Performance Specification Gap in Division 09 Finishes submittals

By Deviation Check Editorial Team. Last reviewed June 1, 2026.

Short answer

A measurable performance property in the submittal (rating, capacity, tolerance, efficiency) does not meet what the spec requires. Default grade in Division 09 Finishes: Blocker.

A measurable performance property in the submittal (rating, capacity, tolerance, efficiency) does not meet what the spec requires. This guide covers how it shows up specifically in Division 09 Finishes submittals.

What to look for in Division 09 Finishes

Definition. A measured property of the submitted product fails to meet a spec-required threshold.

Detection signals. Spec states a numeric threshold or rated class (Noise Reduction Coefficient at or above X, fire rating Class A, slip resistance at or above Y, abrasion class Z, recycled-content percentage); submittal data sheet shows a value that does not meet the threshold.

Default severity. Blocker.

Example. Spec: "Noise Reduction Coefficient (NRC) at or above 0.70." Submittal data sheet: NRC = 0.65.

Common examples in Division 09 Finishes submittals

Performance gaps in Division 09 are the most quantifiable deviation type and the easiest to verify on paper - the spec states a number or rated class, the data sheet states a value, and they either meet or they do not.

  • Acoustic ratings - Noise Reduction Coefficient (NRC) and Ceiling Attenuation Class (CAC) on acoustical ceilings and panels - against the spec minimum; a tile at NRC 0.55 where 0.70 was required is a clear miss.
  • Fire performance - flame spread and smoke developed by ASTM E84 class (Class A vs B), and floor-covering critical radiant flux per ASTM E648 - against the stated class.
  • Slip resistance (dynamic coefficient of friction per ANSI A326.3) on tile and resilient flooring where the spec sets a wet or barrier-free threshold.
  • Abrasion and wear ratings - PEI class on porcelain tile, wear-layer thickness (mils) on resilient and LVT, and Taber abrasion on coatings.
  • Recycled content, VOC limits, and certification thresholds (FloorScore, Greenguard Gold, CDPH) stated as a percentage or limit the product must meet.
  • Hardness, gloss, and dry-film-thickness values on paints and high-performance coatings against the product data.
  • Light reflectance value (LRV) where the spec sets a minimum for ceilings or wall finishes.

Because these are numbers, a performance gap is rarely a judgment call - if the data sheet reads under the spec threshold it is a Blocker, and catching it on the submittal avoids a tear-out after the product is installed and tested.

How severe is it?

Default grade: Blocker. Always a Blocker when the gap touches life-safety or structural performance.

Deviation Check assigns a default per category and escalates or de-escalates based on the spec, always showing its reasoning. See the Division 09 severity rules.

What the PM should do

Treat this as a hold. Do not approve the submittal until the sub resolves it, either by providing the specified product and documentation or by routing an approved substitution or or-equal request. Return the relevant spec passage to the sub as a redline.

Frequently asked questions

What performance properties are most commonly flagged as gaps in Division 09 Finishes submittals?

Common gaps include Noise Reduction Coefficient ratings, ASTM E84 fire rating Class A flame spread, slip resistance values, abrasion class, and recycled-content percentages. A typical example is a spec requiring NRC at or above 0.70 while the submitted data sheet shows NRC = 0.65. Any numeric threshold in the spec that the data sheet does not meet is a Blocker.

Why is a performance gap in a Division 09 Finishes submittal always classified as a Blocker rather than a lesser severity?

Because the submitted product is demonstrably out of spec by a measured value, not just a documentation gap. When the gap touches life-safety or structural performance - such as fire rating Class A flame spread per ASTM E84 - the Blocker stands regardless of how small the numeric difference appears. Fabrication or installation cannot proceed until the product meets the specified threshold.
