A project is more than a collection of documents.
MUR treats project truth as the controlled state of engineering objects, properties, relationships, topology, spatial information, requirements, engineering decisions and validated derived results. Project documents are controlled views of that state.
A document can be the latest revision and still be technically stale.
Revision status and engineering consistency are different dimensions. When an approved project fact changes, every dependent result must be identified and its current status reconsidered.
From evidence to validated engineering results.
P&ID → Datasheet / CBS → Layout & Routing → Loop / JB / Terminal
P&ID defines functional intent. The project datasheet defines equipment requirements. CBS establishes the basic connectivity chain. Layout and cable routing add physical placement and route. Loop, JB and terminal documents complete detailed wiring.
Calculations, Ex/intrinsic-safety assessments and the technical description remain linked to the same approved project state.
Connectivity develops in controlled stages.
A project does not need every detail at the beginning. Unknown values are legitimate until the relevant maturity gate requires them.
PROPOSED ≠ PROJECT TRUTH.
An AI suggestion, OCR extraction or value found in vendor documentation becomes part of project truth only after the required engineering verification and approval.
Change analysis becomes executable engineering logic.
The Project Truth Matrix defines ownership, source, approval, validation, document usage and expected impact for relevant project facts and relationships.
