Structural lead for a cable-stayed pedestrian and light-transit crossing over a live shipping channel, delivered under an active marine-traffic exclusion window.
Every marine operation had to fit inside a four-hour tidal and shipping-traffic window, which meant the erection sequence for the deck segments was really a logistics problem wearing a structural-engineering costume.
We modelled eight alternative lift sequences before settling on a balanced cantilever approach launched from both banks simultaneously, cutting the number of required marine windows from thirty-one to nineteen.
The wind-tunnel results came back with a vortex-shedding concern at low wind speeds that the original concept design had not flagged — resolving it meant a fairing redesign that added six weeks but avoided a much larger retrofit risk after opening.
