Question

Which type of temporary supporting structure can be used in case of rebuilding the lower part of a load bearing wall at ground floor above plinth level?

• A. Dead Shore
• B. Pit Underpinning
• C. Flying Shore
• D. Needle Scaffolding

Hint:

Use Dead Shores to provide temporary vertical support during structural repair or rebuilding of lower walls.

Answer 1

The Correct Option is B

A dead shore is a temporary supporting structure used to support a load-bearing wall or other parts of a structure when the foundation or lower part is being repaired or rebuilt. It is particularly useful when work is being done below the ground floor level, as it provides vertical support to the wall while construction activities take place.
Why the other options are incorrect:
- Pit Underpinning (B) is a technique for strengthening foundations, not specifically for vertical support during rebuilding.
- Flying Shore (C) is used for laterally supporting a wall, typically during reconstruction.
- Needle Scaffolding (D) is used to temporarily support the load of the building during window or door repairs, not for wall rebuilding.
Thus, the correct answer is (A).
