The site is marked in the landscape by the co-ordinates of human commitment which distinguishes the emergency services. Co-ordinates are revealed as a pattern of broken lines in the landscape and which, when they intersect, form the memorial itself.The rhythm of the broken lines is based on the international morse code for distress - SOS - the earliest form of emergency telecommunications.Today the lines represent the importance of telecommunications for the emergency services network, either via satellite, wave or wire based systems.The crossing of the co-ordinate lines defines the memorial. The arrival and orientation area is behind three inclined concrete blades. Visitors can see the reflection space through slots in the blades, and read about the memorial and its purpose.Visitors can enter the 'confined' contemplation space by passing between the inclined 'blades of danger' and the 'fins of service'. The closeness requires heads to be bowed on passing into the space. This space is 'close' and personal and does not lend itself to large gatherings.
