and its surrounding area,” Brown recounts. Some of the columns were given piggyback heads for pedestrian and cycle lanes and, crucially, Philips Cosmopolis lamps were used to improve colour rendering and enhance the perceived sense of safety for users. Fittings use a flat glass to ensure no light is projected above the horizontal plane.
“The installed effect is of a much cleaner lit environment with columns that create a visual rhythm during the day without over- whelming the streetscape,” says Brown.
THE SHOAL A key element of the project was the in- troduction of a 250m long kinetic sculpture that runs along one side of the A11 gyratory. Dubbed the ‘Shoal’, the piece presents a fresh, dynamic face to the Stratford trans-
port hub and the Olympic park. It is con- structed from a tubular steel framework, designed to represent the trunks of trees, on to which large lozenge-shaped ‘leaves’ are hung. Each leaf follows one of three forms and is clad with titanium that has been anodised at different voltages to give the surface a range of colours, from blue to yellow. The leaves are arranged so that the colour gradually shifts along the length of the piece from one extreme to the other. Each leaf is held in place by a dampening shock absorber that allows some movement of the leaves in a strong wind, making the whole sculpture appear to shimmer during inclement weather.
The lighting brief for the Shoal was to pro- vide a non-uniform scattering of light across the leaves, using it to enhance their form and texture and express the colour and
The Shoal is supported by an avenue of trunk-like columns through which pedestrians can walk. As a consequence, the appearance of the leaves had to be considered from all angles. Early in the design process it was decided that incorporating fixtures within the sculpture would prove prohibitively expensive, so Rocca Maxi inground uplights from Aquila were used. This proved very effective in enhancing the colour and texture of the anodised leaves.
