How does a change in project requirements during the design phase affect construction costs?

A change in project requirements during the design phase can lead to increased costs due to the need for redesign efforts. When changes occur, architects and design teams may have to reevaluate the initial design, which often involves additional work, such as developing new drawings, specifications, and potentially updated engineering analyses. These tasks require time and resources, which directly translate into higher costs.

Moreover, changes in project requirements can affect materials, construction methods, and even project timelines. For instance, if a client decides to modify the scope of the project or enhance specific features, it could require different or more expensive materials, which can further escalate costs. Additionally, if the redesign delays the overall schedule, it may lead to further expenses related to extended labor or construction time.

Understanding this dynamic is crucial for architects, as it highlights the importance of clear communication with clients during the design phase to manage expectations and costs effectively.
