Which of the following is a common cause of construction defects?

Poor materials and workmanship are frequently identified as common causes of construction defects because they directly impact the quality and durability of the finished project. When inferior materials are used or when the work is executed improperly, the integrity of structures can be compromised, leading to issues such as structural failures, leaks, or overall aesthetic problems.

In contrast, high-quality materials would generally contribute to fewer defects by providing better performance and resilience. Regularly scheduled inspections serve as preventative measures to catch potential issues early and ensure compliance with building standards, thus reducing the likelihood of defects. An experienced labor force is more likely to follow best practices and apply their skills effectively, which also helps in minimizing construction defects. Therefore, the choice highlighting poor materials and workmanship is aligned with industry observations regarding the origins of construction-related issues.
