This photograph shows the arrangement for storing the tiles. On the right is the 'storage container' (a converted shipping container). There are three tiles resting against it (the spare tile, and two new ones).
The Lehtinen Barracks stands higher and can be seen behind the stored tiles (although they are not resting on it per se). The barracks are also used as a resting point for tiles and tile lids. In the left background, there is a partially unloaded lorry and further back (behind the trees on the main road), there is another lorry waiting to come on to the site.
