What does building information modelling mean?



Building information modelling is the acronym for the English expression Building Information Modelling, which could be translated as modelling of building data.

This name is however restrictive since BIM concerns the entire construction universe and does not stop at modelling.

However, this concept remains difficult to define exhaustively because it is relatively a recent technology, the possibilities of which are constantly increasing.

Still, Building Information Modelling allows you to create virtual projects model of buildings in 3 dimensions, and that these models allow you to design, plan, create, manage and visualize each new creation before it even leaves the ground and until its destruction.

In the construction world, it's BIM that defines what to do and when to do it.

It is not limited to construction alone but encompasses the entire life cycle of a structure from its creation to its deconstruction and the recycling of its materials.

It is not limited to the building sector either but concerns the world of construction projects as a whole, including public work and civil engineering.

It is possible to structure, produce, manage and visualize a certain amount of data in order to create a model of a built structure and to predict, even before its foundation, how it can be repaired, destroyed, and even how its materials can be recycled.

We are pioneers in integrating building data modelling (BIM) and virtual design and construction (VDC) into the design process.

We constantly aim to maximize the considerable potential of this project delivery technology to foster a collaborative, effective, and efficient building and infrastructure design process.

This is the 3-dimensional representation of a building design, a model today.

It is difficult to find a definition of BIM accepted by all.

Building information modelling is above all working methods and a 3D parametric digital mock-up that contains intelligent and structured data.

BIM is the sharing of reliable information throughout the lifespan of a building or infrastructure, from design to demolition.

The digital model is a digital representation of the physical and functional characteristics of this building or the infrastructures.

We use the technology and work processes associated with BIM to collaboratively design buildings, infrastructure elements, and even cities.

All project data is thus, integrated into a single 3D computer model, which can be accessed by various interested parties.

The model can contain all of the physical and functional characteristics of the project, including structure, geometry, aesthetics, materials, systems, and dynamic performance.

The 3D model becomes 4D if we associate it with a time dimension and 5D if we add the information related to costs.

Building information modelling is often equated with software or technology projects.

It is much more than that. It is in fact a series of processes or working methods used throughout the design, construction, and use of a building.

Building information modelling defines who does what, how, and when.

One or more intelligent and structured parametric 3D virtual models are used throughout the design, construction activities, and even use of a building.

These virtual models make it possible to perform analysis and simulations (energy, structural calculation, detection of conflicts, etc.), checks (compliance with standards, budget, etc.), and visualizations.

The structured digital model allows collaboration between all the stakeholders in a project, either through data exchange or by allowing intervention on a single model.

With Building information modelling, analysis-controls-visualization are carried out very early in the study of a project model, thus allowing a better design quality and the detection of problems before the start of construction.

Thanks to the constantly updated digital model, construction costs are better controlled because they are extracted in real-time.

The quality of the buildings is generally improved thanks to the various analysis and simulations carried out at an early stage of the project before the costs of the modifications have too much impact.

Building information modelling is not software or a brand of software, however, a so-called BIM application capable of modelling a digital realistic model made up of parametric objects is necessary.

However, the use of non-parametric 2D or 3D programs is perfectly possible in BIM design processes, for example for the production of paper plans, the sharing of information with stakeholders without BIM software, or during the pre-phase. -project.

Why Building Information Modelling?

Building Information Modelling | bims | redfibre
The use of building information modelling in the world of architecture and construction more generally offers many advantages.

In terms of budget reduced costs, material costs as well as implementation, Building information modelling opens up many perspectives on the future, since it makes it possible to test and directly analyze the construction project of a building.

The 3-dimensional representation makes it possible to visualize, plan and estimate risks in real-time.

The budget is better controlled since the costs are reduced per square meter in new buildings.

Another advantage of building information modelling:

Building Information Modelling | bim modelling | redfibre
Ease of communication. In the construction industry world, trades intersect and collaborations can quickly become a real headache.

However, with building information modelling, all information can be added to the common project, which facilitates the understanding of the different actors.

Thanks to this technology, buildings are better heated and better conditioned, better protected, more respectful towards the environment, and all of this at a lower cost.

BIM, or Building Information Modelling, is a concept for structuring and visualizing data and a digital model of a built structure. But what exactly is it and how it is used on a daily basis?

How does Building Information Modelling work?

Building Information Modelling | models to build | redfibre
The essence of the Building Information Modelling working method is to allow the creation of virtual 3D models that can be explored and manipulated by all in a construction industry project, thus facilitating the understanding of the relationships between spaces, materials, and systems of a structure or a building.

The workflow insight goes like the database generates a 3D image and creates construction plans of a structure.

The building systems BIM process makes it possible to create, visualize and test this structure (or a building) in 3D, over its entire lifespan.

The detailed data thus makes it possible to better manage the detection of conflicts and costs.

It also enables better design decisions to be made and the coordination of construction, improved construction performance and better collaboration throughout the project.

Building data modelling (BIM)

Building Information Modelling | data modelling | redfibre
A building information model (BIM) is a digital representation of the physical and functional characteristics of a building used in the industry field.
It is a source of information shared through the life cycle of the building a common data environment, from design to demolition beneficial for users.

The fundamental principle of Building information modelling is the collaboration of the various stakeholders involved in one or other phases of a building's life cycle.

Building information modelling is not just about using software or coordination or applying a particular way of working in the field.

It's another way of looking at building management that optimizes the working time and avoids costly mistakes.

The worldwide success of this process lies in an efficient organization of the work.

Overview on how to set up BIM for organizations?

Building Information Modelling | Bims | redfibre
The BIM process supports the creation of intelligent data that can be used throughout the lifecycle of the building or infrastructure construction industry project. Here are some steps and parameters that we need to implement on the road to a successful setup.


Planning

Building Information Modelling | bim modelling | redfibre The project team makes better decisions by combining reality capture (terms of dimensions) and real-world data to generate contextual models of the existing urban and natural environment and solves all the issues,.


Design

Building Information Modelling | models to build | redfibre
The stages of the design phase, analysis, knowledge execution, and documentation are carried out during this phase by the design team, basically the designers. The pre-construction process begins with the use of BIM data for planning and logistics purposes by construction professionals.

Construction

Building Information Modelling | models to build| redfibre
During this construction management phase, basically, the construction stage, the realization begins with the exploitation of various BIM data for an optimization of the construction phase within particular the 4D data les (time), Digital representations or virtual information model les, building plan models les, and structures as well as the 5D (quantities) extracted from the business models les for more speed, efficiency, and savings which also help construction management.


Operation

Building Information Modelling | bims | redfibre
Building information modelling data workflows are continue to be used for equipment operation and maintenance. The benefits of it are that they can be used later to renovate or deconstruct at a low cost for the industry.

Data modelling refers to the formalization and documentation of processes and events that occur during the design and development of applications.

Data modelling techniques and tools collect designs from complex systems and translate them into simplified representations of processes and data flow to create a model for construction and re-engineering.

A data model can be compared to a diagram or a flowchart that illustrates the relationships between data.

Collecting all the possible relationships in a data model can be time-consuming, but it's an important step that should not be rushed.

Well-documented models help identify errors and make necessary corrections before writing code.

Modelers often use multiple models to represent the same data and ensure that all processes, entities, relationships, and data flows have been identified. Data modelling includes several approaches:

Conceptual data modelling helps identify the highest level of relationships between different entities which helps the future of construction planning.

Enterprise data modelling is similar to conceptual data modelling but helps meet specific business needs.

Logical data modelling specifically illustrates entities, attributes, and relationships involved in a business function. It serves as the starting point for the creation of the physical data model.

Physical data modelling is the application-specific and database-specific implementation of a logical data model.
Develop your global vision of the building information modelling process to successfully implement it.

Why is BIM management important?

Building Information Modelling | bim modelling | redfibre
According to United Nations estimates, the world's population is expected to reach 10 billion people by 2050.

The global architecture, engineering, and construction sectors are responsible for the creation of spaces and places of life for the population.

In addition, the owners and project managers are responsible for the management and maintenance of these assets.

The sector must find smarter and more efficient design methods to design and construct buildings, not only to meet global demand but also to create more pleasant, sustainable, intelligent, and more economical spaces.

Building information modelling management not only allows design and construction teams to work more efficiently, but also to capture the data they create in the process to improve their management and maintenance.

BIM data can also provide information about planning and resource management at the project, city, territory, or country level.

This is the reason why the use of BIM is becoming compulsory all over the world, especially in public markets.

What are the advantages of building information modelling?

Building Information Modelling | bims | redfibre
The BIM process makes it possible to design and document building and infrastructure projects.

All the information about buildings and infrastructures is modelled and entered in the BIM.

The model can be used for analysis purposes to explore different variations of projects and also allows visualizations to be created to better understand the building before it is constructed.

The model is then used to generate the project documentation for its construction.

Why Building information modelling?

Building Information Modelling | models to build| redfibre
BIM or Building Information Modelling is an intelligent process based on a 3D model that provides architecture, engineering, and construction professionals with the information and tools necessary to plan, design, build, and manage more efficient buildings and infrastructure.

Building information modelling is ecological

Building Information Modelling | bim modelling | redfibre
The time saved, thanks to BIM allows us to save energy and save costs. Its use also avoids wastage of materials during construction and during operation of the building.

BIM could even prove useful, eventually, to achieve sustainable demolition. In addition, energy modelling performed with BIM can help limit energy consumption throughout the useful life of the building.

Here are deliverables related to BIM technologies:

Added value at each stage of the project

We employ Building information modelling during various stages of the project lifecycle; from design to construction, then an operation to sustainable demolition.

A higher-level application of BIM technologies provides better risk management, significant productivity gains, shorter construction times, and significant savings over the entire project lifecycle.

As the design and construction plans take shape, the team can analyse various solutions, spot any problems or difficulties, and fix them before they actually happen.

This way of doing things reduces risk, in addition to saving time and money.

Make good decisions faster.

Building information modelling enables a continual exchange of information between architects, engineers, specialists, developers, contractors, companies, and other stakeholders. It promotes informed and faster decision-making by the team and ultimately contributes to a more efficient and effective design, than if it had not been used.

The use of BIM technology allows us to help the owner make decisions earlier in the project design process.

The engineer, for example, is thus able to more adequately determine the actual dimensions and capacities of the equipment.

Previously, we had to add contingencies of around 25% in equipment, in anticipation of changes made late in the design stage.

By making decisions earlier, we can establish the dimensions more precisely, leaving the building owner with more space to rent or sell.

Building information modelling is also used for the detection of conflicts and interference, for example, in the event that the electrical and other plans both indicate installing equipment in the same space.

Other applications make it possible, in particular, to test different scenarios, such as the operation of the emergency ventilation system, and to perform energy analysis and modelling.

It is also possible, using BIM, to simulate the movement of the sun in the sky for daylighting studies and optimization of the solar panel system.

The faster response to design changes

Building Information Modelling | bims | redfibre
During the construction progress phase, BIM speeds up the response time to changes in plans or site problems.

It helps with planning and cost management.

Our teams use Building information modelling to assess constructability, develop and communicate work scheduling and contractors' programming, produce material lists and quantities, as well as establish the schedule and logistics for material delivery.

Owners and operators also have the option of using BIM technology to improve the efficiency of their building management, such as planning and tracking maintenance activities, performing renovations, or carrying out the demolition.
