An architecturally design single level house with a mezzanine floor in Mangawhai was completed in 2023. SENZ was engaged by the client to undertake the structural design of this dwelling, including foundations, floor slab, clay block and concrete wall construction, as well as a timber frame roof. The structure was complex due to the using of multiple construction material, including concrete, clay block, timber, steel, and blockwork. Large opening were created and made possible by utilising deep concrete beams.

Key personnel on this project was Sadeer Kattan (Chartered Structural Engineer), and Faris Kattan (Senior Structural Engineer).

This seaside house in Christchurch faced significant complexities during design due to the presence of liquefiable soil, as well as the client’s requirements to combine precast concrete, in-situ concrete, timber and steel within the building structure.

Key personnel on this project was Shaneel (Chartered Professional Engineer), and Aness Kattan (Senior Structural Engineer).

Did you know many verandahs under 30 square metres may not require building consent in New Zealand?

We recently had the pleasure of delivering structural designs for two fantastic residential verandahs, both cleverly designed to fit within these exemption criteria. The result? Beautiful, functional outdoor living spaces for our clients, delivered with a more streamlined and cost-effective process.
Our team specialises in creating elegant and robust structural solutions that not only meet the NZ Building Code but also maximise what’s possible within the scope of building consent exemptions.

Planning to enhance your outdoor living space this summer? Let’s talk about how we can achieve your vision efficiently.

Seismic Assessment Strengthening

St. Paul’s Church, Huntly – job 014-008

Client: St Paul’s Parish

Architect: BTK Architects

Originally built in 1934, the Church underwent further addition over the years, with the Church Hall built in 1956, and later extended in 1998.

SENZ carried out a Detailed Seismic Assessment in late 2018, and assessed the Bell Tower at 28% NBS, while the Church was assessed at 45% NBS. SENZ recommended that the Bell Tower is temporarily strengthened while a strengthening design is undertaken, and funds are raised to carry out permanent strengthening. SENZ provided the Church with a temporary support structure to the Bell Tower, which remained in place until strengthening was completed in last 2025.

SENZ worked along with BTK Architects to provide a strengthening design the Bell Tower, which needed to adhere to the heritage status requirements for the building. SENZ’s solution was non-invasive, visually appealing, and did not impact the overall heritage look and feel of the building.

Construction was completed in November 2025.

Award-Winning Collaboration at the CPO Building Renovation

We’re thrilled to share that the CPO building renovation scaffold project, designed by SENZ in collaboration with our client Total Scaffold, has won the SARNZ Best Scaffold Award – Commercial $50,000–$200,000 category!

As the appointed structural design engineer, SENZ worked closely with Total Scaffold throughout both the design and construction phases. This project posed significant challenges, from strict load restrictions to spatial limitations within the historic building. Our team developed a multi-tiered bridging beam system and provided continuous inspections and engineering support to ensure every detail met the highest standards of safety and performance.

Highlights of SENZ’s contribution:

• Delivered a bespoke scaffold design to navigate complex load paths.
• Collaborated with Total Scaffold and the building’s engineers to validate critical support locations.
• Provided structural oversight and inspections during key build milestones.
• Helped achieve a safe, high-quality scaffold installation now recognised as award-winning.

Congratulations to Total Scaffold on this well-deserved recognition. SENZ is proud to have played a key role in the successful delivery of this complex and innovative scaffold system.

The AIA Smales Farm façade scaffold has taken home the 2024 SARNZ Award for Encapsulation of the Year, and we’re proud to have been the structural design engineers behind this remarkable project for our client, Total Scaffold.

Standing 30 metres tall, the scaffold was completed in six carefully planned stages. With limited tie-in points to the building, the design demanded innovation and precision. To meet these challenges, we engineered solutions including a monorail system for lifting façade materials and back-propping with bridging to keep traffic flowing safely through the basement.

This project showcases what happens when great engineering and expert execution come together. Congratulations to Total Scaffold on delivering an exceptional scaffold system worthy of national recognition.

Engineering Ingenuity at SkyCity Hamilton

SENZ was proud to partner with our client Total Scaffold on the SkyCity Hamilton scaffold encapsulation project — a job that pushed the boundaries of creativity and engineering know-how.

This project demanded more than just scaffold design; it required careful integration with the existing building to create a safe and practical solution. Key challenges included:

• Supporting scaffold directly on the roof of the building.
• Engineering large roof truss spans to achieve full coverage.
• Designing bridging beams carried on scaffold towers tied into the building’s columns.
• Reviewing the structural capacity of the existing building to ensure it could safely support scaffold loads.

By working closely with Total Scaffold, we were able to deliver a robust design that balanced safety, efficiency, and constructability — ensuring the encapsulation could be completed without compromising the building or project schedule.

Scaffolding Innovation at the Auckland Art Gallery Clocktower

SENZ is proud to be providing the structural design expertise for the façade scaffold and roof encapsulation at the iconic Auckland Art Gallery Clocktower, in collaboration with our client Erect Safe Solutions.

Working on a historic building always brings unique challenges. With very limited opportunities for bolted connections, our team engineered a solution that included:

• Large bridging on two elevations using steel beams, with SENZ providing the connection details for the beam-to-beam joints to create a continuous ring beam for the scaffold.
• Careful use of the existing building balcony to provide scaffold support.
• A staged construction approach, designed to reduce wind loading on both the scaffold and the heritage structure.

The scaffold remains in place and will be standing proudly for the remainder of the year, protecting this historic landmark while essential works take place.

A big well done to the Erect Safe Solutions team for their outstanding work on-site delivering this complex build.

Engineering in Action at Tower Hill Apartments

SENZ is proud to be providing the structural design expertise behind the façade scaffold and roof encapsulation at Tower Hill Apartments, in partnership with our client North Shore Scaffolding.

This project is a true test of scale and precision, featuring a 50m-high scaffold supported by a combination of sealed ground, the existing building, and cantilever brackets. With large roof spans exposed to significant wind loads, careful coordination with the building’s design engineers has been critical to ensure the safe transfer of scaffold loads into the structure.

Other key elements include:

• Integration of hoists and loading bays to support ongoing site operations.
• Engineering solutions for cantilever brackets and long-span roof encapsulation.
• Scaffold construction staged across elevations, with two sides already completed on site.

This is a project still in motion — and we’re excited to see it rise, stage by stage. Great work so far to the North Shore Scaffolding team on delivering such a complex build.

Aluminium is transforming lightweight construction in NZ. From stairs and bridges to rooftop access structures, its durability and low weight make it ideal for seismic zones like Wellington, Hawkes Bay, and Canterbury.

Aluminium reduces seismic loads, simplifies handling, speeds up installation, and offers long-term cost savings thanks to its corrosion resistance.

At SENZ, we’ve applied our aluminium design expertise to major projects like Christchurch’s One New Zealand Stadium. Our team was responsible for the structural design of the score screens, roof gantries, platforms and walkways—delivering lightweight, seismic-resilient solutions in collaboration with Monkeytoe Group and the wider project team.

Aluminium: lightweight, resilient, and cost-effective.
