What is BIM BIM, or Building Information Modeling, has its roots all the way back to the 1970s and 1980s, but gained momentum in the construction industry in the early 2000s. Before BIM, people used traditional drawings and CAD models, but these were limited in how they handled their information, especially when it came to collaboration between different disciplines.
What is BIM
BIM, or Building Information Modeling, has its roots all the way back to the 1970s and 1980s, but gained momentum in the construction industry in the early 2000s. Before BIM, people used traditional drawings and CAD models, but these were limited in how they handled their information, especially when it came to collaboration between different disciplines.
By introducing standards for digital objects, it was easier to collaborate across borders between architects, engineers and contractors, thereby increasing the efficiency and precision of construction.
It also became easier to meet all the different regulations and requirements placed on finished houses and buildings. Since all digital models are finished representations of their physical counterparts, it became much easier to be able to show and sell premises, buildings and apartments even before they were completed.
What data does a BIM object contain?
Digital representations of products and materials that are used in various constructions and interiors. In addition to 3D geometry, the object contains technical data, specifications and certifications.
Geometric data
BIM objects contain a large amount of data, some of which is the shape of the object itself. Often, both 2D and 3D representations are included, such as dimensions and space requirements for installation and maintenance.
Non-geometric data
Here we find data about the product’s properties that have nothing to do with its shape.
- Product information: Manufacturer, retailer/wholesaler, and product specifications.
Performance characteristics: Environmental impact, U-values, and other characteristics that can affect the performance of the material/product. - Installation and maintenance data: Assembly instructions, maintenance frequency, and what tools are required for assembly.
- Cost data: Material costs and price details.
- Material properties: Colors, textures, and material types.
What is the purpose of BIM?
To create conditions for collaboration between different disciplines, companies, and work groups. The developer can see the finished building in 3D before work begins, how different materials interact, and which interior design is suitable. BIM objects help with everything from material properties to optimizing the design for different conditions.
Improve collaboration and communication
BIM looks the same to everyone who uses it, regardless of whether you are an architect, engineer, or interior designer. You just use different types of data linked to exactly the same object. The architect can draw up an object with a frame, material selection and exterior design. The engineer then takes over the file and ensures that the materials work together, runs internal wiring, and insulates it appropriately. The developer takes over and builds according to the drawing. Any questions that arise along the way are quickly and smoothly addressed based on the shared drawing.
Increase accuracy and reduce costly mistakes
The detailed technical information makes it possible to detect potential problems early in the process, instead of having to “redo, make it right” when the building is almost finished.
Improve energy efficiency and sustainability
With simulations and analyses, you can also measure everything from ventilation to energy use and environmental impact for the finished building very early in the process.
Streamline operations and maintenance
Even after the building has been completed, BIM is of great use for the operation of the property. Since all data about the manufacturer, function and operation is saved in the BIM object, the operations technician can easily and smoothly follow up on various problems and sources of error that arise over time.
Visualization and decision-making
Because BIM models provide a realistic and detailed picture of the finished building, everyone around can get a clear understanding of the project already in the planning stage.
Advantages of BIM
It creates opportunities to improve design, save money, improve safety, and reduce the impact on our nature.
Who uses BIM?
BIM can be used at almost all levels, from the architect and urban planner who starts sketching out the structure, size, materials, and exterior design to the private individual who is going to decorate their new bathroom and takes a virtual tour of what will become the new bathroom.
The drawing stage
In an office somewhere in Sweden, there is an urban planner who is thinking about how he can plan the new city district that is to be built. Most likely, he starts by creating basic models in a CAD program. As the project develops, he switches to a BIM model, where buildings, materials, and installations are defined in more detail with information about function and properties.
A little further away, in another office, sits a contractor who has been asked to build a couple of houses in a block. He receives the file from the urban planner and states that he can take on the project and contacts an architect who helps him design the buildings with different materials and appearance. The file then goes on to the engineer who makes sure that the architect’s vision is feasible and will withstand the stresses required, as well as optimizing the ventilation, electrical, and water systems.
When everyone agrees, the file goes on to a building permit officer who makes sure that the building meets all criteria and approves the construction for construction to begin.
The construction stage
The client then sends the file to the project manager who sets up a plan for the work and is responsible for ensuring that it meets the deadlines and that everything is done in the right order. Using VR glasses, he can navigate through the BIM model and check that water pipes and other installations are correctly placed before they are built. Even on site, workers can use digital models to double-check installation instructions in real time.
Maintenance and service
Just as the builder could follow the work, both on site and virtually, the end customer, interior designer or property owner can use BIM to check electrical and water lines before drilling into the wall or renovating their bathroom. Being able to go in and get installation and service instructions can save a huge amount of time for service technicians and property managers when problems arise.
BIM in bathroom design
Many have started to use professional designers when remodeling their bathrooms, and this is where BIM objects can really help visualize the finished bathroom!
Technological development and visualization
VR (Virtual Reality) and AR (Augmented Reality) provide the opportunity to experience a bathroom before it is built. Customers and designers can “go in” the bathroom virtually, test different material choices and layout options, and identify potential problems before production begins.
Digital twins are becoming increasingly common in the construction sector, where an exact digital copy of a bathroom can be used to monitor and analyze its function over time.
AI and automation in bathroom design
Layout optimization: AI can analyze the size of the room, water connections, and user needs to suggest the most efficient placement of sanitary ware and furniture.
Material selection and sustainability: By connecting AI to databases of material properties, the system can suggest environmentally friendly and sustainable materials based on the customer’s preferences and budget.
Automated clash detection: BIM software with AI functionality can identify clashes between installations, such as plumbing and electrical wiring, already in the planning phase.
More efficient collaboration and installation
Supplier integration: Bathroom product manufacturers create BIM objects with precise specifications, making it easier for architects and contractors to select products that fit the project’s requirements.
Minimize installation errors: BIM models can be used directly on site via mobile devices, ensuring that craftsmen assemble products according to specification.
Sustainability and energy efficiency
Water and energy consumption simulation: BIM can be used to analyze and optimize water flows, sewage solutions, and energy-efficient lighting.
Lifecycle management: By storing data on the lifespan and maintenance needs of materials, property owners can plan service and replacements more effectively.
BIM: A tool for the future
With BIM, VR, AI, and digital twins, bathroom design is entering a new era. From visualizing bathrooms in detail before they are built, to optimizing water consumption and energy efficiency, BIM makes it possible to create better solutions right from the start. The bathrooms of the future are not only more beautiful and more functional – they are also smarter and involve every step of the process.
