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.

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.

Entrant: Aurecon - Adelaide - Designer / Consultant
Location: Adelaide Botanical Gardens - North Terrace Adelaide SA
A new glasshouse was required to replace the dilapidated Victoria House, in a very sensitive location in the centre of Adelaide’s Botanic Gardens. The heritage-listed 1867 Lily Pond in the Victoria House had to be preserved and the design was not to detract from the adjacent heritage-listed buildings. Glass was chosen as the main structural material as the designers wanted a solution that would not detract from the surrounding heritage buildings, but that would still provide a modern, minimalist and elegant centrepiece for the Gardens’ future.

Entrant: Taylor Thomson Whitting (Engineer)
Location: 50 Martin Place, Sydney. Completed: Unknown Client: Macquarie
Team: Johnson Pilton Walker, Taylor Thomson Whitting, Brookfield Multiplex, Sharvain Pacific Steel
Application: Glazed Roof over an Atrium.
50 Martin Place was refurbished to provide a communal office from a very important heritage building. To increase light into the Atrium, the Atrium was increased in size by removing the perimeter slab, leaving the beams and columns. To provide maximum light, the roof was fabricated from glass. The final design incorporated a dome on steel trapezoid section suspending triple layer glazed panels, some of which were adjustable.

Wintergarden Art Façade: Judges Comments
"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.
Pitt Street Lighting System
The City of Sydney turned to Ronstan to upgrade Pitt Street Mall's lighting to an energy-efficient catenary system as part of the overall redevelopment at the precinct. The result is a ladder-like series of lights supported by a Ronstan high-tension stainless steel cable framework.
The system illuminates the pedestrian areas below and the facades of the buildings, without needing large self-standing poles or heavy-looking supports. The 16m high tensile cable web is almost invisible, with bowstring support cables anchored every 20 meters into the facades of the buildings along the mall.
The catenary lights themselves comprise long tubes, combining downward illumination and a sequence of LEDs along the vertical length, which can be programmed for different colors depending on seasonal requirements – reflecting specific moods and occasions.

Perth Zoo Wetlands & Penguin Enclosure
PROJECT APPLICATION AND DESCRIPTION: Zoological Enclosure
Structural Dynamics was contracted by The Slatter Group WA to assist with the design, material selection/supply and installation of a lightweight zoological enclosure that would cover an area of 90 meters long, 34 meters wide and 10 meters high.
The enclosure was covering two existing exhibits at the Perth Zoo, namely the penguin display and wetlands area, so needed to have minimal impact on the existing flora and infrastructure.
Pritchard Francis had already conducted the majority of the structural design and calculations of loads - Structural Dynamics assisted both The Slatter Group WA and Pritchard Francis with final material specifications to meet demanding requirements.

The implementation of form and function. Creation of shade function with a sculptural form
Cable Net Facade Feature - New Entrance
The redevelopment of Whitten Oval formed a pivotal piece in a plan to reinvigorate the western suburbs of Melbourne by providing services and facilities that would promote a sense of community. The plan had involvement from both State and Federal Governments and sort to place Whitten Oval at the centre of the community as a hub for local sporting and health service activities.
The Whitten Stand conversion, designed by Peddle Thorp Architects in Melbourne, called for a feature on the façade that responded to its context, was an identifiable entry, and provided an environmental benefit in the form of shading for the glazed façade behind. The resulting design was a series of floating panels that would display the team colours of the grounds home AFL team, the Western Bulldogs. The façade feature would run from the first floor to the roof acting as a gateway for supporters.

Category 5 "Glazing and Facades"
Application: Zoo Enclosure for Sumatran Tigers.
This project was entered in the LSAA 2018 Design Awards (Cablenets, 4100)
The Sumatran Tiger Enclosure at Taronga Zoo consists of three separate enclosures.
Enclosure 1 and 3 are free form tensile roof canopies constructed from X-Tend Mesh. X-Tend Mesh effectively acts as a tensioned cable net structure.
The mesh is tied to catenary cable boundaries connected to masts with tieback cables and is pushed / pulled up with 4 flying masts in each enclosure. The flying masts are supported on a structural cable net that is attached to a large central mast and tied back to the perimeter masts structures.

Entrant: Ronstan – Contractors
Location: Barkley St, Footscray Vic Client: Western Bulldogs, Whitten Oval
Architect: Peddle Thorp Struct. Eng.: Irwin Consultants
Builder: Salta Fabricator: Ronstan
Design Brief: The Architect called for a transparent screening element that would act as a billboard for the oval as well as the local community. It needed to be light enough that it did not detract from the facade but provided adequate passive solar protection to enhance the sustainability of the building.
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.
