Abstract

Introduction. The question of increasing the efficiency of investment and construction projects in the life cycle of facilities on the basis of modern engineering schemes becomes of particular relevance during periods of economic crisis. A formalised description of a solution to this problem is proposed on the basis of an engineering scheme for the construction Life Cycle Contract (LCC) model. The engineering scheme model for the organisation of the construction Life Cycle Contract considers the distribution of limited material, technical and labour resources, depending on the class of importance of work performed and the cost of compensation for the negative impact of random factors. Materials and methods. The methodical approach consisted of analysis and comparison of organisational structures of investment and construction activity, analysis of theory, practice and ways of improving the efficiency of modern engineering schemes for organising construction projects, methods of logical-semantic and simulation modelling and the published work of Russian and foreign scientists on the topic under study. Results. The process of implementing investment and construction projects for Life Cycle Contracts is presented in the form of a model of the engineering scheme of the organisation of construction activity. In this model, important procedures for selecting options for organisational and technological solutions, as well as the assessment and allocation of resources for the work to be performed, are set out. The coefficient of importance for each type of work is determined by a mathematical method based on the method of nested scalar convolutions, based on Bohr’s principle of complementarity and Gödel's incompleteness theorem, as well as by means of expert estimates on the normalised reversed scale. Conclusions. An evaluation of the necessity for introducing complex engineering support to investment and construction projects throughout the life cycle is given with the maximum responsibility of the organiser of a construction project to the client under conditions of the greatest concentration of managerial powers. When the results of interaction between participants in the investment and construction process are predicted in various changing conditions, the practical use of the provisions proposed in the article makes it possible to adopt adequate management decisions that increase the efficiency not only of planning but also implementing construction projects. The results of the study can be applied in the development of recommendations for the formation of a new evaluation and regulatory framework, allowing indicators of the duration and cost of construction projects to be forecast considering the negative impact of random factors.
