Reinforcement fixers on site have found the 3D models very useful. For very complex areas where bars are very congested and complicated, the fixers have utilised the models to see what is happening and figure out what they need to do. Detailing the model has also allowed for detailers to see where areas are too congested, where concrete can not flow through the bars based on initial design proposals. Automatic scheduling of the rebar and model checking has also eliminated total errors on site.
