Section 97 of 103
96. Upgrade, Retrofit and Reconfiguration
Stable section ID: S05-CON-015-SECTION-97 · 15 content blocks
An Upgrade is a controlled change intended to improve capability, performance, safety, efficiency, compatibility, or lifecycle value.
A Retrofit is the addition or modification of an existing Asset after its original manufacture, installation, or commissioning to satisfy new or changed requirements.
A Reconfiguration is a controlled change in the selection, arrangement, parameters, relationships, or operating state of existing entities.
An Upgrade may involve Retrofit and Reconfiguration, but the terms are not interchangeable. Reconfiguration may occur without physical modification, and Retrofit may restore compliance without increasing overall capability.
Changes shall consider:
structural and functional effects;
Interface and version compatibility;
fire and life-safety conditions;
utilities and environmental systems;
cybersecurity and software dependencies;
inspection and maintenance access;
Building BIOS and Digital Twin updates;
- backward compatibility and future replacement.
- An upgraded subsystem shall not make the entire Building “upgraded” unless the scope is declared.
All changes shall preserve the previous configuration, change authority, evidence, and resulting authoritative baseline.
