Which type of delay is classified as being beyond the control of both the contractor and the owner?

The type of delay classified as being beyond the control of both the contractor and the owner is known as "Acts of God." These delays typically refer to unforeseen natural events that can impact the progress of a project, such as hurricanes, floods, earthquakes, or other extreme weather conditions. Since these events are not caused by either party and cannot be anticipated or mitigated in a conventional manner, they are considered excusable delays.

Understanding this classification is crucial for project management because it helps in determining accountability and responsibility for delays and whether extensions of time or compensation are warranted. Recognizing that these events are external to the control of both contractors and owners provides a framework for managing risks associated with natural disasters in project schedules.

In contrast, owner-controlled delays arise from decisions or actions by the owner that impede project progress, contractor-controlled delays stem from issues within the contractor’s ability to execute work, and logistical delays relate to complications in the supply chain or transport of materials, which may be managed or foreseen.
