What is 4D Construction?

As 3D building information modelling (BIM) continues to be the technology-enabled process for design delivery, construction firms have looked for ways to leverage these 3D BIM models for downstream construction workflows. Now, engineers are incorporating 4D modelling to their workflows. The concept adds a time dimension to the 3D CAD model that enables teams to analyse the sequence of events on a timeline and visualize the completion of construction tasks. This concept can be extended to 'nD', where additional dimensions represent other types o... (read more)
