Know what you're pricing before you commit.
MERT AI reads your tender pack, flags what's missing or contradictory, and drafts the questions to send back to the client. Your estimator stays in charge. MERT does the first read.
Built from nearly 20 years of construction commercial work, on both sides of the contract. We show it on made-up and public tender packs.The gaps show up before you've priced a thing.
This is the first screen after a pack goes in. No return date, an open client question and three specification sections to check, all picked up and laid out as things to do.
- Days to return: not given. MERT says so rather than guessing.
- 14 of 14 documents read. Nothing silently skipped.
- One client question, ready to go in a single email.
What MERT drafts for you to send.
One email, one table, ready for your review. Made-up tender. You edit it, you send it, the client replies in the last column.
Thank you for the enquiry. Before we submit, could you confirm the following?
| No. | Query | Where we looked | Comments |
|---|---|---|---|
| 1 | No return date is stated in the pack. Please confirm the date and time for return. | Enquiry email; tender instructions | |
| 2 | Please confirm the end client / employer for the scheme. | Specification, p.2 | |
| 3 | Please confirm whether rainscreen cladding, cavity barriers and fire stopping are within the façade package. | Employer's Requirements; drawings |
Illustration on made-up data. MERT drafts. You decide what to send.
The expensive tenders are the ones you didn't read properly.
A tender pack is two hundred files, three addenda and a dozen conflicting dates. Your estimator has an hour. Something gets missed.
Two return dates. One pack.
The invitation says Friday, the addendum says Wednesday. Nobody notices until it's too late.
Scope on the drawings, not in the spec
The item you didn't price is the one you'll be asked to build.
The answer you got on the phone
Agreed verbally, never confirmed in writing, gone at final account.
A tender you should never have priced
Hours spent on a job that was never going to be right for you.
The return-date check is live today. Scope on drawings but not in the spec, and tender triage, are what we're building. See the roadmap.
MERT drafts. You decide.
Four steps, and a person signs off every one that matters.
Drop in the pack
Upload the folder. MERT sorts it and accounts for every document, so you know nothing was skipped.
MERT reads it
Return date, client, site, your trade's sections of the specification. Another trade's submission is set aside so it never shapes your scope.
Gaps become questions
Missing information and conflicting documents are flagged, and the client questions are drafted in one email, in a table.
Over to you
You review, edit and send. Replies are matched to each question; phone answers stay marked "not yet confirmed in writing".
Gaps shown, not tidied away.
- Return date, client, site and your trade's sections are picked out of the pack for you to confirm.
- Gaps are shown, not tidied away. A pack with no return date says so.
- You see how many of the pack's documents have been read.
| What MERT found | Source |
|---|---|
| No return date stated in the pack | Enquiry email |
| End client to be confirmed | Specification, p.2 |
| Draft question ready for review | Awaiting your approval |
Built differently, on purpose.
Built for subcontractors, from the subcontractor's side of the table. And we're open about what's live and what isn't.
On your side of the table
Your risk, your return date, your trade's scope, and the questions you need answered before you commit.
Evidence, not opinion
MERT works from the documents in the pack. When documents disagree, it says so instead of picking one.
Drafts, never decides
MERT drafts the questions. A commercial professional reviews and sends. Nothing leaves without you.
Your trade first
MERT finds your trade's sections in the specification and sets another trade's submission aside, so it never shapes your scope.
Written from the commercial side
The checks come from nearly 20 years of construction commercial work, not a generic template.
Honest about its limits
We tell you what's live and what we're building. No promises we can't evidence.
| Question to ask any tender tool | MERT AI |
|---|---|
| Whose side is it built for? | The firm pricing the work. |
| Does it pick one answer when documents disagree? | No. It flags "Documents disagree" and raises the client question. |
| Does it send things on my behalf? | No. It drafts. You review and send. |
| Does it account for every document? | Yes. It sorts the whole pack and accounts for every document. |
| Does it treat a phone answer as agreed? | No. Marked "not yet confirmed in writing" until it is. |
Straight about where we are.
The tender pack is built and working. The rest is on the roadmap and labelled as such.
| Capability | What it does for you | Status |
|---|---|---|
| Tender pack reading | Sorts the pack and accounts for every document. | Live |
| Return date and conflicts | Finds the return date; flags when documents disagree and raises the client question. | Live |
| Missing information | Flags missing client, site or dates and drafts the questions in one email. | Live |
| Answer tracking | Matches each client reply to its question; phone answers marked unconfirmed. | Live |
| Your trade's scope | Finds your trade's sections in the specification and sets other trades aside. | Live |
| Scope on drawings but not in the spec | Compares both and flags the gap. | What we're building |
| Contract review | Your red lines, the amendments read, a schedule of comments to send back. | What we're building |
| Rate book | Your own rates and build-ups, held separately per company. | What we're building |
| Tender triage from a link | A first view of a tender before you download the pack. | Coming next |
One estimator. Too many tenders.
Subcontractors with one estimator, or two, who are constantly overloaded. And smaller firms where the MD does the pricing, the surveying and the contract reviews. MERT is extra capacity for the first read. The estimator stays in charge.
- Built for groundworks, brickwork, facades, roofing, M&E and specialist trades. We show it on made-up and public tender packs.
- Tell us how you'd like to use it. We're testing both a self-run tool and a done-for-you service.
- We're building MERT AI so each company's tenders are kept separate and never pooled
- Every output is reviewed by your commercial professional before anything is sent
Clear limits, so you can trust the rest.
- It doesn't send anything for you. You review and send.
- It doesn't replace your estimator's judgement or give legal advice.
- It doesn't yet compare drawings with the specification, or measure quantities.
- It doesn't treat a phone answer as agreed until it's confirmed in writing.
Built from the commercial side.
Stephen Lynch started at Laing O'Rourke and Willmott Dixon, ran his own projects, and has been commercial lead on £50m and £100m residential schemes. Nearly 20 years of construction commercial work, on both sides of the contract. MERT AI puts that experience on the subcontractor's side of the table.
MERT drafts. You decide.
You keep control of every question, every confirmation and every decision. We make sure you've seen everything before you do.
Request a walkthroughStraight answers.
Does MERT replace my estimator?
No. It's extra capacity for the first read of a pack. Your estimator reviews everything and makes every decision.
Can I trust what the AI says?
You review everything before it's used; that's why nothing is sent without you. Where MERT reads with AI, that's shown on made-up and public packs today, and we'll walk you through how its findings are checked.
What happens to my documents?
We're building MERT AI so each company's tenders are kept separate and never pooled. No client data goes onto our hosted system until an independent security test has passed, and before any trial you'll get our data terms in writing. See Security and data and our privacy notice.
Is this ready now?
The tender pack is working and shown on made-up and public packs. Contract review and the rate book are what we're building. We'll show you exactly where each stands.
Is it legal or contract advice?
No. MERT supports commercial review. It is not legal advice.
See it on a tender pack.
In the walkthrough we read a pack live, in front of you, on made-up data. Then a straight conversation about whether it would help your team. No obligation.
