Establishment And Application On The Management Method And Information System Of Highway Engineering Cost

With the great development of information technology,the traditional management mode of engineering cost can not satisfy the need of the high-speed development.As an important part of informatization in construction field,engineering cost informatization will play an important role in construction cost management activities.It is an important support of engineering cost management activities,and will lead the future development direction of engineering cost management activities.With the rapid increase in the cost of engineering information and changes,the engineering cost information is also facing challenges and innovation.The accurate,timely collection and release of various materials market price information play a positive role in determination of cost in every stage of highway engineering construction,the interests of all parties participating in the construction of security,improvement of traffic information service level.It is the trend of traffic construction industry to set up a perfect material price information system for traffic construction projects and supply the valuation basis of traffic construction projects.Under this circumstance,the management and prediction of highway engineering cost,and the construction of material information are particularly important.The cost management of highway industry in China is difficult and the accuracy of cost prediction is not high.In this background,this paper takes "highway engineering cost,especially highway cost" as the object of study,By means of theoretical research,thorough investigation,case analysis and system development,the highway project cost management,cost prediction and the empirical design of multi dimensional information system for cost were investigated.It aims to to reveal the essence causes of the problem of highway construction cost,and to establish a fast estimate and prediction model for highway construction cost.Finally,the multi dimension information system design of highway construction cost can be realized.The main research contents of this thesis include the following aspects:(1)Highway engineering cost management method analysis.In this part,the basic principle of each stage of highway engineering cost management,the highway engineering cost management system and management mode,the key problem of cost management of highway construction,highway project cost pricing problems were analyzed and discussed.Moreover,the basic theory of highway construction cost management was also analyzed.Through such analysis methods,the key points and key problems easily ignored in highway engineering cost management were clarified,thus laying the foundation for further research(2)National survey and analysis of highway project cost management.The research work of highway engineering cost management has been carried out nationwide.On the basis of scientific arrangement and analysis of research results and data,highway project cost management can be carried out in-depth analysis of the development and problems,and then put forward targeted countermeasures.It can provide scientific and reasonable analysis basis for highway project cost management in the future,and also provide the basic support and decision-making basis for improving the investment benefit of highway construction project.(3)Influencing factors of highway construction cost and cause analysis of cost change.Taking Hurongxi expressway as the background of Engineering Research,the relevant departments have collected the basic data of construction costs at different stages of construction because of the great change in the quantity of the highway project.At the same time,the data of the construction cost change caused by the highway located in the mountain area and the quota basic data were collected.Through these basic cost analysis data,the current situation of the highway project cost can be analyzed,and the experience and difficulties in the cost management work can be summerized.Through the study of its internal reasons and the main factors affecting the cost of the highway,this paper analyzes and proposed the corresponding solutions.(4)Rapid estimation of highway engineering cost and forecasting model of cost.Based on the analysis of the current situation of highway engineering and the construction of the project volume and cost in the process of construction of Hurongxi expressway,the overall index of expressway engineering quantity and cost is constructed.On the basis of obtaining reasonable indicators of bridges,tunnels and subgrade,taking into account the needs of different stages of the project(Pre-feasibility,feasibility,etc.)and different levels of cost management personnel,the method of statistical analysis and neural network was used to establish the rapid estimation method and cost forecasting model of highway engineering cost: intelligent forecasting model and index system forecasting model,and the error analysis and checking of the two models were provided,which could provide the correct estimate of the expressway engineering quantity and the project cost in the preliminary design stage.(5)Analysis of highway engineering cost information management.The basic problems such as the attributes,characteristics,functions,acquisition and processing of road construction cost information were analyzed.Based on this,the basic principles of highway project cost management were explored,which provided the basis and the way for highway engineering cost management theory research and cost management work practice.(6)Development of Hubei province highway engineering material price management information system.Taking the "Hubei Province Highway Engineering Material Price Management Information System" as an example,the multi-dimensional information system of highway engineering cost was designed and realized.Unified Hubei highway engineering materials coding system was developed.The use of Internet technology and database technology,the establishment of an efficient and efficient material price information collection system were carried out.Through the geographic information system technology,convenient and practical material price electronic information map release system were established.On this basis,the final establishment of highway engineering materials in Hubei Province price information system platform achieved the Hubei Province road material price information sharing.The main achievements and novelty of this paper are:(1)The research work of highway project cost management is carried out nationwide,and the results and data of scientific research are analyzed and analyzed scientifically.This paper analyzes the present situation of the cost of the expressway project,the current situation of the expressway project cost,the current situation of the expressway project cost,summarizes the experience and difficulties in the construction of the expressway in the construction process,clarifies the main factors that affect the cost of the expressway,and analyzes the causes of the cost changes and puts

establishment of an efficient and efficient material price information collection system;through the geographic information system technology,the establishment of a convenient and practical material price electronic information map release system.And finally established the Hubei highway engineering material price information system platform,to achieve the province of road material price information sharing.
