4D BIM

TIME is considered as the 4th Dimension in BIM. Models are generally transformed from 3D to 4D either by adding the schedule related information to each element or by synchronizing the traditional project plan (data sheet) to the 3D model.

4D BIM Models are generally used to develop a sequencing animation of all the activities on-site along with the building construction, site-equipment, procurement etc. Sequencing animation helps the team to identify issues and plan the entire construction process avoiding any potential risks up-front.

Project Phasing

By simply grouping respective model elements into the phase they belong to by using time parameter, the project team can visualize the planning concept including construction zoning, temporary vs permanent structures etc.

Construction Simulation

Being able to visualize the project growing virtually before ground breaking gives great power to the stake holders. A general guide line while developing models for construction simulation is to consider develop the model exactly as it would be built on-site. This helps the team to easily incorporate particular date & time to each model element while developing the simulation.

Buildability Study

BIM models with sequencing animations enables the team to evaluate the buildability of a project. Buildability score, currently being practiced in the industry is a numeric value assigned to the design based on the buildable nature of the project.

Schedule Monitoring

By having the 4D BIM Models to monitor the construction activities on-site increases the understanding of the project status among all stake holders. 4D BIM Models help the team to assess the risks and plan the logistics accordingly.
