Research On Cost Management Of Construction Projects Integrating Lean Construction And Blockchain

The construction industry is an important pillar industry in my country.In recent years,as the demand for the transformation of the construction industry to high-quality development has become more and more urgent,higher requirements have been put forward for the timely and high-quality delivery of construction projects.How to improve the cost management ability for construction enterprises to survive and develop in a more limited profit space is a severe challenge they face.The traditional construction project cost management system is established on the basis of task management,taking construction tasks as the main cost budgeting and accounting objects,ignoring a large number of activities in the construction process that are not helpful to the improvement of project quality,and cannot fundamentally target the production costs.Cost activities are effectively managed,resulting in serious cost waste and high costs.In the "14th Five-Year" development plan of the construction industry in Jiangsu Province,"lean construction" and "blockchain" are mentioned as powerful tools to promote the upgrading of construction methods.This paper integrates the two in the cost management of construction projects,optimizes the construction process,strengthens the communication and cooperation between the subjects of cost management,reduces the cost from the root,and improves the cost management system.The research content of this paper mainly includes the following parts:First,the problems existing in the cost management of traditional construction projects are investigated.Based on the "Transformation-Flow-Value"(TFV)theory of lean construction,this paper designs a questionnaire,investigates wasteful activities in construction projects,and clarifies the cost management problems that need to be solved;secondly,it discusses The fit of lean construction and blockchain with construction project cost management clarifies the advantages of lean construction in identifying and eliminating process and value waste,while blockchain is conducive to the management of construction information and the traceability of cost information;then,the construction of lean construction Building a construction project cost management framework integrated with blockchain.The use of lean target costing,the last planner system and just-in-time procurement to solve problems such as inaccurate cost estimates and wasteful activities,while blockchain technology creates a collaborative,transparent sharing of project information,and can ensure information integrity.With a safe computer environment,lean construction can better serve cost management,intervene in construction projects under advanced management methods and technical methods,and ultimately achieve the purpose of reducing costs.Finally,carry out a project case simulation.The cost management process was simulated using Lean Construction in a civil construction project,the cost of eliminating wasteful activities was calculated,and the uploading of cost management related information on the blockchain platform by Contractor B was shown.Validated the validity of this framework.Based on the problems of wasteful activities and poor cost management in construction projects,the research of this paper proposes a solution to the application of lean construction and blockchain integration to construction project cost management.The application of lean construction and blockchain in construction project cost management It has theoretical and practical significance.
