From first‑principles build‑up to defensible estimate — and on through whole‑of‑life forecasting. Now augmented with AI that turns drawings and models into traceable estimates in days, not weeks.
Cats carries a project from the tender that wins the work, through the monthly cost review that closes it out — with the same data, governance and rate libraries the whole way. No silos. No re‑keying.
Bottom‑up build‑up with a 9‑level assembly, rate libraries and full multi‑user control.
The winning tender flows into the monthly review — traceable, owned and defensible.
Drawings and models become a clean, traceable first‑pass estimate — with AI review agents.
A true multi‑user estimating system: hundreds of estimators creating and modifying live tenders at once, on a single source of truth, with the security and audit trail estimating managers actually ask for.
A construction estimate isn't a single number — it matures with the design. Industry practice recognises five estimate classes: from an early order‑of‑magnitude figure used to test feasibility, through to the definitive estimate that becomes a contracted price. Each class carries a different expected accuracy and demands a different depth of build‑up.
Most teams sketch early estimates in spreadsheets, then rebuild them in a different system once the design firms up — losing structure and history at every handover. Cats runs all five levels in one environment.
The build‑up, rate libraries and assumptions from one level flow straight into the next instead of being keyed in again — so each stage starts from the last, not from scratch.
Every level keeps the same audit trail. Feasibility number or final tender, any figure traces back to the design it came from and the day it was made.
“Cats is a true multi‑user estimating system that allows real‑time analytics of live tenders. The pragmatic and solid security settings are industry leading. They are designed for what Estimating Managers want.”
Richard Scott — Group General Manager, John Holland GroupBuilt for the monthly Cost‑to‑Complete review cycle. The same bottom‑up rigour that won the job now keeps the forecast defensible — every month, all the way to handover.
Every quantity, rate, assumption and calculation method recorded in‑system, with a full audit trail across every revision.
Multi‑layered, register‑based security keeps the right eyes on the right data — clear ownership of every line.
Bottom‑up methodology and a frozen library of rates per forecast keep results consistent and reproducible.
Side‑by‑side variance views and drill‑downs from cost code into resource make month‑on‑month review fast.
“Cats eliminates project gaps by ensuring consistency from the initial estimate all the way to the final monthly cost review.”
