4D and 5D BIM Modeling
4D and 5D BIM Modeling
What is 4D BIM? • 4D BIM is one of the technologies that has found importance in the Building Information Modeling world. • It represents building data in form of time line featuring duration of construction integrated with 3D geometry of building in a simulation format. It evaluates the overall design features on the construction schedule and workflow.
What is 5D BIM Model?
5D BIM
• 5D BIM represents the costing and budgeting of any building that is getting constructing. We can extract material take off, quantity take offs, list of components with pricing and overall schedules using 5D. • 5D BIM is the process of producing accurate cost estimates from the components of the information model. The main benefit of 5D cost estimating services is it includes all information related to the building and its components.
Understanding the Technology
This technology is extremely useful in the pre-construction, construction and post-construction phase of the building project by analyzing the building information model. A 3D BIM modeling gives an additional information i.e. four dimensional information (time), fifth dimensional information (costs) and sixth dimensional information (facility management). BIM allows the Architects and Engineers 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.
Purpose of 4D BIM Technology • • • •
The main purpose of performing the 4D BIM modeling process is to prepare a 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.
Purpose of 5D Technology
• 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 assist the engineers to prepare a project plan and estimate project costs efficiently.
