Short-circuit coordination before energization
Data center Commissioning lead
Failure mode
A short-circuit coordination study was built from stale assumptions because key submittal and equipment-rating details were not locked down early enough.
Value at risk
Approximately $150k of rework / damage exposure and at least 2 weeks of schedule risk.
Root cause chain
Study assumptions were treated as final.
Electrical gear and submittal information was not verified early enough.
KAIC and equipment-rating implications were discovered too late.
Late discovery created rework and schedule exposure.
Preventive action
Before energization pressure starts, verify the study against approved submittals, actual equipment ratings, KAIC requirements, and current electrical gear data.
Best workflow moments
- Before energization
- Electrical commissioning readiness review
- Before final switchgear / distribution equipment acceptance
- MEP coordination closeout
