Rachelle Ravara.jpg


Chartered structural engineer with 14 years’ experience designing new structures, conducting seismic structural assessments and designing strengthening for existing structures. As well as extensive experience in New Zealand, I’ve also worked in Singapore, Hong Kong and the Philippines.

I’m passionate about making the world a safer place to live and believe I can contribute by designing cost-effective, sustainable, buildable and robust structures.


I enjoy working together with architects and other specialists to ensure each structure works with the architecture and solving problems. Every structure is different and so I’m continually learning and developing solutions to new challenges.


You can expect me to keep your project scope and requirements at the forefront of my mind when designing your structure. I am flexible and will provide options if needed, collaborating closely with your project team to ensure your project is delivered on time and within budget. It’s important that you know the status of your project and are aware of any holdups, which is why I provide regular job status updates.

Project highlights include:
  • Bupa Foxbridge Retirement Village and Care Home, Te Rapa. I designed the structures for these 4-storey apartment and 3-storey care facility buildings, which are seismically separated. I worked closely, and built strong relationships, with the client, the architect and the other consultants.


  • 2-16 Wakefield Street, Auckland CBD. This involved a detailed seismic assessment and construction observations required for the strengthening design of this existing 18-storey reinforced concrete building to 100%NBS. I collaborated closely with the contractors and other service providers to ensure that the solutions we provided were buildable and structurally sound. During the construction stage, I quickly resolved issues that were uncovered once the building was opened up.


  • Mason Apartments Stage 2 (Blocks 4 & 5), Otahuhu, Auckland. My tasks involved designing the structures and undertaking construction monitoring for two 4-storey apartment buildings. I worked directly with the client, providing them with options and being flexible. I also provided solutions to issues that arose on site, developing a good working relationship with both the client and contractor.

Senior structural engineer with over 17 years’ experience designing residential, commercial, and innovative structures in New Zealand and China. These include stadia, high-rise towers, low to medium rise apartment blocks, retail and industrial buildings, long-span pedestrian bridges and sculptures. I also have an in-depth knowledge of earthquake engineering.

You can expect me to develop practical structural solutions for your project. I will simplify the design to minimise mistakes, and make it easy to consent, build and maintain. My approach is collaborative – I build strong working relationships with other project parties, sharing ideas and working together to resolve any issues that may arise.


I’ve worked with a range of materials including pre-cast concrete and aluminium, but the materials I most enjoy designing with are structural steel and timber as these materials allow me to develop creative solutions to connect the various elements together.

Project highlights include:
  • Designing an 8-storey volumetric modular apartment in Wellington. This building comprises 80 prefabricated modules stacked “LEGO like’’ on a steel frame podium. This innovative structural system is the first of its kind in highly seismic reactive regions. The system dissipates energy during seismic events without damaging the modules. I standardised all the modules to make fabricating, transporting, and erecting them easy. Due to the limited access for the connections, I developed serval complicated steel connections to ensure structural robustness and quick installation.


  • Designing 36 metre span mass timber beams for Gunyama Park Aquatic and Recreation Centre in Sydney. These are the longest free-spanning mass timber beams in Australasia. Each beam comprises two 1.8m deep glue laminated beams in parallel, connected by one CLT panel to form a composite section. This helps to develop strength and stiffness. To ship the beams, I designed them in 12 metre composite sections. Joints were concealed and were easy for the contractor to construct on site. Each finished beam looks like a single piece of timber.


  • Designing a 10-metre-tall tree sculpture at Auckland Museum. This involved working with both the museum and the artist to bring his vision to life cost-effectively and creating an unconventional shape using conventional timber materials.
