Using 4D planning to streamline project delivery

On a recent rail duplication project in Melbourne, our team used digital engineering and 4D modelling to streamline the design and "rehearse" the construction of a 340 tonne steel bridge being launched over a waterway.

The 4D planning exercise was a game changer in helping the design, engineering and construction teams achieve an authentic digital rehearsal. The process helped identify and rectify early problems, including a clash between temporary and permanent retaining walls, as well as signalling cables and wall panels.

After months of painstaking planning and the ‘virtual launch’,  the 63 metre long, 340 tonne steel bridge structure was successfully moved into position during the rail occupation.

The project team received an innovation award for the work done on this project.
