Date lodged: 8 June 2016
To ask the Scottish Government on what dates adverse weather conditions have affected construction on the Forth replacement crossing.
Answered by: Keith Brown 15 June 2016
Adverse weather affects construction activities in different ways ranging from the need to alter a method of work to completely cancelling a piece of work. Consequently, it is not possible to list every date where adverse weather conditions have affected the construction on the Forth Replacement Crossing. However, the contractor estimates that approximately 20% of the project programme has been impacted.
Referring to my statement on 8 June 2016, the dates on which adverse weather conditions affecting construction during April and May 2016 are the dates on which wind gusts exceeded the threshold to allow critical path activities to take place. These are as follows:
April reporting period:
26 and 27 March (2 days)
28 March (0.5 days)
4, 6, 11, 12, 17, 18, 24, 25 and 29 (9 days)
1, 5 and 26 April (3 x 0.5 days)
April Report Total = 13 days
May reporting period:
2, 3, 7, 8, 9, 10, 11, 12 and 20 (9 days)
May report total = 12 days
The contractor’s reporting period cuts off on the last Friday of the month and so for the April reporting period the 13 days lost were in the period 26 March to 29 April and the 12 days in May were lost in the period 30 April to 27 May 2016.
