Red Seal Ironworker (Reinforcing) Practice Exam

When should rebar be inspected before a concrete pour?

1. Only after the pour has started

2. Always prior to the pour to ensure correct placement and conditions

3. Inspection is not necessary if visible

4. After concrete curing is complete

The correct answer is: Always prior to the pour to ensure correct placement and conditions

Inspections of rebar prior to a concrete pour are essential to ensure that all reinforcing steel is correctly placed, secure, adequately spaced, and meets design specifications. This pre-pour inspection serves several critical purposes, including verifying that the rebar is the correct type and size, checking for any damage, and ensuring compliance with project specifications and building codes. Additionally, this inspection allows for any necessary adjustments to be made before the concrete is poured, which can help avoid issues that may arise during the curing process or in the structural integrity of the finished product. Conducting inspections only after the pour has started, as suggested in one of the other options, doesn’t allow for corrective measures to be taken if issues are found. Similarly, ignoring the need for inspection based on visibility can lead to problems that are not immediately apparent, affecting the strength and durability of the concrete structure. Finally, waiting until after the concrete curing is complete would be too late to address any placement issues, making pre-pour inspections crucial for maintaining construction quality.
