Creation of a network model on the basis of a universal sequence of construction works

Abstract

Introduction. Building information modeling is the main direction of development of automated design and control systems. An important component of information modeling is the transfer of data into construction management systems. The most complicated issue is the problem of creating the correct graph topology relevant to the process sequence and construction management experience. The development of automated progress schedule compilation system based on the use of a universal sequence developed earlier is examined.Materials and methods. As a result of the analysis of the progress schedule compilation process, the topology creation algorithm is divided into several stages. At the first stage, a text description of the information model is given, which is then converted into a list of building or structure elements. The list of elements should be transformed into the work item list and then supplemented with work items not reflected in the list of elements. This is a separate complex task, which is not examined in this study, and is the direction of further research by the authors. At the next stage, the work items in the list are assigned codes that define the location of the scope of works in time and space.Results. An algorithm for converting the work item list into a coherent work schedule, the topology of which takes into account the spatial location of the work area and the sequence of interrelated processes over time, has been developed. The sequence of works is determined by a preliminarily designed universal list. The list of requirements for the information produced by BIM models is developed. Splitting the algorithm into stages allows for manual correction of the work item list and the properties of work items, if necessary.Conclusions. The developed method allows for automation of the processes of creating construction plans based on the list of building elements and universal work sequence. At any implementation stage, the work item list may be interactively changed and supplemented. In the future, it is necessary to form a set of parameters for structural elements that will allow automating the choice of technological processes.
