Samaras Structural Engineers which included six 35-tonne primary trusses cantilevering from the rear of the grandstand, supported by roof columns that were cut into the upper bowl. According to Chris, that roof structure has spans of up to 55 metres, while only weighing roughly 432 tonnes. As such, itrecognised as “one of the lightest roof forms in Australia for such spans.” “Design workshops were conducted to develop and finalise the final steel roof design,and the final design and documentation,” Chris recalls.“Early design development involvement with the design team, engineers, architects, and the client also enabled us to provide crucial input and 3D Modelling to ensure the final design was constructible and met client objectives.” Chris explains that trial assemblies of the Diagrid Roof Structure were conducted at the company’spurpose-built site at Gillman prior to installation onsite, ensuring risk-free perfect alignment of the roof structure during the onsite activities. “That was themost critical part of the job,” Chris explains. “We have such a big yard, so once we fabricated the materials – and just before we painted them – we assembled the entire roof in yard. So we knew that when it got to site, every bolt and every piece of steel would fit like a jigsaw puzzle. And if any issues did arise, we could iron them out before they hit the construction site. That was a huge critical advantage. The customer was very satisfied with that.” According to Chris, Samaras Structural Engineers wanted to be part of the Adelaide Oval project as soon as it was announced,
