See everything. Miss nothing. Act in time.
Purpose built for AECO. Purpose built to give you a genuine ROI. Purpose built to harness the data within.
Your project runs on systems that do not talk to each other. ARK connects them, builds one reasoning picture of the record, and highlights clawback events with the source attached. Every answer cited, permission-aware and auditable.
Grounded in truth.
“What's the specified concrete strength for Level 2?”
ARK: 40 MPa, as per Section 03 30 00, paragraph 2.1.1.
“What fire rating is required for the stairwell doors on floors 3-5?”
ARK: A 90-minute fire rating per Section 08 11 13, paragraph 2.3.2.
“Is this instruction a variation?”
ARK: Yes. It adds scope beyond Clause 4.2 of the subcontract. Notice is due within 14 days.

Every answer is cited to your project record. Intelligence you can act on and defend.
That's the difference between intelligence you can act on and intelligence you can defend.
Nobody is wrong. Nothing catches it.
A designer changes a detail. That invalidates a subcontractor's shop drawing, shifts a schedule activity, moves a pay application line, and changes what the operations team inherits at handover. Four systems, four companies, no thread between them. Everyone did their job.
21:47. A spec addendum lands.
Forty pages. Revision C. It arrives in an inbox on a Friday evening, and nobody opens it until Monday. No process failed here. There was simply no one whose job it was to read it that night.
A submittal is approved against the old spec.
Reviewed diligently, against Revision B, which is now superseded. The reviewer had no way to know. The two documents live in different systems and nothing connects them.
Steel is fabricated. Delivered wrong.
By the time anyone notices, it is rework, delay and, eventually, dispute. The expensive part was never the mistake. It was the weeks between the problem starting and anyone seeing it.
With ARK on the record, that Friday-evening addendum is read, matched to the open submittal, and flagged to its owner before Monday's approval.
Design, preconstruction, construction, handover, operations. One record across every phase and every party on the project. Every tool in AECO manages its own domain. None of them manage what crosses domains or what crosses companies.
ARK does.
ARK reads every system your project already runs on as one record: drawings, specs, BIM, RFIs, correspondence and contracts, across every company on the job. Ask it anything and the answer comes back with the document, page and clause attached.
See ARK answer, start to finish.
From question to cited answer on a real project record. This is the overview your whole team can watch before the demo.
One platform, built in three layers.
Each layer stands on the one before it. You cannot warn someone about a change you cannot see, and nobody acts on a warning they do not trust. So we build them in order, and we tell you which order we are in.
Connect and understand
Ask anything about the project and get an answer you can take into a meeting.
ARK reads the systems your project already runs on and builds one picture of the record. Drawings, specs, BIM, RFIs, correspondence and contracts, read together. Every answer arrives with the document, page and clause attached.
Watch and warn
Catch every change while the money is still recoverable.
Sentinel, ARK's Watch layer, keeps reading the record when nobody else is. When something changes, it shows you what is now at risk: which submittals, which schedule activities, which payment lines. It watches the contractual clocks too, so notice windows are never missed and entitlement is never lost to a deadline. Every warning carries a severity, an owner and the money at stake.
Do and act
Have the routine follow-up drafted, chased and logged. You keep every decision.
Once a warning is trusted, the work that follows it is mostly predictable: raise the RFI, notify the right people, log the position. ARK prepares it and a person approves it. Nothing reaches your systems of record without a human saying yes.
Whatever seat you hold, ARK pays its way.
General Contractors
Win more. Protect margins. Build smarter.
On a $100M project at 5% margin, recovering even 1% of un-raised variation entitlement is worth $1M. ARK makes that systematic.
Learn moreSubcontractors
Get paid for every instruction you're given.
Ask ARK to read your correspondence against the contract, and every instruction that adds scope comes back with the evidence attached. Notice goes in while there is still time to act.
Learn moreDesign Managers
Every package approved on evidence, not instinct.
Design managers carry a large share of the industry's lost week. ARK reconciles every source against every other and surfaces conflicts and gaps with full citations, so you adjudicate, not investigate.
Learn moreProject Managers
Every decision traceable. Every risk visible.
When a claim, audit, or gateway review asks why something changed, the answer is scattered across years of emails, RFIs, and minutes. ARK reconstructs the timeline from source evidence on demand.
Learn moreOwners & Operators
Inherit an asset record you can trust.
The party that carries the asset lives with every handover decision for decades. ARK gives owners a neutral, auditable view of the record they inherit, traceable across every company on the project.
