Any construction begins with certain planning. It is necessary to think about such components as budget, materials, people who will build, because planning will save time, resources and money. Importantly to make sure all building communications, MEP systems or Structural, are correlated with each other properly.
Some time ago this task was quite complicated and demanded the efforts of a large group of professionals. Human errors were not rare as well. Thus there were certain risks to do something wrong during the modelling process. Modern advances in graphics and design led to the creation of a BIM clash detection service.
With BIM coordination you could identify and solve design problems before they arise on the construction site. Also, you can mitigate budget and scheduling risks before breaking ground.
