By harnessing the power of Digital Engineering, we effectively unlock value engineering, sustainability and innovation opportunities to enhance and transform infrastructure construction and maintenance.

Our Digital Engineering team of around 25 specialists including BIM Managers, Technicians, GIS professionals and Systems Experts supports the delivery of capital infrastructure, building projects and maintenance contracts across Downer’s Transport and Infrastructure and Hawkins businesses in New Zealand.

3D Modelling – Build smarter from the start

Our “Model First Approach” puts emphasis on the design 3D models and enables Downer to build directly from them. When combined with automation, we produce high quality 3D representations of the “as-built” environment that is delivered monthly as the project progresses leading to efficient project handover.

3D Coordination & review – Reduce rework

By reviewing all discipline models in a single environment, we achieve design coordination and planning before physical works are undertaken.

This proactive approach identifies clashes early, minimising on-site rework and saves time and cost.

4D Simulation – Visualise the program

We combine 3D models with the construction schedule to create 4D simulations. These visual timelines help validate program accuracy and engage stakeholders, ensuring everyone understands the build sequence.

Geospatial intelligence – Connect data to place

Our GIS environment gives a live, visual view of site conditions and processes. From permit boundaries to traffic impacts, teams can see how activities affect the network. Integrated with survey equipment, it supports precise scoping and maintenance planning. Client asset data is linked to as-built objects for full lifecycle visibility.

Digital twin with AR – Bring projects to life

Downer’s Digital Twin technology merges 3D models, GIS and asset data into one dynamic view. Combined with augmented reality, it transforms how stakeholders experience projects making complex information clear and interactive.

Machine avoidance – Safer, smarter sites

We integrate 3D digital shields with location-aware machinery to prevent clashes with critical assets. This technology boosts productivity and enhances safety performance across the site.
