Robotization is a term frequently used in particular with reference to the car industry. With the development of service robots, however, we may expect that these technologies will be increasingly applied in construction as well. The objective of this paper is to map the state of the art in automation worldwide presenting some solutions for use in the building industry.

The article is aimed at the description of design, 3D modelling and simulation of technology for processing and fabrication of the formwork for complex concrete structures. The process of fabrication of complex-shaped elements from the special composite concrete mixture with application of several sophisticated software, technologies and industrial robot KUKA Agilus is also described in this work. The RHWC (Robotic Hot Wire Cutter) technology fully matches the prior aspects of the Industry 4.0 concept. The study consists of four parts. The first part simplified describes the mathematical apparatus of parametric modelling for complex concrete surfaces in Rhino 6.0 software. During the research two figures was precisely designed and modelled. The second part is aimed at the description of contemporary architectural trends in complex concrete structures manufacturing, modelling and analysis of ability to implement the complex-shaped surfaces with the RHWC technology. The third part describes the materials for technology. Expanded Polystyrene foam was chosen as the optimal material for the fabrication of formwork for complex-shaped concrete structures for its cost, weight and processability, as well as the special composite cement mixture which fully met all the requirements for its fluidity and smoothness. The fourth part is demonstration of the whole fabrication process, formwork treatment and concrete pour. This work also contains all necessary aspects for meeting the quality requirements on architectural concrete.

The trend of using modern technologies in the construction industry has been growing stronger recently, particularly in the fields of additive construction or robotic bricklaying. Therefore, specifically for the purpose of robotic bricklaying, we created a digital layout plan for robotic construction works. This article presents a universal methodology for creating a bricklaying plan for various variations of wall building systems. The method is based on the conversion of drawings from the BIM (Building Information Model) environment to the BREP (Boundary Representation) model through use of the IFC (Industry Foundation Classes) format, which simultaneously divides object models into layers and connects discontinuous wall axes by means of an orthogonal arrangement and inserting details into critical structural points. Among other aspects, the developed algorithm proposes the optimal placement of the robotic system inside objects under construction, in order to minimize the distance of the robot’s movement and to reduce its electricity consumption. Digital layout plans created in this way are expected to serve as a stepping stone for robotic bricklaying.
