Power and circuit changes
A revised panel schedule or feeder note may affect the circuit, conductor or equipment allowance in your bid.
Review in context
Compare the affected plan, schedule and specification before revising the estimate.
For US commercial electrical contractors
Find the revisions that may change your electrical bid.
A revised lighting plan, panel schedule or equipment requirement can change the assumptions behind your takeoff. Keep the original bid set and each addendum connected to the electrical scope you are pricing.
Your review. Your project data.
Keep your team in control.
RevisionSignal supports your judgment. It may miss changes, and a finding still needs your review.
Keep professional review in place.
Early Access starts in Shadow Review. Verify findings against the source and continue your normal review process.
Start with a conversation.
Describe your workflow in the access request. Leave out confidential drawings, specifications, and bid details.
Agree on data handling first.
Before sharing live files, confirm who can access them, which providers process them, and the retention and deletion terms.

Addendum 2 · March 27, 2026
Manually reviewed example
Before · Original bid setE2.1
No starter symbol or callout at the selected location near L8.
Before PDF · page 8 (opens in a new tab)After · Addendum 2E2.1
The starter symbol and callout appear inside the revision cloud.
After PDF · page 19 (opens in a new tab)Red outline: selected change. Dashed outline: corresponding area before the change. Black revision cloud: part of the source drawing.
What changed
A spray-pump starter symbol and its location are added to E2.1, beside panel L8.
Why it may matter
The location and circuit routing need coordination. A starter was already required by the original mechanical schedule.
What to review
Check the starter quote, routing, E0.0 note 2 and the added motor-controller specification.
One manually reviewed change. Not an automated product result or a complete list of addendum changes.

Electrical review scenarios
What a revision can change.
These scenarios describe the review workflow we are developing. They are not automated findings or a statement of currently supported detection coverage.
Lighting and device revisions
Added, moved or removed fixtures and receptacles may change counts, locations and installation assumptions.
Review in context
Check the device tag and legend as well as the changed region. A moved symbol is not automatically an added device.
Equipment connections
A mechanical or plumbing equipment revision may introduce a different power connection or control interface.
Review in context
Review the equipment schedule and responsibility notes to establish what belongs in your scope.
Start with the right documents.
Start with the electrical plans, legends, panel and lighting schedules, specifications and addenda. Include mechanical equipment schedules and other documents referenced by the electrical scope; a new connection requirement may appear outside the E-series sheets.
Your team stays in control. Verify source documents and continue your normal bid review.
Before you join
Electrical review, explained.
Does this replace electrical takeoff software?
No. RevisionSignal is being developed to support revision review. Your team still verifies quantities, selects assemblies and prices the bid in its estimating workflow.
Should we review only the electrical sheets?
Use the complete set of documents relevant to your contract. Equipment schedules, addenda and specifications outside the electrical sheets can reference electrical work.
What does Early Access intake mean?
We are accepting conversations about electrical review workflows. An access request does not activate a production service. Availability, supported documents and Shadow Review terms are agreed before a pilot.
Electrical · Early Access intake
Let’s talk about your next electrical bid.
Electrical is accepting Early Access requests. Tell us about your revision review so we can discuss availability and pilot fit.
A simple next step
Send a brief request from this page. We’ll review it and discuss availability, coverage, and terms before a pilot begins.
Early Access may miss changes. Keep your normal estimating and document review in place.
