Benefits of BIM for Civil Engineers

 

BIM is mostly recognized in architecture and construction field but its usages are limited to civil engineering field. The civil engineers (who deal with roads & highways designs) are still very much unaware to reap the benefits of BIM completely. To some extent, it is used by civil engineers who perform with structural as well as architectural engineers on a regular basis.

 

Now the question is what benefits BIM provide to a civil engineer superior designs and improved efficiency and productivity. With BIM, the civil engineers will be able to decrease the time to a great extent necessary for assessing various alternatives, carrying out alterations as well as generating construction documentation as design and construction documentation are intensively associated with BIM. Consequently, any project can be finished quickly by maintaining anticipated time schedule. The roadway optimization is also improved with the inclusion of simulation, visualization and analysis to the design progression. The following two factors are vital to accomplish a best possible roadway design.

 

Construct-ability: Usually civil engineers create their design for code compliance, giving less importance to constructability. Belated schedules, change orders and RFI may occur after the commencement of construction, if design is executed imperfectly in the field owing to confusing documentation. While developing a new roadway construction project containing interchanges and bridges with an estimated budget of $100 million, almost 7 to 8 percent of it will be incurred in design development. If the design expense is minimized by 35 percent through a more productivity procedure, $ 2.6 million can be saved. However, if the construction part is decreased by 15 percent with construct-ability throughout the design progression, nearly $14 million can be saved.

Road safety: Normally, sight distance analysis is derived from mathematical equations addressing vertical curvature in the road profile. But, we often, do not include the factors like visual obstructions and horizontal layout by applying this method. So, civil engineers incorporate interactive visualization together with sight distance simulation into the design method because it facilitates them to recognize whether the road geometry congregates vital safety parameters regarding sight distance like curvature, grades as well as visual obstacles like barriers, foliage and berms.
