Explanation:
In masonry construction, openings such as doors and windows are created by removing bricks or blocks from the wall. When calculating the amount of materials required for the construction, it is important to take into account the size of these openings. However, if the area of the opening is very small, it may not be necessary to make any deductions from the total amount of materials required.
The correct answer is option D, which states that no deductions need to be made if the area of the opening does not exceed 0.10 m2. This means that if the size of the opening is smaller than this, the total amount of bricks or blocks required for the wall can be calculated based on the total surface area of the wall without subtracting any additional material for the opening.
Why is this important?
Making deductions for small openings may seem like a minor detail, but it can have a significant impact on the overall cost and time required for the construction project. By avoiding unnecessary deductions, builders can save time and money, and ensure that the project is completed efficiently.
Conclusion:
In summary, when constructing masonry walls, it is important to take into account the size of any openings. If the area of the opening is smaller than 0.10 m2, no deductions need to be made when calculating the total amount of materials required for the wall. This can help to save time and money and ensure that the project is completed efficiently.
