Documenting the source of a quantity

A workflow guide for preparing and reviewing a BOQ. It describes professional checks and does not promise automatic recognition, compatibility or a connection that has not been verified for the project.

AiN demo: model alongside a quantity table

Check the source

Explain how each quantity was produced: model data, drawing measurement, calculation or manual completion. Record the file, revision and transformation. A generic source label is insufficient if reviewers cannot return to the material that was checked.

Incorporate the data

Distinguish a checked measurement from imported data or an unapproved suggestion. The distinction matters even if the numbers agree. It identifies the further review required before pricing or delivery.

Review before issue

A model line stays associated with its originating elements, while a supplementary source is documented separately. Do not erase this distinction during updates merely to make the table look uniform.

Review checklist

Identify the source file and revision.
Record the unit and measurement rule, and check scope boundaries.
Distinguish model data, manual completion and AI suggestions.
Record missing data or exceptions before using a quantity for pricing.

AiN uses AI and can make mistakes. These guides were prepared with AI assistance and have not been reviewed by Yaakov Avital; professional review is required before project use.
