Projects in this category include non-prestressed structures such as domes and shells made from more traditional materials like concrete.

Prestressed structures may include saddle shaped cablenets, planar wall or roof glass surfaces supported by a stressed cable network.

Externally supported roofs (cable supported) also come into this category. Articles are in random order.

Pitt Street Mall Catenary 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.

50 Martin Place - Glass Roof
50 Martin Place - Glass Roof

 

This Project was entered into the 2016 LSAA Design Awards (5047)

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.

Description: 

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.

Enclosure for Sumatran Tigers
Enclosure for Sumatran Tigers Project (2018)

 

Application: Zoo Enclosure for Sumatran Tigers.

This project was entered in the LSAA 2018 Design Awards (Cablenets, 4100)

PROJECT DESCRIPTION:

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.

Entered in the LSAA 2009 Design Awards (1099)

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.

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.

Wintergarden Art Façade
Wintergarden Art Façade Award of Excellence

LSAA 2013 Design Award of Excellence

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.

APPLICATION OF PROJECT:      
Playground Shade Structures 

PROJECT DESCRIPTION:

Situated in East Perth, Wellington Square is one of the largest parks within the City of Perth and the star attraction is certainly the 3000m2 intergenerational playground Koolangka Koolangka Waabiny, one of the biggest playgrounds in greater Perth consisting of nature play, a skate park, parkour activities, a flying fox, embankment slides, a pump track, waterplay and climbing towers, as well as basketball courts.  Large areas of the playground are covered by 3 large bespoke shade structures.

These shade structures consist of cantilever steelwork posts (by others) supporting complex hypar shaped sails constructed from Carl Stahl X-Tend Mesh with Ronstan cable borders. Decorative aluminium and perspex discs attached to the mesh with bespoke Ronstan clips to provide the shading effect.

Taronga Zoo Chimpanzee Enclosure
Taronga Zoo Chimpanzee Enclosure

 

LSAA 2011 Design Award Entry (Cat 2, 2019)

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.
