IS 1200:2000 (Part 25) is the Indian Standard (BIS) for method of measurement of building and civil engineering works, part 25: tunnelling. IS 1200 Part 21 provides the standard method of measurement for woodwork and joinery in building and civil engineering works. It is predominantly used by quantity surveyors and civil engineers to prepare bills of quantities (BOQ), estimate costs, and clear contractor bills for timber doors, windows, partitions, and frames.

| Parameter | IS Value | International | Source |
|---|---|---|---|
| Standard Lead in Base Rate | 30 metres included in excavation item. | Not applicable. Haulage is measured separately from excavation. | CESMM4 |
| Standard Lift in Base Rate | 1.5 metres included in excavation item. | Not applicable. Excavation is often measured in depth ranges (e.g., 0-2m, 2-4m). | CESMM4 |
| Bulk Excavation Unit | Cubic Metre (m³) | Cubic Metre (m³) | CESMM4 / NRM 2 |
| Surface Dressing Unit | Square Metre (m²) | Square Metre (m²) | NRM 2 |
| Deduction for Voids (e.g., pipes) | No deduction for voids up to 0.1 m² in cross-section. | Deductions made for voids > 0.05 m³ in volume (not cross-section). | NRM 2 |
| Measurement of Excavation | Net dimensions of the final void created. | Net dimensions of the final void created. | CESMM4 |
| Measurement of Filling | Net volume of the space to be filled (final compacted volume). | Net volume of the space to be filled (final compacted volume). | NRM 2 |
