Methods for Controlling the Cost of Construction Projects Based on Aggregated Groups of Indicators

Abstract

In modern construction new materials, technologies, types of works are actively introduced. A major role in this is played by international cooperation in business. Planning of construction projects is carried out on the basis of a large number of reference information, standards, regulations and they in turn have to be updated actively. The article discusses the issue of cost and proposes approaches to systemic organization of work. In previous periods, isolated tariffs were subject to updating. In modern conditions it is stated that it is necessary to switch to indicators assessing the set of works, design solutions, certain volumes within the framework of the project, and taking them into account can solve local problems. This idea is not new in itself. But in the article it is proposed to approach the relevant processes through the management of an integrated database. The aggregated indicators of cost are subject to mutual reconciliation between the customer and the contractor, and this allows to allocate the isolated norms and tariffs that are relevant at a given time, which require updating, recalculation or new calculation. At the same time, the integrity of ties within the framework of an integrated database allows to make adjustments at the same time to the catalogue of resources, norms and prices, aggregated indicators of the cost of construction. The study resulted in the formation of the structural features of the relational database of information on single and aggregated indicators of the construction cost. Provided that Russian unit rates and regulations are not an international standard, their development should be carried out in the framework of Russian practice. However, for the development of international relations it is essential to form the aggregated indicators. Such indicators are based on general principles that are understandable to any investor. As a rule, parts of the construction objects or whole objects are considered. In many countries such indicators are uniform and easy to read, since the general classification of the construction projects is almost the same everywhere.
