4D BIM is also referred as simulation-based modeling which plays an integral part in construction planning to evaluate the impact of design features on the construction schedule and workflow. 5D BIM is the process of producing accurate cost estimates from the components of the information model. 4D and 5D BIM has brought a prominent change in the building construction industry. 5D BIM is the process of producing accurate cost estimates from the components of the information model. The main benefit of digital building information model is it includes all information related to the building and its components.
Various activities can be performed in the pre-construction, construction and post-construction phase of the building project by analyzing the building information model. A 3D BIM model gives an additional information i.e. four dimensional information (time), fifth dimensional information (costs) and sixth dimensional information (facility management). BIM allows the architects, engineers and construction engineers to develop 3D digital information model for all type of simple and complex building projects. BIM model is a 3D database providing end to end information related to the building project.
The main purpose of performing the 4D BIM modeling process is to prepare construction task schedule by linking the model elements to the timeline. 4D BIM creates a simulation video for the construction project in 4D environment showing every stage of building construction. 4D models create virtual mockup of the construction system design which identify work-flow based clashes and also manage the supply chain for materials and labor required on the construction site. Virtual mockups are also known as sequenced based simulations which help contractors to communicate the complex processes to whole team improving overall productivity onsite.
The 5D modeling process adds cost information in the 3D model. The cost data is integrated within the BIM model objects themselves. The 5D BIM modeling helps to create a relationship between elements and include the properties and specification of each element and object where we can extract complete and accurate information from the model used for costing.
4D and 5D BIM modeling process assists the engineers and architects to detect and resolve schedule clashes. Schedule clashes mainly occur when the schedule for two or more tasks is wrongly arranged at the same time. If any kinds of modification are made within the design, the project task schedule and cost information also gets automatically updated according to the modified design. Thus 4D BIM and 5D BIM assists the engineers to prepare project plan and estimate project costs efficiently.
