A framework for identifying barriers to implementing Alternative Project Delivery Methods (APDM) in public construction of Bhutan
Main Article Content
บทคัดย่อ
Alternative Project Delivery Methods (APDM) have become increasingly popular in recent years for private and public construction projects as viable alternatives to the Design Bid and Build (DBB) method. Organizations opt for APDM to enhance innovation, streamline delivery, share risk, integrate experts, and save cost, thereby promoting economy and efficiency. However, despite the benefits of the APDM, the implementation is still low in many countries, including Bhutan due to various barriers. These barriers are complex and interrelated, with each barrier influencing and being dependent on the other. To address these issues, it is crucial to identify, prioritize, and analyze the interrelationships among these barriers. The study aims to identify and provide a structured framework for elucidating these barriers, utilizing Interpretive Structure Modeling (ISM) and Matric Multiplication Applied to Classification (MICMAC) analysis to demonstrate their hierarchy and classification. By leveraging the ISM and MICMAC analysis, this framework seeks to expedite and systematize overcoming the barriers to implementation of APDM in the public construction sector. It intends to raise awareness and inform decision-makers about the barriers that have the most significant impact, enabling them to focus their mitigation efforts effectively. This paper fills the research gap by presenting a framework to illuminate barriers in the implementation of APDM, with a numerical example illustrating the results.
