Research On Schedule Management Of Mechanical And Electrical Installation Of QD Metro Line 4

Mechanical and electrical installation engineering is an important part of urban rail transit.Scientific project management plays an important role in mechanical and electrical installation engineering.The mechanical and electrical installation project described in this paper is mainly constructed by the subway construction unit.Compared with the traditional mechanical and electrical installation project,it has the characteristics of cross construction,difficult coordination,more professional involvement and complex interface.Therefore,it is necessary to combine the specific characteristics of the special mechanical and electrical installation project in this paper,on the basis of the existing research,timely adjustment,to guide the project schedule management.This paper studies the schedule management of mechanical and electrical installation project of Metro Line 4,and uses scientific methods to solve the possible risks and problems in the process of schedule.The research process of this paper includes four steps: First,summarize the research status.Introduce the social background of the research,explore the frontier research methods and theories at home and abroad.By reviewing domestic and foreign literature,the research status under the current social background is summarized,and the relevant theories and research ideas are analyzed.The second is identification.Industry experts were invited to sort out the problems through field research,discussion and communication,and three aspects of problems of Metro Line 4 at the present stage were found,including the lack of initiative of project grass-roots personnel,the failure to timely implement key activities and the failure to clarify the key points of the general control plan.Third,schedule planning and optimization.Through the schedule management methods such as WBS,network diagram,key route method and Gantt chart method,the progress plan of the electromechanical installation project of Metro Line 4 is made,and the reasonable path is selected to shorten the key work period through cost comparison,so as to achieve the purpose of shortening the whole project period and meet the contract period requirements.The fourth is the study of progress control.The research framework is constructed by S-curve comparison method and earned value method for quantitative analysis.By collected in the process of the construction of relevant practical engineering information and data,and compared with early progress plan to do,find out the progress deviation,analyses the reason of deviation appears,put forward measures to rectify,so as to achieve the project can be in accordance with the plan calls for the purpose of smooth implementation,guarantee the project can be carried out in the time limit for a project plan time period.In this paper,using the network diagram method,the critical path method,S type curve comparison method and the earned value method and other research methods,through field research,and access to information,consult experts in a variety of ways,such as the subject of in-depth study,building the subway line 4 mechanical and electrical installation engineering analysis method,the progress of the model through the comparison period estimation,construction cost,constraints,resource optimization way,Makes compared to the conventional period ahead of the schedule of the project time limit for a project 16 days to complete,fully demonstrates the S type curve comparison method and the earned value method in the mechanical and electrical installation project progress management effectiveness and scientific nature,management of mechanical and electrical engineering progress effectively analyze and monitor the progress of process management,effectively avoid the construction period delay and cause project delay,It provides a scientific and reasonable project schedule model for the schedule management of mechanical and electrical engineering,and also provides an important reference for the schedule arrangement and management of other types of projects.
