BIM is nothing more than the collection of all building data organized into a structure database easy to query both in a "visual" and a "numerical" way. BIM is the 3D virtual model of buildings. This model, however, is way more than pure geometry and some nice textures cast over it for visualization. A true BIM model consists of the virtual equivalents of the actual building parts and pieces used to build a building. These elements have all the characteristics - both physical and logical - of their real counterparts. To hire BIM service you can visit HCSE which is the best structural engineering company in USA.
