Drafting Services - Building Information Modeling

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 can be moved and rotated as if it were a real object (although one may not want to rotate a building in the physical world...)

Every section of the building is virtually constructed on the computer; the walls, floors, doors, windows, other architectural elements in addition to the services such as the electrical wiring and plumbing.

One of the benefits of Building Information Modeling is that one can avoid 'clashes' while constructing the building, that's, avoid parts of the building unexpectedly interfering with each other during construction.

The other great things about Building Information Modeling have become high accuracy in construction drawings and in the other construction documents. By construction drawings one means the drawings which builders use while they are 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 done, generating drawings is an almost instantaneous and error-free process. But the specific advantage of Building Information Modeling is that when something is changed in a single drawing, other drawings are correlated instantaneously and automatically.

For instance, if the architect decides to go to the front of a building forward by 10 feet, the moment he does this on the floor plan, the 3D model and also all of the sections and elevations are updated in under a second with out a single line needing to be drawn by 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 prone to human error and long turnaround times. Both these factors are practically eliminated width Building Information Modeling.

~~ The Accuracy of Other Construction Documents ~~

Documents derived 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  3D Modelling Bromsgrove , this modification needed to be done manually with all the inherent disadvantages of such a process.

Building Information Modeling will with time become as basic a tool to architecture and construction as the calculator is to school students.

If one is aware of its capabilities, one will realize that it can no longer be an option; it is a necessity.
