Surface Ducting Channels from ACO Polycrete

It's Showtime for ACO's Surface Ducting System

For the first time in many years, the Royal Adelaide Showground underwent a significant redevelopment. Within its precincts, the Goyder and Jubilee Pavilions are home of the annual Glendi festival, an annual weekend long festival that celebrates Greek culture in Australia. The pavilions' upgrade and their adjoining areas were recently classified by the State Government of South Australia as having 'Major Project Status', as it would attract more visitors and patrons overtime to its major events. The Northern Plaza, in particular, was also rebuilt to cater for a growing volume of exhibitions scheduled for the future. It would also cater for the ever increasing number of show rides and entertainment stands at the annual Royal Show.

The design brief required that the pavement withstand unprecedented traffic loads during its design life as large mining and construction equipment would be required for exhibitions and large transportable show rides, during festivities. In addition, the area also required extensive power supply infrastructure to these facilities and ease of accessibility to cables for maintenance operations without compromise to security, safety of maintenance crews and the general public. Designers specified ACO's CS100 Ducting, a system of metre length modular surface ducting channels manufactured from durable polymer concrete. The channels are assembled in line to produce continuous runs and their profiled side walls provide structural rigidity and anchorage to the surrounding pavement.

The system's OH&S friendly ductile iron lids are load rated to Class G900 AS3996 and have anti-slip features. Each 500mm long section is secured to the channel by four high tensile steel bolts, incorporating friction grip washers to deter bolts from working loose during service. When lids are removed, specialised crews would then have uninterrupted access to the cables for ease of maintenance.
