We guarantee superior expertise and customer service when you work with RBC.
3. How long does a typical pre purchase structural inspection take?
We recommend to our Clients to opt for a pre-purchase structural inspection in conjunction with a timber pest inspection for complete peace of mind. This structural inspection takes approximately 1.5 hours to complete. Larger homes may require additional time on site.
4. Can you provide structural engineering advice regarding the removal of load bearing walls?
We certainly can provide advice on the removal of load bearing walls in Perth. The best approach is to undertake a structural inspection of the building to determine the options to re-distribute the load path. If you arrange a pre-purchase structural inspection or a pre-purchase building and pest inspection in the Perth Metro area, can can provide advice regarding removal of walls as part of our service for a small additional fee. Obtaining the original architectural and structural drawings will be of significant benefit and result in lower cost for producing the structural engineering documentation.
5. What is a retrospective building approval?
A Building Approval Certificate can be applied for to retrospectively approve of an unauthorised structure or work after the building is completed. This includes minor structures such as patios, sheds, fences, retaining walls, swimming pools and spas. In most cases a structural engineer is required to provide the engineering certification and a building surveyor is also required to provide the certificate of construction compliance.
6. How can RBC assist with a retrospective Council approval for my patio, shed, carport, retaining wall, brick fence or similar structure?
Generally, in order to obtain a retrospective Building Approval Certificate, the Client will need to engage a Building Surveyor to issue a Certificate of Building Compliance. This document requires certified engineering documentation that RBC can provide. We can also recommend and work with our associate Building Surveyor to speed up the submission of documentation. In most cases, a structural inspection is required to verify the structural condition of the structure. In some situations, modifications may be required subject to our site inspection in order for the structure to achieve structural sufficiency. It is important to note that a pre purchase building and pest inspection in Perth will not always identify unauthorized structures.
If the Council confirms that the unauthorised structures does not require planning approval the retrospective approval can be obtained using the following 3 steps:
Step 1 – Engage a Perth structural engineer such as Rotaru Building Consultants to undertake a structural inspection and provide structural engineering certification usually in the form of a report;
Step 2 - Engage a Registered Building Surveyor to confirm documentation and technical certificates that may be required but usually a BA18 Certificate of Construction Compliance will be applicable in most cases;
Step 3 - Submit all the above documents to the relevant Council or Shire for assessment.
In most cases if the above steps are followed, a retrospective approval for unauthorised building work and/or structures can be obtained. However, if the unauthorised building / structure does not meet the performance requirements of the Building Code of Australia or relevant Australian Standards, you may be required to remove the structure.
Our team can assist with the retrospective approval process described above. In most cases the best approach is to conduct a structural inspection on site which will enable us to provide engineering certification for the existing structure or building.
Contact Rotaru Building Consultants Perth to discuss your specific requirements and to obtain a quote for structural inspection certification.
7. What are the requirements to produce retaining wall engineering drawings or certified details?
It is recommended that specific information is obtained form your local Council. Generally, a site plan will be required showing the location of the retaining wall(s) in relation to the property boundaries and existing buildings on the property. We can assist with the architectural elevation and plan view drawings as well as the structural engineering details suitable for the building permit application. In most cases, structural engineering certification in Perth for a limestone retaining wall, panel and post retaining wall, Besser blocks or concrete masonry retaining wall, brick cavity filled retaining wall or concrete reinforced retaining walls can be provided within 48 hours. It is standard procedure for us to assess the location of the main sewer line and ascertain if the proposed retaining wall requires additional measures in accordance with the Water Corporation Protection of Assets requirements.
8. How can I verify that the structural engineer is qualified and registered?
The National Engineering Register (NER) has been created by Engineers Australia to provide a means of presenting registered engineers and their services to the public. It also provides assurance to consumers that engineers engaged from the NER meet the high standards of professionalism expected in the engineering profession. The NER is available to allow consumers to search for a qualified engineering practitioner by name, area of practice and geographic location.

More than just a pre purchase building inspection report for Perth Homebuyers
Buying a home or an investment property in Perth is a major financial undertaking and it is recommended that a pre purchase structural and timber pest inspection is undertaken before signing the Offer and Acceptance contract for the purchase. This important decision should be supported by knowledge of the physical state of the property so that you can avoid substantial hidden costs. There are calls in the WA industry to introduce compulsory building inspections during construction to endure the quality of homes. Until then, obtaining a pre purchase building inspection Perth report will enable the buyer to make a better informed decision as to whether to proceed with the purchase. Is a pre purchase structural inspection report compulsory in Perth? The answer is no. Current legislation in Australia does not include a provision for home buyers to obtain a building and pest inspection report.
The pre-purchase building and pest inspection and reporting is to be undertaken by a qualified inspector with appropriate professional indemnity insurance. It is essential that the inspector engaged can provide independent and objective advice to the buyer with no bias or conflict of interest. Our structural engineering building condition inspections, assessments of existing buildings and pre-purchase building inspections are conducted by our licensed professional structural engineers to ensure their structural integrity has not been compromised. If the property contains a swimming pool or deck area for example, it is important to arrange for a pre purchase building and pest inspection combined with a pool inspection or deck inspection to allow our engineer sufficient time to inspect all aspects. Note: Any pool owner has a legal obligation to ensure that effective operation of the swimming pool and spa safety barriers is maintained. Gates are to remain closed at all times except when accessing the swimming pool.
Pre purchase building inspection Perth
To conduct a pre purchase structural building inspection of an existing home in Perth, one of our structural engineers will visit the building and carry out, with due diligence, the following:
-
a visual inspection to identify types of structural defects and evidence of material deterioration;
-
items that may require maintenance to avoid structural defects or loss of utility;
-
additions, extensions or other structures that appear to be unauthorised; and
-
non-structural components that might affect structural systems.
If signs of structural deterioration or defects are identified, our structural engineers provide opinions on the severity of the deterioration or defects and recommend appropriate actions to be taken. This might involve repair works or further structural investigation to parts of building. If there are signs of structural inadequacy and their causes are not apparent, a structural analyses should be performed to determine if the original structural design was adequate.
A qualified structural engineer will quantify observed structural deterioration or defects and analyse their potential impact on structures, as well as provide advice on the potential impacts of the deterioration or defects.
A typical pre purchase home inspection will result is a detailed inspection report which will include a specific observations, safety concerns and may contain advice on remedial work.
