“…This design is in 2D or 3D rendering. Experts must be able to read 2D drawings and assemble a reinforcement cage in 3D to place reinforcements in a reinforced concrete (RC) formwork [24]. After this step and installation, another important task before pouring the concrete in terms of static performance and construction is to check the position and dimensions of the formwork and reinforcements.…”

Progressive technologies and practices are shifting the possibilities of building design and improving work efficiency. Constantly changing site conditions require different procedures and designs that take into account these changing conditions, whether it is a design solution, a change in environmental conditions, or just sustainability factors. Adaptive building design offers opportunities to cope with changing factors to achieve the ähighest possible level of building quality. This case study deals with the topic of adaptive formwork design for building renovation, taking into account sustainability. The aim of the article is an investigation and demonstration of the building information modeling (BIM) environment used for the adaptive design of formwork elements for the building renovation in the context of sustainability. The object of the case study is a building in the center of Kosice, Slovakia. The BIM environment allows prompt and correct adaptation of the formwork design to changing lighting conditions, ventilation, heating and temperature during the design of the building.

Even when adherence to project schedule is the most critical performance metric among project owners, still 53 % of typical construction projects exhibit schedule delays. To contribute to more efficient construction progress monitoring, this research proposes a method to detect the most common temporary object classes in large-scale laser scanner point clouds of construction sites. The proposed workflow includes a combination of several techniques: image processing over vertical projections, finding patterns in 3D detected contours, and performing checks over vertical cross-sections. A deep learning algorithm was leveraged to classify these cross-sections for the purpose of formwork detection. After applying the method on three real-world point clouds and testing with three object categories (cranes, scaffolds, and formwork), the results reveal that the process achieves average rates above 88 % for precision and recall and outstanding computational performance (1 s to process 10 5 points). These metrics demonstrate the method's capability to support the automatic segmentation of point clouds of construction sites.
