Advanced BIM software like Tekla Structures allows adding non-physical dimensions to the traditional 3D model. Adding information about the construction timeline, costs of the structure elements, quality and manufacturing records and maintenance requirements, we are creating another “dimensions” in our building information model. This is the essence of the BIM idea, and this is where Information Modelling happens. We can assign to the physical objects in the model all critical information related to the construction, maintenance, and operational stages of the structure’s life. This converts our simple 3D model into a multi-dimensional Single Source of Information.

An excellent example of adding useful information to the model is a 4D model. A 4D BIM model is a digital representation of a construction project that includes the fourth dimension of time. In addition to the 3D geometry of the building or structure, a 4D BIM model incorporates scheduling data to enable the visualisation and simulation of the construction process over time.

With a 4D BIM model, construction teams can better plan and manage project timelines, identify and resolve potential issues before they occur, and improve communication and collaboration among all stakeholders. It can also help optimise construction sequences, reduce waste and rework, and ultimately lead to cost savings and increased efficiency in construction projects. 4D visualisation also helps plan temporary works and safety measures required during construction.

A 4D BIM model is a powerful tool for construction project management that enables stakeholders to visualise and understand the construction process in a way that is impossible with traditional 2D plans or even 3D models.

4D models can be easily created in software like Tekla Structures. The short video below shows a simple precast core construction sequence animation. It was created using the Tekla Structures model and construction sequencer tool.
