Answer :
The correct answer is:
- All of the above
Explanation:
1. **Vertically aligned:** Shoring for concrete operations should be vertically aligned to ensure stability and proper support for the concrete being poured. This alignment helps distribute the weight of the concrete evenly, preventing any structural issues during the pouring and curing process.
2. **Braced in perpendicular and diagonal directions:** Bracing the shoring system in both perpendicular and diagonal directions is crucial to enhance its stability and prevent any lateral movements. Perpendicular bracing helps to counteract horizontal forces, while diagonal bracing provides additional support to resist potential sway or buckling.
3. **Designed by a qualified designer:** It is essential that the shoring system for concrete operations is designed by a qualified designer or engineer who has the expertise and knowledge to ensure that the structure meets safety standards and can withstand the loads it will be subjected to. A qualified designer will consider various factors such as the weight of the concrete, site conditions, and applicable regulations to create a structurally sound shoring system.
By ensuring that the shoring for concrete operations is vertically aligned, braced in perpendicular and diagonal directions, and designed by a qualified professional, the integrity and safety of the concrete construction process are maintained, reducing the risk of accidents or structural failures.
