S5W-07593: Mike Rumbles (North East Scotland)

Scottish Liberal Democrats

Date lodged: 28 February 2017

To ask the Scottish Government whether it will provide an update on what the total cost of the Forth Replacement Crossing will be and how this compares with each of its previously published estimates, and what impact (a) the inflation rate has and (b) other factors have had on these figures.

Answered by: Keith Brown 9 March 2017

The total estimated cost of the Forth Replacement Crossing is £1.325 - £1.35 billion, £245 million lower than the June 2011 estimate when construction began. The inflation element of the £245 million saving is £192 million. The remaining saving of £53 million is a reduction in the allowance for risk and optimism bias which have steadily decreased as the project has progressed through robust risk and project management. These savings are in addition to those achieved through the contract procurement process in 2010 which reduced the median project forecast by £512 million and the near halving of the initial £3.2 to £4.2 billion project estimate by incorporating the Forth Road Bridge and other existing infrastructure in the overall project scope.
