Which of the following is a common form of construction risk?

Design errors are considered a common form of construction risk because they can significantly impact the project's overall success, including cost, schedule, and quality. Errors in design can lead to unforeseen issues during construction, necessitating changes that might not only delay progress but also incur additional expenses. Additionally, design errors can affect the functionality and safety of the completed project, posing further risks. Identifying and mitigating design errors early in the project lifecycle is essential to managing construction risk effectively.

While client satisfaction, successful project completion, and regulatory approvals are important factors in a construction project, they do not inherently represent risks in the same way that design errors do. Instead, client satisfaction is an outcome influenced by various project factors; successful project completion is the desired goal, and regulatory approvals are necessary steps that must be managed, but they do not represent direct risks like design errors do.
