John Holland Concrete Precast Plant Roof Cover

XXL CONSTRUCTIONS SMRT® hybrid connection design solution capably catered for this structure's whopping 34 metre clear-span, hill location, and the region's cyclonic conditions.

John Holland Builders needed a precast concrete facility to help them repair local central QLD infrastructure damaged after the floods. So they engaged XXL CONSTRUCTIONS to design and supply a roof cover to meet the requirements.

Within 7 weeks XXL CONSTRUCTIONS engineered, designed, and delivered all materials to site ready for erection. Using XXL CONSTRUCTIONS SMRT® hybrid connection solution the structure design competently caters for cyclonic conditions, a very high building, and a 34 metre clear span. The SMRT® hybrid connection design solution allowed strong and rigid steel hot-rolled columns to transition efficiently and effectively to the cold form steel rafters of this massive portal frame. Utilising the SMRT® hybrid connection design solution assured the engineering brief was met for the span required and importantly enabled massive materials cost savings.

John Holland were ecstatic with the structure providing them with a purpose designed protected space to meet their needs and with the cost savings. Being able to take advantage of the enormous benefits of the patented SMRT® hybrid design connection solution brought the structure 35% under budget. Soon after construction was completed, the structure was put to the test with category 5 Cyclone Marcia passing straight through the region leaving the XXL CONSTRUCTIONS designed structure standing securely and proudly atop the hill it’s built on.
