Research On Cost Management Of Multi-layer Steel Structure Engineering Based On Weighted Earned Value Method

Target management has always been the core task of project management.and the main influencing factors that affect the realization of its goals are quality.schedule and cost.Earned value method is often used in the integrated management of project quality.schedule and cost.Because of its simple theory and strong operability,it is widely used in project schedule management.However,in the construction steel structure industry,due to the unique dimensions of each steel structure building.the steel components are mostly special-shaped components,and the products are difficult to achieve mass production.Therefore,the earned value method is used in the production and construction of steel structures.It has not yet been widely popularized and used in management.This article starts with the difficulties of steel structure project management,taking the production and installation of JT multi-layer steel structure projects as a research example,combined with the tight schedule of steel structure projects,the need for multiple types of parallel construction,the characteristics of unified management,and the quality and schedule control.difficulty.Through the critical path and weighted earned value method to build a data analysis model,and then realize the integrated management of the schedule and cost of the JT project,and realize the efficient and orderly process of workshop production and on-site construction.This article describes the research status and development process of earned value method at home and abroad,and analyzes the defects of existing earned value method.applies weighted earned value method to steel structure project factory production and on-site installation.and compiles project management process.Develop project management plan,and use TEKLA steel structure 3D detailed drawing deepening software to compile WBS work task breakdown diagram,draw network plan,determine critical path,set earned value monitoring point,calculate performance index value.draw data analysis chart,analyze deviation Reasons,find out the factors causing the deviation.formulate targeted corrective measures,set a reasonable deviation early warning threshold,and use Monte Carlo simulation software to predict the project completion cost.Through the threshold warning information and the simulation data of the completion cost of the project.timely targeted deviation responses were made,the progress and cost deviation activities in the project construction process were corrected,and preventive measures were formulated to prevent the recurrence of similar deviations and ensure the project’s success.Achievement of schedule and cost targets.Expanding the scope of application of the weighted earned value method in multi-layer steel structure project management can further optimize the existing project management system of steel structure enterprises,improve the project management system,enrich project management methods,and improve the efficiency of enterprise project management.Through the case study of the JT multi-layer steel structure project,it is concluded that the application of the weighted earned value method in the multi-layer steel structure project has significantly increased efficiency in the construction management process.In the management of key tasks,the weighted performance value can better reflect the actual progress and cost performance of the project.A comparative analysis of traditional earned value and weighted earned value cost performance data can more accurately discover project cost management Loopholes in.Especially in terms of performance deviation early warning threshold selection and completion cost prediction,it has accumulated management experience and data reference for other similar projects,which can improve the project management level and comprehensive market competitiveness of steel structure enterprises.
