I am trying to calculate delay to a project - there is nothing contractually written that states anything to do with extensions of time within the contract, however, the client and contractor both agreed to re-baseline the schedule when delay started to occur. This occured several times with four revised baselines agreed between both parties - therefore my question is this:
When using an as planned versus as built schedule, do i use the original schedule or the last agreed baseline? As surely no delay occurs if i accept the last baseline if delay occured before that revised schedule?
Any help or input would be greatly appreciated.
