City of Sydney has upgraded the Pitt Street Mall lighting to an energy-efficient catenary system as part of the overall redevelopment works at the precinct.

Project Background

City of Sydney has upgraded the Pitt Street Mall lighting to an energy-efficient catenary system as part of the overall redevelopment works at the precinct. The result is a ladder-like series of lights supported by a high tension stainless steel cable framework manufactured and installed by Ronstan Tensile Architecture.

This catenary lighting 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 20m into the facades of the buildings along the mall.

The catenary lights themselves comprise long tubes, combining the downwards illumination and a sequence of LEDS along the vertical length, which can be programmed for different colours depending on seasonal requirements.

Key Facts at a Glance

    • The lighting systems extends for 180 metres down the centre of Pitt Street Mall, Sydney
    • It provides illumination to the required standard of 4 Lux in the vertical, lights can be programmed to reflect different moods and occasions
    • It comprises a twin longitudinal cable arrangement tied back to the surrounding buildings via spacers and guying cables
    • 23 customised tube style luminaires (lights) are suspended between the twin cable ‘ribbon’
    • 34 Marine Grade 316 stainless steel ribbon catenary cables were used, comprising a total length of approximately 575 metres
    • The cables are a 1×19 strand cable capable of withstanding up to 60 tonnes of tension, designed and manufactured to withstand corrosion and stretch
    • Some cable anchors tie to buildings set back approx 20m from the mall. The catenary lighting system needed to float clear of the fully glazed Westfield Pedestrian Bridge which it passes over
    • The majority of construction works needed to be carried out at night for reasons of public safety and minimising disruption to businesses fronting the Mall.
