Decks, piers and cables inspected by air and cataloged by element. Fourteen spans photographed from angles a rope team cannot hold, then split into 2,300 elements with every defect ranked, located and carried forward to the next cycle.
Capture · Mission 06
The sheet above is a drawing of this. 10 capture waypoints, and every finding called as the aircraft reaches it — scroll sets the target, the mission keeps its own pace, and the page waits for it.
Sector · Bridges
Under the deck and out the other side, span after span: the soffit, the bearings and the pier faces no rope team can hold a camera on — fourteen spans and 2,300 elements, without closing a lane.
Inside a box girder and under a bearing shelf there is no aircraft and no rope. The condition of the diaphragms is whatever the last person who crawled in there wrote down, two years ago.
A tracked unit runs the box girder interiors and the pier chambers on a saved route, returning 360 imagery and readings at the same stations every cycle — no permit queue, no escort, no confined-space team standing by.
Deck soffit delamination does not show in a photograph. It shows as a warm patch an hour after the sun leaves the concrete, and only if somebody happens to be looking at the right time.
The soffit is flown for heat inside the cooling window and returned as a ΔT map tied to the element grid: every anomaly bounded, measured in square metres, and stacked against the same patch from the last cycle.
The inspection report is a PDF of 2,300 elements and 180 photographs. Six months later nobody can say which of the 41 defects got worse.
Every defect is an issue raised against a named element, with a location, a severity and a photograph, so the next cycle opens the same list and the trend is a column rather than an argument.

Inspection faces reached without rope access or a lane closure
The program owes the traffic nothing — fourteen spans are captured from the air and from inside the box while both lanes keep running, and every face lands on the same element register twice a year.
Twice a year, without closing a lane
Deck, soffit, shafts and abutments photographed from angles a rope team cannot hold. The model splits into 2,300 elements, and 96 % of inspection faces come back without rope access or a closure.
IMAGES 4 200 · STATIONS 216 · 0.6CM DETAILPier by pier, two passes each, in one evening
Each shaft is orbited at three levels from a 5.0 m standoff, holding the same 216 stations every cycle — so cycle four differences against cycle three instead of starting the argument over.
ORBIT 3 LEVELS · STANDOFF 5.0M · STATIONS 216In the cooling window, after the sun leaves the deck
Delamination reads as heat an hour after sun-off. The soffit is flown for heat inside that window and returned as a ΔT map tied to the element grid, every anomaly bounded in square metres.

A tracked unit runs the box interiors and pier chambers to the same stations every cycle, returning 360 imagery and readings — no permit queue, no confined-space team standing by.
SPAN 7 · STATIONS 14No. Fourteen piers are orbited two passes each in a single evening, the soffit is flown in the cooling window, and 96 % of inspection faces come back from the air or the gallery — traffic runs through all of it.
FACES 96% · CLOSURES 0The soffit is flown for heat after the sun leaves the concrete. The ΔT map bounds every warm patch on the element grid — 41 anomalies this cycle, up to 2.4 °C, each measured in square metres, not circled in marker pen.
ΔT 2.4°C · ANOMALIES 41Each defect becomes an issue against a named element with a location, a severity and a photograph — D-204's 40 mm spall at rank 3, D-118's 0.3 mm crack at rank 2 — and the next cycle opens the same list.
ELEMENTS 2,300 · RANKED 1–5The trend is a column, not a re-survey. The same stations every cycle mean the span 7 patch at panel D-11 reads 1.8 m², grew 0.6 m² since last cycle, and was ranked against the previous list by 08:00 the next morning.
PANEL D-11 · +0.6M² · RANKED 08:00The tracked unit runs it — 14 stations through span 7 alone, the same route saved and repeated, so the diaphragms are a current record instead of whatever the last person who crawled in wrote down two years ago.
BOX RUN · SPAN 7 · 14 STATIONSRead overnight on a structure like this one: the cycle's flight, the ΔT map, the box run and the element register against the previous list. Three of the 27 profiles wake up to it.

CONDITION
One mover on span 7: panel D-11's delamination grew 0.6 m² since last cycle while D-204's spall holds at 40 mm — the ranked list is cut, 41 anomalies, worst first, each on its element.
