Abstract

This master's thesis presents the research results of new construction organization – lean construction. The main its goal is the detection of all possible losses during execution of works, analysis of their appearance causes and subsequent decreasing of their influence or elimination. The implementation of lean construction systems leads to lower the costs, improve the quality of works, productivity on construction site, reducing the time of construction. This concept applies not only for the construction of residential, but also public and industrial buildings and structures. Unfortunately in most cases the introduction of concept is performed only on separate sites and immediately prior to the beginning of works production, often only within individual projects, but not the whole production system. Therefore it is necessary to provide a system that will allow identifying losses at the pre-investment phase, that paving actions to mitigate losses or to eliminate them even before the beginning of the project, to develop organizational measures for the improvement of production indicators and to identify all deficiencies in work organization. For this purpose the assessment of losses has been proposed arising from the point of risk management view and loss control system has been developed at building site.
The paper discusses currently existing methods of risk assessment in construction projects for this purpose implementation. The improved method of assessment and management the losses on the construction site was developed. The method provides to assemble the expert commission with specialists in the field of industrial and civil construction, compiles the list of qualities that should be possessed by each expert performs a survey on the losses assessment, levels of competence of each expert. The development of universal criteria for evaluation of the project from the losses point of view arising during its implementation has been proposed. The method for the formation and ranking of the losses register has been developed within the allocation in them the most significant and development of elimination measures or the impact reduction on the production process. Recommendations of monitoring process organization, control of made changes and documentation has been provided.
The proposed method of losses management is realized on the example of the in-situ reinforced concrete works. The analysis of processes, identification of losses, their evaluation and ranking has been made, the integral indicator of efficiency has been determined with the verification of results and the measures to prevent and reduce the impact of loss on the works have been proposed. The obtained results show the possibility of reducing the cost of works execution and construction time up to 20-25%.
