Visual Representation of Construction Progress Monitoring Metrics on Time-Lapsed Photographs
Construction project managers need to be able to effectively communicate progress information with the capability to represent as-built and as-planned progress discrepancies. These progress monitoring components are important for successful projects management, so corrective decisions can be made in a timely manner. The current formats of monitoring reports (e.g., textural progress reports, s-curves, and photographs) can require extensive data extraction, therefore slowing down the communication process and possibly providing inaccurate data. These current methods distract managers from important task decision making, which is their primary role as a project manager. In order to facilitate progress monitoring, this paper proposes a visualization of performance metrics that aims to represent progress deviation through superimposition of 4D as-planned models. While contextual information in the photographs is preserved, the as-built photograph is augmented with a 4D as-planned model, in which progress monitoring metrics are visualized. The augmented photographs provide a consistent platform for representing as-planned, as-built and progress discrepancies, facilitating communication and reporting processes. In addition, an automated systematic technique enables the project manager to collect and evaluate progress data and communicate it in a holistic manner.
