The paper will explore formwork used in the construction of concrete wall panelling. Formwork, as auxiliary construction, has a wide spectrum of use and as such deserves special attention in the field of civil engineering. Furthermore, assembly and disassembly of formwork plays a huge part in the construction time and the cost of reinforced concrete constructions. Consequently, knowledge of formwork and choosing optimal technology are tremendously important for saving money and easing the construction process. Functional requirements and the criteria of quality that every formwork system must fulfil are defined in this paper. Furthermore, the paper explores which factors dictate choice of work process and the type of formwork. The paper also delves into the materials used in the making of formwork by comparing wooden, steel, aluminium other types of formwork. The following basic elements of formwork assembly are described and shown with images: formwork panels, subcostructions, load-bearing constructions, binding agents and regulation devices. Lastly, the paper explains the classification of contemporary formwork systems according to the respective construction technologies in detail and every system is studied further through selected examples.
