Management of construction resources, such as workforce, equipment, and material, is critical to project success. Completion of work tasks on schedule, safely and within the proposed budget requires a coordinated planning effort that allocates adequate availability of project resources. Because this task alone can become a challenging and time-consuming effort for many field personnel, several existing technologies are reviewed for their benefits and limitations in keeping oversight of resource location and status at job sites. To ensure the optimal solution using the right resources, such knowledge becomes even more meaningful when optimizing construction logistics and safety at the same time. This paper introduces an emerging sensing technology called ultrawideband (UWB) that is capable of determining three-dimensional resource location information in object-cluttered construction environments in real time (up to 60 Hz). The use of UWB is explained in a variety of construction applications including simplifying on-site management, improving resource productivity and usage, reducing schedule and cost, and increasing work zone safety. UWB technology and its advantages and limitations are compared with the state of the art in positioning technologies. Results of preliminary UWB experiments in the laboratory and construction environment are presented using developed data processing algorithms and a method to determine the accuracy of UWB position measurements. The paper discusses the feasibility of using ultrawideband as a data collection and decision support tool for robotic (automated) infrastructure construction applications in the areas of real-time three-dimensional material flow and workforce location tracking, optimized machine positioning and automated navigation, and proactive work zone safety.
