North Carolina Building Contractor License Practice Exam

Under what circumstances is it allowed to place construction loads on unbridged joists?

1. If they have additional bracing

2. If it is approved by an engineer

3. It is not allowed under any circumstances

4. If the load is under 500 pounds

The correct answer is: It is not allowed under any circumstances

Placing construction loads on unbridged joists is a critical safety concern in building construction. The correct response situates itself within the understanding of structural integrity and safety standards that govern construction practices. Unbraced joists lack the necessary support and lateral stability to safely withstand additional loads. Bridging between joists serves to create stability, reducing the potential for lateral movement and buckling under load. In cases where joists are unbraced, they are not designed to bear weight safely, which can lead to structural failure or catastrophic damage. Hence, regardless of other potential conditions, placing construction loads on unbridged joists is not permissible, emphasizing the importance of following established safety protocols and engineering principles in construction. This rationale elucidates why the answer indicating that such actions are not allowed under any circumstances is accurate. It underscores the necessity of maintaining structural integrity, adhering to safety guidelines, and ensuring that construction methods conform to engineering standards.
