Florida Southern College John McAslan & Partners
The college buildings, designed by Frank Lloyd Wright, are linked by a network of covered walkways, known as esplanades. These are sheltered by an elegant stepped arrangement of cantilevered concrete roof slabs which extend 2.9m over them and spring from highly detailed concrete piers.
Over the years they have deteriorated;
the cantilevered slabs have deflected and some cracking has occurred. John McAslan & Partners has designed new esplanade canopies, in a form sympathetic to Wright's originals. These will replace an espanade constructed after Wright's death and extend the network to connect new campus buildings.
The new canopies, formed of aluminium, have a light and delicate profile.They match the height of the originals and the depth of their projection over the walkway. They comprise a series of columns, triangular on plan. Each supports a lower canopy which extends over the outer side of the walkway, and an upper canopy which extends 2.8m in the opposite direction to cover the walkway.The canopies are made of tapered honeycomb panels clad both sides with aluminium sheet.
The upper canopy is supported by a 400 x 400mm tapered T-shaped spar with an 80mm diameter CHS welded to the base to form the bottom flange, which is bolted to the column head through a fixing plate. The lower canopy is supported by a similar, shorter, spar.Both spars are clad with V-shaped aluminium panels.
Each column is an aluminium truss structure of two 80mm diameter CHS posts and a third 100mm diameter post, braced with aluminium angles which provide fixing positions for the aluminium cladding.
