Schedule Planning And Control For River Crossing Reconnaissance Project At Changyong Section Of X Natural Gas Pipeline Engineering

With the increasingly fierce competition in reconnaissance design market,the demand of construction unit on reconnaissance project schedule is more and more high.As the initial stage of construction project,the reconnaissance project has great influence on cost,quality,and social effect and so on at later period of the whole project.If effective planning and control on the schedule of the reconnaissance work at earlier period cannot be performed,it will inevitably delay a series of subsequent design,construction,service and operation and other work,and even lead to large economic loss.Therefore,the application of project schedule planning and control theory to the reconnaissance stage of construction project will have very important significance.The research object in this paper is the river crossing reconnaissance project at Changyong section of X natural gas pipeline engineering.The scheduled completion is the top-priority target of the project,therefore,the planning and control of the project is a very important work.The relevant theory and tool of project schedule management are firstly introduced in this paper.And then starting from the practical features of river crossing reconnaissance project at Changyong section,the management theory and method of project schedule planning and control are applied in the practical engineering reconnaissance project.Through the decomposition of work structure of reconnaissance project,the network diagram for work is drawn,the schedule planning chart for project drawn later of critical path is analyzed,and main countermeasures for guaranteeing the schedule planning and control of reconnaissance project are put forward.Meanwhile,during the construction of the project,the practical schedule data is collected,the deviation from design schedule is analyzed,the reason for schedule deviation is searched,and control measures are put forward.At last,the optimization on project schedule management is performed,so as to guarantee the scheduled completion of river crossing reconnaissance project at Changyong section,and lay a good foundation for subsequent design,construction and operation.The application of management theory and method of project schedule planning and control to the engineering reconnaissance project can help the schedule planning management work more scientific and more systematic,and even improve the project schedule management and control level.It has important significance for reconnaissance enterprise to adapt to the new form of market better and improve its market competitiveness.Meanwhile,the practice of reconnaissance project can also provide valuable practical experience for project management theory.
