What should be done to walls or floors that have been damaged before demolition work starts?

Before demolition work begins, it is essential to shore and brace walls or floors that have been damaged. This practice is vital for ensuring the safety and stability of the structure during the demolition process. Shoring and bracing provide temporary support to the compromised elements, preventing unexpected collapses or further damage, which could pose risks to workers and the surrounding environment.

Leaving damaged walls or floors as they are can lead to dangerous situations where the integrity of the structure is uncertain. Simply reinforcing them with concrete may not adequately address the issues present or provide the immediate support required during demolition. Furthermore, completely demolishing these areas before assessing their condition could lead to additional complications and safety hazards.

In summary, shoring and bracing is the most responsible approach to ensure safety and maintain control over the demolition process, allowing workers to operate in a secure environment.
