Shanghai Disney Land Architectually Exposed Structural Steelworks AESS
On Sep.15,2014, Shanghai Disney Land Steel Structure AESS Mock-up Inspection and Approval by Disney Senior Authority from LAX,USA
Our scope of supply: Main Entry gates and gradens AESS Structure Fabrication and supply
Difficulty: Architectually Exposed Structural Steelworks
Even the project totally uses light steel structure and the tonnage is not so big, but the steel materials various a lot(around 100kinds), compare with past big project, the fabrication standard is far higher than normal domestic GB or international steel steel codes, all the surface of steelworks shall be grinded into perfect visual effect of AESS categories - AESS 3.
AESS 3 – Feature Elements includes structures that will be viewed at a distance ≤ 6m. The Category would be suitable for "feature" elements – where the designer is comfortable allowing the viewer to see the art of metalworking. The welds should be generally smooth but visible and some grind marks would be acceptable. Tolerances must be tighter than normal standards. As this structure is normally viewed closer than six meters it might also frequently be subject to touch by the public, therefore warranting a smoother and more uniform finish and appearance. This type of structure could be found in airports, shopping centres, hospitals or lobbies and could be expected to incur a moderate cost premium that could range from 60% to 150% over Standard Structural Steel as a function of the complexity and level of final finish desired.
When AESS structural elements are brought into close range for view as well as potentially for touch, it is necessary for the team to come to a clear understanding about the level of finish that is both required and expected of the steel. The natural look of welds that would be out of view in AESS 2 steel will now be visible to the occupant in the space. Simple bolted connections may need to be designed to look more artful if they are to become part of the language of the architecture. Connections will come under closer scrutiny, so their design, tolerances and uniform appearance will become more important and the workmanship required to improve these beyond both Standard Structural Steel and AESS 1 and 2 could have a significant impact on the cost of the overall structure. If the required attributes or characteristics of the steel are not thoughtfully considered, the AESS for the project can easily be priced higher.
