The on-site management of construction projects involves a great amount of verbal communication
and paper based systems. This isolated sequential process creates many barriers for effective
collaboration and has often resulted in costly rework on the site. Delivering task instructions
to construction workers on site is one such example where a worker is instructed verbally for
execution of a certain construction activity. The ineffective communication between the
supervisor and the worker often results in various inefficiencies on site. Especially when a
low-skilled worker is instructed in this very manner chances of comprehending instructions
reduce to a much larger extent due to the inability of many workers to visualize the task
understand a construction operation and the language spoken on site. This research study has
developed a digital construction task instruction model capable of covering the gap lying under
the traditional methodology of instructing low-skilled construction workers on site. The
proposed task instructional model with the application of BIM based knowledge management
encompasses animated video tutorials of construction tasks in order to formulate a digital
instruction and learning environment.
