A comprehensive BIM also includes maintenance data, project scheduling, costs information, and more. While 3D modeling is a part of BIM, and an important one, it is not just a replacement for previous types of 3D modeling like AutoCAD. The ability to share relevant data with all of the project’s participants makes BIM an excellent collaboration tool in general. OverviewīIM – Building Information Modeling – is a complicated process that includes not only 3D modelling, but also planning, designing, constructing, collaboration, and more. And, of course, while it is easy to do so with smaller projects – larger, more sophisticated construction projects would be having a hard time reaching the same level of cooperation without BIM software. It’s hard to imagine a construction project lifecycle without collaborations nowadays from contractors, engineers and architects all combining their efforts to achieve their goals from meeting client’s expectations, minimalizing the construction errors caused by miscommunication and so on. 22 AECOsim Building Designer (OpenBuildings Designer).
