Modular Integrated Construction (MiC) is an advanced type of modular construction focusing on addressing high-density high-rise buildings and is adopted as a new policy initiative in Hong Kong. Previous studies have examined the potential for using different methods and technologies to support project delivery in offsite and modular construction. However, there is a lack of systematic exploration and a paucity of examination of smart-tech solutions for MiC project delivery. This paper aims to develop a novel methodological framework of smart project delivery of MiC for achieving a better understanding of the complex process of MiC and ensuring the successful delivery of modular projects. This framework systematically structures the science, methods and technologies at four layers: sensor and data capturing, data storage and analysis, data visualization, and decision making. Drawing on the framework, key functions and technologies are explored through a systematic literature review, theoretical analysis and development, and focus group discussion with stakeholders. The framework provides a methodological basis for developing an integrative smart-tech platform for MiC project delivery. The findings of this paper are informative to practitioners and researchers for gaining a better understanding and implementation of MiC smart project delivery. The findings also contribute insights into the scientific methods and techniques of data capturing, analysis, visualization and use for dealing with complex and dynamic processes of modular building in high-density urban contexts.
