Research On Construction Cost Of Multiple Tower Cranes Layout Scheme

With the acceleration of urbanization process and improvement of the national economy, the development of the construction industry bring about more and more projects, and each completion of construction is a long-term, complex systems engineering, which not only make structure design is faced with the more strict requirements, also make construction suffered more severe challenges. Therefore, in order to meet the demand of the construction of the building, to adapt to The Times development, the correct selection of construction method and vertical transport equipment is essential. Thus, with the tower height, tower arm length, wide range of features such as the role of the tower crane is widely used in the engineering construction. In order to improve the economic efficiency of the project, to ensure completion on schedule, control costs, ensure the engineering quality, rapid formation of production capacity, more than one tower arranged in the building construction is becoming increasingly common. In a fiercely competitive market environment, the management of the construction unit cost of tower cranes is particularly important, which is directly related to the interests of the unit, is also very important part of the entire construction project management. Cost management of tower crane directly affect the economic benefits of the project cost and construction units, at the same time also have an indirect impact on the quality and duration of construction. Therefore, further study of the cost of tower crane, the correct selection of construction tower crane, enhance competitiveness and improve efficiency of great significance.This article mainly aims at the problem of tower crane arrangement,make the investigation of various types of tower crane, parameters, characteristics,etc. collecting a large amount of data, according to the layout principle,and the advantages and disadvantages of all kinds of layout, the use of the total cost model of tower cranes are applied for optimization of tower crane arrangement scheme provides a way.The main contents of this paper include the introduction of modern construction characteristics, leads to the importance of tower crane arrangement and practical significance of economic analysis, puts forward the main research content of this article.and based on this, I make personal summary describes on the concept and principle of tower cranes, the tower crane classification, characteristics, development status of tower cranes and domestic and foreign scholars study. Finally combination of Jinan Olympic Sports Center project as an example, the selection and arrangement of construction tower crane models will be described in detail. From the whole process of using, the constitution of the tower crane costs can be divided into fixed and variable costs.According to the model established, combined with specific project examples, compare economic and technical aspects of the different layout scheme. Finally, this paper summarized the research contents and results, and the prospects for future development to make.For the study of tower crane costs, no matter domestic or foreign, lack of comprehensive understanding and in-depth analysis,, in recent years, the cost of the tower crane in the whole construction process have a growing proportion trend, so the cost of the tower crane in the construction of project management research become very important. In this paper, the research results combined with a reasonable layout plan of Jinan Olympic Sports Center project tower crane, provide reference for similar building construction.
