How has BIM changed Façade Modeling?

Designing Drafting Services

Facade BIM Services fabrication is cross-disciplinary in the AEC industry and has roots in manufacturing. Architecture’s artistic pursuits, urban infrastructure’s emergence, and high-rise buildings’ emergence have given façade design technology and opportunities for its development.

BIM changes in facade BIM modeling          

Architects are responsible for meeting energy-efficient, sustainable building requirements, resolving cost estimation issues, and finding contractors when building or structuring a building. These are the criteria to be considered when constructing a building or structure. 

VR and CAD

Electronic drawings have replaced drawings used in the manual form due to the emergence of CAD. Consequently, conventional façade design methods have changed, and the field has been reshaped. It is not easy to manage CAD information. However, the integrated mode allows designers to share information in a common data environment, eliminating unnecessary transfers and implies the sharing of information databases. This eliminates excessive transfers and implies the full sharing of information.

3D BIM Services and Virtual Reality technology have allowed professionals to communicate more effectively regarding façade design. Through a 3D model, the architects could share ideas and focus on the volume of the facade and the exterior space. However, the lack of information data in construction and installation is a major drawback.


Besides BIM technology, Virtual Design and Construction is a new concept that provides designers, builders, operators, and maintenance teams with tools to construct parametric models and integrate building facilities and construction processes to achieve the project’s overall management objectives.

From ideation design to modular construction, VDC allows data to be reused and captured from conceptual design to prefabrication. The implementation of VDC relies on BIM technology. The field of façade design is closely related to BIM. Using it, you can design visuals, coordinate with multidisciplinary teams, analyze panels, and estimate quantities.

Features of façade design changed by BIM.

The architectural design industry has become dependent on BIM technology. Several changes have been made to façade design modules, including:-

Designing parametrically

BIM parametric design allows the creation of different buildings by changing facade algorithms and panel shapes. The parametric calculation, data statistics, and stimulation are all involved in Facade BIM Services fabrication components. The façade design model includes features that impose 3D geometry properties and other characteristics, like material and thermal performance.

Despite the different design parameters present in a façade design component, it can perform quick analyses and calculations on modeling, layout, evacuation, etc., and prioritize projects based on their importance. BIM parametric design differs from other parametric designs due to the geometric modeling feature.

The concept of parameterization differs from the concept of parametric design. In BIM software, parameterization refers to generating parametric designs based on modeling capabilities. For accurate BIM components, parametric design software must provide precise BIM capabilities. Building components’ levels of detail (LOD) determine the efficiency of BIM models that lay out the design details. This system works within the construction project and ranges from LOD 100 to LOD 500. For a façade design model to apply to the fabrication model, it is necessary to incorporate LOD400.

Visual design knowledge

The use of 3D BIM models facilitates the transfer of design information to construction professionals, enabling effective, efficient communication and preventing economic losses. Different façade design structures can visualize through 3D BIM models, such as panel edges, holes, junctions, and trims. By identifying and resolving conflicts between disciplines, design quality is improving.

Models that are part of a BIM have multiple views of sectional and technical drawings that provide information to other disciplines. While the designer modifies a component, all the views automatically update.

Professionals automatically correct them.

Once the main structure is complete, electromechanical engineers can collaborate with the façade designer. It allows for automatically integrating different disciplines and switching operating modes to identify and resolve modeling clashes.

Construction BIM benefits

In my opinion, the following are the top five benefits of BIM in construction:

Efforts are made to improve coordination and accuracy

Accuracy and coordination are the most obvious benefits of BIM for the AEC industry.

As a result of BIM, construction designers and engineers can coordinate more effectively, which leads to a better design and fewer surprises and problems.

The BIM process can help to accomplish this by assembling all systems and elements in 3D, verifying dimensions, detecting conflicts, and ensuring that components will fit together.

BIM helps visualize the construction process and identify potential problems ahead of time by creating a virtual construction model.

Cost and risk reduction

Construction projects stay on schedule and within budget using BIM to improve accuracy and coordination.

By reducing the need for rework – costly and time-consuming – BIM, for example, can reduce the likelihood of clashes between trades during construction.

The use of BIM for cost estimating also increases accuracy compared to traditional methods, which helps avoid overruns.

In addition, 4D simulations can assist project teams in identifying potential bottlenecks and understanding construction schedules better, again preventing costly delays.

Enhanced productivity and efficiency

It reduces the need for costly paper drawings and facilitates collaboration between stakeholders with BIM since everyone can view and manipulate the same model. As a result of BIM, professionals can also generate 2D drawings and schedules directly from 3D models, which saves them time and make their work more accurate. As well as designing and testing different construction scenarios, BIM can also generate simulations.

In addition, BIM has been proven to increase efficiency and productivity throughout the lifespan of a building.

A greater sense of sustainability

It is rare to discuss how BIM can promote greater sustainability.

We must find ways to reduce the construction industry’s impact on the environment since it produces a large amount of pollution and waste.

Digitally modeling waste problems and resources can help identify potential waste problems.

The use of BIM can also lead to environmentally friendly materials.

Using various thermal performance models, designers can use BIM to determine the most energy-efficient facade system.

Increasing sustainability in the built environment will necessitate using BIM as the construction industry embraces it as a priority.

Communicate and collaborate more effectively

BIM enhances communication and collaboration among all project team members, which is one of its most significant benefits.

Each team member uses different software programs and construction standards in the traditional design and construction process.

Team members sharing drawings or information can cause confusion and errors.

A team’s data can be found and shared easier with BIM because it uses a single integrated model that everyone can access. Doing this allows you to collaborate more efficiently and avoid mistakes more effectively. BIM can improve communication between all project team members and save time as a result!

BIM design modifications to processes

Delivery of model designs

The architectural industry places a lot of emphasis on model design delivery. It is possible to customize facade panel units in a project to expedite production. In a BIM façade design, data is not lost when transitioning from 2D to 3D fabrication models.

With accurate data transfer and digital fabrication, building quality can improve, and massive waste can reduce during the design and fabrication process, which could be a trend in the future.

Assembling virtually

As a result of centrally fabricated and assembled façade panels, the builders on the construction site have an excellent understanding of the different facade designs, heights, and types of facade panels. The data planning process assigns a unique code to material components in a BIM façade design model. For the creation of the material list, the façade model is made. Each component has a unique number.

The unit template arranges the numbers and units for the fabrication and placement of materials.


Facade BIM Services designers are successfully implementing 3D models with the advancement of BIM technology which helps them showcase building data, components, material fabrication process, and cost of materials and improves communication between disciplines.
