Preconstruction risk, validated

Know your Stage 4 package
is tender-ready. Before your price is.

Ankylo checks your design and tender documents for the gaps, mistakes, and missing information that turn into costly variations at Stage 5.

You're on the list. We'll reach out as early access opens — usually with a couple of quick questions about your current package review process first.

Why it matters

The same gap costs differently depending on when you find it.

A missing detail caught during design review is a phone call. The same gap discovered on site is a variation, a delay, and a dispute.

Caught at Stage 4

A query

Flagged before tender, resolved with the design team in a single conversation. No exposure, no rework.

Caught at Stage 5

A variation

Discovered on site or during pricing. Now it's a change order, a programme hit, and a harder conversation with the client.

How it works

Three steps, before you commit to a price.

Upload the package you already have — nothing to reformat, nothing to restructure.

Upload the package

Drawings, specifications, and reports — as issued, in whatever format your design team sent them.

Ankylo cross-checks it

Every document is checked against the others for missing information, inconsistencies, and gaps that create risk at tender.

Get a risk score and fixes

A tender readiness score, every flag ranked by severity, and what to do about each one — before you price it.

Tender readiness 62 / 100

High severity

Fire strategy drawing missing from the issued set — referenced in the specification but not included.

Medium severity

Window schedule (Rev C) shows different glazing spec than the M&E drawings — needs confirming before pricing.

High severity

Structural GA and architectural GA disagree on a column grid line on the ground floor.

Positioning

More eyes on every package, without more headcount.

Ankylo does the exhaustive, repeatable cross-checking. The judgement calls stay exactly where they belong.

Who's behind it

Built from inside the industry, not outside it.

Ankylo is built by an operational construction manager working inside one of the UK's largest main contractors, managing the exact Stage 4 handovers and tender packages this tool is designed to check. It's built to reflect how SME teams actually work — not a generic plan-checking tool adapted for construction.

Questions

Before you join.

What happens to our drawings and documents?

Your package is used only to generate your review — never to train models, and never shared beyond your account. Full data handling terms will be published before early access opens.

Does this replace our design manager?

No. Ankylo does the exhaustive, repeatable cross-checking across a package. The judgement calls — what a flagged risk actually means for the project, trade-offs, and what goes to tender — stay with your design manager.

Is this only for RIBA Stage 4 packages?

Stage 4 is the primary focus, since that's where the highest-cost gaps typically get missed before tender. Coverage for other stages is on the roadmap based on waitlist demand.

How accurate is the analysis?

Ankylo is built to support professional review, not replace it — every flag comes with the reasoning and page reference behind it, so your team can verify and act quickly rather than taking it on faith.

What will it cost?

Pricing is being finalised with input from the waitlist itself. Expect it to be priced per package reviewed, not per seat — built for how SME teams actually use it.

When does early access open?

No fixed date yet — we're building the waitlist first. Everyone on the list gets a couple of quick questions about their current review process, then early access as pilot spots open up.
