Techniques and Steps of Project Physical Progress Control through the Comparison of Site Images with Prototype Models

Abstract

Evaluation of project physical progress through statistical data prepared by project staff and project managers may cause problems in the quality of the obtained results due to human error and approximations. Therefore, making use of image and video items of as-constructed situation of projects, and their comparison with prototype models can yield detailed reports on the status of project progress. Producing site images in the form of as-built data, image analysis through image processing techniques, and comparison with prototype models is a new and rapidly growing method for preparing project progress reports.
