Design build Project Delivery: Lessons from Industry Leaders

As construction projects become increasingly complex, owners are looking for project delivery methods that improve collaboration, reduce uncertainty, and create greater confidence in budget and schedule. Insights shared during the Design-Build Institute of America (DBIA) Iowa Chapter's Lessons from Leaders breakfast reinforce that successful design-build projects are built through trust, early collaboration, and informed decision-making.  

Every successful construction project begins long before the first shovel hits the ground. It begins with the relationships established during planning, the decisions made before design is complete, and the willingness of project teams to work toward shared goals.

Those themes were front and center during the "Lessons from Leaders" breakfast hosted by DBIA – Iowa Chapter, where local construction professionals gathered to discuss what consistently drives successful design-build projects. The discussion featured perspectives from Brandon Hummel, Executive Vice President of Preconstruction at Baker Group, and Andrew Tulp, Architect at Shive-Hattery, whose experiences reflected many of the principles that continue to define successful collaborative project delivery.

Although every project presents unique challenges, one message surfaced repeatedly throughout the conversation. Successful projects are not defined by the contract that brings the team together. They are defined by how well that team aligns around common goals, communicates openly, and builds trust throughout the life of the project. 

As demand grows for faster schedules, greater cost certainty, and increasingly technical facilities, design-build project delivery continues to gain momentum because it creates an environment where informed decisions happen earlier. The lessons below synthesize the discussion into practical insights for owners, architects, engineers, contractors, and anyone considering the design-build delivery method. 

What Is Design-Build Project Delivery? 

Design-build is a project delivery method in which one entity is responsible for both design and construction. Unlike traditional delivery methods that separate these responsibilities, design-build integrates architects, engineers, contractors, specialty trades, and owners into one collaborative team from the beginning of the project.

According to the Design Build Institute of America, this integrated approach encourages collaboration, innovation, accountability, and shared responsibility throughout planning and construction.

Rather than progressing through isolated phases, project teams work together to evaluate decisions based on constructability, budget, schedule, lifecycle performance, and owner priorities before construction begins.

• Identify project risks before they impact construction.  
• Improve communication across disciplines.  
• Increase cost and schedule certainty.  
• Reduce redesign and rework.  
• Make better-informed decisions throughout the project lifecycle.  

While every project is different, the panel discussion reinforced that the greatest benefit of design-build is not simply delivering projects faster. It is creating an environment where better decisions can be made earlier, when they have the greatest impact.  

Early Collaboration Creates Better Outcomes

If there was one idea that connected nearly every topic discussed during the breakfast, it was the value of bringing the right people to the table early.

Successful design-build teams intentionally include owners, architects, engineers, specialty contractors, and builders during project planning rather than waiting until construction begins. This allows technical expertise, operational priorities, constructability, and budget considerations to inform one another instead of competing against one another later.

When project partners collaborate early, they can identify potential challenges while options remain flexible. That leads to more informed decision-making and fewer surprises during construction. 

Early collaboration also changes the nature of project conversations. Rather than asking who owns a problem, teams begin asking how to solve it together. 

Andrew Tulp summarized this mindset well during the discussion: 

"Collaborative teams, those that share ideas and create trust, are the most successful." 

That perspective reflects one of the defining characteristics of high-performing design-build teams. Innovation rarely comes from one discipline working independently. It comes from diverse expertise working toward a common objective. 

Developing Trust  

Many construction professionals talk about trust as an important part of successful projects. The discussion made it clear that trust is much more than a relationship-building exercise. It is a measurable driver of project performance. 

Brandon Hummel offered one of the morning's most memorable observations: 

"Projects move at the speed of trust." 

That statement resonated because every project depends on hundreds of decisions. When owners, designers, contractors, and trade partners trust one another, decisions happen more efficiently. Difficult conversations happen earlier. Problems are addressed before they become larger issues. 

Trust is not created by signing an agreement. It is earned through consistent actions. 

Doing what you say you are going to do. 

Communicating honestly when challenges arise. 

Being transparent about project risks. 

Following through on commitments. 

When those behaviors become part of the project culture, owners gain confidence that the team is acting in their best interest. Likewise, project partners become more willing to share ideas, raise concerns, and explore innovative solutions. 

This transparency becomes especially valuable when projects encounter evolving priorities or unforeseen conditions. 

Rather than reacting defensively, collaborative teams work together to evaluate options and make informed decisions that support the overall project objectives.
