Question
Which of the following statements is/are correct with respect to temporary structures during construction?
Temporary Construction Structures Analysis
Statement 1: Centering Functionality
Centering refers to the temporary framework used to support formwork during the construction of elements like arches, domes, and slabs. Its primary role is to hold the structure in place until it cures and gains sufficient strength to support itself. Therefore, this statement accurately describes the function of centering.
Statement 2: Scaffolding Purpose
Scaffolding provides essential elevated working platforms and access for construction workers. It is crucial for tasks like masonry, plastering, and facade work, allowing workers to operate safely at different heights. This statement correctly defines the purpose of scaffolding.
Statement 3: Shoring's Role
Shoring involves providing temporary support to unstable soil, trenches, or adjacent structures to prevent collapse during excavation or construction. Its function is structural support, not preventing dampness. Dampness prevention is achieved through waterproofing methods. Thus, this statement is incorrect.
Statement 4: Underpinning Application
Underpinning is a technique used to strengthen, repair, or deepen existing foundations. It ensures the stability and load-bearing capacity of a structure, often when original foundations are inadequate or soil conditions change. This statement correctly describes underpinning.
Conclusion on Correct Statements
Based on the analysis:
- Statement 1 (Centering) is correct.
- Statement 2 (Scaffolding) is correct.
- Statement 3 (Shoring) is incorrect.
- Statement 4 (Underpinning) is correct.
