Information modeling of the construction and demolition waste system

Abstract

Throughout the world, the intensive development of production is accompanied by a steady increase in waste generation. Ecological problems, problems of utilization and recycling of waste come to the fore. The effective functioning of the construction complex is largely determined by the effective organization of the construction and demolition waste (CDW) circulation. Considering the scale of construction, forecasting the volume of waste formation in order to effectively organize the system of economic turnover of CDW is a very relevant scientific and practical problem. Management of CDW flows in Smart cities should be based on information models containing the necessary data on the types, forms and volumes of waste. The paper presents such an information model and a mathematical method of predicting the formation of the CDW. Information modeling of the composition and volume of CDW formation allows on the basis of the developed mathematical apparatus to provide an analysis of construction development trends. It allows to carry out construction production operational and strategic planning and management in terms of the CDW formation, processing and disposal. Analysis of the construction, reconstruction and demolition CDW volume dynamics information model is the basis for further design of treatment plants future scheme.

Assessing construction costs for agricultural facilities: organizational and technological strategies

“…Thus, the use of the concept of managing the cost of an investment and construction project in the practice of management systems increases the level of analytical work in enterprises of any type, contributing to the growth in the number of standard developments in management analysis and expanding the possibility of comparing and generalizing its results [5].…”

“…The subjective production of value in this concept suffers precisely in the aspect of nonfor material costs, although the subject undoubtedly bears their burden, i.e. transforms its monetary resources into inventories and work in progress when creating the value of a construction project [5].…”

The importance of automating the “Construction” phase of the construction project life cycle

“…Since the end of the last decade, when works defining the stages of the building lifecycle were published [3,4], and up to now, a considerable part of such works, both domestic and foreign, has been devoted to the issues of information modeling at the pre-project and project stages of CPLC [5][6][7][8][9][10][11].The prerequisite for this was the development of industry-specific digital management decision-making support systems to meet today's demands for efficient planning, design, operation and ongoing management of construction objects. In the Russian Federation, such a system is supposed to base on the wide application of information modeling technology at all stages of the life cycle of capital construction and infrastructure objects [12].…”
