Abstract: Construction is the world’s largest and challenging industry. Productivity of every activity is important in determining the financial outcome of any construction project. Productivity tracking helps to higher cost savings. Planning manager to monitor the critical activity for successful completion of project within duration and budget this paper shows that productivity can be measured by monthly planned/targeted quantity of activity and actual quantity of work done at site. Whereas targeted quantity of activity is the input and actual quantity of work done is the output of the productivity. This analysis considers the earned value method as the monitoring system which can be used to monitor a construction project and improves productivity at site. The on-going project data is collected from the respective construction manager of the site and the planned and actual progress of site is analyzed in spread sheet. The result of this analysis shows the deviation of planned activity in site and warning sign to project manager from cost overrun and guidelines to improve productivity in site. Keywords: Construction management, Earned value analysis, Monitoring, Productivity, Progress management.
I. INTRODUCTION Productivity of critical activity will affects the overall performance of any construction site. In general terms, construction productivity can be defined as association between an input and an output. Productivity measurement at construction site enables companies to monitor their expected performance against their site performance. Construction productivity at site level can be grouped under major activities whose can affect entire construction the project. The effective system for monitoring and controlling project cost is the main reason for cost overruns and delays in the project. The Earned value analysis is basic tool to monitoring the critical activity of construction. The project becomes out of control when there is no control action taken at right place. This analysis method gives current and future state of project.
II. EARNED VALUE ANALYSIS Earned Value Analysis (EVA) is a method that required to analysis the project. Usually the amount of work actually carried out in a project and planned amount of work should to compare to track actual project status. In construction project tracking of time and cost is crucial to successfully complete the project within duration and capital cost. While tracking construction project, the productivity of critical activity monitored and control helps the planning manager to make necessary action for successful completion of project. The output of EVA is graphical representation of critical activity progress both time and cost.
III. DATA REQUIRED FOR EARNED VALUE ANALYSIS The analysis for productivity of critical activity requires the actual field data about the construction project. The following data should be collected from the planning manager. Detail planning of the project for the critical activity Monthly actual work done of the critical activity from progress report
