How Bim Impriives Safety 2 From 5

For example, halfway through a roadway design project the profile may need adjustments to a vertical curve and the grades.

By adjusting the profile, all of the related design elements update automatically, allowing the designer to instantly see the impact.

In this way, BIM facilitates evaluation of many more design alternatives.

As part of the design process, civil engineers can leverage the information model to conduct simulation and analysis to optimise the design for constructability, sustainability and road safety.

 Finally, with a BIM process, design deliverables can be created directly from the information model. Deliverables include not only 2D construction documentation, but also the model itself and all the rich information it contains, which can be Leveraged for quantity take-off, construction sequencing, construction

stake-out, as-built comparisons and even operations and maintenance.

In the case of construction stake-out, digital points are added in the office to the information model and can be sent directly to total station equipment on site.

This equipment has the ability, once coordinated to stake-out numerous points robotically removing the need to generate stake-out points from 2D CAD or paper drawings.

This process allows a more efficient and accurate way to link the office to the site and through verification of the as-constructed, links the site back to the office.

The use of modeiling,3-D visualization and analysis is nothing new for road and highway design professionals, but with traditional drafting-centric approaches, design, analysis and documentation become disconnected processes, making evaluation of what-if scenarios inefficient and cost prohibitive.
