Abstract

Special conditions of implementation of construction projects of transport facilities show that cost management requires appropriate optimization of organizational and technological solutions. The computer model and method for selecting optimal management by the criterion of construction cost minimization are developed. The model shows the organizational and technological variability of the enterprise, characteristic of transport construction. The method allows to carry out variant modeling, according to which the patterns of changes in the construction cost, the ratio of direct and general production costs are compiled under the influence of the following factors: average complexity of the project totality, average relocation distance, attribution of resources, industrialization of applied solutions. The numerical experimental studies quantitatively proved that organizational and technological solutions characteristic of the enterprise as a whole affect the solutions of individual construction projects of transport facilities. In particular, it was found that with a decrease in the average complexity of the project totality, the influence of industrialization of applied solutions is reversed and begins to increase the cost of works. The lowest value of cost change (–13.6 %) was found, characterized by the most effective organizational and technological solutions: the average complexity of the project totality X 1 =2.2 thousand hours, the average relocation distance Х 2 =100 km, using only own equipment and labor resources (Х 3 =0 %), minimal industrialization of applied solutions (Х 4 =0 %). It was revealed that contracting organizations building relatively small transport facilities should use traditional methods of work. The cost efficiency of solutions, according to which enterprises constructing geographically dispersed facilities should use contracted resources with local material and technical base was also determined.

Highlights

The relevance of management of construction costs by optimizing organizational and technological solutions of transport construction is due to the main three reasons
The ever-increasing volume of transport construction indicates the importance of research in this industry
The importance of transport infrastructure construction is evidenced by the fact that in different countries the share of the transport sector varies by 8–10 % of gross domestic product

Summary

Introduction

The relevance of management of construction costs by optimizing organizational and technological solutions of transport construction is due to the main three reasons. The importance of transport infrastructure construction is evidenced by the fact that in different countries the share of the transport sector varies by 8–10 % of gross domestic product. The need to implement various transport construction projects encourages cost management by searching for the most effective organizational and technological solutions for such construction. Research on this topic should be considered relevant for the modern development of the Control processes science of management processes, in particular, methods of management of the enterprises of the construction industry and its material and technical base
