Abstract

Progress monitoring is an important process during the construction phase of a project. Accurate assessment of progress allows managers to make adjustments to minimise costs when deviations from the schedule occur. Current practices of predicting the performance of a construction team require inspections that are still mainly manual, time consuming and can contain errors. Improper understanding of the current status can lead to further errors and unsuitable adjustments by the managing team, leading to more delays and increased cost. The problem is amplified when inspections take place in interior environments where the tasks are more complex. Thus, an efficient real-time progress monitoring system is needed to automate progress inspections, reducing the risks of error, facilitating proper and timely corrective actions, and preventing deviations in terms of cost and schedule. Although many researchers have proposed promising approaches for progress monitoring in outdoor scenes, these cannot shift into the complex interior environments. Research efforts for indoor environments are still premature and not fully automated. An automated progress monitoring framework will be presented, that uses an easy to use Mobile Augmented Reality System that can be used for inspections in indoor environments.
