Relationship Between Project Delivery Systems and Critical Success Factors for Construction Projects
Introduction to Project Delivery Systems in Construction
Project delivery systems (PDSs) are the frameworks through which construction projects are executed. Common PDSs include design-build (DB), design-bid-build (DBB), construction management at risk (CM-at risk), and integrated project delivery (IPD). Each system has unique characteristics that influence the project's success, and selecting the appropriate PDS is crucial for achieving desired outcomes.
Critical Success Factors (CSFs) in Construction Projects
Critical success factors (CSFs) are the essential elements that significantly impact the success of construction projects. These factors vary depending on the PDS employed and the specific context of the project. Research has identified numerous CSFs across different PDSs, highlighting the importance of understanding these factors to enhance project performance.
Collaborative Delivery Models and Success Factors
Collaborative delivery models, such as alliances and partnering, emphasize mutual trust, equality, and a commitment to a win-win philosophy. These models have been shown to improve project organization, contractual relationships, and operational systems. Key CSFs for collaborative construction projects include mutual trust, commitment, and effective communication among stakeholders.
Integrated Project Delivery (IPD) Systems
IPD systems integrate all project participants early in the process, fostering collaboration and shared risk/reward. Research in the Korean construction industry identified seven CSFs for implementing IPD, including stakeholder engagement, top management support, and effective communication. Additionally, a study of 16 IPD projects found that factors such as schedule performance, cost performance, and defect management are critical for success.
Traditional Project Delivery Systems
Traditional PDSs, such as DBB, often focus on clear goal setting, project management competency, and top management support. These factors are crucial for managing the complexities and uncertainties inherent in construction projects. A comprehensive analysis of various PDSs highlighted the importance of owner-related issues, contractor issues, and regulatory impacts in selecting the appropriate delivery method.
External Environmental Factors
The external environment significantly influences the selection and success of PDSs. Factors such as market competitiveness, technology accessibility, material availability, and regulatory impact are critical considerations. These external factors must be carefully evaluated to ensure the chosen PDS aligns with the project's context and external conditions.
Sustainable Construction and Modular Integrated Construction (MiC)
Sustainable construction projects require a focus on environmental, social, and economic factors. Key CSFs for sustainable construction include project financial issues, managerial aspects, and regulatory approvals. Similarly, modular integrated construction (MiC) projects emphasize effective supply chain management, accurate design, and early design freeze as critical success factors.
Conclusion
The relationship between project delivery systems and critical success factors is complex and multifaceted. Understanding the unique CSFs associated with different PDSs is essential for improving project performance and achieving successful outcomes. By considering factors such as stakeholder engagement, top management support, and external environmental conditions, construction professionals can better select and manage PDSs to enhance project success.
