The slogan BIM (Building Information Modeling) appears more and more often in the minds of investors, architects, building managers or computer software design vendors. There is not really a single definition of the word BIM, moreover, attempts to translate the English definition into Polish often lead to misunderstandings. The effect is that everyone talks about BIM, but there is no common definition. Many designers often use only a small part of BIM possibilities, a large part of software producers boast of the possibility of using BIM, which in fact is not possible.
It is a set of digital information for a planned or existing facility that contains all information about individual building components. The created three-dimensional model of the building contains a number of parameters that have assigned information about a given element of the object, e.g. walls – have dimensions, material – penetration coefficients, fittings – valve diameter, manufacturer, setting, access field. The model created at the design stage is later used by the contractor, investor and available to the future building manager.
98% of investments are completed late. The investment budget is often exceeded. As we live in a reality where time is a key value, the design phase cannot last too long. Traditional design tools, with limited time, often do not allow for the creation of a good quality design for all industries. Often, projects are not properly coordinated, contain errors in bills of quantities and in schedules, and the projects do not contain the necessary data for the contractor, which consequently, only at the implementation stage, has to resolve conflicts and read the documentation prepared in 2D, without sections or with an insufficient number of sections. This causes assembly delays and financial losses. BIM solves this problem. The model is coordinated before the end of the project, and the clashes are checked by external software and the occurrence is eliminated by designers. The three-dimensional model facilitates the contractor's work and allows at any time, anywhere, to create cross-sections or 3D views of the currently installed installations. In addition, the BIM model greatly facilitates future building management, which can be based on one common file, without the need to collect hundreds of separate drawings in several binders.
