Modular construction has emerged to help address the challenges posed to the construction industry by stagnant productivity rates and a shortage of skilled labor as it allows for greater automation and for work to be completed in a controlled fabrication shop environment as opposed to on a construction site. This requires tighter tolerance controls than traditional stick-built construction because the components must fit together easily with minimal on-site intervention.
The results of the completed study show that the use of an augmented reality software can increase productivity and minimize the impact of rework for both expert (pipe fitter) and drawing-literate (engineer) users. The revised workflow created through the usage of such a software essentially eliminates traditional rework. It was found that all users can benefit from the use of such a tool but that users who have lower spatial cognitive skills benefit the most.
