Submittal Package Incompleteness in Division 26 Electrical submittals

Short answer

A required submittal element (cut sheet, schedule, calculation, sample) is missing, leaving the package unreviewable as submitted. Default grade in Division 26 Electrical: Fix and Resubmit.

A required submittal element (cut sheet, schedule, calculation, sample) is missing, leaving the package unreviewable as submitted. This guide covers how it shows up specifically in Division 26 Electrical submittals.

What to look for in Division 26 Electrical

Commonly required items in Div 26 specs:

  • Single-line diagrams
  • Panel schedules with circuit assignments
  • Equipment nameplate data / catalog cut sheets
  • Wire and cable schedule
  • Lighting fixture schedule with photometric data (IES files)
  • Load calculations
  • Short-circuit study results
  • Arc flash labels / study
  • Coordination study (time-current curves)
  • Seismic anchorage calculations
  • Warranty documentation
  • O&M (Operation and Maintenance) manuals

Common examples in Division 26 Electrical submittals

An electrical submittal is unreviewable when a required engineering document is missing, and a partial package often hides the deviation that matters. Before scoring anything, confirm the package contains the following.

  • Fixture cut sheets for every type on the lighting schedule, with photometric IES files where the spec requires them.
  • The short-circuit and coordination study, including time-current curves, for the distribution equipment.
  • Voltage-drop calculations for feeders and branch circuits called out in the spec.
  • UL listing (or ETL/CSA) for each piece of equipment, marked on the cut sheet rather than assumed.
  • Panel schedules with circuit assignments and connected-load totals.
  • Single-line diagram matching the equipment actually being submitted.
  • Arc flash study and labels where NFPA 70E applies, plus seismic anchorage calculations on projects that require them.
  • Factory test reports for switchgear, generators, and UPS units.

A package missing the coordination study cannot be approved no matter how clean the cut sheets look, because selective tripping cannot be verified - return it as incomplete rather than reviewing around the gap.

How severe is it?

Default grade: Fix and Resubmit. The sub completes the package and resubmits before the PM can fully review.

Deviation Check assigns a default per category and escalates or de-escalates based on the spec, always showing its reasoning. See the Division 26 severity rules.

What the PM should do

Stamp the submittal Revise and Resubmit. Mark the deviation, return the relevant spec passage as a redline, and have the sub correct and re-send before fabrication or installation.

Frequently asked questions

What engineering documents must be present in a Division 26 electrical submittal before a reviewer can assess the distribution equipment?

The short-circuit and coordination study - including time-current curves - must be present before distribution equipment can be approved, because selective tripping cannot be verified without it. The single-line diagram must match the equipment actually being submitted. Panel schedules with circuit assignments and connected-load totals, arc flash study and labels where NFPA 70E applies, and factory test reports for switchgear, generators, and UPS units are also required. A package missing any of these should be returned as incomplete rather than reviewed around the gap.

Why are IES photometric files required in a Division 26 lighting submittal rather than just the fixture cut sheet?

IES files allow the engineer of record to verify that the proposed fixture actually meets the foot-candle levels and uniformity ratios specified for the space - the cut sheet image and lumen output alone do not. Without IES files, photometric compliance cannot be confirmed. Voltage-drop calculations for feeders and branch circuits called out in the spec are similarly required for completeness, and UL listing must be marked on the cut sheet rather than assumed from the manufacturer's reputation.
