How Bim Impriives Safety 5 From 5

Road safety

Analysis to ensure safe stopping and passing sight distances is a key factor driving design decisions. Traditional sight distance analysis is based on mathematical equations applied to vertical curvature in the road profile. But, this approach fails to take into account factors such as horizontal

layout and visual obstructions. Integrating interactive visualisation and sight distance simulation into the design process allows the civil engineer to identify quickly whether the road geometry meets critical safety parameters related to sight distances, including grades, curvature, and visual obstructions such as barriers, beams and foliage.

Probably the most significant advantage of BIM compared with a drafting-centric process is the ability to extend the use of the information model beyond design, analysis and simulation into the field (construction) through solutions like Leica’s BIM Field Trip.

For example, transportation agencies increasingly are using the 3-D model for operating construction equipment with GPS (Global Positioning System) machine guidance.

Benefits include increased productivity and accuracy, reduced survey costs, lower equipment operating costs and an extended work day.
