Key Methodologies & Processes

Fundamental Tracking Methods

Daily Output Measurement

The foundation of productivity tracking lies in establishing clear, measurable benchmarks for different trades:

Masonry Work:

• Standard mason output: 250-300 bricks per day
• Factors affecting output: brick size, mortar mix, wall height, weather conditions

Shuttering/Formwork:

• Experienced carpenter: 25-35 square meters per day
• Variables: complexity of structure, reuse of shuttering material, crew experience

These benchmarks align with IS 7272 (Work Measurement) standards, which provide nationally recognized productivity norms for various construction activities.

Gang Productivity Analysis

Optimal crew composition significantly impacts overall productivity:

Brickwork Gang Composition:

• Ideal ratio: 1 mason + 2 helpers for 10m³ brickwork daily
• Helper responsibilities: material supply, mortar mixing, cleaning
• This ratio ensures continuous mason engagement without material delays

Time-Motion Studies

Modern construction sites use video analysis combined with chronocycle graphs to study repetitive tasks:

Implementation Process:

1. Record 2-3 complete work cycles on video
2. Break down each activity into micro-elements
3. Identify non-value-adding movements
4. Calculate optimal time for each element
5. Establish improved work methods

Activity Sampling (Pocket Watch Method)

This statistical technique involves random 10-minute observations throughout the day:

Calculation Method:

• Total observations: 50 per day
• Productive work observations: 35
• Productivity percentage: (35/50) × 100 = 70%
