Research On Schedule Plan And Schedule Control Of HH Intercity Railway Mechanical And Electrical Installation Project

On the basis of the "four vertical and four horizontal" high-speed railway network,the country plans to form the "eight vertical and eight horizontal" main channel skeleton,and cooperate with the intercity railway as a regional connection to promote the large-scale construction of the national railway.At the same time,there are 56 in the country.The city is carrying out rail transit construction,with a total of 253 lines under construction and a length of 6,218 kilometers.With the continuous growth of investment scale in the railway and urban rail construction market,and the constant regulation of the market environment,the requirements for construction safety and engineering quality have been continuously improved,and the requirements for enterprise construction capacity and project management level have been raised to a new height.And project schedule planning and control is one of the important factors in project management.Therefore,how to effectively weave the project schedule,optimize according to the characteristics of the project,and effectively monitor and control the schedule is an important topic for the construction company to study the schedule and control of the project.The HH Intercity Railway is an important strategic significance for the HN City to meet the needs of the people for convenient travel and to adapt to the development of new urbanization.It also has important strategic significance for the economic development of the city,the linkage with the provincial capitals,and the promotion of regional integration.As a contractor of the electromechanical installation of the project,China Railway has analyzed the project's general situation and characteristics,and analyzed the problems existing in the implementation of the project schedule,such as the delay of the project,the high requirements of the owner's investment task,the unpredictable risk factors,and the cross construction.Many,project construction is complex.Through research and analysis of project issues,it is proposed to formulate solutions from three aspects:project schedule,project schedule control and safeguard measures.In the project schedule,WBS decomposition of the project construction content,and parameter setting of the work package,forming a work package dictionary for review of schedule planning and progress control implementation,improve work efficiency and accuracy.According to the requirements of the project schedule,choose the appropriate schedule planning method from the three methods of critical path method,lap network,and compression critical line work duration.Finally,the project schedule is formed by setting the buffer and human resource balance optimization,and the risk resistance and feasibility of the schedule are improved.In the project schedule control,according to the problems existing in the project,set the monitoring elements,formulate the progress control process,determine the actual progress monitoring and data recording content,and study the actual progress of the front-line comparison method,the index method,and the list comparison method.The progress deviation analysis analyzes the progress deviation analysis method of the research by presetting a set of project progress data,and simulates the implementation of the project schedule control,and obtains the expected effect of the project schedule control.Finally,through the formulation of organizational guarantees,management guarantees and resource guarantee measures,the smooth implementation of project schedule and control is ensured to complete the research.Through the research on the schedule and control of the HH intercity railway project,the experience of project schedule preparation method selection,work package dictionary setting,resource balance optimization,schedule deviation analysis method selection,schedule monitoring factor setting,schedule adjustment,etc.It plays a certain reference role for the schedule planning and control practice of similar projects,and looks forward to the direction and use prospects for further research in the project schedule management practice.
