This is one of Aotearoa’s most iconic and significant reinstatement projects in history, posing very complex engineering and health & safety challenges – carefully managed through close collaboration with project stakeholders.
The Canterbury earthquakes of 2011 caused significant damage to the historic Cathedral. Stabilisation presented significant technical engineering, construction and health and safety challenges given the site constraints, biohazards, and the badly damaged structure. At the same time the work had to preserve the historical character and facilitate the Cathedral’s restoration phase.
ACE said “Holmes and Naylor Love are recognised for the expertise, commitment and a deep understanding of its structural challenges that had to be addressed to set up the cathedral for the project’s reinstatement phase.”
As well as this incredible win, we are proud to have been awarded MERIT for the Observatory Hotel at The Arts Centre – Christchurch Te Matatiki Toi Ora.
The Arts Centre’s F Block, which was structurally compromised during the 2010-2011 earthquakes, was restored to preserve the building’s heritage, strengthened, and repurposed to house the luxury hotel, bringing a vital revenue stream for the Arts Centre. Clever engineering helped restore this impressive heritage building to its former glory.
“Holmes is recognised for its expertise and commitment to preserving the heritage of this building while facilitating its repurposing as a hotel, and its collaborative, can-do attitude which has made this possible.” – ACE
About the ACE Awards:
New Zealand’s leading engineering consultants were celebrated at the 2023 ACE Awards Gala in Wellington on September 21. An industry calendar highlight, the awards recognise the consulting excellence that underpins some of the country’s most impactful projects – from shared pathways that provide low-carbon transport options to restorations of culturally significant buildings and equipment repairs to ensure business continuity. ACE Chief Executive Helen Davidson says the event is the pinnacle of achievement for the outstanding talent that exists within the country’s professional services consulting sector, especially at a time when these consultants are operating in a very complex environment.
Our Fire Engineering team in Aotearoa New Zealand were part of the project, led by BECA.
“Great pains have been taken to restore this library following earthquake damage and the efforts to justify the building through repairs and upgrade are admirable, providing enormous savings on the alternative of new construction. The design implemented improvements beyond code requirements under severe working constraints as the library remained in use throughout.
There was impressive communication of the engineer’s role in the process at a digestible level for everyone involved to understand. This communication of the complex works to building users throughout the project stands out as a good example of the importance of our profession: teamwork, communication, collaboration and responsiveness”.
The prestigious IStructE Awards celebrate engineering excellence on an international scale. Congratulations to all our project partners:

‘For returning Kiwi with offshore experience in sustainability and design there has never been a better opportunity to bring those skills home and get involved in a wide variety of projects.’
Lisa Oliver, Project Director here at Holmes was recently interviewed by Kea New Zealand about her passion for mass timber design, her involvement in sustainability, and how Aotearoa New Zealand is well placed to lead the repurposing and strengthening of existing buildings.

Established in 1968, the Structural Awards are the world’s leading awards for structural engineering excellence. Winning both of these prestigious awards is an incredible achievement for everyone here at Holmes who worked on this exciting but challenging project that won–The Christchurch Town Hall. And our team of experts were not only the structural engineers but also the fire engineers for this important restoration project.
This conservation project demanded a full spectrum of technically complex structural and geotechnical solutions. Solving ground stabilisation issues and predicting the future performance of the structure and foundations were achieved through detailed analysis and intensive co-ordination between the geotechnical and structural engineers.
Complex analysis was employed to minimise the strengthening work required for the superstructure. The result preserves the original character and style of the building and protects the existing fabric – a positive both for sustainability and our client–Christchurch City Council.
The Judges commented, “This project is an excellent example of what structural engineers can bring to a devastated existing building. By understanding its behaviour and failure, the team was able to repair and preserve this important structure”.
Acclaimed for its architecture and acoustics, Christchurch Town Hall is a local landmark. Following devastating earthquakes in 2010 and 2011, the original building required significant structural repair and strengthening of the supporting foundations.

Ground stabilisation issues were solved and the future performance of the structure and foundations was predicted through detailed analysis and intensive co-ordination between the geotechnical and structural engineers.

Lockdown has put a pause on the opening of Te Pae (more than once!), but we’re just as excited to see this impressive NZ $475M convention centre completed and open to the public soon.
Te Pae, Christchurch’s new Convention and Exhibition Centre, is an ambitious project, creating a large mixed-use precinct in the heart of the city. The development has a large and varied stakeholder group, including Te Rūnanga o Ngāi Tahu, Christchurch City Council, and the private sector—as well as the communities the centre will serve. Capable of hosting up to 2,000 delegates for a variety of national and international events, the state of the art centre includes a 1,400-delegate auditorium, a 3,600m² exhibition hall and 1,600m² of meeting rooms. This is a project of significant local and national importance, delivering a vital events hub that will attract domestic, national and international visitors and events.
In the challenging geotechnical conditions and seismic environment, our experience has been invaluable in designing a structure to stand the tests of time and form an important part of the city’s cultural and commercial landscape.

Exciting news, Commercial Bay won the Supreme Award for Structural Engineering Excellence 2021 at the Structural Engineering Society NZ (SESOC) Awards.
We are very proud of our team and our project partners that worked together to create a truly outstanding result. Commercial Bay isn’t just an incredible feat of engineering but an impressive mixed-use space like no other in New Zealand.
At this stage it isn’t safe for anyone to go inside the Christ Church Cathedral due to the risk of falling materials, debris, and the potential for it to collapse. This drone footage, captured by engineers, has been invaluable for architects, heritage professionals, engineers, and contractors to view the interior and assess the damage without the need to endanger lives.
The current condition inside the cathedral is clearly shown in the drone footage (captured by Beca) and gives us an indication of where the structural damage is more severe. It allows us and our project partners to better determine and understand the Cathedral, and to help direct this important reinstatement project!
