03

An NRM2 bill built from the take-off against a rate library, as a draft for QS approval.

Programme building

A tender programme drafted from the pack, then edited by a person.

05

Quote levelling

Subcontract enquiries out, quotes back and levelled line by line against the bill.

Your questions

Humans decide

AI does the admin. You make the call.

The platform reads, measures and drafts. Nothing leaves it until a named person on your team has checked it and approved it, and every step sits on the record.

Access by role

Estimators see their packages. Subcontractors see only their own enquiry.

UK or EU residency

Your data held in the region you choose, set per account.

Never used to train AI

Your rates, tenders and margins train nobody's model.

Every AI request logged

By document and user, exportable whenever you ask.

Straight answers

Will you price one of our tenders on the call?

No. The demo shows the platform working on a tender pack we hold. Your own tenders run in the platform once you start.

Do we have to move live projects across?

No. New jobs start in ConstructEther and stay there. Live projects finish where they are.

Who should join the call?

Whoever prices your work, and whoever signs off the software.

Can I trust a number the AI produced?

Every quantity shows its working, and nothing is issued until a named person approves it.

A few questions, then pick a time.
