Fixed-scope engineering,
priced before we start.
Every engagement is a concrete deliverable a senior power-systems engineer produces for your site — not retainer hours. Most halls begin with the Density Screen, which credits in full against the study it usually leads to.
Fixed fee, named artefact, no hourly billing.
Start where your question is. Most halls start with the screen, because it costs less than the meeting you would otherwise have about whether to have a meeting.
Density Screen
A five-day screening opinion on one hall: what binds first, how many racks of your target platform it carries as it stands and after the costed ladder, which item sets the date, and the list of inputs nobody has measured.
- Artefact
- Density Screen document (HTML + Markdown), the first six rungs of the headroom ladder, and a data request you can send to your own engineers verbatim.
- Turnaround
- 5 working days
- Price
- €4,500
Capacity & Density Envelope Study — deposit
€9,000Reserves senior engineering capacity for the full study: the complete constraint ladder, every architecture compared, time to power, sensitivity, economics and a machine-readable model pack you keep.
You receive
Envelope Study (HTML + Markdown), model_pack.json, and a 90-minute walkthrough with your engineering team.
Procurement Specification
€18,000The study says what binds and what relieves it. This is what you send to suppliers: a tender-ready technical specification for one relief, with every duty derived from the capacity model and quoted at your site conditions — then your bids compared in racks and weeks, not only in euros.
You receive
Technical specification (HTML + Markdown), a machine-readable response schedule, and a bid comparison against the capacity model showing what each response does to the energisation date.
Portfolio Screen — deposit
€15,000Five to fifteen halls ranked by deliverable compute, time to power and capital cost per rack, under one methodology so the ranking is comparable.
You receive
Portfolio Screen document and one model pack per hall.
Hall Watch
€6,000 / quarterWe keep your hall's model live. Every quarter — and whenever you update an input — it is re-solved and you get a change note: what moved, which input moved it, and whether it changes the decision.
You receive
A quarterly change note naming the inputs that moved the answer, plus an unlimited re-run whenever you update the hall's numbers. Nothing material to report is itself a reportable answer, and we say so in three lines rather than padding it.
Not sure which? Run the free qualifier first. It names the constraint that binds your hall and the inputs nobody has measured, and it costs nothing. If it tells you the answer is no, that is the cheapest no you will ever get.
Not sure which step to start with?
Run the free Time-to-Power comparison on your hall: racks as found and after relief, what binds, and the date to full capacity with the evidence class behind it. Save it to a project and send the read-only page to whoever approves the spend; they can commission the next step from it, at the prices above.
