AGMM / Industries / Construction
AI for construction companies: where the margin actually goes.
Almost everything sold to contractors under the word AI answers the enquiry faster. None of it touches the step where the money is decided: the measure and the price. AGMM is an AI consultancy whose founders write the code, and the one job it publishes in full is a construction job.

The specific claim this page makes
What has AGMM actually built for a contractor?
Before anything else, here is one job we priced, in full. A first-floor build-over in Heaton Moor, Stockport, issued by Cheadle Construction on 14 July 2026, reference JAY-AA-20260713. 63 measured lines. £98,214.72 including VAT. Open it and read every line.
It was produced by QSQuoter, a quoting and estimating system AGMM built, and published in two versions on purpose: a client copy that reads calmly, and a tradesman copy with the working shown. Preliminaries and site set-up £17,374. Bathrooms and en-suites £15,962. Internal walls and finishes £11,245. Mechanical and electrical £6,290, plus six more sections. Every line traces back to a dimension you can check. A bill of quantities is measured, not estimated.
The gap in this market
Why is everyone selling faster lead chasing when the margin is in the pricing?
Because lead chasing is easy to sell and easy to demonstrate. A sixty-second callback is a clean before and after, and the software is nearly a commodity. It is also genuinely useful, and further down we say when we would build it.
But a contractor rarely loses money because an enquiry was answered in an hour instead of ten minutes. A contractor loses money because a quantity was measured optimistically, a rate was last reviewed two price rises ago, preliminaries were carried at a percentage nobody defends, or a variation was agreed on site and never priced. All of that sits between enquiry and invoice, in the part of the process almost no AI supplier goes near, because it requires knowing what a bill of quantities is.
AGMM starts there, because pricing carries the largest number and because the one artefact we publish is proof we build to that standard.
Measurement and rates
Can software actually price a job?
It can hold the measure, apply your rates consistently and produce a bill a quantity surveyor can audit line by line. That is narrower than the usual claim and more useful. Arithmetic was never the hard part of estimating. The hard parts are that the measure has to be right, the rates have to be yours and current, and the assumptions have to be visible to whoever checks the job.
What a system genuinely takes off a person: re-typing quantities, applying the same rate the same way every time, carrying preliminaries and overhead recovery by a rule rather than a feeling, keeping a copy of every quote sent, and producing both documents.
What it should not take: the judgement. Whether this ground is worse than it looks, whether this programme is achievable in March. Those stay with your estimator, and a good system makes them explicit inputs rather than something buried in a rate.
The build side sits on quoting and estimating software.
The processes, in order
Which processes does a £1m to £50m contractor recognise?
These six carry the time and the margin in nearly every contracting business we talk to.
- 01
Enquiry to site visit
Enquiries arrive by phone, by email, through a form and through somebody the estimator knows. Nobody can say at a glance which have been visited, which wait on a price and which died three weeks ago.
- 02
Measurement and takeoff
Quantities come off drawings and a site visit into a spreadsheet one person understands. The measure is the asset, and it usually lives on one laptop in a file named after the client.
- 03
The bill of quantities, priced
Rates from a rate book, a supplier, memory and the last similar job. This is where the margin is set, and it gets the least software help of any step.
- 04
Variations and what was agreed
A change is agreed on site, sometimes verbally. Six weeks later the difference between a profitable job and an argument is whether anyone wrote it down, priced it and got it acknowledged.
- 05
Subcontractor packages and payment applications
Packages sent, prices returned, work instructed, applications assessed, retention tracked. It is a document workflow, and in most firms it is an inbox.
- 06
Site diaries, records and handover
Daily records, photographs, delivery notes, inspections and the operation and maintenance pack. A handover assembled at the end from six places costs more than one assembled as you go.
Sequencing
What should you automate first, and what does the £2,000 audit decide?
Not the most annoying thing. The thing with the largest number attached that you can change without stopping the business. In most firms that order comes out as: the record of what was agreed, then the priced bill, then the enquiry pipeline.
The record first, because it is cheap and stops losses immediately. Variations captured on site, priced, acknowledged and attached to the job is a small piece of software that settles arguments costing thousands. The priced bill second: largest number, but it needs your rates agreed first. The pipeline third, because winning more work at a rate that does not cover you is not a win.
None of it needs your accounting system replaced. Leaving Sage or Xero in place and connecting to it is almost always the cheaper answer. Which of those is true for your business is what the fourteen-day constraint audit establishes, from your figures rather than a sector benchmark. Site and subcontractor scheduling is built with scheduling software; the document chasing around packages and applications is business process automation.
Records and standards
What does the Building Safety Act expect you to keep?
For higher-risk buildings the Building Safety Act 2022 introduced a duty to keep and hand on a reliable information trail, the golden thread: what was designed, what was built, what changed and who decided. Whether it applies to your work is a question for your own advisers. This page is not compliance advice.
The software point is narrower and worth making. A business that assembles its records at handover, out of six inboxes and a camera roll, does expensive work twice and produces a weaker record. One whose site diaries, instructions, variations and inspections are captured as they happen already holds most of the trail, and handover becomes an export. That holds whether the regime applies or whether it is your client, your insurer or a purchaser asking.
A system that records the measure and the change as they occur can produce the document later. One that does not, cannot. The same holds for RICS new rules of measurement where a bill of quantities is in play.
The commercial terms
What does it cost? The audit is £2,000, then a scoped build.
One published price and one invoice: £2,000 for a fourteen-day business-wide constraint audit, built around three sixty-minute sessions with the engineers who would scope any build. You keep four documents whatever you decide: a constraint map, an AI opportunity map, an economic case per option, and a ranked order for spending.
A build is proposed afterwards in its own document, priced to the work. We publish no band for construction, because the number is set by how many pricing rules the system must hold and the state of the rates going into it. The audit fee is not credited against the build, so the recommendation is not paid for by the thing it recommends.
The full ladder is on what it costs. What other UK firms publish, sourced and dated, is on the AI consultancy cost comparison.
Boundaries
What this does not include
- Hardware, licences and subscriptions. Those stay in your name and AGMM takes no margin.
- A rate book. If your rates are not written down, agreeing them is your work, and usually the real project.
- A guarantee of margin, hours saved or quotes won. AGMM cannot evidence one, so it does not sell one.
- Estimating accreditation, quantity surveying practice or any regulated opinion, including compliance sign-off under the Building Safety Act. We build information trails; the duty stays yours.
- The build itself. The £2,000 buys the diagnostic, and the fee is not deducted from a build.
Fit, stated plainly
Who this is not for
- Sole traders and two-van firms. A business under roughly £1m of turnover rarely has a constraint big enough to repay a £2,000 audit. Off-the-shelf estimating software is the better answer, and we will say so.
- Anyone who wants a lead-chasing chatbot and nothing else. Other firms sell that more cheaply.
- A business whose rates exist only in one person’s head and who does not want that to change. Software cannot write down a judgement nobody will articulate.
- Anyone who needs work started next week, or who wants a free strategy document. The audit is fourteen days by design and the diagnostic is paid, deliberately.
If that is you, the honest route is off-the-shelf estimating software or a cheaper tool, and the fit call will say so in thirty minutes rather than after an invoice.
The limits of our evidence
What we cannot show you yet
The Stockport job proves one thing: AGMM can build software that prices a construction job to a standard an expert can audit. It does not prove hours saved, a margin improvement, a win rate or a return on investment, and we will not imply that it does.
AGMM is a young company, incorporated in April 2025, and most of its work sits inside client systems we cannot publish. There are no construction case studies here because there are none we can link and check, and no percentage savings, because we have not measured them across enough jobs. Until that changes, one number you can open beats five you cannot.
Questions before a call
Frequently asked questions
How are UK construction companies using AI in 2026?
Most of what is sold to contractors under the word AI is front-office: chasing enquiries, following up quotes, collecting reviews, answering calls. Those are real problems and the tools work. Almost nobody addresses the money process: measurement, rates and the priced bill. That is where a contractor makes or loses a job, and where AGMM starts.
Can software actually price a job?
It can produce a measured, priced bill a quantity surveyor can audit line by line, which is a different claim from guessing a total. The job AGMM publishes is exactly that: 63 measured lines, priced against a calibrated 2026 UK rate book, £98,214.72 including VAT. A bill of quantities is measured, not estimated, and a system that blurs that is selling a guess with a decimal point on it.
Is my business too small for this?
Probably, if you turn over under about £1m. The £2,000 audit and a scoped build make sense when a process costs enough each month to repay them, which in practice means roughly £1m to £50m of turnover and more than one person touching a quote. Below that, buy off-the-shelf estimating software, and we would rather say so on a free call than take the fee.
What does it cost?
The diagnostic is £2,000, fixed, over fourteen days, and it is the only price AGMM publishes. A build is priced afterwards in its own document, because the cost of a quoting system is set by how many rules it must hold and the state of the data, not by a band on a web page. The audit fee is not credited against the build. The full ladder is on the what it costs page.
Can it use our own rates and our own margin?
That is the point. A rate book that is not yours prices somebody else’s business. The work is getting your rates, preliminaries, overhead recovery and margin written down once, in a form the system applies consistently, so a quote reflects a decision rather than the mood of whoever priced it. Where those rules are not written down yet, writing them down is the part of the build that pays.
What is QSQuoter, and is it right for us?
QSQuoter is a quoting and estimating product AGMM built, and the system that produced the published job. It is not automatically right for your business. The audit decides whether you need a product like that, a smaller change to what you run, or nothing at all.
