The AI operating system
for construction.
ConstructEther replaces the fragmented stack of seven tools with one AI-native commercial backbone — built for the firms that price work and run projects in an industry that can no longer hire its way out of its commercial shortage.
Why construction. Why now.
Three structural shifts have compressed the window. The platforms that win it set the standard for the next decade.
Senior talent has become a permanent constraint.
Senior commercial salaries have outpaced fee scales for a decade — and there is no pipeline of replacements coming. The industry cannot hire its way through the shortage. AI is the only intervention that scales output without scaling headcount.
The Building Safety Act has rewritten the rules.
Golden thread evidence is mandatory. Gateway approvals are personal-liability moments. The firms with the cleanest commercial workflows will inherit the work — and everyone else will pay the audit cost, repeatedly, on every project.
AI capability has crossed the threshold.
Take-off, BoQ generation, scope-gap detection, live cost reconciliation — operationally viable today, not future capability. The first platforms to unify them as a single commercial backbone will set the standard for the next decade.
Three ways margin walks off site.
And what it costs to ignore them.
Pricing in the dark
Bidding off spreadsheets and gut feel. A 2% error on a £500k package is £10k of margin — every time you submit.
Chasing payment
Late applications. Missed notifications. Unpriced variations. The Construction Act is on your side — but only if your paperwork is.
No QS in the room
When the main contractor's QS fires a pay-less notice, who responds? If the answer is "next week", you're already losing.
One platform. Four engines.
Each module is built around a single commercial outcome — and they share data, so what you cost flows into what you tender, what you tender flows into what you build, and what you build proves compliance automatically.
Tender Intelligence
Drawings in. Priced bid out. Drag-and-drop take-off, AI quantity scaling, and live rate libraries compress days of work into hours — with audit trail baked in.
AI-PoweredCommercial Engine
Cost plans, valuations, variations, and final account — all running off the same dataset. Margin moves are visible the moment they happen, not at the end of the month.
Live DataProject Delivery
Programme, RFIs, instructions, and site progress in one place — synced with the commercial side so a delay shows up as a forecast, not a surprise.
Real-TimeCompliance
Building Safety Act, Golden Thread, CDM, and QA all evidenced as you work — not retrofitted the night before the auditor arrives.
Built-InFor the firms that turn drawings into buildings.
ConstructEther is built primarily for large trade contractors carrying multi-million-pound packages — and the main contractors, QS firms, and developers who depend on them.
Contractors
Price bigger packages, run leaner sites, and prove compliance on the projects that move your business forward.
Concrete · Light gauge steel · Structural steel · Partitions · Dry lining · M&E · Cladding · Curtain walling · Groundworks · and moreMain Contractors
Tender, deliver, and prove compliance from one platform — with margin and programme visible to leadership in real time.
QS & PM Firms
Win more bids in less time. Run accurate cost plans and valuations without juggling four spreadsheets and an inbox.
Developers
One source of truth across consultants and contractors. Know what's costing, what's slipping, and what's at risk before the next board meeting.
From a stack of workarounds to one platform.
- Take-offs in one tool, pricing in another, programme in a third.
- Margin slips invisible until the monthly board pack lands.
- Compliance evidence reconstructed from email chains at audit time.
- Tender turnaround measured in days, not hours.
- Knowledge walks out the door when senior staff leave.
- One platform from drawing receipt to final account.
- Margin and forecast move live as decisions are made.
- Audit trail and Golden Thread evidenced automatically.
- AI-assisted bids returned in hours, not days.
- Standard rates, methods, and templates owned by the business.
Four steps. One workflow.
Tender — drawings to priced bid in hours.
Drop drawings in, run AI take-off, apply your rate library. ConstructEther scales quantities, flags outliers, and produces a fully auditable bid your team can sign off in a single sitting.
- AI-assisted quantity take-off from PDFs and DWGs
- Reusable rate libraries and supplier benchmarks
- Bid pack generated with full working backup
Win — convert with confidence.
Track win/loss, learn from every bid, and standardise the moves that close. Your tender history becomes a competitive asset, not a folder full of PDFs.
- Win/loss tracking with reason codes
- Margin sensitivity built into every submission
- Pre-construction handover with zero rework
Deliver — programme, cost, and progress, joined up.
Live programme status, valuations, variations, and site progress all flow off the same dataset. Margin and slippage become forecasts you can act on, not surprises you have to explain.
- Live valuations and CVRs
- Programme tracking with earned-value alerts
- Variation register with auto-priced impacts
Comply — Golden Thread, by default.
Building Safety Act, CDM, QA records, and the Golden Thread are evidenced as you work. The audit trail isn't a separate task — it's a by-product of using the platform.
- Building Safety Act and Golden Thread coverage
- Document and revision control with full lineage
- Inspection records, RFIs, and TQs in one register
John Ellis
John has spent over 25 years on construction sites — starting as a labourer for bricklayers and plasterers, working through the trades, and qualifying as a Quantity Surveyor. He's delivered in excess of £275 million of construction works for some of the UK's largest contractors, and continues to support self-builders and developers nationwide. Twenty-five years in, the conclusion was unavoidable: construction doesn't have a software problem — it has a fragmentation problem. ConstructEther is built to fix it.
