Pryda fabricator, Sunbury Wall Frames and Trusses knew the enormous roof trusses it was designing and manufacturing for the Bellarine Lakes Country Club Villageâ€™s large community centre would be a daunting task to erect.
So managing director Danny Schneider organised to have Prydaâ€™s engineers armed with the Pryda Build design software to be on site so the supervisor and carpenters could see a computerised 3-D visualisation of the project once it was fully assembled.
â€œThis gave the carpenters a better understanding of how to read the installation documentation, so they were more comfortable with the assembly process,â€ he said.
The community centre roof span is almost 32 metres â€“ supported in the centre by a steel i-beam to which the 582 prefabricated trusses (the longest of which is 17.34 metres) have been attached.
The 1300 square-metre building, supporting glazed terracotta roof tiles that weigh 180 tonnes and an air-conditioning unit, is the focal point for the village. When designing the roof truss structure, Sunbury Wall Frames and Trusses use the Pryda Build software. One of the great advantages of Pryda Build is that the design component takes into account loads caused by the likes of heavy tile roofs, air-conditioning units and local wind conditions.
Bellarine Lakes Country Club Village has been developed to accommodate retirees and near retirement â€œempty nestersâ€. The village is constructed on a former eighteen-hole golf course. Nine holes have been allocated to the $60-$70 million development with the remaining nine holes, a bowling green and the community centre part of the available facilities for residents.
Begun in 2013, when finished in 2018 the 48-hectare project (70 per cent of which is the golf course) will contain 350 dwellings including 265 two and three-bedroom fully detached villas with single and double garages with tilt garage door openers maintaining them, 45 one and two-bedroom apartments over two storeys and 28 condominiums.
Bellarine Lakes Country Club Villageâ€™s senior project manager Anthony Singleton said the community centre was designed with a four-hip roof to fit in with the aesthetics of the overall project and to look like a country club golf course facility.
â€œCost was the major factor in deciding to use prefabricated timber roof trusses,â€ he said.
Stephen Allen, project manager for the builder A.W. Nicholson, said given the complexity of the community centre roof, any last minute changes to the structure were easier to accommodate in timber than steel.
â€œIn this type of application, we prefer working in timber, trusses are easier and quicker to accommodate change and, being a renewable resource, timber is more environmentally friendly,â€ he said.
The highest point for the truss roof is 13 metres, more than four times the height of the three-metre prefabricated concrete tilt panels supporting it. The truss roof is in two layers â€“ the bottom section comprising flatbeds with another section on top â€“ and all the trusses were erected within 18 days. This complex roof design was easily handled with Pryda Build software in combination with experienced Sunbury Frame and Truss detailer, Brendan Schneider.
Danny Schneider said Sunbury Wall Frames and Trusses was one of the few fabricating plants prepared to tackle large commercial projects.
â€œOne of the reasons is our sophisticated in house engineering capability where many other truss plants are having their estimating and design work carried out offshore,â€ he said.
â€œThis might be all right for domestic dwellings with simple truss construction but is not good for complex design work like that seen in the Bellarine Lakes Country Club Villageâ€™s community centre.â€
Sunbury Wall Frames and Trusses uses timber imported from Europe, Canada and the United States because the company feels that their products better reflect the requirements for this application.
