Understanding Construction Project Delivery Methods

Project and Ownership Type Affect Which Delivery Method is Right for You

One of the first decisions an owner must make after choosing to build or remodel a building is to select a delivery method for the project. The graphics below, and the pages they link to, outline each of the construction project delivery methods offered by Carl A. Nelson & Company. Those include:

  • Design-Build
  • Construction Management Agency
  • Construction Management at-Risk
  • General Contractor

Depending on your Ownership type — public or private — your ability to access some delivery methods may be limited by legal restrictions that vary from state to state. 

Generally, public owners are limited to Construction Management Agency or General Contracting, although attitudes and laws are changing across the country toward public use of Design-Build delivery. 

Private owners have a broader choice of delivery methods, and can choose Design-Build, Construction Management at-Risk or General Contracting, where we are able to self-perform much of the work.

One of the most impactful consequences of choosing a delivery method is whether the Owner will have the opportunity to take advantage of the builder's experience on cost, schedule and constructability with respect to architectural and engineering design. 

In design-build and construction management delivery, the design-builder or construction manager is involved in the pre-construction phase of the project, and thus able to perform what is known as value engineering — reviewing the design to ensure the project is buildable as designed; can be completed on the anticipated schedule and within the available budget; ensures the Owner is getting the most value from its investment; and prevents costly or inefficient maintenance for the life of the project. The earlier in the planning process that effort is brought to bear, the greater the impact it can have on cost and schedule.
