How Bim Impriives Safety 3 From 5

By dynamically connecting design, Analysis, and documentation in a BIM workflow, most of the effort in  roadway design project is shifted back into the detailed design phase when the ability to impact project performance is high and the cost of making design changes is low.

This allows engineers to spend more time evaluating what-if scenarios to optimise the design and less time generating construction documentation.

Machine guidance applications can benefit significantly from a BIM model, an object based model supports attribute meta data associated to work packages for specific machine types. High accuracy paving machines require parametric models, while earthmoving machinery can work will with surfaces, string-Iines as well as parametric models.

Benefits in civil design

The most immediate benefits of BIM in the case of road and highway design are better designs and increased efficiency and productivity.

Because design and construction documentation are dynamically linked, the time needed to evaluate more alternatives, execute design changes and produce construction documentation is reduced. significantly.

This is particularly important for transportation agencies because it can shorten the time to contract letting resulting in projects being completed sooner and within more predictable timetables.

Beyond efficiency and productivity, BIM facilitates roadway optimisation by including visualization, simulation and analysis as part of the design process.

Many criteria can be assessed to achieve an optimal roadway design, for example in terms of constructability, road safety and sustainability.
