawings could cost you around $3000 onwards

- For small buildings – between $300 to $500
- For medium-sized houses – between $500 to $700
- For large buildings or more detailed inspections – between $700 to $1000
For large-scale renovation projects, which need intricate details prepared by an engineer, the costs are:
- Starting from $4500 and upwards relative to the size of the project
- It could be between 5 to 12% of the estimated construction cost
Costs for a contour survey and a soil inspection:
- If it is a basic soil inspection - $350
- If it is both soil and contour survey- $1000 upwards
Which projects can a structural engineer help you with?
These are some of the projects that need a structural engineer:
- Inspection of buildings before purchase
- Constructing an extension
- Conversion of a loft
- Adding a second story
- Damages caused to the structure due to earthquakes or other natural calamities
- Property defect examinations and report
- Installing solar panels
- Removing or modifying internal walls
- Footing design
- Reinforced concrete column design
The benefits of getting your property inspected by a structural engineer
Before buying a property or starting renovation, it would be better if you did a thorough inspection with the help of a skilled structural engineer to verify the property’s strength.
This will help avoid the physical damage and financial losses that could arise if the property structure collapses or gets damaged.
These are the benefits you get from an inspection:
- If you have decided to add certain features like solar installation, an inspection will ensure that your building can take the additional load. Without an inspection, you could be endangering your family’s life along with yourself
- Carrying out an inspection will increase your chances of getting maximum compensation from insurance companies in case anything untoward happens
- If you are removing an internal wall without an inspection, it could weaken the entire building. The structural engineer will help in avoiding such eventualities.
- If you are adding more floors, an inspection will verify if the foundation can take the extra load
- If you disagree with a party over your property, you can hire an engineer for inspection. He can provide an impartial view and prepare an independent report on his findings. He can appear in the court as a witness and present the report on your property.
