A study of the universal sequence in construction works

Abstract

Introduction. The focus on transferring design information to experts, builders, building maintenance personnel, rather than on design in itself differs information modeling from computer-aided design (CAD) systems. The number of research papers focused on transformation of architectural and civil engineering constituents of projects into a sequence of construction and installation works is insufficient. This transformation requires methods of immediate correlation between elements and items of construction works, as well as the matching of on-site work performance schedules. The article addresses development of such a work performance sequence that will facilitate automated planning and scheduling of construction works using information modeling. Materials and methods. A classification of construction and installation works, resources and elements must encompass principal construction-related notions. However foreign classifiers, used in building information modelling (BIM), frequently fail to comprise notions, technologies and techniques widely spread in the Russian construction industry. For example, such OmniClass sections as “Products” and “Work Results” have about 7 thousand entries each, while the Russian classifier of construction resources has in excess of 120 entries, and the number of versatile regulatory standards that apply to types of works is close to 180 thousand. Having analyzed the legal framework, the author identifies domestic technical rules and regulations that contain information on design and survey, construction and assembly, commissioning, renovation, maintenance and operation of buildings, structures and process equipment. Results. The author synthesized information on technical rules and regulations and developed an overall sequence of versatile processes that comprise the life cycle of a building (a structure). The author proved that actual labour costs slightly differ from itemized standard labour inputs. Conclusions. The list of work items, broken down by priorities by the author, enables automated work scheduling based on the list of elements and building constructions. In some cases, a designer can modify the sequence by rescheduling particular work items or adding a work cluster. Further, a dictionary must be compiled to enable identification of particular construction processes on the basis of a set of parameters of a structural element.
