Workface Availability vs Trade Density
Segment work areas into controlled production zones with defined sequencing to eliminate trade interference and restore effective workface availability.

Business Context
Accelerated projects often attempt to increase production by placing several trades in the same areas simultaneously. Although this increases the number of active workers, competing crews may require the same access routes, work surfaces, equipment, or temporary facilities, reducing effective workface availability.
Real Estate & Construction TRIZ Resolution
Workfaces should be treated as controlled production resources. Areas can be divided into smaller zones, trades assigned according to defined production sequences, and incompatible activities separated by location or time. Zone release criteria can ensure that each crew receives a genuinely workable area.
Applicable TRIZ Principles
Principle 1 – Segmentation divides floors or work areas into independently controlled production zones.
Principle 19 – Periodic Action separates incompatible trades through scheduled work periods.
Principle 3 – Local Quality assigns different production arrangements according to individual zone conditions.
Expected Outcome
Greater effective workface availability
Reduced trade interference
Higher labor productivity
More predictable workflow
Decision Indicators
Early indicators include:
Several trades occupy areas without achieving expected output.
Workers repeatedly relocate because other activities block access.
Finished work is damaged by subsequent trades.
Increasing worker density reduces installed quantities per labor hour.
Schedule acceleration depends mainly on overlapping more activities.
