Assessing the complexity of old building renovation and reconstruction projects

Abstract

After prolonged use, old apartment buildings need to be renovated and rebuilt to ensure residents' health and life safety and urban architectural planning. However, these projects contain many complex factors that hinder implementation success. This study explores the factors that cause complexity in projects to renovate and rebuild old apartments. This study presents a list of 12 complexity factors by reviewing previous research. The study surveyed to measure the perceptions of project participants about the complexity of these factors. One hundred sixty-eight valid questionnaires were collected and analyzed using the Relative Importance Index (RII) method. Data analysis showed that the three most complex factors were (1) Ineffective communication between stakeholders exacerbates project complexity, (2) Low community consensus increases the complexity of the project, and (3) Challenges related to compensation and site clearance significantly increase project complexity.
