Challenges and benefits of 3D modeling in construction
The digital revolution has changed the world of construction: 3D modeling is a good example. This technology makes it possible to reproduce an object in virtual form, greatly simplifying the construction process. But how does it work in practice?
A reminder: what is 3D modeling?
Generally speaking, 3D modelling refers to the virtual object creation
using specialized software. 3D modeling software, sometimes called CAD (Computer-Aided Design) software, is a tool for creating, manipulating and modifying 3D models. By virtually sculpting shapes, adding textures or simulating lighting, these programs can produce highly realistic visual renderings. 3D software also plays an essential role in the
3D printing
3D design has many applications in the construction sector, with BIM(Building Information Modeling): this technique consists of designing and representing construction elements in three dimensions, using 3D files. These can be buildings, infrastructures or components. BIM can be used to create digital models of buildings as well as detailed designs of mechanical parts.
3D modeling to meet the challenges of construction
The level of complexity
Construction projects tend to become increasingly complex, with sophisticated designs and precise requirements. 3D modeling helps us to better understand these conditions by visualizing the project's contours in detail - thus considerably reducing the risk of making sometimes costly mistakes..
Interdisciplinary coordination
In each project, many disciplines work together: architecture, structural engineering, electronics, plumbing...
3D modeling helps to better understand how the various stakeholders work together upstream of the execution phase.
Sustainability and energy efficiency
3D modeling software can be used to simulate and evaluate the energy performance of buildings, and thus estimate their environmental impact, even before they are built. They can also be used for facility management, maintenance and renovation of existing buildings.
This encourages the design of more durable and energy-efficient structures, in line with current environmental concerns.
Regulatory compliance
3D models have the advantage of helping teams to ensure that every project complies with current standards and regulations - whether local or national. This reduces the risk of legal problems and delays in approval processes.
The benefits of 3D modeling
In general, 3D modeling helps optimize the productivity of any project team, whatever its size.
Realistic and enhanced visualization
3D software can be used to create virtual representations of construction projects, as realistically as possible. They enable you to visualize the final design even before construction begins.
The 3D model generated helps those involved to better understand the building's appearance and functionality, reducing the risk of design disagreements.
Early detection of errors
With 3D models, any potential design errors can be spotted quickly and easily before construction begins. Problems can then be dealt with immediately, avoiding the additional expense of late modifications. This saves considerable time and money.
Optimized design
3D modelling makes it easier to explore different design options available. Stakeholders can test and analyze several alternatives, to find the solution that suits them best in terms of fluid network integration, energy efficiency, cost and sustainability.
Better collaboration
The use of 3D modeling facilitates exchanges between the various parties involved in the project.
Visit customer communication is facilitated. They can visualize their future property and express their preferences, which tends to improve their overall satisfaction and reduce the risk of disagreements during the construction phase.
Collaboration between teams is also facilitated. The multiple trades involved in the project (architects, engineers, energy consultants, design specialists, etc.) can work together on a BIM collaboration platform. They benefit from better coordination and deeper mutual understanding.
Training and awareness-raising
3D models can also be used to:
train workers (safety procedures, construction methods, use of equipment, etc.);
raise public awareness of infrastructure and urban development projects.
Last but not least, creating 3D models is very useful for the regulatory communication.
They enable project details to be shared with the relevant authorities, making it easier to demonstrate that the project complies with current standards. In short, 3D modeling is an important asset for the construction industry, not least because it facilitates communication. Thanks to immersive visualizations and real-time tracking of modifications, the parties involved in each project collaborate more effectively.
