The Macarthur Wind Farm has the capacity to generate enough clean, green energy to power the equivalent of approximately 220,000 average Victorian households and also save approximately 1.5 million tons of greenhouse gases each year.
Although the original design consisted of N24 bar at 140mm each way for shrinkage control, cracking was a major concern. Thus Leighton Constructions turned to Helix Steel to three dimensionally reinforce 140 base structures and provide unparalleled pre-crack capabilities.
