How much earth can one labourer excavate per day?

Approximately 3.50 cubic meters in ordinary soil per 8-hour day (Table 1).

What is the daily output for a team doing brickwork in the superstructure?

1.00 cubic meter per day for a team (1 Mason, 2 Mazdoors, 1/2 Bhishti) using cement mortar 1:6 (Table 4).

Do these constants apply to machine-based work?

No, these constants are primarily for manual labour. Clause 4 notes that mechanization is a major factor requiring adjustment of these values.

Which states are covered under the 'North Zone'?

As per Appendix A: Jammu & Kashmir, Punjab, Haryana, Himachal Pradesh, Rajasthan, Uttar Pradesh, and the Union Territories of Delhi and Chandigarh.

This standard provides recommended labour output constants for various building construction activities, specifically for the North Zone of India. It serves as a crucial guide for project managers, quantity surveyors, and estimators for preparing realistic schedules, manpower planning, and cost estimates.

Recommendation for Labour Output Constants for Building Work, Part I: North Zone

Quick Reference Values

Earth excavation in ordinary soil per mazdoor3.50 m³/day

Brickwork in cement mortar 1:6 in superstructure per team1.00 m³/day

Mixing PCC 1:4:8 manually per team3.00 m³/day

12 mm cement plaster 1:6 per team8.00 m²/day

Reinforcement bending and binding for foundations per team1.00 quintal/day

Practical Notes

These constants are for an 8-hour working day and represent an average output under normal conditions; they must be adjusted for site-specific factors like accessibility, weather, labour skill, and mechanization.

The 'North Zone' is defined in Appendix A and includes states like Delhi, Punjab, Haryana, UP, Rajasthan etc. Using these constants in other zones will lead to inaccurate estimates.

The constants are a baseline. It is best practice to develop a company-specific database of productivity by tracking actual output on projects.
