Change Order Review

Change Order Review is the engine that checks a proposed change order against the original contract. It gives every line a status of justified, disputed, excessive or missing backup with a contract-section reference, flags change-order tactics such as scope creep and inflated markup, and calculates a recommended CO value.

What does Change Order Review do?

Change Order Review takes the original contract or scope plus a proposed CO and evaluates each CO line item against the contract. Every line gets a status — JUSTIFIED / DISPUTED / EXCESSIVE / MISSING_BACKUP — with a contract-section reference explaining why. The engine also flags classic CO-gaming tactics: scope creep, inflated markup, vague line-items, duplicate charges.

Output includes a recommended CO value (the JUSTIFIED lines, plus the supported price of any EXCESSIVE line), the savings the review found (lines already in the original scope, and the part of an over-priced line above its supported price), and a separate Not decided amount for lines it was unsure about or that have no backup. The page adds up: requested − recommended − not decided = savings.

When should I use Change Order Review?

Use Change Order Review when a change order request lands and you need to decide how to respond, when you are negotiating a CO that feels bloated, or when you are auditing approved COs across a project for patterns.

What do I upload to Change Order Review?

Upload the original contract, PO or scope of work as the reference, plus the proposed change order document.

How do I run Change Order Review?

To run Change Order Review, open it, upload the contract and the change order, run the analysis, read the verdict card, review each line and check the manipulation flags.

  1. Open the engine

    Sidebar → Engines → Change Order Review.

  2. Upload contract + CO

    Both required.

  3. Run

    45–90 seconds.

  4. Read the verdict card

    CO title + amount + recommended amount + verdict (JUSTIFIED / PARTIALLY_JUSTIFIED / DISPUTED / EXCESSIVE).

  5. Review each line

    Filter by status. Click a line to see contract-section reference and note.

  6. Check manipulation flags

    If present, the engine has detected CO-gaming patterns. Read carefully before responding.

How do I read the Change Order Review results?

The result opens with a verdict card and the change order as a percentage of the contract, followed by a line-item table, any manipulation flags and an AI summary.

Verdict card

CO title, CO number, requested amount, recommended amount, not decided, savings, verdict. A sentence under the figures writes the sum out, and every line the review did not decide says so.

CO percentage of contract

This CO / original contract value — helpful context for whether a CO is large or small in proportion.

Line-item table

Every CO line item, status, in-original-scope flag (YES / no), contract reference, note.

Manipulation flags

Red-bordered section listing any detected CO-gaming tactics (duplicate billing, vague line items, excessive markup, already-in-scope).

AI summary

2–3 sentence executive summary.

Every control, explained

Run analysis

One run.

Filter by status

Narrow to DISPUTED, EXCESSIVE, MISSING_BACKUP, or JUSTIFIED.

Troubleshooting

Contract reference cited is wrong

Engine cites the closest matching section; contracts with unusual numbering systems can throw it off. Use chat to correct.

MISSING_BACKUP flag on lines that did have backup

Upload the backup documentation (T&M sheets, subcontractor quotes) as a third document.

Sample CO result seems too harsh

The Bridgeport sample is designed to show manipulation flags firing — the engine is intentionally showing its worst-case output, not a typical result.
