A lot of confusion can exist as to whether an Engineer is required for residential renovations. Sometimes it is thought that if it requires a Building Consent, a Structural Engineer is required. However you may also need an Engineer to confirm that your renovation has not altered the structural integrity of your house. We discussed this topic on our latest blog post on our website. You can read it below:

We recently undertook Construction Observation on behalf of Batchelar McDougall Consultants who are based out of Christchurch for this category 1 historical church located in St Luke's / Mt Albert. The original church structure was left untouched but a new building was constructed to provide a space for hospitality services and office spaces for people that work within the church. The goal was to provide a modern building that kept in line with the gothic theme of the original church structure.

The project was recently featured in Here magazine & on Architecture Now's website.

Abacus Engineering worked on this stylish CLT (cross-laminted timber) sleepout / garage addition to an existing property in Ostend, Waiheke last year. The design was initially done in 2022 and consent was obtained. However the owners never completed the project and it was sold with the design a short time later. Abacus Engineering were contracted in 2025 to help assist with completion of the project.

CLT is a high strength wood engineered product that laminates timber sheets in alternating grain directions. This allows the engineer to overcome the critical weakness of timber which is being weak against the grain. As a result the CLT members are able to act as structural elements, which provides a high strength, cost effective solution with a elegant timber finish.

For the Redbull Cliff Diving Platform we used Multiframe to create our tower model for analysis. Multiframe is a finite element analysis program that can be a bit more intuitive than the other typically used programs. The model was important as it allowed us to check the bottom scaffold standards for ratcheting of forces down the structure, especially considering the forces acting on the front of the tower from the cantilevering dive boards.

See some of the photos of our model below.

One of our more unique projects we undertook in the past few years was the Redbull Cliff Diving Platform, for the Red Bull Cliff Diving in Auckland, January 2024.

This was a 27m high scaffold tower, with 4 diving boards. One at 6m, 10m, 21m and 27m. The structure was Octagon shaped in plan. Due to its height and small plan area (9m x 9m octagon shaped) the structure was torsionally sensitive. Additionally it was erected at the exposed Queen's Wharf in downtown Auckland. A large amount of ballast was required to keep the tower secure from wind coming off the downtown Auckland harbour.

Initially the diving boards were not going to be clad due to the increase in wind load that would result on the tower. However it was eventually decided this was a suitable location for additional advertising. This cladding increased the torsional forces on the tower and meant further ballast was required. Due to the octagon shape of the tower, we were able to account for vortex shedding which slightly reduced our wind loads.

The event was quite the spectacle and saw a large crowd form in downtown Auckland on an overcast January day for the final event in the Red Bull Cliff Diving world tour.

One of our most common questions we get asked is whether or not you need a consent for a retaining wall. Auckland City Council recently updated their guidance on retaining walls. Whether a retaining wall consent (for Auckland Council) is required can be summarised into 3 categories.

1. Retaining wall less than 1.5m high with no surcharge - NOT REQUIRED.
2. Retaining wall less than 1.5m with a surcharge - REQUIRED.
3. Retaining wall greater than 1.5m with or without a surcharge - REQUIRED.

Often confusion lies around retaining structures less than 1.5m and what is a surcharge. A surcharge is a downward pressure exerted on the soil that causes a subsequent outward pressure on a retaining wall. Even when like-for-like structures are replaced, if a surcharge is exerted from a structure on the ground it may cause the soil to shift or even fail during replacement. This is why consulting a structural engineer may be important for replacing retaining walls that is supporting a building, footpath or boundary.

Citta Apartments is a large residential apartment complex that sits at the top of Symond's Street and wraps around the corner towards Khyber Pass.

Citta Apartments had to undergo roof repairs due to leaking on the upper level. When the roof was removed, fire separation of the upper units was looked at by Auckland Council and found to be non-compliant. As a result significant fire engineering upgrades were required which Abacus Engineering oversaw. This include the photographing and logging of over 2000s penetrations between neighbouring units by Kieran Lake of Abacus Engineering!

Abacus Engineering were engaged to help convert an old warehouse in Lincoln Road into a new Tai Ping Supermarket.

There are 10 Tai Ping Supermarkets in Auckland and Abacus has been involved in 5 of them. The Henderson Tai Ping Supermarket is the most recent one Abacus has worked on.

Challenges with this particular conversion arose from the need to strengthen the existing Posi-STRUT trusses to meet the new commercial loads for the supermarket.

This commercial unit in Wairau Road on Auckland's North Shore, required urgent remedial works following the Auckland Anniversary Floods.

Abacus Engineering were contracted to assist with the structural design of the new bracing systems, extension of the shop front canopy and upgrade the fire engineering systems.

The shop and factory out the back are now occupied by a coffee roastery in 2026.
