This paper explores the relationship of Building Information Modelling (BIM) implementation and the project performance with Integrated Project Management (IPM) as a moderator in Pakistan construction industry. The study contains a knowledge gap when it comes to the interactive nature of both BIM and IPM and their impact on project performance, especially in the region of the developing nations where obstacles to BIM adoption continue to be persistent. The items of data collection were presented in a structured questionnaire which was filled by 103 professional members experienced in the field of construction work and was later analyzed by the SPSS 26 software. The reliability and validity of the constructs are supported by Cronbach Alpha coefficients (=0.83) and Kaiser-Meyer-Olkin value of the sampling adequacy (KMO = 0.877). In multiple regression analyses, BIM implementation turns out to be an important indicator of project performance (beta = 0.414; p < 0.001). The moderation outcomes verify that IPM increases this relationship (beta = 0.159, p < 0.001). As a result, the research paper serves as a piece of evidence proving that the integration of BIM and IPM could improve cost management, quality, and schedule performance and, thus, is in line with Sustainable Development Goals (SDGs) 9, 11, 12, and 13. The results add to the theory of project management and provide tangible discussion of enhancing the effectiveness of construction in a developing country.
