#13 - Design Benefits of BIM

• Earlier and More Accurate Visualizations of a Design: The 3d model which is generated by BIM tools can be used to visualize the required perspective at any stage of the process with consistent data.

• Automatic Low-Level Corrections When Changes Are Made to Design: If the model is created by means of parametric rules, as a result, the generated model can be free of any geometric, coordination, or spatial errors. This can reduce the user’s requirement to make design adjustments.

• Generation of Accurate and Consistent 2D Drawings at Any Stage of the Design: Drawings that are consistent and accurate can be generated for any specific view of the model. Which reduces the time required and errors generated to produce any drawings. Moreover, if there are any changes made in the design, accurate and consistent drawings can be generated as soon as the model is generated.

• Earlier Collaboration of Multiple Design Disciplines: More than one design discipline can work simultaneously by means of BIM technology. This reduces design duration and design errors. Moreover, it also gives earlier visualization into the design and as a result, gives more opportunities for continuous design improvements. This is more cost-effective than waiting until the design is nearly over.

• Easy Verification of Consistency to the Design Intent: Advanced 3D visualization and quantity extraction can be done via BIM, which allows more accurate cost estimates. A building model can be used to check quantitative and qualitative design intents by means of computerized evaluations.

• Extraction of Cost Estimates during the Design Stage: Cost Estimates can be extracted at the design stage by BIM technology. BIM can extract more accurate quantities and spaces which are to be used for cost estimates. Further, as the design progresses, more specific quantities can be extracted which results in more precise cost estimates. These precise cost estimates allow making a better decision concerning costs by means of BIM. It is viable to make the contractor a project team member who is liable for building the structure. Their expertise is also required to make precise cost estimates and constructability insights.

• Improvement of Energy Efficiency and Sustainability: If the energy evaluation tools are linked with building models it permits evaluation of energy use in the design stage. This is not possible in conventional 2D practice. And even if it applies in a 2D workflow; it is performed at the end of the process which reduces the possibilities for modifications that may improve the building’s energy performance. The ability to link the model to energy analysis tools provides many opportunities to improve building quality.
