Abstract
Information model of the construction process on the example of bricklaying
Incoming article date: 20.05.2021The issues of construction and practical application of 4D BIM models relate to the current issues of the development of organizational and technological design of construction at the international level. The purpose of the work is to describe the information model of the construction process on the example of brickwork. To achieve this goal, the following tasks are solved: the structure of the source infor-mation necessary to describe the changes in the construction process in space and time is developed; analytical dependencies describing the changes in the construc-tion process in space at each moment of time are obtained; the procedure for evaluating the effectiveness of organizational and technological decisions made by the designer and contractor when performing bricklaying is given. The methods of algebra and analytical geometry were used in the research. As the initial informa-tion, the data provided in the national classifier of construction resources and the register of estimated reserves are used. Analytical models are formed as a result of applying a systematic approach and methods of mathematical logic. Conclusions: 1. To build an information model of a separate construction process, it is advisable to use the existing base of estimated standards in construction. 2. It is recom-mended to apply the well-known equations describing the change in duration from the volume of labor and material and technical resources. 3. Evaluation of effi-ciency using the information model involves a comparison of at least 13 variants of the organization of work on the device of the brick masonry.
