On Chelsea Barracks Building 6, you mentioned the Contractor was in delay and you reassessed the value of prelims. What are the two methods of doing this?
1) You take away the number of weeks delay from the amount complete. Ie, if 50 weeks had gone by in a 100 week programme, if the Contractor is 10 weeks late you would take the 10 weeks from the 50. So (50-10)/100.
2) You add on the number of weeks delay to the overall contract period. Ie, same example as above, 50/(100+10).
How did you reassess the Contractor’s delay on Chelsea Barracks Building 6?
I added on the number of weeks delay onto the total period of time. Ie, the Contractor was reporting a delay of 5 weeks so I added this on to the overall period length.
