What changed

Start with the agreed scope.

A revised drawing is only half the story. Put it beside the original so the team can see the extra work and the basis for its price.

Keep value separate from approval

The proposed amount belongs in the register while the decision is outstanding. It becomes approved work only after the team records that decision.

Keep time effects in view

Flag programme questions alongside the cost, so the project team can assess the change as a whole.

The app

A proposal with the working attached.

Keep the instruction, original scope and proposed price together. Review the commercial and programme effects before the change moves forward.

Questions

What people ask about change order review.

Can reviewers see the documents behind a change?

Yes. Source citations let your team open the passage behind an extracted value. The example keeps original and revised quantities beside their source documents.

Who decides whether to submit a proposal?

Your team reviews the proposed change and decides what to send. The app brings together the working and source evidence for that review.

Do we have to build the app ourselves?

No. We can map your process, build the workflows and the app, and hand your team something ready to use. Your team can change it later or ask us to.

Can we change the fields and review steps?

Yes. Describe what you need to the Assistant. It can change workflows and apps, with every change shown for your approval.

Is our project data used to train models?

No. Your documents and results are never used to train a model, and a data processing addendum backs that.

Which document-heavy job would you hand over first?

Bring one process you want to improve and the information behind it. We build the first version with you in the session, so the first thing you see is your own work, running.
