Downer has over 20 digital engineering specialists across the country supporting our customers and project teams to digitise and transform infrastructure delivery.
Our vast array of digital tools and digital engineering use cases is changing the way we deliver projects.
We are also firm believers in the benefits that can be gained from the collaboration and cultural changes digital engineering tools can create. Our experience in delivering digital solutions for our customers ensures we understand what’s important to their success. Our ongoing work with customers such as Auckland International Airport, KiwiRail and City Rail Link demonstrates this commitment.
Downer has representation on the BIM acceleration committee (BAC), industry training froups (BIMinNZ) and local forums (BIMinNZ-Auckland) to support the industry and maintain its currency with regard to current and relevant standards in New Zealand. We track international standards and are able to adapt and or advise on best practice depending on the requirements of a project.
We continue to develop our own standards, methods, and processes in line with the New Zealand BIM handbook and ISO 19650, which reflects best practice methodology both locally and around the world.
A 3D BIM model is being used to track the projected carbon footprint of Auckland’s largest transport project, the City Rail Link (CRL), in an Australian and New Zealand first. Downer’s digital engineering team is working closely with CRL, designers, construction teams and MEP subcontractors to produce a LOD 400 Construction BIM model to optimise construction planning and execution. As the design progresses, the BIM model is updated, and monthly take-offs produced with data on material quantities used by each of the design packages. These quantities are then converted into a carbon footprint by the Sustainability team and compared against the reference design. An additional opportunity afforded by BIM is 4D modelling, including time as the fourth dimension to visualise the various stages of construction and test different sequencing to identify efficiencies in time, materials, and energy.
Downer is using digital tools to create, capture, and integrate data on a highly congested piece of rail network in Auckland. Our digital engineering team is using digital tools such as Revizto to coordinate with the design team and BIM 360 to collect asset data and enable informed whole-of-life decision-making. Digital forms and permits are being utilised and through the use of mobile tablets, the latest information is accessible to teams anytime, anywhere allowing better information capture to enhance safety and quality performance.
Trentham to Upper Hutt (T2UH) is part of the $300M Wellington Metro Upgrade Programme (WMUP), a long-term programme of rail renewal works being delivered by KiwiRail and Metlink and funded by Waka Kotahi. It is KiwiRail’s first BIM enabled project and part of a wider BIM pilot to support KiwiRail's focus on digital connectivity and innovation. Understand more about how collaboration led to innovation on this project.
