Which project delivery approach may be better for higher-quality buildings?

• A. Design-Bid-Build
• B. Integrated Project Delivery
• C. Design-Build
• D. Construction Manager as Adviser

Answer: (B)

Integrated Project Delivery centers on collaboration among owner, design professionals, and constructors from the very start, with shared goals, joint decision-making, and aligned incentives. This setup keeps design and construction teams working together throughout, which helps optimize constructability, resolve conflicts early, and reduce rework. With early input from builders and operators, decisions about materials, details, and sequencing can be made with real-world implications in mind, often supported by BIM and lean methods. The result is higher quality outcomes because issues are identified and addressed before they become costly defects, leading to better coordination across disciplines, improved build quality, and better lifecycle performance.

In contrast, more siloed approaches tend to introduce fragmentation and late-stage changes that can compromise quality. While Design-Build merges design and construction responsibilities, it may not achieve the same level of multi-party collaboration and shared accountability for quality as IPD. Construction Manager as Adviser involves early involvement but typically without the same integrated, risk-and-reward sharing that drives the highest-quality outcomes.
