Research On Progress Management Of Underground Business Street Project In Hunan Road,Nanjing

In the three big control,the project schedule control is extremely important content,the construction stage is the final stage of building product formation,so the strict schedule control is extremely important in the construction stage.To standardize the construction,realize the goal of the construction,it is necessary to control the construction progress,this article is about how to control construction project construction progress of the study to this problem.In order to achieve the shortest total project duration and the engineering construction project at the lowest total cost schedule objectives,based on the construction of the project during construction period and cost of each process as the research object,with basic principle and network planning optimization total time nature as the foundation,combined with the construction schedule of the basic theory of engineering project construction project time limit for a project of basic mathematical model,carries on the comparison to the key circuit and key circuit,the feasibility of the scheme design schedule optimization.And in the process of construction,in under the influence of uncertain factors,the construction schedule for dynamic management,optimization,achieve finally completed on time or even earlier and reduce cost.In this paper,the project progress is managed by the double code network diagram.In the process of the project progress plan,the six time tagging method of network graph is used to quantify the calculation period,and the existing problems are found and adjusted in time so that the calculation time is in line with the contract period.In the process of implementing the project,by collecting the actual progress data of the field and comparing the established schedule,it is found that the deviation is produced during the process of implementation,and the duration of the key line is adjusted by the six time marking method of the double code network map,so that the project schedule can be completed according to the contract goal.
