The investigation objective of this study is to collect data for environmental impact around demolition sites keeping in view the direct, especially the workers and indirect, the people living in the three boundary residences around the civil structure being demolished. At all the three location of instruments (points) around the sites the air quality data was recorded, monitored and collected without break for concentrations of Particulate Matter i.e. PM10, PM2.5, gases Sulphur Dioxide (SO2), Nitrogen Dioxide (NO2) and Carbon Monoxide (CO) along with Noise Levels. Three locations at the main entrance and two flanks of the demolition sites were equipped. The three stages were before, during and after demolition to accurately assess the parameters being evaluated. The data has been recorded for 12 days i.e. 3 days before, 5 days during and 4 days after demolition for a total of Ninety Six (96) hours. The quantification is done at the laboratory. The result as was expected, the PM10 emissions is beyond permissible limits during peak demolition activities. Hence, it can be concluded that care must be taken regarding the health of the people working on the site as well as the people in the residences around the site.
