Building a Framework for Managing Sustainable Prefabricated Construction Systems: Using Analytical Network Process

Abstract

The management of sustainable prefabricated construction projects in Iraq suffers from outdated methods and a lack of focus on important management criteria. This research addresses this issue by developing a framework for managing sustainable prefabricated building systems and choosing the best types of systems. A review of the general literature identified 80 indicators within the 12 relevant categories. These indicators formed the basis of a closed questionnaire distributed to 90 experienced respondents. Three prefabricated building systems were identified based on the structural configuration (bearing wall, frame, and box system). The expert questionnaire for each system was conducted according to the Analytical Network Process (ANP) and using Super Decision Software (SDS). After implementation, a framework was built to manage sustainable prefabricated building systems, and the best system, which is the box system, was chosen. This framework helps improve the management of prefabricated construction projects, increase speed, quality, and pollution, and reduce the cost of housing in Iraq, which suffers from its high cost. There must be attention to prefabricated construction, as the consumption of raw materials in traditional construction is large and affects the country's resources and economy.
