Architecturally Exposed Structural Steelwork forms an important part of the design and construction process for buildings. There exists a great neeed for improvement in the communication between architect, engineer and fabricator in this area. AESS has significantly higher requirements for the form, fit and finish for fabrication, erection and coatings than regular structural steel so these must be taken into account throughout the development process. Structural engineers therefore become part of a triangle of communication in their documentation with the architect and the fabricator, especially affecting the way they design connections and their cost. This interactive design process is very different from the more linear process associated with ‘standard’ structural steel that is hidden from view and where the architect often steps back from detailed involvement. This Sample Specification (for Engineers) completes the Architecturally Exposed Structural Steelwork set of publications which also includes the Code of Practice (for Fabricators) and the Australia/New Zealand guide for specifying architecturally exposed structural steel which is available for purchase from the ASI Bookshop.
