Run Your Business Like a £50m Contractor.
For £100/Month.
Enterprise-grade cost management, programme scheduling, RAMS, tender analysis, and payment applications — in one platform, from one login, working within a week. Built by a contractor with 30 years experience.
As seen in
You've seen the firms that always seem to have it together.
Their tender submissions are crisp. Their programmes are professional. Their payment applications land on time, every time. They've got a commercial manager tracking margins, a planner updating the programme, a H&S advisor producing site-specific RAMS, and a document controller who makes sure nothing falls through the cracks.
You've got yourself. Doing all of it. Usually after the kids are in bed.
Here's what those firms have that you don't — and it's not more people. It's systems.
What you're about to read is a straightforward explanation of how you can get access to that same back-office infrastructure — for less than a day's labour rate per month.
If you're too big for spreadsheets and too small for enterprise software — this was built for you.
Here's a brief outline of what you'll discover inside:
The real reason your margin erodes. It’s not your pricing. It’s not your subbies. It’s something that only becomes visible when your cost data and your project data are connected in real-time — and right now, they’re not.
Think you need to spend £15k+ on software to run your business properly? We’ll show you how to get 16 integrated modules — CVR, tenders, RAMS, programmes, payments, variations, drawings, specs, comms and more — for £100 per seat per month. Less than a day’s labour rate.
The “Late Night RAMS” problem — and why it doesn’t have to exist. There’s a way to produce site-specific, CDM-compliant risk assessments in the time it takes to boil a kettle. Without a H&S consultant. Without copying and pasting from the last job.
How the top contractors are hitting 40% tender win rates while most are flipping coins at 20%. It’s not because they’re cheaper. It’s a specific thing they do in the first 30 minutes with the tender documents. And it’s now something a system can do for you.
The silent cost of every variation you didn’t write down. Add them up over 12 months and you’ll understand why you’re working harder every year but your bank balance doesn’t move. There’s a way to make sure nothing walks out the door unrecorded.
Late payment applications don’t just delay your money — they start a chain reaction. Your application slips a week, the payment notice comes late, the final date shifts, and suddenly you’re funding the project from your overdraft for an extra month. There’s a system that ensures you apply on time.
What happens to your business when you take a week off. If the answer is “it stops” — you don’t have a business. You have a job you can’t resign from. There’s a way to change that, and it’s got nothing to do with hiring more people.
The exact reason you’re turning down work you should be winning. It’s not capacity. It’s not money. It’s the days of admin attached to every new job that you don’t have — and a system that reduces it to hours.
Let's talk about where you actually are.
Not where you tell clients you are. Not the version you put on your PQQs. Where you actually are, right now, today.
You're the estimator, the planner, the QS, the commercial manager, the H&S advisor, the site manager, and the man who locks up on Friday. You do the work of five people and you get paid for one.
You know you need better systems. You've known for years. Every time a payment application goes in late, every time you price a tender on gut feel, every time you realise a variation was never recorded — you know.
But every time you've gone looking for the answer, you've hit the same wall.
Enterprise software that costs more than your van. Platforms with six-month implementation timescales. American systems that don't understand CIS, can't handle domestic reverse charge VAT, and think JCT is a motorway junction. Tools that do one thing brilliantly and nothing else — so you end up with seven subscriptions and none of them talk to each other.
So the cycle continues. No time to fix the problem. No systems because there's no time. No time because there's no systems.
That's the gap nobody was building for. Until now.
And here's the bit that matters.
You've already tried to fix this. More than once. And it wasn't because the attempts were bad — it was because the tools weren't right.
You set up the shared drive. Two weeks later the lads were back on WhatsApp and the shared drive had three files in it, two of them called “Copy of Copy of Final_v2.”
You spent a weekend building the mother of all spreadsheets. Then someone edited a cell they shouldn't have, and the whole thing started giving you different numbers depending on which tab you looked at.
You're brilliant at what you do — you can hold an entire project in your head, programme, costs, risks, every trade, every deadline. That's actually the problem. It's all in your head. And a business that lives inside one person's head doesn't scale.
Every system you've tried has failed because it needed the one thing you don't have — time to implement it, time to maintain it, time to make it stick.
The tools weren't built for someone who can't stop working long enough to set them up.
That changes now.
Built By A Builder. For Builders.
Steve McKenna
MCIOB · MD, Gemstone Contractors · Founder, Construction AI
My name's Steve. MCIOB, 30 years in the industry. I've run jobs at UBS 5 Broadgate and Westfield London. I'm the Managing Director of Gemstone Contractors, a CIOB Chartered Building Company. I price tenders. I manage programmes. I write RAMS. I chase payments. I sit in CVR meetings and explain why the margin's moved.
I had every problem you've just read about.
So I built the solution.
Construction AI is 16 integrated modules — cost management, tenders, RAMS, programmes, payment applications, variations, drawings, specifications, communications, RFIs, submittals, site diaries, H&S libraries, CPD tracking — all connected, all in one place, all powered by an AI agent who actually understands construction.
I didn't build it to sell software. I built it because I needed it. Every module exists because I hit the problem on a live project. Every workflow is designed around how UK contractors actually work.
And I built it so it works from day one. Not after six months of implementation. Not after three days of training. You sign up, you book an onboarding call, and you're running your first project within the week.
Because I know you haven't got six months. You've barely got six minutes.
You might be thinking…
“I’ve been burned by software before.”
Of course you have. Most construction software was built for firms ten times your size, by companies who’ve never set foot on a building site. Construction AI was built by someone who uses it on live projects every week. Every feature exists because I needed it — not because a product team thought it would look good in a demo.
“I’m not tech-savvy.”
Good. Neither am I. I had zero software development background before I started building this. If I can build it, you can use it. The AI agent does the heavy lifting — you describe what you need in plain English, the kind of English you’d use on site, and it does the work.
“My business is too small for this.”
Your business is exactly who this is for. This isn’t enterprise software with the features stripped out to make a “lite” version. It’s purpose-built for contractors who are too big for spreadsheets and too small to pay for enterprise software. Every screen, every workflow, every default setting is designed for your size of operation.
“£100/month per seat — that’s a lot.”
Your last tender took three days to price with a 50/50 chance of winning. That’s a day and a half of your time wasted every time you lose. Your target margin is 25% and you’re achieving 19%. On £2.5m turnover, that’s £150,000 a year in margin erosion. £100/month is the cheapest hire you’ll ever make.
“What if it doesn’t work for my type of projects?”
I run commercial fit-out and refurbishment projects. But the platform covers the full spectrum — cost management, programme scheduling, H&S compliance, payment applications. Whether you’re doing shopfitting, M&E, civils, residential, or specialist subcontracting, the workflows adapt.
“I haven’t got time to implement another system.”
That’s exactly why this one works. No six-month rollout. No consultants. No three-day training course. You book an onboarding call, we set you up, and you’re running a live project within the week.
