A Value Analysis of Lean Processes in Target Value Design and Integrated Project Delivery

Area of Science:

• Construction Management
• Lean Construction
• Integrated Project Delivery

Background:

• Lean thinking and tools are increasingly adopted in construction.
• Integrated Project Delivery (IPD) aims to improve project collaboration and outcomes.
• Understanding stakeholder perspectives on Lean-IPD is crucial for successful implementation.

Purpose of the Study:

• To identify key stakeholder-perceived advantages of using lean thinking and tools within the Integrated Project Delivery (IPD) process.
• To uncover opportunities for improvement in the application of lean tools in IPD.

Main Methods:

• A comprehensive literature review was conducted.
• A case study of a Lean-IPD project was performed.
• Data collection involved interviews, focus groups, and an online survey of stakeholders.

Main Results:

• Learning emerged as a significant, unmeasured benefit of Lean-IPD.
• Cardboard mock-ups were identified as the most effective lean strategy.
• Stakeholders perceived differing levels of influence despite the collaborative nature of IPD.
• Lean-IPD was generally rated higher than traditional design-bid-build methods.
• Key improvement areas included cost estimating accuracy, time efficiency, control/influence balance, and facilitation needs.

Conclusions:

• Lean tools and IPD are preferred over traditional methods, but stakeholder perceptions and decision-making models need refinement.
• Learning is a primary advantage of Lean-IPD.
• Addressing varied stakeholder perceptions is essential for achieving truly shared decision-making in IPD projects.
