In April 2011, Outside Ideas was awarded the Adelaide Airport Landside Infrastructure Project - its largest project at the time.

The main feature of the project is the 13,500 square metre plaza with granite pavers laid in mortar. During the peak of work, the Outside Ideas team was laying over 300 square metres a day. The centre of the plaza has a complex design featuring swirls of shot blasted concrete in two different colours. This detail required strategic pour dates to allow for the two stage pours per construction bay.

Another key component of the plaza is the system of 125 terrorist proof bollards, which were the first to be installed in South Australia, and had a tolerance on installation of 0.5 of a millimetre.

The scope also included planting 100,000 mature stock plants and trees, using over 7,500 tonnes of Jeffries Special Soil with 6,500 kilograms of TerraCottem mixed in; removing over 3,000 tonnes of contaminated soil, as well as earthworks and irrigation that integrated with the airport's existing 95 valve system.

The project was completed on time with a very pleased client.
