This study aims to examine the role of Relational Stakeholder Management (RSM) on the success of sustainable construction projects in urban areas of Pakistan. The study also examines the mediating role of trust (competence trust, integrity trust, and intuitive trust) and the moderating role of project managers’ leadership skills. Data were collected from 303 professionals working on sustainable construction projects in Pakistan and analyzed using Structural Equation Modeling (SEM). The results show that RSM has a positive and significant direct impact on the success of sustainable construction projects, while competence trust and integrity trust mediate this relationship. However, Intuitive Trust did not mediate the relationship between RSM and project success. Furthermore, the project manager’s leadership competencies strengthen relationships with relational stakeholders and foster trust, thereby improving overall project success. This research highlights that, in addition to technical factors, human and relational aspects are crucial to the success of energy-efficient and low-carbon construction projects in urban areas of Pakistan. The study provides integrated empirical evidence on the interplay between stakeholder relationships, trust, and leadership, specifically in the context of sustainable construction projects in urban areas of Pakistan. The findings of the study provide practical insights to improve RSM, develop trust, and strengthen leadership competencies to enhance success in sustainable construction projects.

Purpose: The main objective of this study is to identify moderating effect of pandemic covid-19 and project evaluation management between construction project performance indicators and projects success. Construction Project performance indicators were found to have a significant influence on Project Success along with the moderating role of Pandemic Covid-19 and Project Evaluation Management Design/Methodology/Approach: A quantitative research strategy is used to collect primary data from the 250 project managers working in construction firms in Pakistan. A questionnaire survey is used to collect data and the collected data is analyzed by performing tests of reliability, validity, correlation, and multiple regression analysis in SPSS software, and the moderation effect is studied by using Hayes Process Macro. Findings: The study concluded that communication factors, Supply chain factors, and Human Resource factors have a significant effect on the success of the project. When these three construction Project Performance Indicators are moderated with Pandemic Covid-19 and Project Evaluation Management show significant results, The results conclude that both moderators significantly moderate the effect of Human Resource Factors, Supply Chain Factors, and Communication Factors on Project Success. Implications/Originality/Value: The findings of this study will be helpful for the practitioners to minimize the effect of Pandemic covid-19 by adopting proper project management techniques.
