IS 1200:2000 (Part 27) is the Indian Standard (BIS) for method of measurement of building and civil engineering works, part 27: earthwork done by mechanical appliances. This part of IS 1200 establishes the method of measurement for earthwork operations executed using mechanical appliances like excavators, scrapers, and dozers. It is used by estimation engineers and quantity surveyors to accurately measure quantities for billing, contracting, and cost estimation in large-scale civil engineering projects.

| 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 |
