| In recent years,with the rapid development of China’s economic strength and the continuous improvement of people’s living standards,the number of cars has gradually increased,and the traffic problems in developed cities have become increasingly prominent.The subway has become the leader of rapid rail transit in large cities with its advantages of speed,land saving,environmental protection and high efficiency.In the process of subway construction,the construction process is complicated,the cost is high,the construction period is long,and there are many uncertain factors.The traditional project management model has been difficult to meet the management of large-scale livelihood projects such as the subway,and the BIM technology uses the three-dimensional model as the carrier,which is different from different angles.The stage provides new ideas for project management.This article takes the BIM technology-based research on the construction schedule management of a Hangzhou subway station as the topic.First,it explains the research background and necessity of the subway schedule,the status quo of BIM schedule research at home and abroad,research content,research methods and technical routes.Secondly,it analyzes the conceptual principles and existing problems of traditional schedule management methods,and further explores the application value and advantages of BIM technology in project schedule management on this basis.Then it analyzes the relevant situation of the project instance that needs schedule management,creates a 3D model of this project,and decomposes the work structure of this project to formulate a related schedule plan,and conducts an introduction to the construction of the schedule-4D model.Then comprehensively use BIM technology to control the progress of the project’s three-dimensional model:optimize construction site layout,simulate dynamic construction,count engineering quantities,collision inspection,link real-time information,create progress-4D model,and apply BIM software to real-time progress Track,and analyze and optimize the progress in conjunction with the earned value method.Finally,it compares and analyzes the differences between traditional schedule management and BIM technology schedule management in actual projects,and summarizes the benefits and improvement measures that BIM technology brings to project schedule management,and provides efficient and convenient new ideas for managers to control on-site schedules.,new method.This article provides a new idea for the application of BIM technology in subway schedule management,sorts out advanced management experience,summarizes the latest management results,and proves that the results are conducive to improving the level of refined management and control of the project,and provide great opportunities for related similar projects.Reference value case. |
