Incorrect Statement for a First-Class Building

The incorrect statement for a first-class building is option 'A': the minimum height of rooms should be 3.1 meters.

Explanation


  • Option A: Minimum Height of Rooms

  • The statement in option A is incorrect. The minimum height of rooms in a first-class building should not be specified as 3.1 meters. The height of rooms in a building can vary depending on the purpose of the room and the building regulations. However, a general standard for the minimum height of rooms is usually around 2.4 to 2.7 meters. Therefore, the statement in option A does not align with the typical requirements for a first-class building.


  • Option B: Damp Proofing Coarse

  • The statement in option B is correct. The damp proofing coarse, if made of cement mortar, should have a minimum thickness of 2.5 cm. This is necessary to prevent moisture from seeping into the walls and causing dampness issues.


  • Option C: Inside and Outside Plaster

  • The statement in option C is correct. The inside and outside plaster of a first-class building should have a minimum thickness of 12 mm. Plastering helps to provide a smooth finish to the walls and protects them from damage.


  • Option D: Mosaic Flooring

  • The statement in option D is correct. Mosaic flooring must be provided in a first-class building, including the staircase. Mosaic flooring is a type of decorative flooring that adds a touch of elegance and enhances the aesthetic appeal of the building.



To summarize, the incorrect statement for a first-class building is option A, which states that the minimum height of rooms should be 3.1 meters. The correct minimum height for rooms in a first-class building may vary, but it is typically around 2.4 to 2.7 meters.
