Change orders priced from what actually changed.
A change order is only as strong as its backup: what changed on which sheet, the quantity difference and the price. RenderDraw links every proposed quantity to its source sheet, so change pricing starts from a traceable takeoff.

- Revision deltas
- Traceable backup
- Faster approvals

Five steps to a change order that gets approved.
Identify
Which document changed: ASI, RFI response, bulletin, revised sheet.
Quantify
Measure only the delta, with sheet references.
Price
Material, labor, equipment, markup per contract.
Document
Narrative, backup, schedule impact.
Submit and track
Log status until executed.
The quantities a trade estimator actually needs
These are the items RenderDraw proposes from the drawings, each linked to the sheet it came from, for your estimator to accept, correct or reject.
| Item | What is measured or counted | Where it comes from |
|---|---|---|
| Counts | Symbols, devices, fixtures and doors against the legend | Plans, legends, schedules |
| Lengths | Walls, runs, edges and linear items | Plans, details |
| Areas | Rooms, finishes, roofs, paving | Plans, finish schedules |
| Volumes | Concrete, earthwork, fill | Sections, schedules |
| Scope items | Requirements, exclusions and alternates | Specs, general notes, addenda |
From plan set to reviewed quantities.
AI-powered, human-approved. Each stage records what ran, what changed and who approved it.
Start with your bid package
Drawings, specs and addenda together: the plan set, legends and schedules, the spec sections for your scope and any addenda.
AI proposes quantities
Counts, lengths and areas come back with the source sheet and location attached to every row.
Estimator review
Low-confidence items surface first. Your estimator accepts, corrects or rejects each one.
Map to your assemblies
Approved quantities map to your items, assemblies and estimating assumptions.
Price reviewed rows
Labor units, material pricing and supplier quotes apply only to rows that passed review.
Hand off with evidence
Approved quantities move on to pricing and visual CPQ with the evidence trail still attached.

The AI drafts. Your estimator decides.
Speed is easy to promise. Defensible numbers are the job, so RenderDraw keeps the estimator in control of every quantity that gets priced.
- Source on every row. Each quantity keeps its source sheet, location and reviewer decision.
- Lowest confidence first. The review queue shows the drawing tile with the detection highlighted and the extracted value.
- Uncertain items flagged, not hidden. Anything the AI can't confirm goes to the estimator rather than being guessed.
- Nothing priced before approval. Rows move on to pricing only after they are accepted.

Questions estimators ask
What is change order software?
Software to price, document and track construction change orders.
What should a change order include?
Description, reason, cost breakdown, schedule impact, backup and signatures.
How do I price a change order?
Quantify the delta from revised documents and price per contract terms.
How does RenderDraw help?
Traceable quantities: every proposed quantity keeps its source sheet, so the rows a change touches are easy to find and recheck.
See what the AI reads on your own drawings.
Send one representative trade plan set. RenderDraw reviews it and follows up with what the AI extracted and what it flagged for review. Your files remain private while the request is assessed, and there is no obligation.
- Upload the plan set, legends and schedules, the spec sections for your scope and any addenda.
- RenderDraw reviews the set and the scope you want tested.
- We follow up with extracted quantities, flagged items and next steps.
