The Procuring Authority and the Project Company are both primarily based in London, which has enabled a collaborative relationship through face to face interactions. This was done consciously by both the Procuring Authority and the Project Company, helped by the fact that their concerns are often aligned. This collaboration and alignment of concerns helps to avoid an adversarial relationship between the two parties. The parties have not, however, co-located, which the Procuring Authority sees as positive due to the necessary degree of separation it provides.
