# Performance Specification Gap in Division 12 Furnishings submittals

> Source: https://deviationcheck.com/divisions/12-furnishings/performance-specification-gap/

A measurable performance property in the submittal (rating, capacity, tolerance, efficiency) does not meet what the spec requires.

## What to look for in Division 12 Furnishings

Key performance parameters in Div 12 submittals:
- **AWI quality grade** (Economy, Custom, Premium per Architectural Woodwork Standards) - grade defines material, joinery, finish, and installation tolerances
- **Casework construction type** (flush overlay, reveal overlay, exposed face frame per AWI)
- **Countertop material properties** (thickness, Mohs hardness for stone, flexural strength, water absorption)
- **Laminate type and grade** (horizontal general purpose HGS, vertical VGS, postforming PGS, cabinet liner CLS per NEMA LD 3)
- **Edge profile type** (self-edge, applied edge, waterfall, beveled, ogee, bullnose)
- **Shade fabric openness factor** (percentage - controls glare, view, and solar heat gain; typical spec ranges 1% to 10%)
- **Light transmittance and UV blocking** (percentage)
- **Fabric weight** (oz/sy) - heavier fabric for durability, lighter for specific light filtering
- **Furniture load ratings per BIFMA** (chair rated capacity, desk static load, shelf load per lineal foot)
- **ANSI/BIFMA X5.1 compliance** (office chairs - stability, durability, structural adequacy)
- **ANSI/BIFMA X5.5 compliance** (desk/table stability and durability)
- **Drawer slide load rating** (75 lb, 100 lb, 150 lb)
- **Hinge cycle rating** (opening/closing cycles per BHMA/ANSI A156 series)
- **Countertop height** (ADA requires 34" max for accessible work surfaces; standard is 36")

## Severity

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