Every decision, defensible.
ARK rebuilds the full evidence chain on demand, cited to drawings, RFIs, emails, instructions, minutes, and comments. Project history becomes a question you can ask, instead of a search you have to run.
Request a DemoYour project's full history, ready to answer any question.
Everything a project decides leaves evidence, in drawing revisions, RFI threads, emails, minutes, and comments. ARK holds that whole record, connected and cited, so when a claim, audit, or gateway review asks why did this change, the answer comes back with the evidence chain attached. Teams that answer from evidence negotiate from strength, close reviews cleanly, and keep decisions moving.

For leadership
For project leadership: decisions that stand up to the client, the auditor, and the adjudicator, with the contemporaneous record to prove it.
Evidence assembled before the engineer opens the RFI.
ARK treats each RFI as a query and retrieves the relevant drawings, specs, prior decisions, related RFIs, and meeting records. The responder reviews and answers instead of hunting and assembling, and because prior answers are there to find, the same question stops being asked on every package. Shorter queues, fewer blocked decisions, and more engineers able to answer with confidence.
What you get
- Responders start from assembled evidence, not a search
- Repeat RFIs fall as prior answers surface
- Shorter queues mean fewer blocking issues on programme
Why did this drawing change, answered with a cited timeline.
ARK reconstructs decision and change histories from source evidence on demand, returning a chronological chain with citations to drawings, RFIs, emails, instructions, minutes, and comments. Audits and gateway reviews get evidence, not recollection. And project history survives staff turnover, because it is machine-held, not person-held.
What you get
- Any decision re-justified with auditable evidence
- Claims built from a cited, chronological record
- Project history survives staff turnover
Know what a change touches before you make it.
A revised slab thickness ripples through structural details, MEP coordination, finishes, schedules, BOQs, submittals, and programme. Ask ARK about a proposed change and it maps the relationships between artifacts, identifying the downstream items that reference, depend on, or coordinate with it, with commercial impact named. Changes propagate deliberately, and go or no-go decisions are made with cost visibility before the change is committed.
What you get
- Changes propagate deliberately, with a record
- Pre-change cost visibility supports go and no-go decisions
- Coordination issues from incomplete propagation drop away
What runs today, and what comes next.
What ARK does today
Ask what changed, when and on whose instruction, and ARK returns a chronological evidence chain: drawings by sheet and revision, specifications by clause, RFIs by number, and meetings by date.
What Sentinel adds next
Keeping the trail current without being asked is what Sentinel adds next: watch packs that follow a decision as it moves, and alerts when new correspondence changes the picture.
