§ 03 — How It's Built: The Modules

Three modules, from QS calculation through completion.

app.prob.is/calculate

Calculate

QS calculation, from day one

Quantity-survey-based cost calculation from the earliest planning stage.

app.prob.is/contract

Contract

Every package, from pre-construction

Contracts and commitments tracked from pre-construction, not from the first invoice.

app.prob.is/control

Control

Cost control through completion

Forecast vs. actual, reconciled continuously, line item by line item.

§ 04 — How It's Built: The AI

Where PROBIS's AI earns its keep on this program.

AI Report Builder

Productive

Decide · AI Report Builder — build any report from a prompt. A controller writes a prompt once for a monthly variance report across three projects; from then on it updates itself automatically as new cost data arrives.

§ 05 — How It's Built: The Dashboard

45 sub-projects, on one dashboard.
