Emitting Sensors are used as the key technology. Employment of the new leads tobetter understanding of what is going on for the monitored structures, fasterdetection of abnormalities, quicker reactions to minimize further structural damages,and realization of safer working and living environment for workers and citizens.Monitoring based on OSV has been applied to more than 50 sites in Japan, as of July2015.

The primary goal of employingthe monitoring by OSV at a construction site is to improve safetyawareness both of workers and citizens so that an advanced saferworking environment with, hopefully, zero accident could be built.The questionnaires confirmed that the proposed method was wellaccepted by workers, residents, and engineers in India.

Optimizing resource allocationunder the given budget

Given conditions:1. Site to be monitored.2. Budget.

Steps to be taken:1. Divide the site into finite zones of potential risks.2 Decide what needs to be monitored in each zone considering its potential2. Decide what needs to be monitored in each zone considering its potential

risk rank.3. Decide which OSV sensors should be used.4. Decide the type of data presentation (a, da/dt, d2a/dt2).4. Decide the type of data presentation (a, da/dt, d a/dt ).5. Decide threshold values and corresponding colors of light, for example.6. Install the OSV sensors.7 Hold educational and training seminars for workers and citizens so that7. Hold educational and training seminars for workers and citizens so that

they could react correctly to visual messages sent from the OSV sensors.8. Think of clever usage of ICT with the OSV sensors.9. Make sure that the whole project is undertaken within the given budget.
