BIM - Analysis

Work Efficiency

BIM work efficiency

If we see the graph above, it shows that work efficiency can be increased if we use BIM as compared with traditional practices. From the above case and some survey we have prepared a chart for analysis of work efficiency in which we can see if we are adopting BIM technology then we can increase our efficiency by Approx. 40% than traditional practices.


BIM Rework

The above graph shows the rework analysis between BIM and Traditional working methods which shows that rework in BIM based projects can be less than the traditional work projects. Almost about 90% of rework can be reduced by the use of BIM. As we have the model in pre planning stage we can detect the flaws in the work during pre construction stage and take a suitable alternative for performing the work.

Communication Gap

BIM communication gap

Lots of errors in construction process acts to due miscommunication or lack of communication. But in BIM process we have to coordinate with each contractor or each senior faculty included in the project activities. So there are very few chances of miscommunication. And also all the issues are resolved in planning stage so we can have better communication and also get the expertise advices regarding the particular task or work or issue.

BIM Workflow Vs Traditional work

With the emergence of BIM technology and its implementation in the projects ensures the stakeholder's interoperability between the technologies and the software applications.

BIM authoring tools organize and understand the parameters and the object data individually.

The below figure represents the time and effort relationship between BIM and the traditional CAD workflow across the various project stages:

BIM Workflow

Regarding project workflow, successful BIM implementation entails a front-loaded design process, where most of the modeling time is during the design and the development phase.

During the site visits, reports and documentation, the workload are approximately small which is beneficial in the front-loaded projects that reveal potential design problems early on, and the design issues are sorted soon by the design team?

Whereas, in the traditional design workflow using the CAD tools, most of the drawing takes place during the design development and thus, design changes tend to happen later in the project timeline proves to be costly than making changes early in the schedule.

The graph shows how the design change impacts the various stages of the project: The ability to affect cost and performance of a project with the design change is conversely correlated with the expense of the design change. In the above graph, the (3) curve represents traditional CAD process (2D-drafting process) while the curve (4) symbolizes the BIM drafting process. When using the BIM technology, most of the workflow is completed during the early stages of the project which eventually means that design changes have a better positive impact on the project at an overall low cost.
