Parallel Work vs Interface Congestion
Sequence construction zones by spatial and temporal separation to eliminate shared-resource conflicts before they generate safety or schedule failures.

Business Context
Executing activities concurrently can shorten the construction schedule, but excessive parallel work creates competition for space, cranes, access routes, permits, materials, supervision, and system interfaces.
Green Field Industrial Projects TRIZ Resolution
Parallelize activities that are functionally and spatially independent while separating conflicting work by area, elevation, system, or time. Manage shared interfaces as explicit constraints within the construction sequence.
Applicable TRIZ Principles
Principle 1 – Segmentation divides construction into independent work zones and packages.
Principle 17 – Another Dimension separates activities spatially or temporally.
Principle 20 – Continuity of Useful Action keeps compatible work progressing without unnecessary interruption.
Expected Outcome
Greater useful concurrency
Reduced work-front congestion
Higher productivity
More reliable schedule performance
Decision Indicators
Early indicators include:
Multiple crews compete for the same access.
Work is repeatedly stopped because of adjacent activities.
Crane and lifting conflicts increase.
Parallel work creates frequent permit conflicts.
Additional work fronts reduce rather than increase installed progress.
