Each sign had a total length of 22 metres. Manufactured in two main sections with ten legs to stand each sign into position. The complete sign was manufactured and installed to engineer details. Over 750 metres of steel was cut and welded into place. Every piece of steel was galvanised and later painted onsite. The images were drum scanned from paintings prepared by a local Aboriginal Elder, then printed and laminated to ACM panels. Each leg was lifted into place at the varying angles, with the final main sections being lifted by the 100 ton crane.
With twenty concrete piers spread over a 170 square metre area the precision required during manufacturing the two signs was only half the challenge. Twenty individual legs standing in varying angles to each other meant the exact location of each footing was essential. Over 12 cubic metres of concrete was poured to hold the two signs in position. The use of a 100 ton crane was used to lift each leg into position then the final two 22 metre signs were bolted on top. The complete installation process from the hole piering and concrete pouring to the final erection of the sign was over a six week period.
