A Multidimensional Framework for Unmanned Aerial System Applications in Construction Project Management

Unmanned aerial systems (UAS) are becoming prevalent and can be equipped with cameras, sensors, or other intelligent devices that offer useful information for various nonmilitary applications, such as environmental monitoring, wildlife surveying, aerial photography, and traffic surveillance. However, a widespread application of the UAS technology has not taken place in the construction industry. One possible reason is that industrial practitioners may have not been fully informed of its functions and potentials. To let the practitioners and academics realize the true value of UAS, this study investigated a series of scenarios appropriate for UAS applications within the context of construction project management. Instead of merely demonstrating these scenarios, this paper aims to explore a multidimensional framework from four dimensions: lifecycle, managed object, potential role, and stakeholder engagement. As a guideline, this multidimensional framework is conducive to capturing the merit of UAS and functioning effectively in the total lifecycle of a project. The proposed multidimensional framework is open and nonexhaustive, inspiring an extensive adoption of UAS technology to promote current construction project management practices. Also, it offers the academics a platform for further exploring the innovative applications of various types of UAS in architectural, engineering, construction, and facility management (AEC/FM). Finally, four issues (legislation, ethics, product, and insurance) were discussed for better UAS applications in this domain.
