Video-based progress measurement for assessing jobsite concrete construction productivity

Productivity assessment is an important task both before and during construction, while progress measurement is the key component in productivity assessment. In addition, timely and accurate measurement of work progress on construction sites provides valuable information for project time and cost control. The use of computer vision may provide an opportunity for assisting this particular project management task. Using concrete construction as an example, this paper presents a study in which construction progress was measured by using image processing method. The research results indicate that the proposed method can effectively detect and extract the completed concrete region in the image frames. This potentially facilitates automatic work progress measurement on construction jobsite for productivity assessment purpose.
