Despite of the advancement of monitoring devices at construction sites and the rapid progress of data management and IT, accidents in construction are still threatening not only site workers but also the public. It is difficult to cover all the dangerous areas on a construction site with expensive devices. To overcome these problems, a new monitoring method, called On Site Visualization (OSV, for short), has been developed. Unlike a conventional method of data acquisition, the use of light emitting sensors to execute monitoring by OSV enables real-time data processing and visualization on-site, so that the state of deformation, strain, inclination and etc. of concern is grasped with no delay in time and is shown visually to anyone nearby. Rational use of the new scheme based on the OSV offers a new stage whereby visually shared real-time information about the structures of concern could lead to a new paradigm of field measurement and a safer working environment. This paper describes the application example of the OSV monitoring system in the open cut excavation site of Delhi Metro in New Delhi, India. In the evaluation of the project, the role and effectiveness of OSV as a part of safety management were confirmed through a questionnaire survey given to the workers and public citizens.
