3.2 The Department appointed its advisers in good time: three by competition, and one jointly appointed with Land Securities Trillium in competition. The Department used its existing property and legal advisers, though with some re-negotiation of rates. The cost of advice shown in Figure 8 was £9.6 million, which exceeded the budget by £2.2 million. The budget was set prior to the full scope of the project being determined and extra work was needed on data certification and due diligence work. Another driver of the increased cost, however, was Land Securities Trillium's approach to its initial bid, which the Department did not regard as a suitable basis on which to commence negotiations. An extension of the bidding period was therefore required to secure better value for money.
