~2% of the budget. On schedule. From pre-construction onward.
A Google data center in Hanau, developed by the NDC-GARBE joint venture, closed within approximately 2% of its approved capex with PROBIS in from pre-construction, running QS, pro forma, and cost control from the start.
All figures below are approximate, as supplied.

Data centers compress a normal build timeline into a race.
Pre-construction is where the budget gets set
By the time steel is on site, most of the capex decisions that matter are already locked in — a pro forma built on assumptions, not a live cost structure, is the wrong tool for that stage.
MW and m² both have to work
IT load capacity and floor area are negotiated together with the end user — a cost overrun in one changes the economics of the other.
Network proximity is a cost variable, not just a location decision
Distance to a hub like DE-CIX Frankfurt affects connectivity cost assumptions baked into the original business case.
The end user isn't the developer
Google and NDC-GARBE need the same numbers, from two different vantage points, without reconciling two separate cost models.
Three separate systems, reconciled by hand now one platform, one click.
Four modules, engaged from pre-construction.
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.
Rent & Sell
Revenue control across leasing, sales, and additional claims, reconciled against the cost side.
Manage
Board-ready reporting and workflow automation, generated on demand rather than assembled by hand.
Keeping a ~2%-variance outcome repeatable.
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.
Pre-construction to close, on one view.
Illustrative only — figures below are fictional and do not represent this project's actual budget data.
One package is drifting 10% over — flagged automatically, three quarters before the original plan would have caught it.
A client quote from Peter Pohlschroeder has been requested for this case and is not yet confirmed. That slot is left empty here rather than filled with a paraphrase.
