The relevance of the article is conditioned on tourist infrastructure problems and underdevelopment when creating and developing territorial clusters, for which there is not enough research materials in the context of tourism cluster facilities construction, despite the fact that the issues of lean construction (LC) are widely covered. Based on the relevance, the main hypothesis of the study was determined. It consists of the fact that the use of lean construction can increase the efficiency of construction megaprojects in the field of tourism clusters. The objective of this study is to develop a mechanism for the development of tourism clusters based on the lean construction concept that will be aimed at increasing the efficiency of construction projects taking into account the accumulated world experience. Within the framework of the tasks set, the analysis of the lean construction methodological base was carried out, methodological recommendations aimed at increasing the efficiency of construction megaprojects of tourism clusters based on the lean construction concept were developed, a model for the implementation of lean construction in infrastructure projects of tourism clusters, as well as a checklist of the analysis technology were elaborated. The proposed methodological approach to the implementation of tourism cluster megaprojects based on the lean construction concept is the basis for organizing and planning development activities at the tactical and operational levels. To assess the effectiveness of lean construction tool introduction to implement infrastructure projects of tourism clusters, a comparative analysis was carried out and the construction time and lifecycle cost of a typical guest house were calculated without taking into account the lean construction methodology and after its introduction. The results obtained, namely, the duration of the project and costs at life cycle stages made it possible to conclude that the proposed methodological approach is effective.
