Nine years and counting, €4B+, one platform. On time, on budget.
Frankfurt Airport's Terminal 3 has been under construction since 2014 tracked on PROBIS from the first quantity-survey calculation through today, still in progress.
Nine years of one program, by the numbers.
Figures below are cleared for publication directly from the Frankfurt Airport engagement.

Decade-plus timelines
Nine years and counting at Frankfurt alone — long enough for the original spreadsheet, its author, and the assumptions behind it to all be gone.
Thousands of moving parts
45,000 budget elements, 2,500 contracts, and 1,000 procurement packages don't stay reconciled in a spreadsheet built for one project at a time.
400+ companies, one number
With 400+ companies and up to 3,000 workers at peak involved, everyone needs to be working from the same cost structure, not their own version.
A portfolio report that used to take a week
Before PROBIS, producing a portfolio-level cost report was roughly a week of manual work — now it's one click.
Three separate systems, reconciled by hand now one platform, one click.
Three modules, from QS calculation through completion.
The Airports engagement runs on three modules specifically — not all six — covering the full lifecycle from quantity-survey calculation through completion.
Calculate
Quantity-survey-based cost calculation across 45,000 budget elements and 45 sub-projects, from the earliest planning stage.
Contract
Contracts and commitments tracked from before construction starts, not after the first invoice arrives.
Control
Forecast vs. actual, held to the line item, closing within roughly 2% of the approved budget.
Where PROBIS's AI earns its keep, nine years and counting.
Early Warning System
Flags a cost or schedule deviation against threshold the month it appears, not the quarter a report surfaces it.
AI-Powered Benchmarking
Benchmarks a data-center build against comparable projects, not just this one.
Bidirectional Calculate & Control
When a capex input shifts, downstream KPIs recalculate automatically instead of waiting for the next manual update.
45 sub-projects, on one dashboard.
Illustrative only — figures below are fictional and do not represent the program's actual line-item data.
One package is drifting 10% over — flagged automatically, three quarters before the original plan would have caught it.
PROBIS is the central interface for all our project data, enabling multi-project management that meets today's demands.
