An integrated social, environmental, economic, and statistical analysis is conducted of Karachi’s construction sector in an analyzed case study and survey. The methodology involves the identification and ranking of adverse impacts and quantification of social costs based on well-known analytical models. The results have implications for the Environmental Impact Assessment (EIA) process improvement within Pakistan’s construction sector. Knowledge of social ranking helps decrease adverse social and cultural effects and it can result in improvement of the EIA framework. It has been found that the vehicle operation cost covers 67% of the total social costs and the total social costs are 68% of the total cost of project. This amount is currently not considered by the professionals in the initial stages of the project and can lead to saving for society, if considered. This type of analysis can prove to be a new dimension of research for academics as well as for the professionals related to construction industry.
