What is BIM?

Building information modeling

Although based on conventional 3D modeling techniques, BIM is the “intelligent” evolution of the classic 3D model. The BIM model not only includes simple geometric information on construction elements and components, but also all documents and data necessary for the technical and economic management of the project.

BIM is changing the construction industry

During the last 30 years, design (in its many aspects: architectural, engineering, installation, landscape, etc.) has experienced a real revolution in the construction industry, and new approaches as well as innovative operative tools have been developed. From computer-aided design (at first in 2D and later in 3D) to parametric design for objects (at first at a quantitative and later qualitative level), innovations have brought about a deep change in the way of conceiving a building project, its execution and its management stages. The result is the BIM, Building Information Modeling that can be shortly defined as an integrated model for construction work (building, infrastructure, etc.), which includes all data covering all aspects of its creation; in practice it is a completely new approach to the execution and management of construction work. Here architectural, structural and installation designs, features and properties of materials, components and systems, planning of execution stages, schedules and execution costs, as well as maintenance works are regarded as a whole, as parts of a single process where the entire product life is taken into consideration to reduce mistakes and optimize execution, checking and monitoring.

What is exactly the Building Information Modelling?

BIM is a dynamic set of procedures, processes and technologies that generate an interactive methodology to manage the design of a building and the data of a project in a digital format throughout the whole life cycle of the building’s life

BIM methodology was first theorized by Phil Bernstein and then made popular and standardized by Jetty Laiserin. The BuildingSMART Alliance, which is an international authority that regulates BIM, defines the concept through three main functions, which although different are linked to one another:

  • Building Information Modelling grants control of the process for the creation and use of data to manage the construction; design and build of an edifice throughout its life cycle. BIM allows all the members involved in the project to have simultaneous access to the same information, due to the interoperability among the technological platforms.
  • BIM permits the digital portrayal of the physical characteristics and complex structure, which comprise a building system. As so, it functions as a shared source of knowledge for information on a construction, in this way it creates a reliable foundation for decisions during the life cycle of the project, from the concept idea to the disposal.
  • BIM assists organization on a policy level and-the control of the different process in the business using information in the digital prototype to put into action the exchange of information during all phases. The benefits compound the central and visual-communication, sustainability, the preliminary exploration of options, efficient-design, control and more.

The application of BIM technology has a direct or indirect influence on all stakeholders-within the architectural, -engineering-and-building sector. BIM is an alternative method to using, creating and sharing data in construction.

It is possible to define BIM as the technology of modelling and associate processes to produce, communicate and analyze a building model that is characterized by the following aspects:

  • The construction components are represented as digital parametric objects that combine the graphic representation and data attributes, identify in different software parametric rules that permit them to be manipulated in a smart way;
  • The components include the data that describe the behavior throughout the analysis or processes of work.
  • The data is coherent-and non-redundant. Editing is shown in all the parts of the components and all the composition of which it is a part;
  • Data and components refer to a single common database, so that the information is always up to date and the risk of error is lowered as much as possible.

STR Vision CPM

STR Vision CPM is a full BIM software: it integrates the 3D model project with information about tools, facilities, human resources and all the parts you need in order to complete the job. You can control and manage the technical and economic information, both forecast and consumptive data, during all the project phases.
