Founder's project experience. Our founder took part in the construction design and site work on this project. It was carried out as part of another company's team, not under the Yan & Partners name.
The Island Eastern Corridor runs over the sea on piles, and several of its pile caps needed repair.
The team designed a steel working cage from 40 × 40 mm angle that clamps around each pile cap, with channel-steel runners and ladders, so repair crews had a stable platform at every cap without scaffolding from the seabed.
From the drawings
The repair platforms hang from the pile caps and tie beams of piers P-42, P-43, P-49, P-50, P-73 and P-74: 203 × 203 × 46 UC hangers, 152 × 152 × 23 UC struts, channel ribs at no more than 450 mm centres and a 6 mm steel deck, bolted with grade 8.8 M16 and M12 bolts, with removable hangers kept above sea level. The structure was revised in June 2022. Every face of every cap was measured for the repair area.
