Using Open BIM technology, BIMserver.center make it possible to implant a collaborative workflow to develop architecture, engineering and construction projects in an open and coordinated manner amongst all the technical specialists that make up the work team. In the Open BIM environment, projects are solved in a collaborative and progressive manner, as these are defined as the members of the work team establish proposals and solutions for all the aspects of the project. The main property of the Open BIM technology is that it is based on the use of IFC standard interchange formats. By using this format, which is standard and public, and not linked to a specific developer, the durability of the work that has been carried out is guaranteed, since it does not depend on the applications that have been used to carry out the work. Even the own data files of these applications, from a durability point of view of the project, are set aside as auxiliary files, because the IFC file that is generated provides the final information of the project.
