BIM (building information modeling) is recognized today as one of the most important principles in projects that have adopted a new construction method.
BIM is a type of modeling, in which all the information about the building is included and presented as a complete design. With BIM,
all project activities are well-coordinated, which significantly reduces drawing errors, schedule delays, and costs.

Building
This section is dedicated to construction. In this section, Cad software is used for design, which has many applications.
In more complex steps, we need programs with more flexibility, which is solved with BIM.
The main difference between a BIM model and a 3D CAD model is that it stores important design information in all its details. BIM is basically a CAD model that connects to a database so that any project-related information can be stored in it; BIM therefore acts as a shared source of information between the entire building design and construction team. The result of this information integration is increased coordination, reduced errors, and ultimately increased quality of work.

Information
Undoubtedly, information constitutes a major part of BIM. Today, buildings have a more complex structure than in the past, which puts a lot of pressure on contractors due to the customer’s request for short delivery times and cost savings.
Today, building design has benefited from more services, among which BIM has an important role in these changes.
Most of the drawings are not in harmony with each other due to their multiplicity, etc. This issue needs to be further investigated and controlled in order to significantly reduce the existing errors, which is possible with BIM.
In fact, BIM allows you to coordinate all the information in the best way to have a good view of the project.

Modeling
Modeling is what many know as BIM. But is it right to turn all designs into 3D space? Somewhat yes.
BIM produces 3D models, but you can also work with 2D space. The designer can include the location of the room, walls, doors and furniture in his two-dimensional design without worrying about the heights of the objects. Finally, when these things are done in the best way, the views and sections of the work are formed, and this is where the three-dimensional space is considered.

Basic concepts in BIM Basic concepts of BIM

technology with building information modeling or BIM as an emerging technology, which in recent years in Iran and the world as a hot scientific discussion in the design, construction and operation of construction projects is talked about. This technology or knowledge has been considered by design, construction, studies, investment teams and all those involved in the construction industry, which in most countries has become the rules and requirements for the design, implementation, delivery and operation of projects.

In Iran, laws have been approved in the form of the Beam Technology Vision Document, and soon we will see the voluntary, incentive, and finally mandatory use of Beam technology to start projects.

BIM Beam, as an emerging knowledge around the world, strives to create integrated collaboration in the form of producing a multidimensional information model in order to increase the quality and reduce the time and cost of projects.

Basic concepts of BIM technology and familiarity with the details of these concepts is very important to avoid mistakes. One of the important issues in BIM technology is to use a tool of this knowledge in the form of software names and mistakenly Or describe a set of software. Software such as Revit Viewer, Archicad, Tekla Structures are just one tool or solution in Beam technology.

Bim technology is a set of processes and solutions along with tools such as software, hardware, Internet, etc. that can produce an information model for us, also this information model can be very practical and effective and we We can use them as an optimal model for the construction industry.

The use of BIM or Building Information Modeling technology helps us to design and produce higher quality projects, spending less time and money, which leads to long-term exploitation by the next generation of the project. There are a wide range of concepts in beam technology, all of which are essential to understanding, learning and entering beam technology.

Information integration or Bim integration

Beam is the technology of integrating information between studies and design, construction and operation. That is, producing a multidimensional model with information, along with geometry, that can execute and ultimately exploit information from design so that we can create integrated information in projects.

Start a BIM collaboration

To enter the production of an integrated information model, we must be able to establish a coordination in the sharing of information in the form of teamwork between team members, which is called BIM collaboration. BIM collaboration is a start for Bim integration and achieving the necessary integration in BIM technology.

One of the common problems in projects is the lack of integration and coordination and teamwork between project stakeholders. Using BIM technology, we can control and correct this current coordination and weakness of projects.

In all large and small projects, due to the importance of three factors of quality, time and cost, special attention has been paid to Bim technology and its solutions all over the world. In most countries of the world, Beam as a requirement and Coercion has been used in design and construction projects, and in Iran it will play a role in the coming years as an obligation and coercion in projects, hence the advance and familiarity with technology that in the coming years as a Coercion will be essential for any designer or building engineer.

In many projects, especially public projects such as hospitals, offices, schools, hotels, etc., it is very important to pay attention to the maintenance dimension or the seventh dimension of Beam technology.

It is noteworthy that BIM technology, by producing a comprehensive integrated model in the project from all sub-branches of design and construction, examines the project elements together according to the information produced, and ultimately minimizes design and implementation errors. Also, by updating the implemented models according to the implementation or production of the build model, we can advance the project to the stage of FM maintenance or Facility Management.
