Live margin on every project. While there's still time to act on it.

From groundworks firms to £100M main contractors, the story is the same. The work is good. The systems leak. Variations go unclaimed, retentions sit unchased, and the CVR arrives after the damage is done.

A bespoke AI platform fuses your commercial data, your site records, your compliance and your pipeline into one brain you own outright, on private UK infrastructure with snapshot replication to a separate UK data centre, with a website that wins tenders while you sleep.

Where Construction Margin Goes

The leaks every contractor knows about. And nobody has time to fix.

01

Margin dies quietly, one unclaimed variation at a time.

"How much legitimate variation work did you give away last year?"

The site team does the extra work because the job has to move. The paperwork lags. The QS finds out at final account, the notification window has closed, and the client politely declines. Your brain logs the variation the moment it happens, photographs the evidence, prices it from your rates and chases the signature before the contract clock runs out.

02

Retentions are your money. They behave like someone else's.

"What is your total retention pot and which releases are overdue?"

Most contractors cannot state their retention position without a half-day spreadsheet exercise. Defects periods expire and nobody notices, so cash that belongs to you sits in someone else's bank. The platform keeps a live retention ledger across every contract, flags the day a release falls due and drafts the chase letter for you.

03

You find out a job lost money at final account. Months too late.

"What is the live margin on every job, today?"

Cost lands from timesheets, supplier invoices, plant hire and materials, but it only meets the valuation once a month if you are lucky. By the time the CVR says trouble, the trouble is historic. Live cost capture against budget means the platform tells you a job is drifting while there is still time to do something about it.

04

Compliance lives in a filing cabinet until the HSE asks for it.

"If an inspector walked onto site today, how fast could you produce everything?"

Plant certs, RAMS, training cards, inspection records: scattered across email, site cabins and someone's laptop. One lapsed certificate can stop a site. Everything lives in one place with expiry tracking, so renewals happen before they bite and an audit is a ten-minute export, not a ten-day panic.

The Alternative

Seven logins. Seven invoices. None of them talk to each other. Your brain replaces the lot, and you own it.

The Platform

Modules built around how a contracting business actually runs.

COMMERCIAL & CVR

Live cost value reconciliation on every project.

Costs captured as they land, valued against budget daily. Margin by project, by phase, by package. The monthly CVR becomes a confirmation of what you already knew, not a monthly surprise.

VARIATIONS

Captured on site. Priced. Chased to signature.

Site teams log a variation from a phone in under a minute, with photos. Cortex prices it from your schedule of rates, generates the notice and tracks it against the contractual notification window so nothing gets time-barred.

RETENTIONS

A ledger that fights for your money.

Every retention tracked by contract, with practical completion and defects dates. The platform flags releases as they fall due and drafts the application. Money that used to leak now comes home.

SUBCONTRACTORS

Performance scored. Paperwork automated.

Insurance, accreditations and payment terms in one place. Programme performance and defect rates scored from real data, so the next tender goes to the sub who delivers, not the one who answered the phone first.

H&S & COMPLIANCE

Audit-ready every day of the year.

RAMS, toolbox talks, plant certification and training records connected to people and sites. Expiry alerts fire weeks ahead. When the auditor calls, you export the pack instead of building it.

TENDERS & PIPELINE

Bid the right work. Learn from every loss.

Every tender tracked with outcome, margin and client history. Cortex compares new enquiries against jobs you have actually delivered, so you price from evidence and stop chasing work that never makes money.

Meet Cortex

One assistant. Total recall.

Cortex has read every contract, every valuation, every timesheet and every site diary. Ask it which job is drifting, which variation is about to time-bar, or which subcontractor to trust with the next package.

"It answers like a commercial director who has been on every site, read every contract and never once forgot to chase a retention."

The Virtual Board Member

Your directors submit four updates.
Cortex submits the fifth.

Every director takes two minutes on the last Friday of the month. The brain collates their updates, cross-references them against everything it knows about the business, and produces the board pack. Then it adds its own report: an independent analysis no director wrote, with no political considerations, that flags what the board needs to act on before the meeting starts.

VIRTUAL BOARD MEMBER REPORT

The following analysis was prepared by Cortex from the director updates above, combined with live platform data. It is independent of any director's submission and has been prepared without prior sight of the agenda.

RED
Margin Risk

Live project margins are tracking 2.2 points below target. The primary driver is variation under-claiming. At current run rate, £31,200 in legitimate variations will lapse this quarter. This is a recoverable position but requires commercial action this week, not next month.

AMBER
Cash Flow Outlook

Three overdue invoices represent 18% of the current cash position. Two of the three have been chased once. Based on historical payment behaviour, Hargreaves Developments typically settles within 7 days of a director-level call. Recommend escalation before month end.

GREEN
Pipeline Quality

The three tenders submitted this month are well-matched to your delivery capacity and margin profile. Win probability based on historical conversion at this stage is approximately 40%. One opportunity is with a client where you have a strong relationship history and no lost tenders.

RED
Risk to Watch

Two plant certification renewals lapsing end of month. If these are not renewed before the Birmingham site visit on 24th, you risk a prohibition notice. This is flagged as a high-priority operational action.

Independent

Cortex has no politics, no relationships to protect and no agenda. It tells the board what the data says, not what anyone wanted it to say.

Complete

It has read every director's update and cross-referenced it against live platform data before it writes a word. No human could do that in 40 seconds.

Cited

Every claim references its source. The board can interrogate any finding and trace it back to the underlying data, transaction or record.

Governed

Runs under the Sheriff: cites sources, flags uncertainty, never invents figures and always distinguishes between what the data shows and what it recommends.
