Abstract

At each stage of the life cycle, the digital model is characterized by a specific level of elaboration and respective attribute data of elements. At the stage of construction, the model is used for planning and organization of construction operations, progress control. It should contain elements providing fulfillment of the adopted organizational and technological solutions. For the formation of a building model, it is suggested to utilize technological normals of building processes. Technological normals contain basic requirements, parameters and factors for performance of particular types of construction and erection works, also special works; they also include the characteristics of required machines and mechanisms, tools, equipment and materials, labor inputs, staff qualifications and numbers, as well as the main technological solutions for execution of works. Normals can be made both for unit scopes of works and for individual structural elements, sections, assembly units. It would be useful to use normals as a catalog of standard elements for designing organizational and technological solutions in creating a building model. The structuring and standardization of catalogs (sets) of technological normals, their correlation with catalogs of building machines, structures and materials, will allow finding the most rational engineering and economic options during construction.
