Economic justification of the choice of construction equipment in the implementation of large infrastructure projects

the economic efficiency of large infrastructure projects largely depends on the rational choice of construction equipment. An incorrect machine selection strategy can lead to significant costs, schedule disruptions, and decreased productivity. The purpose of this study is to develop an approach to the sound choice of construction equipment based on an analysis of total operating costs, production performance and logistical compatibility. The paper considers typical groups of construction machinery used in the construction of highways, bridges, airports, energy facilities and main pipelines. The methodological base includes comparative, normative, computational, analytical and simulation methods. The results of the study allowed us to identify the factors determining the economically justified choice of equipment, including technical characteristics, cost of ownership, fuel efficiency, shift time utilization and payback period. The proposed recommendations can be used by design organizations, contractors and construction control authorities to optimize investment and construction solutions.
