Quality Control in Building and Construction

Abstract

When assessing construction output and buildings as such, the quality of buildings as a whole and individual construction work is a frequent and legitimate topic. In order to achieve the required quality, the quality must be predefined by the agreed characteristics, the quality marks and the values of their parameters. At the same time, we need to know the procedures, the work operations leading to their fulfilment, and the steps that the quality parameters will verify, and the criteria by which we would evaluate the quality. Construction is a product associated with the expectation of long life and durability, usually for 50 to 100 years. Thus, the relationship between quality and time is to a large extent decisive, just like the time intervals in which quality and durability will be assessed. Defining the quality requirements is the basis for the preparatory, production and evaluation procedures leading to the desired quality (quality is the degree of fulfilment of requirements by a set of internal characteristics). Qualitative requirements are determined on the basis of the user's expectations and ideas about the use of the product, the construction. The most reliable source of this information are the operational characteristics (family house, apartment house, hotel, hospital) and the operating costs considered. The information is used by the designer, contractor and building operator. They can be considered as requirements (the requirement is a need or an expectation that is set, generally assumed or mandatory) - the basis for effective design, implementation, operation and maintenance of the building. Therefore, it is necessary to pay attention to the determination of the basic requirements (their determination, including the determination of boundary conditions, limits and tolerances), and to define procedures for the fulfilment of these basic requirements in all related operations.
