Division 27 Communications
Submittal Package Incompleteness in Division 27 Communications submittals
Short answer
A required submittal element (cut sheet, schedule, calculation, sample) is missing, leaving the package unreviewable as submitted. Default grade in Division 27 Communications: 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 27 Communications submittals.
What to look for in Division 27 Communications
Commonly required items in Div 27 specs:
- Cabling system product data sheets (cable, connectors, patch panels, faceplates)
- Manufacturer system warranty documentation and installer authorization letter
- Telecommunications room layout drawings (rack elevations, equipment placement)
- Cable pathway layout and fill calculations per TIA-569
- Labeling plan per TIA-606
- Grounding and bonding plan per TIA-607
- Fiber optic link loss budget calculations
- Wireless site survey and predictive heat map (AP placement, coverage, channel plan)
- DAS RF design documentation (coverage maps, signal strength predictions)
- Test equipment specifications and calibration certificates
- Sample test reports (permanent link or channel per TIA-568)
- AV system signal flow diagrams and equipment rack elevations
- Paging/intercom zone layout and speaker coverage plan
- Project-specific installation details (firestop, seismic bracing, support methods)
- Training plan for owner's personnel
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 27 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 Division 27 Communications submittal items are most often missing, making the package unreviewable as submitted?
Telecommunications room layout drawings with rack elevations and equipment placement are frequently omitted, leaving the reviewer unable to confirm rack unit capacity or power density. Fiber optic link loss budget calculations are also commonly absent - without them, the reviewer cannot verify the submitted fiber type and strand count will meet bandwidth requirements at the specified distances. Both gaps require resubmission before the technical review can proceed.
Why does a Division 27 Communications package need a wireless site survey and predictive heat map before the PM can complete the review?
Without the predictive heat map showing AP placement, coverage levels, and channel plan, the reviewer cannot assess whether the submitted AP model and quantity meet the specified dBm threshold at the cell edge. The heat map is the calculation that ties the product data sheet to the actual space. Submitting product cut sheets alone, without the RF design documentation, leaves the performance case incomplete and blocks sign-off.
