Which of the following is NOT a major factor when choosing a delivery method for an owner?

When selecting a delivery method for a project, factors such as schedule, project complexity, and potential changes are critical considerations because they directly impact how the project is executed, managed, and delivered.

Schedule is essential as it dictates the timing and sequence of activities, influencing the overall timeline. Project complexity refers to the intricacies of the project, such as the scope of work, technical challenges, and the coordination required among various stakeholders. Changes in project requirements are inevitable and must be managed effectively to avoid delays and cost overruns.

In contrast, the location of the contractor's headquarters, while it may have some logistical implications, is not a major factor in the decision-making process for delivery methods. This aspect might influence local resource availability or travel considerations, but it doesn't fundamentally affect the strategic approach to delivering the project, such as the choice between design-bid-build, design-build, or other delivery methods. Thus, it is less critical compared to the other factors when determining the appropriate delivery method for a project.
