# Manufacturer or Product Substitution in Division 25 Integrated Automation submittals

> Source: https://deviationcheck.com/divisions/25-integrated-automation/manufacturer-substitution/

The submittal proposes a different manufacturer or product than the spec names, without an approved or-equal or substitution request.

## What to look for in Division 25 Integrated Automation

BAS specs typically name a platform with specific controller families (e.g., "Johnson Controls Metasys with CGM/CVM controllers, or approved equal"). Submittals often propose alternative platforms without an approved equal letter. Look for:
- BAS platform substitutions (Metasys, Desigo CC, Niagara/Tridium, EcoStruxure, Tracer, WebCTRL)
- Controller hardware swaps (Delta Controls, Distech Controls, KMC Controls replacing specified manufacturer)
- Sensor and transmitter brand changes that affect calibration or wiring compatibility
- Graphics workstation and server hardware substitutions
- Field-level device substitutions (actuators, damper/valve controllers) from a different ecosystem
- Software platform version substitutions (e.g., older release lacking specified features)
- Third-party integration middleware replacing the specified native solution

## Severity

Default grade: Blocker. Drops to a Note if the submittal attaches an or-equal approval letter from the architect of record.
