At the end of the platforms the roof needs to connect back to the concrete frame. Unfortunately the cast-in bolts were missed out and post-drilled anchors used - I hope they cut the ugly projecting threads off!
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.

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.

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.

Booth-Kelly Railroad Bridge (1882), now called Hayden Bridge, is a single span Whipple through truss spanning the McKenzie River in Springfield. A Whipple truss is a (stronger) variation of the Pratt truss, also called a “Double Intersection Pratt”, characterized by diagonal tension members crossing adjacent verticals, thereby spanning two panels instead of just one for the Pratt truss. It is considered the oldest surviving bridge in Oregon, while rare and significant for its wrought iron Phoenix columns. This bridge has been moved once. Originally built in 1882 by Phoenixville Bridge Works at Corrine, Utah, it was dismantled and relocated in 1901 to its current location to serve the since abandoned Weyerhaeuser Logging Railway. The bridge was abandoned in 1987, then decked for pedestrian use and reopened in 2019. Notable also is the use of longitudinal bracing rods beneath the bottom chord bracing the deck beams.

(A) Finite element mesh 4 (approximately 41,000 nodes, 230,000 elements). The periotic bone is trimmed off, and the red markers at the top-right of the mesh indicate nodes with prescribed displacements (as dictated by the motion or the lack of the motion of the squamosal bone of the skull). (B) Close-up of the ossicular chain and the sigmoidal process in the foreground. The joints between the ossicles are shown in color: the annular ligament between the stapes and the oval window is yellow; the incudostapedial ligament is green, and a small portion of the malleoincudal ligament is blue (most of this ligament and the malleus are obscured by the sigmoidal process).
