This paper will introduce the key technology in the implementation of construction project schedule-monitoring and adjustment. We will discuss the comparison methods between actual progress and plan, including crossing chart, S curve and front line. These methods can help you better understand the actual situation of project progress, find problems in time and take measures.

Cross chart comparison method

The bar chart comparison method is a simple and intuitive method, which can show the comparison between the actual progress and the planned progress. The specific steps include making a detailed crossing plan, marking the date of each inspection, sorting out the actual progress data and describing it in proportion below the planned progress, and finally making a comparative analysis. In this way, you can find the difference between the actual progress and the planned progress in time and take corresponding measures.

s curve

S-curve is a commonly used progress monitoring method, which can directly show the changing trend of project progress. By drawing the comparison diagram between the actual progress curve and the planned progress curve, we can clearly understand the actual situation of the project progress. In addition, the S-curve can also help you predict the future trend of the project progress and take timely adjustment measures.

forward line

Frontline is a forecasting method based on project progress, which can help you predict the future trend of project progress. By calculating the position and speed of the front line, the completion time and cost of the project schedule can be predicted. In addition, the front line can also help you find problems in the progress of the project in time and take corresponding measures.
