BIM is more integrated and more interoperable than traditional CAD (Computer Aided
Drafting) software.
BIM Features and Advantages
|
Facilitates collaboration and coordination amongst the various disciplines involved
in the pre-design, design, construction, operation and maintenance of new and existing
buildings. All parties to the construction team work on the same model, so that
changes are automatically coordinated.
|
|
There can be substantial design and construction cost savings.
|
|
Time is saved, as the ‘extra’ coordination checks are reduced or eliminated.
|
|
Fewer errors on site, as information is more coordinated.
|
|
Before the construction begins, as many uncertainties as possible are eliminated.
|
|
Rich information is available for facilities management tasks.
|
|
The information transfer in the process of handing over a building between the phases
of design, construction and operation, is smoother, as each discipline adds information
to the model and can refer back to it, at each step.
|
|
Productivity is increased, as information is retrieved faster and more easily.
|
|
Vital information, such as vendors of materials, location of quantities and estimation
and tendering information, is readily available and faster to retrieve.
|
|
The construction process is more efficient.
|
|
Assists in the life cycle assessment for the components of a building – assigning
a social, environmental, economic cost/benefit and impact.
|
After occupancy, the BIM can be used to improve understanding of the building’s
operation, to make adaptations, undertake renovations, additions and alterations,
faster and more cost effectively than with traditional processes.
BIM can be produced in several dimensions.
|
3D BIM
|
Three dimensional model.
|
|
4D BIM
|
A three dimensional model, with schedule and time constraint data added to it.
|
|
5D BIM
|
A 4D BIM with a cost dimension added to it.
|
|
6D BIM
|
All aspects of life cycle management are included in the model data.
|
It is more difficult to do this, since assumptions must be made about what existed at the time with respect to building codes, design standards, construction methods and materials.
BG&E has completed numerous design projects using BIM. Examples include:
The cost savings created by the use of BIM, generally more than cover the cost of generating BIM information.
You may have an existing building, for which you would like to have a BIM generated. Or, you may be considering a new building and wish to know more about how to incorporate BIM in your design process.
BG&E have strong capabilities in this area. For further information, contact:
