| Abstract | Linear, 2-Dimensional and now 3-Dimensional visualization are the current tools used in the construction planning area. It is time for a new dimension to be added - the dimension in which Planning Engineers are more interested. The dimension is TIME, which is now appropriate to add as the 4th dimension in construction planning. Current planning processes in the construction industry are still mainly based on two dimensional (2D) drawings. On the other hand model based planning methods can improve communication among project stakeholders and help to avoid planning failures. They also enable continuous optimisation of the construction project during early design phases by investigation of different design alternatives. Thus building models enable the project team to make a qualified choice from a range of possibilities. 4D construction planning is a process which enables clear visualisation of a construction programme as an animated sequence. 4D models are created by linking 3D Computer Aided Design (CAD) data with one or more programmes. This visualisation is then automatically updated any time the programme is updated. In particular, construction sequence planning as one of the key processes in a construction project, can benefit from model based working. Since the time schedule defines sequences of activities and allocates resources such as material and labour, it plays an important role in optimising and managing a construction project. In this respect, model based working can offer more to construction sequence planning than just a visualisation of the construction sequences, in which the term '4D simulation' is today commonly understood. 4D simulation of construction sequences is an adequate tool for visualizing inherently abstract and complex time scheduling data which are otherwise buried in deeply nested Gantt charts. 4D simulation software is, in principle, capable of generating visualisations which illustrate construction processes along the timeline. By linking the objects of a three dimensional model to the tasks in a time schedule, this assists in reducing major scheduling errors just by inspection and thus communication within the project team is improved. This paper discusses 4D simulation of construction sequences used in the construction industry and the potential benefits. |
