3.11 Figure 9 shows the key cost items, their percentage of the should cost model, the benchmark used, and the rationale.
3.12 The Department could not benchmark three cost elements of the services it had specified. Security, insurance and mobilisation, accounting for 14 per cent of total costs, were not benchmarked but were nevertheless reviewed to ensure that Land Securities Trillium's pricing approach was reasonable. The security requirements for Jobcentre Plus included a number of elements, in particular, a customer care role, which goes beyond a typical security specification in either an office or retail environment. The Department could not, therefore, benchmark Land Securities Trillium's security pricing against any external benchmark or to the original PRIME bid.
