The hidden keys to project delivery success in the built environment

These results are being achieved across various contract types, including Design + Construction Manager, Design-Build, Progressive Design-Build, and Integrated Project Delivery (using an Integrated Form of Agreement). In contrast, the traditional Design-Bid-Build approach, where builders are selected after the complete design is finalized, significantly limits early collaboration. Nevertheless, even Design-Bid-Build can benefit from Lean practices.

A shift in client expectations

Clients leading this movement are evolving their inquiries from simply asking, “Can this be built?” to a more strategic, “How do we ensure this delivers value throughout its lifecycle?" This change in perspective significantly impacts project execution, affecting everything from pre-design strategy to closeout. By insisting on Lean-trained teams, these clients promote early alignment, data-informed decision-making, and a dedicated focus on continuous improvement. 

Lean construction prioritizes maximizing value while minimizing waste, effectively reducing both physical waste on construction sites and the prevalence of ambiguity and rework. By fostering early alignment among teams, Lean enables the identification of constraints before they escalate into roadblocks, ensuring that design decisions are closely linked to project goals. 

For example, the Last Planner System®, a widely adopted system for scheduling and production control, is not limited to jobsite coordination. High-performing owners expect to see it in use starting in the early design phases, enabling the team to track commitments, address constraints, and maintain momentum across disciplines. Similarly, Target Value Delivery (TVD) is being utilized to establish budgets that reflect real-time market data and project goals, rather than just aspirational benchmarks. 

These tools focus on more than efficiency. They build trust, create transparency, and give owners greater control over outcomes without the need to manage every detail themselves.

From process to partnership

The best-performing owners recognize that project success is directly linked to team health and collaboration. That’s why Lean-informed owners seek more than just deliverables; they invest in relationships. They take the time to select and nurture a high-performing team with regular assessments of team health and collaboration. Through Big Room environments, periodic co-location, and shared governance models, these clients foster conditions for unified teams and effective communication.

Some even go further by asking teams to conduct personality assessments, define shared “Conditions of Satisfaction,” and engage in cross-functional retrospectives. These initiatives enhance trust and minimize the risk of downstream conflict, ultimately safeguarding the schedule, budget, and project vision.

A case study in Lean leadership

Texas Children’s Hospital North Austin Campus serves as a strong example of Lean design and construction. Although the owner initially had no formal requirement for Lean practices, the design and construction team, led by Page and McCarthy, suggested a Lean-based delivery model. After reviewing industry data, hospital leadership agreed that if this approach represented the industry's best practices, “Why would we do it any other way?”

That decision proved transformative. Despite challenges from a global pandemic, supply chain disruption, and the highest inflation in forty years, the team delivered a $485 million greenfield hospital campus on time and under budget. Key practices included:

• Training the owner, architect, and contractor team in Lean vocabulary and tools
• Creating a virtual Big Room to ensure transparency and collaboration
• Deploying decision-making frameworks such as A3s, Choosing by Advantages, and Getting Decisions That Stick!
• Implementing the Last Planner System® from the design phase onward
• Utilizing Target Value Delivery to establish an achievable design-to-budget and continuous cost modeling throughout design
• Engaging trade partners (subcontractors) early and developing a prefab strategy during early design

The Lean Construction Institute named Texas Children’s Hospital North Austin Campus its 2024 Design Award winner, and the Construction Owners Association of America honored it with a Project Leadership Award. It has also won awards for planning, interior design, and construction. Perhaps more importantly, many project participants cite the experience as the most rewarding of their careers, not just because of the outcomes but also because of the culture created through Lean. Texas Children’s Hospital North Austin Campus and many other projects demonstrate a growing consensus: projects that prioritize Lean culture deliver more value. The call to action for owners is simple yet powerful: “Ask for Lean.” Include it in the selection criteria. Not because it is trendy, but because the most successful clients across the country and internationally have consistently proven that it leads to superior project outcomes.
