4D BIM

Building Information Modelling (BIM) allows project managers and different people involved in the project with different backgrounds to get the accurate information about the project and monitoring of activities. The project manager and client can use the visualization aspects at any stage of the project to monitor the activities and cost flow. BIM improves the construction planning and design efficiency by integrating the 3D model and schedule of the project at one platform.

 

We take a three-step approach to 4D Scheduling:

1.Verify  : Using 3D models, we verify the construction documents for any inconsistent or missing representations of work.

2.Link    : We then combine the 3D models with the construction schedule to increase our understanding of project logistics.

3.Refine : Using the baseline schedule and the 4D simulation of the construction site in 3D space we analyze the time and budget            constraints as well as identify any opportunities to improve the project.

Benefits of 4D Scheduling with BIM Platform

The benefits of 4D models based on the BIM platform can be measured in two categories: (1) Tangible Benefits, and (2) Intangible Benefits. While the savings in cost and time, risk mitigation, conflict detection, reduction of complaints, improved productivity and enhanced quality are tangible benefits, a significant intangible gain seems to be in using the 4D models to communicate project parameters visually to home building owners

Tangible Benefits: Savings in Cost and Time, Risk Mitigation, Conflict Detection, Reduction of Complaints, Improved Productivity, Enhanced Quality, etc.

Intangible Benefits: Improved Communication among Various Division. Communicate project parameters visually to non-technical stake holders and get their buy-in.

Improve Subcontractor Coordination: Subcontractors have reported increased field productivity, less rework, and fewer change orders and Requests for Information (“RFI”) when using 4D models as coordination tools. The work of related subcontractors is typically coordinated through 2D overlays, which allow a project team to identify some spatial conflicts in the design. However, the construction phase can introduce entirely new spatial conflicts that are very difficult to identify with 2D overlays. This issue is resolved through the use of 3D and 4D models by subcontractors.

Optimize Resource Utilization: The use of a 4D model allows for the optimization of labor and Equipment utilization through the analysis of spatial conflicts among crews and others.
