Jiaozhou Hai Zhuang Traction Station Transmission Project Schedule Management Research

Through the jiaozhou haizhuang traction station transmission project schedule management case study, in view of the transmission characteristics of construction projects, using the work breakdown structure (WBS) and network plan technology tools, using the Critical Path Method (CPM) to determine the critical path, and then work out a plan for the project schedule. Using the schedule control theory, set up suitable control system. In the process of project implementation, check tracking, found the progress deviation, analysis of deviation and adjustment measures, to ensure the normal implementation of the project schedule. Eventually make the project completed in accordance with the provisions of the contract date.Transmission project construction process is specification, project key line work time limit is fixed. Main body engineering mainly divided into the foundation, tower, wiring, attachment to four big engineering stage, using WBS decomposition in 6 categories,19 itemized breakdown task. Making the work breakdown structure, and further form the task table, establishing responsibility assignment matrix table. According to the transmission project construction process and similar engineering history data to determine the job successively relationship and time estimates. As part of the decomposition between overlapping relationship, using activity-on-node map the project’s overall network. Through the principle of minimum total time find the key lines. According to the time limit for a project requirements, by adjusting the working relationship time to limit for a project to optimize, work out a plan for project milestones.In the building schedule control system, the first to establish schedule control target system. Set points target according to the project implementation stage, primary objectives can be divided into civil engineering construction goals and objectives of electrical engineering. According to each stage of the main work content, form six secondary goals, establish goals at all levels closed-loop type project progress control process. Transmission process of construction projects are open environment, interference by outside factors, especially in the foundation construction stage, the ground coordinate schedule uncertainty is bigger, basic engineering has become the focus of the schedule control. In dynamic monitoring of schedule control, one is the use of chart tools include project key inspection report, project execution status report and project progress reports. Second, using in-situ monitoring and inspection methods, arrange personnel to the project department, field tracing test, and held on a regular basis the progress of the advance, establish coordination mechanism. Based on the analysis of progress deviation, using simple gantt chart comparison method, intuitive reflect the progress deviation. Project schedule to adjust some measures adopted adjustment key work and working method of combining the logical relations, to meet the demand of the total project time limit for a project. In order to ensure the smooth progress of the project schedule, according to the experience of similar projects, to make the project schedule control on the implementation of security measures, including organization, management, technology, information transmission and five aspects of quality guarantee measures.Through this research, the application of advanced management methods and tools, make the project schedule plan and schedule control measures. In practice to verify the results of theory analysis, summed up the applies to such projects of application development and innovation of technology tools. Apply to the future transmission project construction schedule management reference system, and promote its progress management standardized, scientific, to adapt to the industry characteristics of electric power construction, improving construction project progress management level.
