Building Information Modeling entails the construction of a building on the computer before building it in the physical world. This virtual model is built in three dimensions and will be moved and rotated as if it were a genuine object (although one may not want to rotate a building in the physical world...)
Every part of the building is virtually constructed on the computer; the walls, floors, doors, windows, other architectural elements plus the services such as the electrical wiring and plumbing.
One of the advantages of Building Information Modeling is that one can avoid 'clashes' while constructing the building, that is, avoid parts of the building unexpectedly interfering with one another during construction.
The other great things about Building Information Modeling have become high accuracy in construction drawings and in the other construction documents. By BIM Surveys Loughborough means the drawings which builders use while they're constructing a building. They are drawings like floor plans, elevations and sections. By other construction documents one means, amongst other activities, lists like material takeoffs and area statements.
Once the 3D model is performed, generating drawings is an almost instantaneous and error-free process. However the specific benefit of Building Information Modeling is that whenever something is changed in one drawing, other drawings are correlated instantaneously and automatically.
For example, if the architect decides to move to leading of a building forward by 10 feet, the moment he does this on the floor plan, the 3D model as well as all the sections and elevations are updated in less than a second with out a single line having to be drawn by way of a human. In earlier days, that was not the case; if there was a change in the ground plan then your elevations and the sections would have to be updated manually, an exercise susceptible to human error and long turnaround times. Both these factors are practically eliminated width Building Information Modeling.
~~ The Accuracy of Other Construction Documents ~~
Documents produced from the 3D model such as for example material takeoffs and area statements are also generated immediately and modified instantaneously should there be a change in the 3D model. Again, in the earlier days, this modification needed to be done manually with all the current inherent disadvantages of such a process.
Building Information Modeling will with time become as basic a tool to architecture and construction because the calculator would be to school students.
If one knows its capabilities, one will realize that it can no longer be an option; this can be a necessity.
