Abstract
This study investigates the influence of three most influential construction risks, namely, design and documentation risks, site operations risks, and contract and management risks on cost escalation of highway projects with the moderation effect of social sustainability requirements. The data were collected from 210 professionals working in various highway projects in Pakistan through questionnaire survey. The data were analyzed using Barron and Kenny approach. The results obtained from the research validate that the selected construction risks are significant predictors of cost escalation in highway projects and should be mitigated appropriately. The results of analysis also imply that social sustainability requirements significantly enhance the positive relation of construction risks with the cost escalation. The project managers should cater to the social sustainability requirements during the early stages of the project to avoid subsequent variations that result in delaying of project and ultimately the cost escalations. This can be an essential contribution to the existing literature as many projects are prone to cost escalations due to social sustainability issues.
