Since its beginning, 3D BIM has sparked a number of improvements in the AEC sector. One of the items on the list is conventional facade design, where the effects of technology can be seen throughout the entire process of designing, manufacturing, and installing a facade. The function of a building's facade design extends beyond protection. Also, it communicates with the outside world, represents the identity of the building's architecture, and supports energy efficiency. Traditional 2D drawings were replaced with 3D digital modeling through the use of 3D BIM modeling services and Virtual Reality technologies, where architects may interact and share ideas to create sophisticated, contemporary, and varied facades. With its integrated database, the system overcomes the drawback of withholding information. The shape, volume, and outside shape of a facade are important considerations for architects, and multidisciplinary collaboration and VR tools facilitate facade design, production, and installation.
How has the construction modeling of facades been altered by BIM?
- The facade, which is the portion of a building that faces the outside, provides a general overview of the complete structure. The facade design affects a building's acoustic performance, light transmission, energy efficiency, and interaction with the surrounding environment.
- With the growth of urban complexes, high-rise structures, and BIM technology, the scope of facade design grew. BIM addressed a number of requirements and issues encountered during the industrialization of facade design, including project management, data coordination from design to manufacturing, material waste, sustainability, etc.
- A coordinated facade design and building design with digital visualization were made possible by the conversion of the manual to digital drawings utilizing CAD and VR technologies. The synchronized architectural or facade drawings and shop drawings produced by the 3D model assisted in achieving the required level of building energy performance.
- Virtual design and construction (VDC) was implemented with the aid of BIM technology to help with project management. Data from the design phase to pre-fabrication was captured with the aid of VDC, which aids in the development of modular systems.
- Facade fabrication was able to tackle possible concerns from design through manufacturing while reducing waste. Thanks to 3D models and CAD drawings.
BIM's advantages for designing facades:
Facade design engineering evolved as a result of the use of BIM technologies. The BIM-based facade design element offered a number of benefits to a building's architecture.
- Parametric facade design: By transforming each component of the facade into a functional variable or algorithm, BIM makes parametric facade design possible. The diverse building designs get achieved by altering these facade algorithms in BIM. BIM parametric design offers parametric simulation, calculation, and pertinent data statistics for all the real properties of facade components. The geometrical characteristics of the virtual facade components also include things like component material, thermal performance, price, weight, and installation number. Facade parametric design makes a number of computations and statistical analyses for modeling based on various parameters. Additional criteria like energy conservation, layout, and evacuation are also assessed and prioritized in the model to produce an optimal facade design. A separate level of detail (LOD) is used by BIM to categorize the precision of represented architectural components. LOD 400 guarantees the usability of the facade design for plant fabrication.
- 3D virtual design using BIM:?BIM's 3D virtual facade design aids in the dissemination of design information and data to other project participants. The 3D representation provided by BIM provides a complete description of the facade design, including the joints at the facade panel edge, corner, hole, junction, and bottom flashing and trim of the beam. With the entity component data, BIM aids in the automatic generation of the multi-view sectional drawings and axonometric drawings of curtain walls. All modifications made to the component design of the facade are automatically updated. It saves the task of revising the plan, elevation, and sections. BIM Visualization and its related features help the design team communicate better, work more efficiently, and resolve conflicts so that the quality of the facade design is higher.
- Adaptive parametric design:?Designs are automatically changed in parametric modeling that is based on BIM. It results from the model's parameters and controlled sizes having a commensurate relationship. BIM enables the transformation of the geometric facade production model into building components with actual properties. Building elements are adjusted as a result of changing geometric model parameters. The usage of building components with real attributes enables the designing of a parametric curtain wall component library. The library is beneficial and is frequently used as corporate knowledge.
- Vertical facade design: The curtain wall or facade of a building is a component of both the mechanical fabrication and structural structures. From conceptual design to precise modeling, plant manufacture, and installation, the curtain wall is involved. Hence, there is a potential that some data will be lost. This disadvantage is overcome by BIM's top-down facade design methodology. It aids in creating accurate fabrications using correct design data and exact curved-surface modeling. The first step in the Top-down design method used by BIM is creating the design's "top basic skeleton." After various revisions and part requirements, a complete design layout is produced based on this skeleton. For instance, the tower, floor, and other components of the facade design engineering, which is the highest top fundamental skeleton, are separated. The geometric and spatial positioning of the facade panels is contained in the top basic skeleton developed for these parts. Due to their interactions and connections with the facade panel components, these top basic skeletons serve as the foundation of top-down facade design.
- BIM modifies the facade modeling process:?With the requirement for increasingly complicated facade designing and construction, BIM technology altered the facade modeling process. A few modifications made to the process of designing facades by technology are as follows:
- Models of facade instead of drawings: The facade panel units need a lot more modification than the standard facade panel production. There are numerous facade panels in a single project as well as various fa?ade designs for distinct projects. As a result, the use of facade models instead of drawings for design was made possible by the introduction of BIM technology. The translation of 2D drawings to 3D manufacturing models eliminates data loss. It precisely translates the fa?ade design data into the numerical control machinery needed to construct the facade. BIM facade models enhance the quality of buildings, while autonomous digital production minimizes material waste.
- Centre facade panels virtually assembled: The virtual assembly of centralized facade panels is made possible using BIM. Since it is done in workshops, the construction workers on site need to be familiar with facade panels (for various facades and different floor heights) in order to position them correctly. After a thorough BIM facade design has been created, individual codes are assigned to the fa?ade's unit panels, keel frames, and irregular profiles in accordance with data planning. The full building's facade model is then put together using the material list. Each component that is taken from the BIM model is given a special number by the material list. The facade panel's manufacture, transportation, installation direction, and sequencing are all created using BIM. The information facilitates the facade panel's virtual assembly, enabling multi-operational construction planning, installation sequencing, and quality improvement.
