Overview of project 

Narranderra Shire Council contracted Struktis Steel to manufacture and install a skywalk, set to become the key vantage point of Lake Talbot, a well-known local attraction. The project specified the need for a 50m long structure, elevated 17m above the water level, with minimal impact on the surrounding environment being a key priority.  

Business Challenge 

The most significant challenge throughout the project was the negative response it garnered from local community groups. Locals felt strongly that the skywalk would interfere with the surrounding environment, and would detract from the popularity of the local attraction, rather than adding value to it. Since the skywalk needed to be installed on the banks of the river, comprehensive soil testing was essential to ensure that the correct footings and foundations were used. It was crucial that the skywalk made as little impact on the surrounding area as possible. A unique approach to fabrication and installation would be essential to minimise the project’s commercial footprint. 

Solution 

Struktis undertook comprehensive geotech testing and land surveying before commencing fabrication, ensuring all requirements were not only met but exceeded. The skywalk spans 50 metres in length and was constructed using a tubular steel system with composite plastic decking. Struktis devised an alternative solution for the pile system, which enhanced the efficiency of the skywalk structure. 

Throughout the fabrication process, stakeholders were kept informed via photographic progress updates. “We had a very open and transparent working relationship with Struktis throughout the project”, Mr Wilson said. 

The project was executed in three stages. Prioritising the pier and headstock in stage one, erecting the main column and filling cauls with concrete in stage two, and installing the crane loop in stage three. Struktis really became a part of the project, they were way more than just a contractor”, Mr Wilson adds, “There were absolutely no areas of defect or concern throughout the entire project.”

Numerous community meetings were held to garner local support, while the local council’s endorsement of the concept played a crucial role in gaining community acceptance. “Once the skywalk had been built, people could see for themselves how much it adds to the space”, said Mr Wilson.
