Abstract

Stabilizing workflow is a common goal of research in lean construction, productivity, and production control methods. This study aimed to test the hypothesis that the combination of location-based work packaging and near real-time progress reporting contributes to reducing workflow variability. Some authors agree that daily monitoring allows timely actions to correct deviations from the baseline, which can increase workflow reliability. Thus, the objective of this study is to evaluate this statement in practice. The drywall installation in a healthcare facility served as the scenario for the test study. Drywall activities were divided into multiple tasks. Tasks were associated with locations and individually monitored. Although drywall tasks with unresolved constraints with mechanical activities did experience variations, a comprehensive analysis showed that most variations of workflow were proactively reduced.

Keywords
