Building BIOS Architecture

Model Reconciliation resolves differences among the building’s digital representations and verified physical condition.

The reconciliation process shall compare:

As-Designed model;

approved Building Manifest;

BIOS registries;

Digital Twin;

Building Definition Language model;

manufacturer records;

commissioning records;

observed physical state;

maintenance and inspection findings.

A discrepancy may involve:

identity;

component type;

version;

location;

orientation;

Interface connection;

capability;

state;

dependency;

geometry;

lifecycle status.

The reconciliation process shall:

identify the discrepancy;

preserve all source records;

classify each source by authority and evidence;

determine whether the physical state can be verified;

identify the correct authoritative condition;

evaluate engineering and operational impact;

correct erroneous models through traceable changes;

initiate configuration change where the physical building has legitimately changed;

record unresolved uncertainty.

No source shall automatically dominate every discrepancy. The approved design may govern intent, while verified inspection governs actual physical presence. Certification records may govern rated capacity, while current inspection governs degraded condition.

AI may assist in matching records, detecting geometric differences, or proposing reconciliation, but shall not silently alter authoritative models.

A reconciled model shall identify the date, evidence, responsible authority, and effective configuration version.
