Takeoff revision control for changing construction drawings
A quantity is only useful when the estimator can identify the plan set, scale, and scope behind it. Rivet keeps drawings, measurements, costs, and project revisions together so changed work can be reviewed before it becomes a bid or order.

THE WORKFLOW
A clear path from source drawing to reviewed work.
Each step keeps the project understandable to the estimator who created it and the person who reviews it next.
01
Record the revision
Record the drawing revision or addendum number, issue date, affected sheets, and the person responsible for review.
02
Preserve the baseline
Keep the prior estimate state and a portable backup before replacing drawings or updating affected quantities.
03
Review every change
Read the addendum notes, inspect changed sheets, and identify the quantities, labour, material, and assumptions affected.
04
Approve the revision
Check the revised estimate, record unresolved items, and share the approved project revision with the team.
STALE DRAWING RISK
Superseded plans can change far more than a quantity
A drawing revision can affect material, labour, subcontractor quotes, equipment, procurement timing, exclusions, and the basis for a change order. Measuring from the wrong issue puts all of those decisions at risk.
Use a drawing register and a dated estimate baseline. A filename, revision cloud, or email timestamp is not enough on its own to prove the source was current.
Confirm the drawing index and addendum notes
Link affected scope to the measured quantity
Retain the old baseline before changing the estimate
Keep source drawings and estimate details together
Rivet imports PDF plan sets, stores the project locally, and keeps measured takeoff and estimate work in the same workspace. Optional encrypted Cloud revisions can carry that workspace to another permitted device.
The revision check protects against silently overwriting newer Cloud work. You still need to compare the drawings, identify changes, and decide which quantities to remeasure.
For each addendum, record what changed, which scope items were reviewed, what remains unclear, and which assumption was used. Then compare the revised estimate with the preserved baseline before issuing it.
This review is especially important when a project moves between office and field devices. The receiving person should know both the approved drawing issue and who owns the next change.
It is the process of identifying the drawing issue used for a takeoff, preserving the prior estimate state, updating affected quantities, and documenting why the result changed.
Does Rivet automatically detect every drawing change?
No. Review the complete issued set and addendum to identify changes, then update the affected quantities and costs.
Should I overwrite the old takeoff?
Preserve a dated baseline and a portable backup first. That gives reviewers evidence for the quantity and pricing change.
How does revision control work across devices?
Rivet Cloud uses encrypted workspace revisions and will not silently upload older work over a newer Cloud revision. Teams should still assign ownership and confirm the drawing issue before a handoff.
No card is needed for the downloaded-app trial. Use a representative PDF plan, verify the scale, measure the scope, review the estimate, and test the handoff that matters to your team.
