Labour costs are typically 30-40% of Indian construction project cost (similar to materials). Pricing labour into rate analysis + tender bids requires per-activity productivity assumptions — how many m² / m³ / units a crew can produce per shift.
The Labour Productivity Sheet is the project-specific or company-specific reference of productivity norms for each trade × activity combination. It's used in: - Pre-tender estimation — to compute labour cost component of rate analysis - Resource planning — to determine crew sizes for schedule - Performance benchmarking — actual vs benchmarked productivity - Cost control — productivity drift signals supervision issues
Without standardized productivity norms, each rate analysis uses different assumptions → inconsistent pricing → unreliable cost estimates.
Concrete work: - Cast-in-situ slab (M25): 5-8 m³/day per crew of 6 (1 mason + 5 helpers) - Cast-in-situ column (M25): 2-4 m³/day per crew - RMC placement: 8-15 m³/day per pump + crew
Masonry: - Brickwork (1st class) 230 mm thick: 2.5-4 m³/day per mason - AAC block work 200 mm: 3.5-5 m³/day per mason - Stone masonry: 0.8-1.5 m³/day per skilled crew
Plaster / Finishes: - Internal plaster 1:4 (12-15 mm): 12-18 m²/day per mason - External plaster 1:6 (15-20 mm): 8-14 m²/day per mason (with scaffold) - Floor tiling: 8-12 m²/day per skilled tiler - Painting (3 coats): 15-25 m²/day per painter
Reinforcement: - Cutting + bending: 200-400 kg/day per fabricator - Placement + tying: 600-1200 kg/day per fixer crew
Earthwork: - Hand excavation (soft soil): 2-3 m³/day per labourer - Backfill + compaction: 5-8 m³/day per labourer
Productivity factors (multiply baseline): - Working at height: × 0.7 (lower productivity) - Restricted access: × 0.6-0.8 - Hot weather (> 35°C): × 0.8-0.9 - New / untrained crew: × 0.5-0.7 - Experienced crew + good supervision: × 1.1-1.3 - Bulk pours (large slabs): × 1.2-1.4 (economies of scale)
1. No project-specific norms — using generic industry numbers without site-condition adjustment. Rate analysis becomes optimistic. 2. Old norms used — labour productivity changes with technology + crew capabilities; norms not updated. 3. No actual measurement — actual productivity never measured + compared to norm; drift undetected. 4. Crew sizes wrong — over-resourcing wastes labour cost; under-resourcing causes delays. 5. Wrong crew composition — too many skilled / too many unskilled; wrong skill mix lowers productivity. 6. No supervision factor — productivity drops 30-50% without active supervisor; not in rate analysis. 7. Weather + access not factored — actual conditions worse than estimated baseline; rate analysis under-prices. 8. No benchmarking — different projects use different productivity assumptions; no learning across projects.
