š Understanding Measurement of Brickwork
According to the Indian Standard IS 1200 (Part 3), the standard method for measuring most brickwork (like thick walls, columns, etc.) is in cubic metres (mĀ³). This accounts for all three dimensions: length, width, and height.
However, for certain types of thin brickwork where the thickness is fixed and small, it is more practical and conventional to measure the work in square metres (mĀ²), specifying the thickness separately.
š¬ Detailed Analysis of the Options
D. All options are correct
This is the correct answer. All the listed items are specific cases where the standard practice, as outlined in IS 1200, is to measure the brickwork in square metres rather than cubic metres.
A. Honey comb brick work
This is a type of brickwork with voids, often used for ventilation or decorative screens. Since its thickness is fixed and the structure is open, it is measured in square metres (mĀ²), stating the thickness.
B. Brick flat soling
This is a single layer of bricks laid flat, typically under a foundation. As it is a surface layer with a fixed, single-brick thickness, it is always measured by its area in square metres (mĀ²).
C. Half brick walls or the partition
A half-brick wall (thickness of approx. 10 cm or 4 inches) is a thin partition wall. IS 1200 specifies that walls of one brick thickness or less should be measured in square metres (mĀ²).
š Summary: Units of Measurement for Brickwork (IS 1200)
| Type of Work | Standard Unit | Reason |
|---|---|---|
| Thick Walls, Columns, etc. | Cubic Metre (mĀ³) | All 3 dimensions are significant. |
| Half Brick Walls | Square Metre (mĀ²) | Thickness is small and fixed. |
| Brick Flat Soling | Square Metre (mĀ²) | It is a single surface layer. |
| Honeycomb Brickwork | Square Metre (mĀ²) | Thin profile with voids. |
š” Study Tips
- Think "Thin" = mĀ²: As a general rule for quantity surveying, if a brickwork item is thin and has a fixed thickness (like a partition or a single layer), it's measured by its area.
- Think "Thick/Bulk" = mĀ³: If the item is substantial and has significant volume (like a main structural wall), it's measured by its volume.
- Memorize the Exceptions: The three most common exceptions to cubic measurement are half-brick walls, soling, and honeycomb work.
