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, 340-tonne steel bridge structure was successfully moved into position during the rail occupation.
