Study Notes
Measurement Accuracy
- Accuracy in measurement is crucial, especially when material costs are high, requiring precise calculation of quantities.
- When rates are low, less precise measurements are acceptable.
- Wall masonry (paid per cubic meter): slight measurement deviations have minimal impact on the total cost.
- Width and thickness variations in walls will affect the total cost significantly
Metric System Units
- Millimeters (mm) for very small dimensions
- Centimeters (cm) for smaller dimensions
- Meters (m) for larger dimensions
- Kilometers (km) for distances
Dimensions for Construction Materials
| S.No. | Material | Dimensions |---|---| | 1 | Bricks, stone blocks | All dimensions in cm | 2 | Files, slates, wall board, glass panels, A.C sheets | Length and breadth in cm or m, Thickness in mm | 3 | Doors, windows | Height and breadth in cm or m | 4 | Door/Window parts (panels, shutters)| cm or mm, Length in m and cross-sectional dimensions in cm or mm. | 5 | Timber | Length in m and cross-sectional dimensions in cm or mm. | 6 | Masonry (brickwork, stone masonry) | Length and height in m, Thickness or breadth in cm | 7 | Cement concrete, lime concrete, R.C.C flooring | Length and breadth in m, Thickness in cm.
