What is 4D BIM (Building Information Modeling)?
4D BIM (Building Information Modeling) is a method of connecting data to an information model that adds another dimension to the data.
4D BIM is part of the BIM process, linking 3D models to information in the AEC industry (Architecture, Engineering, Construction industry). Using 4D is about creating an information model, adding scheduling data to different components, generating accurate programme information and enabling step-by-step visuals of your project development.
4D models benefit all team members (i.e., architects, engineers, etc.) since it helps them visualize the project’s timetable to assure the project’s success and timely completion.
Time-related information is associated with different components of an information model in 4D BIM. Details on the lead-time, building, and installation period, curing and drying allowances, sequencing, and interdependencies with other areas could be included for a given element or work area. Planners can easily construct correct project programs based on one dependable source of federated data with this data included. The graphical representations of the various activities and elements within those programs can be readily linked. The addition of time-related attribute data allows for the creation of 3D representations of a project’s progress, demonstrating how it will be built and how the structure and surrounding site will seem at each step. It improves site efficiency.
What are the benefits of 4D modeling?
- Site efficiency improvements
- Better team collaboration and communication
- Effective prototype assets in a virtual environment
- Provide rapid feedback on design or methodology changes
- Reducing overall delivery costs for clients
- Quality improvements
- Promote transparency
4D BIM is an effective tool for communicating the impact of constructed assets to local stakeholders during construction and afterward.
