Red Seal Carpenter Practice Exam

When placing longitudinal and temperature steel for an exterior concrete stair, how is the size of steel required determined and where to tie the steel to achieve proper concrete coverage all around?

1. Refer to the architectural drawings.

2. Refer to the largest scale architectural detail that shows the stair.

3. Refer to the structural drawings.

4. Refer to the largest scale structural detail that shows the stair.

The correct answer is: Refer to the largest scale structural detail that shows the stair.

To determine the size of steel required for an exterior concrete stair, it is important to refer to the largest scale structural detail that shows the stair. This is because the structural detail will provide specific information on the load capacity and structural requirements for the stair. Referring to the architectural drawings or largest scale architectural detail may not provide accurate sizing information for the steel as it typically focuses on the overall design and aesthetics of the stair. Additionally, simply following the architectural drawings may not ensure proper concrete coverage all around as these drawings may not take into account the structural considerations necessary for the steel placement. Therefore, it is important to refer to the structural drawings and largest scale structural detail to accurately determine the size of steel needed and where to tie it for proper concrete coverage.
