Causeway Bay seawater pump house intake

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.

Large buildings along the Causeway Bay waterfront draw seawater for their cooling systems through intakes below the waterline. The team inspected the intake, recorded its condition in a 3D inspection drawing, and prepared the construction and dimension drawings for the steelwork that was then fixed to the intake underwater.

From the drawings

The intake belongs to the cooling pump house of Windsor House. We built a temporary bulkhead in front of its three Ø400 mm intake pipes, from +5.00 mPD down to the seabed at about −1.00 mPD, with steel posts and walers on M30 stainless bolts, panel bays of 1,530 and 1,220 mm, and cement sandbags packed around the pipes. Two ways of extending the pipe sleeve were drawn: welded on shore, or welded underwater.
