Further delay caused because panels are taking a lot longer to build than previously anticipated. Worksite is short of labour in regards to all the different activities that are taking place.
Additional Labour has now been requested and confirmed for the night shift so that panel building on phase two can progress at the same time as installation panels for plain line on phase 1. Programme will now be revised to reflect this delay with activities removed at the backend. 6
