I've got a situation where I'm planning a job running two crews on a 10 on, 4 off roster (days). This means that over a two week period, there are three days where I have both crews working. I am trying to utilise them as a single resource to allow for leveling as either crew can perform the task. If I operate them as separate resources with different calendars, tasks are put off till the resource comes back (even though the other crew can do it).
Is there a way I can allow over allocation of a resource for a three day period (reoccurring over the life of the project)? If possible, is there a way to ensure that allowing over allocation to be for concurrent tasks? putting both crews on a single task would not yield any increase in efficiency.
I'm assuming this can be done and my skills are not up to the task so if anyone can walk me through it, that would be great.
