Four production halls, a 10-tonne crane on its rail, and block foundations that were bought against a tolerance of ±2 mm. The building exists to serve the machines — Ground Reality carries the anchor set-out, the revision the block was poured to, and the services under the floor on one record, so the line sits down the first time it is craned in.

Two hundred and twenty metres of production hall, flown down the middle of LINE 4 at sixteen — over the robot cells, under the haunch, and straight at a ten-tonne crane walking the other way with an eight-and-a-half-tonne machine slung under it. Two point two metres of clear air, measured. Then the unit walks the line and reads the eight anchors the machine has to sit on.
The machine was bought against a foundation tolerance of ±2 mm. Once grout goes in, an anchor set 4 mm high is a coring rig, a vendor claim and a line that misses the start date it was ordered for.
The as-set survey runs as a gate on every block: eight anchors, departure from design in millimetres, the worst one named, signed before the grout is booked. The evidence lands against foundation F-12 and the dated frame that shows it, not in an email attachment.
The machine builder issues rev G of the anchor plan while the block is being poured to rev E. Nobody on the pour crew knew there had been a rev F, and the pocket now sits 60 mm from where the bolt has to be.
One controlled set: the current revision is what the field opens, superseded sheets are stamped, and a change lands in front of the crew that has to build it. Every block carries the revision it was actually poured to, on the record, for the day the vendor asks.
Pits, ducts, cable trench and cooling runs are buried the day the machine lands on top of them. Two years later an upgrade needs the service route, and the only record is a drawing nobody has touched since tender.
Each hall is walked before the floor closes and again before the machines are set — frames pinned to the plan within ±0.3 m, dated, at the same vantage points. The trench stays open in the record long after it is closed on site.

The program runs on the machine schedule — the pour, the anchor set, the grout booking, the SAT. Every instrument on this list answers the same question: does the line land on day one?
Before each floor closes, and again before machines set
Pits, ducts, cable trench and cooling runs are walked while they are still open — frames pinned to the plan within ±0.3 m — so the trench stays standing in the record long after the 250 mm floor closes over it.

The pass runs the halls at crane-rail level — portal frames, the 10 t crane on its rail, line 4's stations — so the building the machines are landing in is measured, not assumed.

A total station between the blocks shoots every anchor's departure from design level in millimetres and names the worst. F-12 closed at −1.9 mm, at B3 — signed before the grout was booked, re-shim nil.

The same instrument that surveyed the anchors watches the module come down, so the shims cut from the survey are the shims that fit. M-312 landed at 06:05 with grout booked for 09:30.

Foundation vibration and anchor torque ride the record through to the SAT, so the block is proven quiet under the machine it was poured for.

F-12 · MAX −1.9MM · TOL ±2.0MMThe field only opens the current revision. Rev G lands in front of the pour crew the day it is issued, superseded sheets are stamped, and every block carries the revision it was actually poured to — for the day the vendor asks.

F-12 gates the 06:05 lift: the as-set survey closes at 05:40 — worst anchor 1.9 mm low at B3, inside the envelope — so M-312 lands on schedule and the grout keeps its 09:30 booking.
