The topsoil and existing extension were removed across the footprint of the development areas through mechanical excavation by the use of a 360� excavator equipped with a toothless bucket. Following this, the footing trenches were excavated by mechanical excavator and by hand. With the exception of the removal of the superstructure of the previous extension, all groundworks were conducted under constant archaeological observation. The monitored groundworks for the extension were devoid of archaeological finds, features or deposits.
