Building Information Modeling entails the construction of a building using the pc 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 genuine object (although one might not want to rotate a building in the physical world…)

Every section of the building is virtually constructed using the pc; the walls, floors, doors, windows, other architectural elements as well as the services like the electrical wiring and plumbing.

One of the advantages of Building Information Modeling is that one may avoid ‘clashes’ while constructing the building, that is, avoid elements 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 can be an almost instantaneous and error-free process. But Building Information Modelling Halesown 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 move to leading of a building forward by 10 feet, the moment he does this on to 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 has been 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 may also be generated immediately and modified instantaneously should there be a change in the 3D model. Again, in earlier times, this modification had to be done manually with all the inherent disadvantages of this type of process.

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

If one knows its capabilities, one will recognize that it can no more be an option; this is a necessity.
