2. GC Structural Engineers Pty Ltd
Website:https://gcstructuralengineers.com/
Address: Stanhill Dr, Surfers Paradise
Contact: 0482 013 534 3.141592
Hours: Monday-Thursday 9:00 AM – 5:00 PM | Friday 9:00 AM – 3:00 PM
GC Structural Engineers Pty Ltd specializes in professional design, detailed technical plans, and full RPEQ certification for residential and civil projects.
Fully accredited and insured, the firm gives property owners total confidence before ground even breaks.
The team notably uses advanced computer analysis and 3D modeling to solve complex structural challenges, producing precise blueprints for everything from home renovations to custom steel sheds.
They also issue both Form 15 design and Form 12 inspection certificates, keeping local building approvals straightforward and compliant.
On the downside, their operational scope is narrow. They work almost exclusively on residential and civil projects, so they are not suitable for large-scale industrial design work.

Mellan Consulting Engineers delivers certified, cost-effective structural solutions designed for safety, efficiency, and full building compliance across the Coast.
Using modern engineering software, they plan smart, budget-friendly structures for diverse projects. These even include swimming pools and retaining walls.
They also offer fast site inspections and emergency structural assessments to evaluate sudden property damage, along with all necessary compliance paperwork.
Their attention to detail stands out, too. We appreciate how they provide reassuringly thorough feedback when reviewing plans for a colleague’s residential patio extension.
Just keep in mind that they focus heavily on regional consulting. They aren’t geared toward handling large-scale international infrastructure design.
Customer Reviews
Able to produce required plans on time
I can confidently say that the service that was provided to me in such a short time frame from James at Mellan Consulting Engineers was most impressive and cost effective. It is rare to get an experienced engineer that is able to produce required plans on time or before time in which Mellan Consulting excelled in. I would highly recommend Mellan Consulting Engineers for your engineer needs, a big 5 star goes out to James.

4. Erwin Structural Engineering
Website:http://www.esedesign.com.au/
Address: 11/39-47 Lawrence Drive, Nerang
Contact: 07 5561 7095
Hours: Monday-Friday 8:30 AM-5:00 PM
Erwin Structural Engineering combines modern software with over 20 years of hands-on experience. With this approach, they create tailored structural plans using industry-standard programs like AutoCAD and Revit.
Their team also designs a wide variety of properties, ranging from single-family houses to multi-residential developments.
A key standout is their specialized knowledge of post-tensioned slab design, where they work directly with contractors on large unit blocks.
On the flip side, their specific focus on medium-sized structures means they aren’t your best bet for a standalone small residential inspection. They generally prefer larger, more involved design projects over simple one-off assessments.
Customer Reviews
Very professional
I have used Richard Erwin for his engineering services for several years now on residential houses and commercial projects. I have always found Richard to be very professional and to have a common sense approach to difficult issues. He also has very reasonable prices compared to other commercial engineers.

5. CSA Engineering
Website:https://www.csaengineering.com.au/
Address: 8/8 Christensen Rd, Stapylton
Contact: 0450 777 081
Hours: Monday-Friday 9:00 AM-5:00 PM
CSA Engineering delivers robust multi-disciplinary structural engineering, building design, and highly specialised industrial certification services. They handle comprehensive residential jobs, tackling tasks like footing design and soil testing.
We noticed that they excel in complex industrial design and certification, specifically working with pressure vessels and process plants. They’re also great at incorporating AI automation solutions directly into their technical operations.
Moreover, they also offer very niche automotive compliance services, including trailer engineering.
The main drawback is their highly specialised industry focus. They mostly support major sectors like mining, automation, and infrastructure, which might feel a bit intimidating if you just need simple home extension advice.
Customer Reviews
Produced excellent work in a timely and cost-effective manner
We engaged CSA Engineering Services to support us in the design of major engineering plant for our projects in the mining sector. The CSA team assigned to our project was highly skilled across all relevant disciplines and produced excellent work in a timely and cost effective manner. We continue to utilise CSA in related projects and highly recommend their services.
