Other Structural Forms - Cablenets, Glazing, Facades, Spaceframes
The LSAA has groups of members interested in cablenets, high technology glazing and facades.
In fact one main reason for the creation of the LSAA from the MSAA was to cater for the growing number of projects which involved large glazed areas being supported by pretensioned cable truss systems or cablenets.
In modern times, when the overall energy usage for the life of a building is taken into account, the use of high technology facades will become more important. There is also a growing use of "green facades" or vertical gardens.
The traditional spaceframe structures are becoming rarer - those with many small elements that are man-handled and connected together on site. Labour costs and erection times are now outweighed by fewer larger assemblies that can be installed quickly by cranes.
The LSAA would welcome articles and links to projects in this category.

Overview of Cablenet Structures
The modern cablenet structures burst on the international scene with the Expo 67 German Pavilion constructed in Montreal, Canada.
This was a larger version of the cablenet roof prototype designed by Frei Otto's team and used now to house the IL at the University of Stuggart.
Australia can bost a very early cable net structure in the Sidney Myer Music Bowl in Melbourne.
The next structure, and the most famous is the impressive stadiums for the Munich Olympics designed by Frei Otto.
Highly stressed cable trusses are also used to support flat glass surfaces now common for facades.

Jagged Edge - Queenstown NZ
An Atypical design and Construct project involving a house for a confidential client. The design was prepared and presented as a “Design+Construct” package that was purchased as a package by the Client. The Builders Team had prepared preliminary documentation based on advice from specialist consultants and Architects. The design was then proposed for sale to the market as a complete delivery vehicle.
The project is a residential building built on the side of hill with an impressive vantage point. The main goal of the design is to maximise transparency to optimise the view.
The bedrock of the mountain is used for the foundation of the roof which is suspended projecting towards the lake. The project utilises tension cables and clamps to support the glass façade panels.

"Will probably settle in to become a heritage icon in Brisbane."
"Now that's how to disguise a carpark. Makes a great contribution to the public realm. Vivid, joyful - makes excellent use of contemporary steel design and fabrication technology."
APPLICATION OF PROJECT:
The vertical façade works is part of the redevelopment of the wintergarden shopping centre.. This façade creates a uniform streetscape, providing a visual barrier to a number of existing carparking levels and different buildings along Queen Street Mall.
Wintergarden redevelopment architectural façade on Queen, Elizabeth and Edward Street, Brisbane. The architectural intent of the façade is to create a three dimensional depiction of a winter garden painting To achieve this, the façade consists of multi layers of rigid cladding supported by a modular structural steel grillage frame. In addition to the cladding panels, the façade consists of a number of steel frame, stainless steel cald butterflies which cantilever from the grillage.

Taronga Zoo Chimpanzee Enclosure - Sydney
APPLICATION OF PROJECT: Separation Enclosure for Chimpanzees.
The Taronga Zoos’ chimpanzee troop is one of the largest captive groups in the world with recognized wild behavior patterns and a sophisticated social hierarchy. With its population including four maturing sub-adult males jockeying and promoting themselves within the group, the zoo cited a need for the construction of a fully enclosed and semi-transparent separation paddock within the chimpanzee exhibit to allow the chimpanzees to be easily divided as needed, without moving them to an entirely new location, and thus avoiding potential commotion.
The Seperation Enclosure:
- facilitates the introduction of new chimpanzee females to maintain the genetic pool.
- provides the necessary infrastructure for the current troop management strategy and philosophies.
- permits the troop to remain outside in summer unsupervised where this was previously not possible.
- maximizes viewing time for the public.

Ronstan Ribbons of Light
Ronstan Tensile Architecture provides full-service engineering, design assistance, and installation services for an innovative catenary lighting system that spirals through the Watergardens Town Centre in Taylor Lakes, Victoria.
Watergardens Town Centre is a 56 hectare community hub that offers shopping, dining, entertainment, hospitality, and other business services. The area has been a vibrant and growing part of Taylor Lakes township since its 1997 opening, attracting droves of visitors to its 200+ specialty stores and community events.
Recently, the Centre has expanded to include a dining-focused "eat street" called Station Streat, which is now outfitted with a custom Ronstan catenary lighting system. This system, designed by Electrolight and Ronstan, stylishly assists in making the area functional after dark without being obstructive to walking paths. More importantly, the system creates a spectacular entry statement with its unconventional 3-D "ribbon like" design that speaks to the geometric language of the Centre's existing graphic motif.
"The idea was to create a lighting scheme that gives a sense of movement and direction," explains Paul Beale, Director at Electrolight. "We endeavoured to create a visual link from the Centre's train station to the main entrance and shopping areas, while also highlighting the eddies of other parts in the complex that may have otherwise gone unnoticed."
