A ‘linear sculpture’ fabricated in Grd 316 stainless steel and consisting of approximately 200 vertical members all supporting triangular, faceted panels which may interconnect in some instances.The entire sculpture to be assembled in Johannesburg and then dis-assembled and packed for shipping to Oregon USA.
Being able to interpret one mans abstract vision into a physical entity is a skill few people would possess.So, begun an intense series of planning meetings, idea swopping, mock up builds and lot of trial and error.Once again technology played an important key role as ideas became drawings and concepts began to take physical shapes. A strong partnership between the design team and the fabricator very quickly saw practicalities being introduced to the various mock ups and the individual shapes started to become recognizable as multi-dimensional sculpture began to form.
Several weeks of extremely detailed planning coupled with many hours of highly intricate detail drawing saw over 400 completed parts arriving at the fabrication shop. Each part an individual shape or cut and all carefully numbered were subjected to an intense polishing process before being set out in carefully prioritized sequences ready for assembly.
Each assembled component was certified by a member of the design team as he checked every angle, position and assembly order, before once again being processed through the polishing systems. The base, in total over 20mts long, was constructed in 8 individual sections consisting of 2 lasers cut 5mm plates separated by 150mm spacers, and fitted with tubular sleeves at specific angles, which would support the vertical members. The base sections were bolted together to from a waving ‘snake like’ platform which would be positioned into a water feature at the site.
The 180 vertical members are Ø38 tubular sections each with uniquely laser cut slots to accept the faceted plates. Each of the 300-laser cut 3mm plates were uniquely shaped and precision bent at various positions and welded into slots on the vertical posts.The vertical members are then slot guided into the sleeves in the base unit and the faceted plates form a multi- dimensional figure of a runner, which morphs into another figure as one moves along the length of the structure.
The components, after a final touch up polish, were wrapped in bubble wrap and carefully tied down into timber crates, with great care being taken to avoid the possibility of chaffing on a long sea journey.
Intricate packaging lists were compiled indicating every position of each component in the crate, which would assist when unpacking in Oregon. Crates were sealed at the fabrication shop before travelling by road to Durban, by sea to New York and then by train to Oregon before a final road trip to the site, Nike’s new World Head Office. Spiral Engineering’s commitment to quality and professionalism have once again been recognized and we are honored to have been appointed as a partner on this prestigious International project.
