BIMSafe NZ Case Study

Ngai Tahu Otepoti Bim Safe

The Case study Project is the new ACC Building in Dunedin,  designed by Warren and Mahoney for Ngai-Tahu Property and the ACC Investment Fund.

This project went to tender in November 2021, with Naylor Love engaged to complete the works, with a target completion date of mid-2025.

The design of the new Ngāi Tahu Property building Ōtepoti was created within a collaborative co-design process undertaken by the Aukaha-Mana ahurea team-representing mana whenua and architects Warren and Mahoney.

Kāi tahu scholar Megan Potiki initiated the response with a rich cultural narrative and impeccable research on the site. Kāi tahu artist and Mana ahurea designer Kirsten Parkinson then led the design team response with a strong creative vision and deep understanding of Kāi tahu visual culture.

Months of co-design activated a design rich in ancient story, grounded with respect for the natural world and representative of a heritage building for the future of Ōtepoti-Dunedin.

The building features 9000 square meters of office space over three levels. The site is sloping and the building’s irregular shape created challenges for both the design team and the contractors on site. The BIMSafe NZ Project has engaged with the design team, engineers, civil and main contractors, and sub-contractors and is documenting case studies of workers engaging with BIM models to improve their Safety outcomes.

BIMSafe NZ Portal

In June 2024, the BIMSafe team will unveil an interactive web portal for the construction sector to access authentic New Zealand case studies demonstrating where BIM technology has improved health and safety.
 
This initiative aims to deepen the industry’s understanding and application of BIM throughout the construction process—from design through to facilities management—to create safer construction sites by mitigating risk and improving worker safety.
Portal users will be able to access specific information tailored to their individual roles (Client, Designer, Constructor, Operator/Facilities Manager), and unique needs. They can also submit their own case studies and share their knowledge and experiences to help develop this important industry resource.

BIMSafe NZ: ACC Ōtepoti building case study videos

Series 1 - ACC Ōtepoti building Case Study Videos

In this series on the Case Study, we look at the reinforcing steel in ground beams, and where these connect to the structural steel and wall panels. The use of the BIM models enabled prefabrication on site rather than in situ, which reduced high-risk work and work in a confined space.

The clash detection capability also significantly reduced the amount of rework required. The BIM model also reduced the gap between as-planned and as-built work, so that downstream work was not affected by what had been done previously.

Series 2 - ACC Ōtepoti building Case Study Videos

In series two, the BIMSafe project focuses on the visualisation, communication and collaboration involved in the installation of structural steel, floor, and façade. A four-D timeline animation of these elements was produced to reduce 1200 lines of sequence down to a 5-minute video. The plant deck construction and maintenance were revisited by the design and construction teams, and we also look at the use of Openspace from a project management and safety perspective.
