Less checking. Stronger numbers. More projects per expert.

01

Find every change

Every reissued sheet compared against the last, even renumbered ones. Additions, deletions, credits, and the text-only changes nobody clouded.

02

Prove every price

Every claimed line priced from your own agreed rates and go-forward pricing, the source cited on every figure. Your clients keep money they would have paid out.

03

Multiply your experts

The measuring work is automated, the judgment stays with your professionals. The same cost managers cover more projects.

M-502 ADD CDU hookup connections, 12 units 0 360 HR – $459.61 $214,800 $165,462 $49,338 Assessed

The deletion is under-credited: 6 of the 14 hookups Rev C removes are credited, leaving 8 EA of the removal unreturned.

Demolition of the full plenum is claimed; Rev C reuses the plenum with closure pieces at the deleted CRAH positions, so the demolition scope needs review.

Cost consultancies and owner’s reps

Cover more projects with the same experts.

Your pitch is that you save clients multiples of your fee. Craics instruments that claim, and takes the ceiling off how many projects each expert can carry.

01
The assessment builds itself.

Every claimed line arrives checked against the agreed rates, the scope of work, and the drawings, with the backup cited.

02
Savings you can show the client.

Savings computed natively, submitted against assessed on every line, with the reason recorded.

03
Capacity without hiring.

The measuring work is automated, so the same cost managers carry more projects.

Owners and developers

An independent number before you sign.

Change orders arrive priced by the other side of the table. Craics gives you your own number for every one of them, built from your own contract, before you approve anything. Software you standardise on travels down the project: your owner’s rep and your contractors work to it.

01
Every change order gets a full check.

Rates, markup, quantities, scope, and backup on every line. You stop paying for what you shouldn’t.

02
You always know where the money stands.

Budget, allowances, and contingency tracked live as changes settle.

03
Close-out ends with the work.

Final accounts accrue as changes settle, so the reconciliation is already done when the work is.

Evidence moves change orders.

Craics sits on the owner’s side of the table, and the engine it runs takes no side. Your change orders move through review on evidence instead of argument.

01
Reviews stop stalling.

A claim that lands in an evidence-linked register gets ruled on, because the small changes stop being arguments.

02
Under-claims surface too.

The same check that catches an overpriced line catches the cost you missed.

03
The record protects everyone.

When every number carries its source, disputes shrink and the final account is largely agreed.

What does not get checked gets paid.

Why we exist

The burden of proof belongs on the number, not on the person questioning it.

A change order arrives priced by the party asking to be paid. The professional questioning it starts from behind, with a stack of drawings, a contract, and not enough hours. That asymmetry is the whole problem, and it is the reason so much money in construction moves on the weaker argument rather than the better one.

Craics puts the evidence on the number instead. It is built by people who manage construction cost for a living, not generic AI pointed at a job site. The engine takes no side: an evidence-linked register serves everyone at once, because when the small changes stop being arguments, attention goes where the money is. The system does the proving. The professional does the deciding.
