WHAT BIM IS

Building Information Modeling (BIM) is a digital representation of physical and functional characteristics of a facility. A BIM is a shared knowledge resource forinformation about a facility forming a reliable basis for decisions during its life-cycle; defined as existing from earliest conception to demolition.
4D BIM, an acronym for 4D Building Information Modeling and a term widely used in the CAD industry, refers to the intelligent linking of individual 3D CAD components or assemblies with time- or schedule-related information.
6D BIM, an acronym for 6D Building Information Modeling and a term widely used in the Construction industry, refers to the intelligent linking of individual 3D CAD components or assemblies with all aspects of project life-cycle management information.

Top Ten Advantages of BIM Modeling

1. Capture Reality.
The wealth of information that’s easily accessible about project sites has expanded greatly with better mapping tools and images of Earth.

2. Waste Not, Want Not. With a shared model, there’s less need for rework and duplication of drawings for the different requirements of building disciplines.

3. Maintain Control. 
The digital model-based workflow involves such aids as autosave and connections to project history so that users can be certain they’ve captured their time spent working on the model.

4. Improve Collaboration. 
Sharing and collaborating with models is easier than with drawing sets, as there are a lot of functions that are possible only through a digital workflow.•Grade

5. Simulate and Visualize. 
There are an increasing number of simulation tools that allow designers to visualize such things as the sunlight during different seasons or to quantify or the calculation of building energy performance

6. Resolve Conflict. 
The BIM toolset helps automate clash detection of elements such as electrical conduit or ductwork that run into a beam. By modeling all of these things first, clashes are discovered early, and costly on-site clashes can be reduced

7. Sequence Your Steps. 
With a model and an accurate set of sub-models for each phase during construction, the next step is a coordinated sequencing of steps, materials, and crews for a more efficient construction process.


8. Dive into Detail. 
The model is a great end point for a lot of knowledge transfer, but there’s also a need to share a traditional plan, section, and elevation, as well as other reports with your project team.

9. Present Perfectly. 
With all of the design completed on a capture and alteration of existing reality, the model is the ultimate communication tool to convey the project scope, steps, and outcome.

10. Take It With You. 
With the added benefit of a model that’s tied to a database, you have a great deal of intelligence at your fingertips.
