Prototype Implementation of an Automated Structural Steel Tracking System

This paper discusses the prototype implementation of a system developed by researchers at the National Institute of Standards and Technology (NIST) for the transfer of real-time on-site metrology and metrology-based data for tracking steel frame construction. The purpose of the implementation is to demonstrate the feasibility of automatically transferring information from the construction site to project management databases and associated applications, specifically for the identification and tracking of structural steel subsystems. The successful integration and implementation of the on-site field data collection system with a project information management system enables a field worker to identify and track a steel member?s final position and orientation on the job site.
