BIM - Building Information Modeling


What is BIM?


Building information modeling (BIM) is an ongoing process to generate, monitor and save physical and functional data for construction sites and building sites. Building information models (BIMs) are files (often but not always in exclusive formats and containing proprietary data) which can be extracted, exchanged or networked to support decision-making regarding a building or other built asset. Design and construction of roads and railways includes most often needs and work tasks to fit geometrically bridges into the roads. Compared to the traditional methods, BIM based modelling and construction process offer new advanced possibilities for this fitting work. Current BIM software is used by individuals, businesses and government agencies who plan, design, construct, operate and maintain diverse physical infrastructures, such as water, refuse, electricity, gas, communication utilities, roads, bridges, ports, tunnels, etc..


The simple process below describes the steps how BIM support in the building process

What is the main benefit of BIM?


BIM means that you not only capture reality but also maintain control of the data which improves the collaboration of divers entities involved in the construction process. BIM supports in looking at a project from the big picture but at the same time allows to dive into detail. The BIM toolset helps automate clash detection of elements such as electrical conduit or ductwork that run into a beam. By modeling all of these things first, clashes are discovered early, and costly on-site issues can be reduced. The digital model also ensures a perfect fit of elements that are manufactured off-site, allowing these components to be easily bolted into place rather than created on-site.  The advantage of prior simulation process saves money, time and resources.



Below you can see an example of the evolvement of data in the finish construction process. While in 1970 all drawings were still paper based – 35 years later 3D is the state of the Art for large scale construction development nationwide.




BIM founder and specialist Petteri Palviainen stipulates that “(…) it is just a matter of time until other countries will follow to use BIM as a mandatory tool in building and construction processes”

Watch this space - The next BIM article will show BIM advancements in other countries such as Vietnam and give a deeper insight how BIM is connected to open source data management programs such as “Infrakit” as well as give a major focus on machine control aspects of BIM.
