Understanding Construction Project Delivery Methods
Your project delivery method defines how owners, designers and contractors work together, how responsibilities and risk are allocated, and when construction expertise enters the process. Those choices shape when important decisions are made and how much flexibility the team has from planning through completion.
Choosing the right approach can influence cost, schedule, collaboration and long-term project success before construction even begins. But the best delivery method is not the one we prefer—it is the one that best supports your goals.

Carl A. Nelson & Company has decades of experience delivering projects across all major construction delivery methods. Our role is not to promote a single approach, but to help Owners understand their options, evaluate tradeoffs, and select the method that best supports cost certainty, schedule control, risk allocation, and long-term success.
Why delivery method matters
Delivery methods don't simply determine contracts — they influence when expertise is introduced, how decisions are made, and how much flexibility owners have while changes are still inexpensive.
One of the most consequential differences between delivery methods is when construction expertise is brought into the process—and how much influence it has when key decisions are made.
In traditional General Contracting, the builder’s influence is largely limited to execution after design is complete. In Design-Build and Construction Management, construction expertise can inform cost, schedule, and constructability decisions earlier—when those decisions have the greatest impact.
Common construction delivery methods
-
Design-Build
A single point of responsibility for design and construction, aligning accountability and decision-making from concept through completion. -
Construction Management
A collaborative delivery method where the construction manager provides pre-construction leadership and construction-phase coordination, with roles defined by contract structure. -
General Contractor
A traditional delivery approach where construction is executed based on completed design documents, typically under a fixed-price contract.
Constraints versus choices
In practice, delivery method selection may be influenced by organizational policies, procurement rules, or statutory limitations—particularly for public Owners.
Even within those constraints, Owners often have more flexibility than they realize. Understanding what is possible, what is required, and what tradeoffs accompany each option allows project teams to make informed decisions rather than default ones.
Our approach
No delivery method is automatically the right choice. Our role is to help owners understand the tradeoffs, then apply construction expertise where it creates the greatest value.
Deliver Value. Build Trust. Repeat.
That means helping Owners understand delivery options early, applying construction expertise where it can add the most value, and leading projects with clarity, accountability, and disciplined execution—no matter the contract form.
