The idea of joint planning and construction of a building is not new: the first approaches to the implementation of the construction planning process using virtual building models emerged in the 60s of the last century. But only in the last few years, thanks to the computing power of computers and the growing interaction between people involved in construction, the topic of BIM has received a big boost. Building Information Modeling has evolved from a proof-of-concept stage to a practical method that increasingly affects the planning, construction and management of buildings around the world.
Building Information Modeling (BIM) describes the integrated process of planning, creating, constructing and managing a building. This is a data exchange idea based on standards and conventions. The central point of the method is the idea of a virtual and central building model (BIM model) that consists of various components (BIM objects). These components represent various building elements such as walls, ceilings, doors or windows. The building was almost designed and developed from the building model before its actual implementation.
BIM is often compared to simple 3D drawings: of course, 3D elements can be used to render a building model, however, the real added value of BIM lies in creating a construction process and an integrated planning program that brings everyone together who is involved in planning, construction and building management. and also improves the exchange of data at all stages of construction. The result is significant cost savings and time savings: mistakes can be avoided early on and the exchange of ideas and recipes is improved.
The exchange of data between project participants occurs or can be carried out using BIM objects. Characteristics and properties are assigned to each object . This allows you to evaluate a BIM object in a building model in several ways. These include, for example, determining weight and costs, planning maintenance and rehabilitation measures, or calculating key indicators for designing buildings in accordance with the latest environmental standards ( Green BIM).
Ideally, the BIM process covers the entire life cycle of a building. Depending on the phase of the process, the main users of BIM are different people / different systems. Depending on the user, the focus is on the various benefits of BIM.
The issues raised are certainly only a small part of the benefits that can be achieved through the use of BIM by manufacturers, owners, building services consulting engineers and general contractors. In an office or company, the implementation of a BIM process will lead to a significant optimization of all procedures.
