120 days of what?

A prefabricated AI data center in Jinan was built in 120 days. The number is true. It starts the clock late, and then compares itself with a clock that starts early.

14 October 2026

The claim

In January 2025, Inspur Information announced that its Compute Factory in Jinan3 had gone into operation. The release is built around one number: from construction to official operation, "only 120 days"1.

The rest explains how. The facility is 119 prefabricated containers with a total power draw of 10 megawatts1. Its prefabrication rate is 90 percent1, and equipment was integrated and tested in the factory while civil works on site went on in parallel1. All of these figures are the vendor's own. I have found no independent record of the build.

One fact belongs up front. Inspur Group was added to the US Entity List in March 2023, and six of its subsidiaries in March 20254. This piece is about how a schedule claim is measured, not a recommendation of the vendor.

Where the clock starts

Nine days after the release, TMTPost published a longer account of the same project. One sentence is worth reading whole: from planning through factory production, foundations, lifting and commissioning, "the project took nine months in total to deliver. Excluding the early planning period, actual construction to operation took only 120 days."2

So the 120 days is true, and it is the second part of a nine month job. Roughly five months of planning came before the clock started.

Translations from the Chinese are mine.

The comparison uses two different clocks

The release supplies its own benchmark: a traditional data center's "planning and construction cycle is usually more than three years."1 That clock starts at planning. The 120 day clock starts after it. Side by side, they compare one project's construction with another project's planning and construction together.

Measured the same way, it is nine months against more than three years. That is still a quarter of the time or less, so most of the gain survives. The headline just claims a bigger share of it than the like for like number supports.

Where the time went

Prefabrication does not delete work. It moves it. Running the factory and the site in parallel is where most of the compression comes from.

But a factory can only build what has already been decided. Every container has to be specified before it is made, so design decisions a conventional build can settle months into construction have to be settled first. The five months before the clock are not overhead around the 120 days. They are what made the 120 days possible.

Huoshenshan showed the same thing at hospital scale: its ten days began from an existing design, adapted from a Beijing hospital built in 2003. In the terms of the seven flows, both builds fed the information flow before the clock started, then counted from the moment it was fed.

The clause about power

Power gets a single clause. The modules "can run independently once connected to mains power, network and water."1

Once connected. Neither the release nor the longer account says when the connection was requested or how long it took. A factory can compress everything inside the fence. It cannot build the line that reaches the fence.

For many American projects, that clause is most of the schedule. In June, ERCOT was tracking more than 438,000 megawatts of large load requests5 on a grid whose all-time peak is 91,089 megawatts6. A 120 day build that waits two years for power is a two year build.

What to take to work

Ask where the clock starts: first planning meeting, design freeze, contract award, factory slot, or first day on site.

Ask where it stops: built, energized, commissioned, or carrying load.

Ask what runs outside it: planning, the factory queue, the power connection. If a number starts at construction, its benchmark should too.

A note on the last prediction

On 15 September, How a quarter becomes a year predicted that if Stargate UAE announced its first 200 megawatts by 30 September, the announcement would use a completion verb rather than a load verb. Nothing was announced. As of 14 October, I could find no announcement from G42 or its partners7. The prediction was not right. It was untested. That piece promised a follow-up in the first week of October. This is it, a week late.
