Is wire "ladder" reinforcing mandated in every third course of blockwork?

1. Yes

2. No

3. Only in specific building codes

4. Only for structural integrity

The correct answer is: No

The correct answer indicates that wire "ladder" reinforcing is not mandated in every third course of blockwork. This is because the requirement for such reinforcement can vary based on several factors including the structural requirements of the building, local building codes, and specific engineering calculations. Not all construction projects need this reinforcement; it is often used in instances where additional strength or stability is necessary, particularly in areas prone to seismic activity or in large structural walls. Local building codes take precedence, which means that while some jurisdictions may require the reinforcement in certain situations, it is not a blanket rule covering every third course for all projects without consideration. Furthermore, the need for wire "ladder" reinforcing could depend on the intended use of the structure, wall height, and other design specifications rather than being a universal requirement. Thus, the response that it is not mandated across all blockwork is accurate.
