Ninety-two thousand square metres of slab, forty-six tilt-up panels cast on top of it, sixty-eight dock doors and 42,000 pallet positions that all depend on a floor holding FF 55. Ground Reality surveys each pour at +24 hours against the design plane, so the one station that needs grinding is found before the racking crew is booked.

Sector · Logistics
Ninety-two thousand square metres read in one governed pass — down the dock face counting sixty-eight doors as they cycle, in through the gable the tilt-up has not reached, along the sorter and out between the rack faces at FF 55 / FL 35 — then the unit walks the dock and captures what a yard walk never files: the leveller lip, the apron joint, the trailer on the swing.
The slab is the asset. A defined-traffic aisle that misses FF 55 is a turret truck that slows for the life of the building — and the reading usually turns up days after the concrete has gone hard and the screed crew has left the site.
Each pour is surveyed at +24 hours and meshed against the design plane, station by station on the 3.05 m grid. Departure reads in millimetres over the piece of floor it was taken on, so one point gets ground on a Tuesday instead of a bay getting argued about in October.
The slab is also the casting bed and the laydown yard. Panel 31 ends up stacked behind a racking delivery, the 300-tonne crawler is on hire by the day, and the lift sequence was drawn before either of them arrived on site.
Laydown is planned and tracked on the same capture as the build: what is cast, where it is stacked, and what the crane can reach on the shift it is being paid for. Panels get lifted in the order they were cast instead of the order they can be dug out of the yard.
Forty-two thousand pallet positions are set out from a drawing of a building poured six months earlier. An aisle 15 mm narrow or a column 30 mm proud is found by the turret truck, on the day the tenant wants to store product in it.
The as-built slab, columns and roof steel are registered against the racking model before the first frame lands. Aisle width, column clash and clear height under the joist read as measured deltas against revision — flagged from 25 mm, at the row they happen on.

The program runs on the slab's clock — the pour behind the screed at 22:10, the survey at +24 hours, the racking crew booked for Friday. Everything the building will ever do is decided by the floor first.
Each morning, over the slab, the yard and the apron
The flight reads what stands and what is stacked: the dock wall and its apron surveyed together, and the casting bed's laydown mapped — because on a tilt-up job the slab is also the yard.
DOCKS 68 @ 3.66M · LAYDOWN MAPPED · 1.1CMEvery pour, at +24 hours
Each pour is meshed against the design plane, station by station on the 3.05 m grid, the morning after it goes down. Pour 214's station 7 read 3.9 mm low — one point ground on a Tuesday, not a bay argued about in October.

Forty-six panels cast on the slab they will enclose, lifted in the order they were cast instead of the order they can be dug out of the yard — the 300 t crawler is on hire by the day, and the sequence is read off the same capture.

AISLE 2.78M · CLEAR 12.20M · TOL 25MMThe +24 hour survey does. Pour 214 was read at twenty stations on the 3.05 m grid the morning after it went down; station 7 sat 3.9 mm low and was ground by 07:20, before the racking crew set row 4 on top of it.
STN 7 · 3.9MM LOW · GROUND 07:20Hold it and prove it. Pour 214 gauged FF 57.4 / FL 36.1 against the FF 55 / FL 35 spec, and every pour lands on the same record — 92,000 m² of slab carried on one flatness ledger instead of a drawer of reports.
FF 57.4 / FL 36.1 · SPEC 55/35The capture does. What is cast, where it is stacked and what the crane can reach are tracked on the same record as the build, so 46 panels at 42.5 t lift in cast order — and the 300 t crawler swings on the shift it is paid for.
PANELS 46 · 42.5T · CRAWLER 300TMeasured before the first frame lands. The as-built slab, columns and roof steel register against the racking model: 2.78 m aisles, 12.20 m clear under the joist, and any delta past 25 mm flagged at the row it happens on.
