Developing a New Activity Pollution Index for Emissions Quantitative Assessment in Projects Construction Phase: Case Study of an Administrative Building, Egypt

Abstract

Quantitative assessment of emissions related to construction projects should be performed during the planning phase of the projects. This is significant to spot the high values of pollution during the construction phase. In this study, a model is developed to estimate pollution resulting from Buildings construction activities. The model calculates the generated pollution for each activity involved in the project as a result of dust, gases and noise emissions. A new index is developed namely Activity Pollution Index (API) which expresses the amount of total pollution for each activity during the project construction phase. Also, the developed model is able to display the resulted total pollution distribution throughout the project life that corresponding to the planned scheduling. An actual case study in an administrative building construction in Egypt is selected to demonstrate the practical use of the proposed model. The results show that the peak and minimum values of total pollution were occurred during the excavation activity and the formwork erections and steel fixing of the second segment of the building with values of API equal to 69 and 2, respectively.
