Integrated design and construction teams rely on rapid information exchange between the design office and the point of work on site during construction, and wearable computers can dramatically improve communication between construction personnel at the point of work on site and their off-site collaborators. In our study, using a wearable computer rather than paper documents for information exchange in building construction reduced rework by 66%. If this result may be applied to the construction industry as a whole, where rework accounts for 12% of total construction costs, the use of wearable computers could reduce total construction costs by 8%. These findings may lead to a more efficient design-construction process and to savings that may be dedicated to improving the quality of our built environment.
