Question
To ask the Scottish Executive how the (a) estimated capital value and (b) timescale of the Glasgow Airport Rail Link compares with the original project cost and timescale estimates.
Answer
The original cost and timescale of the Glasgow Airport Rail Link (GARL) project are set out in the following table:
Glasgow Airport Rail Link (GARL) Cost (All Figures in £ Million) and Schedule
| Date | Out turn Cost Range | Anticipated Final Cost | Timeframe for Delivery |
| March 2006 | 170 “ 210 | 187.5 | Q1/2010 |
As the Paisley Corridor re-signalling (PCR) project would have led to significant closures of GARL, the decision was taken to merge the projects and align the timescales. Following the combination of the GARL project with the PCR renewal project, (GARL/PCR), the last estimate of the combined project, at the point where the branch line element was cancelled, are set out in the following table:
Glasgow Airport Rail Link/Paisley Corridor Renewal (GARL/PCR) Cost (All Figures in £ Million) and Schedule
| Date | Out turn Cost Range | Anticipated Final Cost | Timeframe for Delivery |
| September 2009 | 386 “ 408 | 397.5 | Q3/2013 |
March 2006 was the first time that the project cost had been expressed in out turn figures previously having been expressed in Q4/2004 prices (£160 million Q4/2004 equating to £170 million to £210 million Q1/2010 out turn). The out turn cost includes an assessment of the likely impact of cost indexation within the rail / construction industry over the lifecycle of the projects delivery.
