Projects from 2018 LSAA Design Awards - Category 5 Facades
Category 5 "Glazing and Facades"
5431 RNA Brisbane Large Animal Pavillion.
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.

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.
This project was entered in the 2013 LSAA Design Awards (#4966)
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.
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.
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.

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.
This project was an entry in the 2016 LSAA Design Awards (0481)
Entrant: Tensys Engineers Pty Ltd (Engineer)
Location: 155 Queen St Mall, Brisbane. Completed: 2015 Client: ISPT Super Property
Team: studio 505 / JWA, Tensys Engineers, Tensys (Façade), UAP Company, Broad Construction
Application
The implementation of form and function. Creation of shade function with a sculptural form
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.
