Thomas Zhang

Thomas has recently become a Chartered member of Engineering New Zealand and Chartered Professional Engineer. CPEng is only open to professional engineers, who demonstrate an ability to deal with complex engineering problems and activities and provide evidence of New Zealand-specific good practice.
Thomas has been involved in many projects with Structus, as a senior member of the Structus team. Some of his most memorable have been Aria Bay, Te Kotuku and De La Salle College all of which involved many engineering challenges. Thomas has been enjoying the engineering challenge of mass timber buildings recently, designing 4 no. for an Aged Care provider throughout the North Island.

Aria Bay – Stage 2

Aria Bay – Stage 2
Progress as we lift to Level 1
Aria Bay is a retirement village located in Browns Bay, Auckland. It is exciting to see Level 1 taking form during our recent construction monitoring visit to site. Level 1 is part of the two 5-storey apartment blocks and link structures that form the last stage of this development, following completion of the Care Wings in 2020. The existing structures on site will be connected to the new facility through complex elevated link structures over several levels.
Structus are pleased to be continuing to work with Arvida, JTB Architects and NZ Strong on this project.

Countdown Regent

Works are almost completed

Construction is almost complete on the extension and refurbishment of Countdown Regent.

The project is an extensive redevelopment of the existing supermarket including extension of the existing store, new online customer pick up area, courier pickup area with canopies, instore pharmacy and alterations to the existing supermarket.  The extension to the store has been constructed with architectural precast concrete panels and structural steel roof.

Structus were engaged for structural and civil engineering design, seismic restraints design, seismic assessment and strengthening design, and construction monitoring

Auckland Normal Intermediate

Work is progressing on site at Auckland Normal Intermediate with much of the structure in place for a new 2 storey 10 Classroom Block and Multi-Purpose Space buildings. The new Multi-Purpose Space includes a central amenities pod and bleachers, and the 2-storey Classroom Block includes an engineered timber amphitheatre. These buildings are part of the masterplan to reinstate demolished spaces and to increase the capacity for an expected roll increase. Structus has provided structural engineering services for this interesting project.

Northland District Health Board – Te Kotuku Extension Project

Northland District Health Board – Te Kotuku Extension Project

Building consent has been issued and contractors engaged for the extension to the existing Te Kotuku maternity facility at Whangarei hospital.

The extension is a new level to the existing 3 storey building plus an upper level suspended concrete full length enclosed plant platform. A new 4 level Eastern circulation core will allow access to all levels with lifts and stairs, and links the Te Kotuku building with the existing hospital, while the new Western egress core will also cater for access to all 4 levels.

We look forward to seeing the progress of this highly complex project on site and working with Argon Construction.


We are pleased to announce that Craig Bell, Leticia Lum and Thomas Zhang have all been promoted in recognition of their continued leadership and commitment to their own development and that of Structus.

Craig and Leticia have been promoted to Lead Structural Engineer.  This newly created role acknowledges their position in the company and alignment with our culture of a high performing team.  Craig and Leticia both exemplify the values of being a Senior Leader in Structus, consistently demonstrating dedication to their work and clients, building strong relationships, and supporting our team of engineers and drafters.  Craig’s technical skills and attention to detail have been valuable for our clients in the Healthcare, Education and multi-story Residential sectors.   Leticia has continued to develop her skills and strengthen relationships within the Retail and Residential sectors as she leads many projects throughout New Zealand.

Thomas has been promoted to Senior Structural Engineer.  Thomas has further developed his technical skills as an engineer and has also stepped into the role of Project lead. Thomas has extended himself with a variety of challenging projects, supported by the senior team at Structus.  He has been working across Retail, Education and Healthcare sectors and has developed a keen interest and skillset in Engineered Timber design.

We look forward to seeing these three grow into their new roles and continue to develop in Structus.

Site Visits

As a team we enjoy visiting our sites during the early phases in construction monitoring.  It’s a great opportunity for our engineers and drafters to see the work that the team have been designing.  We recently visited a couple of our projects in construction on the North Shore, Auckland.

110 Milford is a high-end residential apartment development built over 6 Levels with a commercial space and carpark on the ground level.  The raft slab and retaining has been completed, the tower crane is up, and the podium level is underway.  The superstructure is typically precast rib flooring on steel sway frames and precast concrete shear walls.  Waide Construction are the main contractors.

Aria Bay is new Aged Care residences built in 2 Blocks 5 storey high, following completion of the adjacent 4 storey Care Facility in 2020, which was also engineered by Structus.  The RC bored foundations are complete, ground beams underway and the tower crane is going up.  The superstructure is typically concrete shear walls and steelwork with composite metal deck slabs.  This exciting stage will complete the Village by connecting the Care Facility and the rest of the Village to the Apartments through several new link structures up to 3 Levels high.  NZ Strong are constructing Stage 2 for Arvida Group.

Countdown Richmond

Construction is complete and the new store is Open. This has been a great project to be involved in, with Woolworths New Zealand committed to sustainability and achieving Green Star accreditation as part of their 2025 Sustainability Plan. This store is their greenest store built to date.
Sustainability was a key factor in the design and build for Countdown so we designed with consideration for sustainable products, life cycle impacts, and responsible building materials integrated into the structural design. Targeted credits were achieved with incorporation of recycled aggregate in the form of pulverised fly ash used as a cement substitute in the concrete, an overall reduction in the steel mass, when compared to a reference case building, and through a pragmatic design and analysis approach.
Structus has enjoyed delivering structural engineering services with an excellent project team on this exciting job.

Countdown Te Rapa

Construction is now complete for the refurbishment and extension of Countdown, Te Rapa.  Leticia Lum, Salvie Dan and Gilbert Han have worked together to deliver this refurbishment in Hamilton, with construction going smoothly and to programme.

The team have done a great job on delivering this project, a redevelopment of the existing supermarket including new online pick-up area, canopies, standalone pharmacy and alterations to the existing supermarket.

Structus were engaged for structural engineering design and construction monitoring services.

Countdown Richmond

Construction is well underway in Richmond, Nelson for an exciting new green star Countdown supermarket. The supermarket building consists of 4,500m2 of Countdown Supermarket and 2 no. additional retail tenancies, drive through covered loading dock, standalone walkways and pickup canopies. Structus are providing full structural engineering design, sustainability design inputs, 3D Revit documentation and construction monitoring.
