As the viaducts pass through Ocean Park and Wong Chuk Hang Stations and on to Ap Lei Chau much of their length is shielded by glazed noise barriers. These also support the Overhead Power Lines for the trains.

As the viaducts of the South Island Line pass through dense urban areas we were asked to design noise barriers along much of the length. With Aedas, Atkins developed an integrated solution that supported the overhead lines supplying power to the trains, allowed hot air and smoke from any fires to vent out and gave views out for the passengers.
Hopefully also it is also interesting to look at from outside. It is difficult to hide a viaduct but we came up with a gradated green tube of glass and metal facets that then shifts colour as it enters the two stations - which each have their own colour.

ound Pressure Levels (SPL) between -3 dB (pressure diminished with the respect to incident) and +6 dB (pressure amplified with respect to incident) are shown. The pressure is not displayed in the volume of the bones (gray regions) or in the volume of the air spaces or sinuses (black regions). (A) is a transverse section through the TPC with labels indicating the involucra (i) of the tympanic bulla and the expanded portion of the squamosal (sq); (B) is a coronal (horizontal) section through the TPC, at the level of the tympanic bullae (tb). Note the amplified pressure amplitude near the dorsal surface of the tympanic bullae (tb) from a reflection off of the squamosal bones (sq).

The steel roof of OCP was developed rapidly at the end of the project after a change in brief removed the need for a solid concrete roof. I was very pleased with the result which I hope will be simple an elegant.
The primary structural element is the central concrete column. The steel connects at the head with a moment connection, stiffening the column into double curvature during typhoons. As a result the perimeter steelwork is lightweight, allowing better views out to the Ocean Park.

The huge central support for the Y-shaped section of viaduct where the tracks split. The bearing shelves on the depot and station can be seen beyond. Control of horizontal movements was a key concern in the design of this area.

In the photo on this page, Jenn is teaching a problem in the use of rebar in concrete.
She is assistant teaching at U.C. Berkeley at the time.
Jennifer Masich Lynn specializes in structural engineering and teaches at Cal Poly.
Marco brought his structural plan for Bliss Dance to her and asked her to criticize it.
She hasn't done the calculations yet but she told me that the configuration looks encouraging.
Most of the steel in the piece is quarter inch, but it gets thicker and thicker as it goes down to the supporting leg.
At the bottom, it is very heavy…

Marco will end up with three sizes for the piece:
- the original, which is life-size or three-quarter size in bronze.
- an intermediate size- 13 feet- in clay to add detail.
- the finished, 40 foot piece.

In the photo, above, Jenn is a T.A. at U.C. Berkeley in 1999. She is teaching a course called Mechanics of Materials. This class is on the behavior of concrete under stress.
