Geometry processing in conception and construction of buildings

The talk will focus on the role of geometry processing in the conception and construction of buildings at different stages.

In the first part of the presentation, I will talk about the architectural conception stage of building design with some insights into the recent advancements in geometry processing focused on designing more cost-efficient structures with improved physical properties. Here, a crucial detail is the geometry of the underlying mesh-structure, which can impact the transfer of stresses acting within and on the structure, e.g., additional load from snow cover on a rooftop. In this context, I will discuss planar-hexagonal meshes, which, even if challenging to design, have many interesting properties that are sought after in architecture.

In the second part, I will discuss the role of 3D geometry processing in quality control and progress monitoring during the construction phase. Firstly, I will introduce H2020 BIM2TWIN Project, which aimed to providing a comprehensive platform for digital twin technology of buildings under construction. In this part of the talk, I will then focus on the problem of object detection in the 3D point cloud data with respect to the BIM, as well as on the problems related to 3D point clouds acquisition in the context of construction quality measurements. Finally, I will address the most important obstacles faces during the projects, such as the quality of BIM and lack of public data suitable for studying construction sites from the point of view of progress monitoring and quality control. I will finish the talk by describing the ConSLAM dataset created in order to fill in the public data gap.


Kacper Pluta obtained his Ph.D. in Computer Science from Université Paris-Est, France in 2017 after defending his dissertation entitled: Rigid Motions on Discrete Spaces. Since September 2023, Kacper is an Enseignant-Chercheur (Associate Professor) at ESIEE Paris, Université Gustave Eiffel, France. Priori to taking the position at Univeristé Gustave Eiffel he worked as a research engineer on H2020 BIM2TWIN Project at Inria, Sophia-AntiPolis, France, and after finishing his Ph.D. was a postdoctoral fellow at the Technion - Israel Institute of Technology. Kacper's work spans topics from theoretical discrete geometry to 3D geometry processing applies to architecture and civil engineering. He also participated in studies related to geoengineering with focus on natural hazards such as landslides.
