Study On Management Methods Of Budgetary Estimation Adjustment Of Highway Construction

Due to large-scale and long construction period, complex technology and high human property consumption, the funds of highway construction projects objectively present dynamic changes from the project establishment, design, construction to operation. In addition, with the social economic development, in case of changes of the construction environment, promotions of design concept, inflation of prices and other reasons, Highway construction cost controlling is very difficult, resulting in a large difference between project cost of the final accounts and the estimated cost approved by the state, which affects the development of highway to some extent. How to deal with highway budgetary overrunning has become an important issue for construction unit. In this context carrying out the research of the Management methods of Budgetary Estimation Adjustment becomes significant.In order to solve the problems in the management of highway construction costs and practice, the overrunning highway construction costs are analyzed in this paper comprehensively and thoroughly, which combines with our country's actual conditions. The main research contents include:(1) The role and meaning of each period's cost is realized, and the cost control methods in the investment decisions period and the construction period, some relevant procedures to adjust the budget estimate at construction of highways are also proposed in this paper, then summing up presented problems in control of cost in highways.(2) Based on the 38 highways of our contry and 7 highways of Shanxi province, the budget-overrunning highway situations has been analysised in this paper, the main reasons of ultra-budget has been summed up in depth. In addition, the different impact brought by different factors has also been studied in this article.(3) The laws and regulations about land expropriation in recent years are introduced. The land expropriation indicators of Shanxi Province with the national are compared in this paper, which lead to the reasons of the rising cost of land acquisition demolition. And then new concepts about road construction in recent years are studied; a conclusion that different constructions concepts have different influence degree in highways over estimate has been drawn in this paper.(4) This paper deeply researches the reasons and contents of the design change in highways projects, analyzes the problems existed in the progress of design change management and draws the influence degree of the design change over cost on the highway construction. From the road technical standards, national related policy, the loan interest of construction period and the methods of fixed preparation, the effect of national macroeconomic policy adjustment on the cost of highway construction is analyzed in detail. The relevant regulations and policies about prices of construction materials are analyzed; the influence of construction materials prices on the highway construction project is quantified in this paper.(5) From the view of practical point, the proportion of road costs over almost single index evaluation and the cost ratio of almost super-comprehensive index evaluation decision-making based on interval number Hamming distance are established, and the practical examples are analyzed.(6)The reason and content of budget adjustments in railway engineering, municipal engineering, and Water Resources and Hydropower Engineering industry is researched, and the content and the proportion of budget estimate with the example of highway-related industries is studied in this paper. From these two aspects, the paper analyzes variable reasons of exceed without exception comprehensively and summarizes the content of budget adjustment. This article also bring out the notion of four time points based on characteristics of the road construction project proposed transfer; the principle and methods of budget adjustment are proposed based on the study of budget adjustment methods. With the efforts of certain studies, the advice on management methods of the budget adjustment is put forward.Through analysises, this article puts forward regularities of overrunning highway construction costs in different period and standard. The contents and methods of budget adjustment are researched and the advice on management methods of budget adjustment is proposed in this paper. It is of very important guiding significance for the budget adjustment management of the future construction project.
