In the coming decades, it seems inevitable that architects will increasingly focus on renovations and rehabilitations –especially in established urban centers–, whether to modernize outdated structures or adapt to new uses and demands by contemporary society. A main challenge when executing these types of projects is obtaining a truly reliable working base, including accurate and true-to-life 3D models. Conducting surveys can be a herculean task, requiring extensive hours or days of on-site work and considerable effort to organize and interpret the collected information, often resulting in data that lacks adequate precision.
To simplify these processes, technological advancements have provided a solution: site surveys based on point clouds and 3D scanning, which have the potential to revolutionize the design process. Point clouds are collections of millions or billions of individual measurement points on the surface of objects, which can be obtained through laser scanners, drones, or 3D cameras. Each measurement point contains X, Y, and Z coordinates, as well as other optical properties (reflectance, color). Multiple scanning positions are registered (stitched) to create point clouds of an entire scene, which can be loaded into virtually any CAD platform for standard fieldwork.
The Leica BLK360 Imaging Laser Scanner is a product developed specifically for this purpose. It effortlessly captures the essence of any structure, from the most complex to the simplest. Its ability to capture intricate details makes it an invaluable resource in architectural projects, enabling the identification of all recesses, angles, reliefs, and everything present in the space, ensuring that architectural plans align perfectly with the physical reality of the project site.
The use of point cloud data translates into substantial cost and time savings. Accurate surveying minimizes rework, errors, and design changes during construction. It also contributes to reducing site visits, saving valuable time and resources during ongoing construction. This efficiency not only accelerates the project timeline but also minimizes interruptions at the construction site. Another advantage is the absence of the need for invasive explorations in the structure, which is very useful for restoration projects, and which often involves complex details. Point cloud data also becomes a catalyst for collaboration, providing all project stakeholders with a detailed and accurate representation of the site, and promoting effective communication and decision-making.
Case Study: Atelier Lumi - Maximizing Spaces with Scanning Technology
An example of the application of the Leica BLK360 is in the Atelier Lumi project, a 400-square-foot guest house that challenges its compact dimensions through a design inspired by Japanese small-house lifestyle techniques. Developed by architect Emma Pereira, the space features double-height ceilings, a raised bedroom, and the strategic use of windows and mirrors that create the illusion of spaciousness within a confined area. The distinctive composition of the space, with its intricate curves and angles, became the ideal canvas to showcase the tool's prowess. In less than 30 minutes, the entire apartment was captured in a highly detailed 3D model, a digital twin demonstrating the scanner's precision with errors of less than 4 mm.
As architects begin to embrace the era of digital twins and point cloud technology, the possibilities for precision, collaboration, and innovation in design become limitless. In addition to making work easier and enabling collaboration, this type of tool frees professionals from the burden of manual labor, allowing them to focus exclusively on the essential characteristics and qualities of the space to be designed. This evolution will not only redefine the practice of architecture but also promises to shape a future where creativity and efficiency intertwine with advances provided by technology and innovation.
