There are two options here. Either the Contractor assesses the compensation event based upon a five day week and then sees/agrees the impact on planned Completion and thus Completion Date accordingly. If once the compensation event is implemented it is then possible to speed that up by working weekends then that would bring forward their planned Completion in advance of the Completion Date and create “terminal float” which is owned by the Contractor.
As described however, if it is known that the weekend working is possible and planned – then if this does not move planned Completion then there can be no movement in Completion Date (as Jon has stated). A Contractor is obliged to mitigate where ever possible (but not obliged to accelerate – and there is a fine line between the two as you can read in other questions in this forum!)
