Top Rated Structural Engineering Company in Gold Coast
EXCELLENT Based on 43 reviews Posted on Ben Burleigh2025-11-01Trustindex verifies that the original source of the review is Google. Tayfe and Sam have been great to deal with since we engaged them for a retaining wall we needed to build. Their communication and availability has been exceptional and we will definitely be using them again in the future. Highly recommend!Posted on Aiza Qen De Monteverde2025-09-29Trustindex verifies that the original source of the review is Google. Great communication and received the report in a timely manner.Posted on Mark Pracy2025-09-26Trustindex verifies that the original source of the review is Google. I chose Rainbow Engineering based on their strong Google reviews. I requested a quote for the retrospective structural certification of a detached non-habitable dwelling and proposed an inspection before committing to the full $4,000 fee. I agreed to and promptly paid the $550 (incl. GST) site visit fee, expecting it to include guidance on a solution and path forward. I was told I wouldn’t receive a formal engineering report but would get technical guidance. During the inspection, Tayfe pointed out obvious compliance issues, which I didn’t dispute. However, after the visit, I received no actionable guidance—only an accusation that the space was being used as a Class 1 habitable room instead of the approved Class 10, followed by a list of non-conformances. I had to remind them that the purpose of the inspection was to provide technical guidance. I also challenged what I believed was an incorrect reference to the Australian Standards regarding vapour barriers, but this was dismissed without discussion. Eventually, I received a list of issues that made the certification process seem unfeasible. While Rainbow Engineering may be suitable for design work, I would not recommend them for retrospective certification. I can’t speak to their other services, which may be excellent—I just wanted to share my experience, as I rely heavily on Google reviews when choosing service providers.Posted on Peter2025-09-25Trustindex verifies that the original source of the review is Google. Rainbow Engineering has been incredible to work with from start to finish. Tayfe and Sam were prompt, professional and exceeded all of our expectations working on a very complex engineering project. Without a doubt the best in the structural engineering business, you are in safe hands with Rainbow Engineering. Thanks again Tayfe and Sam.Posted on Donna Reynolds2025-09-10Trustindex verifies that the original source of the review is Google. ✨ Reference – Rainbow Engineering To Whom It May Concern, I am writing to provide my highest recommendation for Rainbow Engineering. I engaged Rainbow Engineering to provide an independent engineering assessment in relation to a complex insurance dispute concerning storm damage to my rural property. From the outset, their professionalism, expertise, and integrity stood out. Key strengths I observed: Technical expertise: Their engineer Tayfe, applied rigorous methodology, explained findings in clear and accurate terms, and used proper engineering language while also making the conclusions accessible for non-technical audiences. Independence & integrity: Rainbow Engineering approached the matter impartially and without bias, ensuring their report was based solely on the evidence. This was particularly important given the dispute context. Attention to detail: The report addressed every relevant factor thoroughly, highlighting the principal cause of damage and clearly distinguishing between insured storm damage and unrelated issues. Communication: They were responsive, patient in answering my questions, and committed to ensuring I understood the process and findings. Professional standing: Their work complied with regulatory standards (including RPEQ requirements), giving the report authority and credibility in legal and dispute resolution settings. The quality of Rainbow Engineering’s work has given me confidence and clarity in navigating a highly technical and stressful situation. I believe their services would be of great value to anyone requiring independent, reliable, and professional engineering expertise. I recommend Rainbow Engineering without reservation. Kind regards, Donna ReynoldsPosted on Matthew2025-09-05Trustindex verifies that the original source of the review is Google. I am buying a house and needed the driveway inspected. Rainbow Engineering did the inspection quickly with a good price and gave me the all clear. Thanks Tayfe and the team.Posted on Deanne Thompson2025-08-31Trustindex verifies that the original source of the review is Google. Rainbow Engineering have been absolutely fantastic to deal with. We called them initially to inspect some cracks in the chassis/drawbar in our almost brand new caravan (only 9 months old). Their inspection was carried out with great care and attention to detail, they not only inspected the cracks but the entire chassis. The report we received was thorough, clear, and easy to understand. We are so grateful for their honesty, transparency, and professionalism. Rainbow Engineering made a stressful situation so much easier, and we wouldn’t hesitate to recommend them to anyone needing independent, reliable engineering advice.Posted on Robert Kinnaird2025-07-22Trustindex verifies that the original source of the review is Google. We cannot speak highly enough of Rainbow Engineering Services and their exceptional team, Tayfe and Sam. Their professionalism, expertise, and unwavering dedication were absolutely crucial in helping us win our insurance claim through AFCA, after our insurer wrongly attempted to deny it—claiming the damage to our fence was due to “wear and tear” rather than the severe storm we experienced on Christmas Day 2023. Tayfe and Sam are extraordinarily knowledgeable. Their detailed assessment, comprehensive reports, and clear, confident explanations left no doubt that the storm was the true cause of the damage. Thanks entirely to their skill and commitment, we successfully overturned the insurer’s decision. Without their support, we simply would not have won a case that never should have been disputed in the first place. They went above and beyond at every stage—showing genuine care and taking the time to ensure we fully understood the process. We are deeply grateful. We would turn to Rainbow Engineering Services again in a heartbeat, and we recommend them without hesitation to anyone needing expert, trustworthy support. Thank you, Tayfe and Sam — you truly made all the difference.Posted on Sanctuary Palms2025-07-14Trustindex verifies that the original source of the review is Google. Rainbow Engineering - a pleasure to deal with. They explained issues in a language we could understand and sent through a comprehensive report. We can confidently recommend Tayfe and Sam .Posted on Gin Clare2025-06-30Trustindex verifies that the original source of the review is Google.
