Calculating cost on minimum day rate item

In the Open Standard

Hi,

We have a scenario where a crane costs us say £1,500 per day (8hr day). Even if the crane is only used for 1hr, we still get charged for the whole day. if we go over 8hr a day then it's charged at £45 p/h.

I don't really know how to establish a payrate using these figures. £1,500/8=£174p/h so I cannot simply use that pricing per hour, and that wouldnt accomodate the minimum unit of 1 day @ £1,500.

I found a post here http://www.planningplanet.com/forums/microsoft-project/545518/how-specify-rate-day-regardless-hours-worked-day which suggested using a hammock task, but quite often the tasks where a crane would be required wouldn't be consecutive.

Any thoughts would be greatly appreciated.

    Hi Mike,

    It's a mobile crane that would be called off as and when needed.

    Hi HarryThe only way I can

    Hi Harry

    The only way I can suggest is to set up 8 crane resource setcions each with 1 to 8 cost hours attached and allocate accordingly to the relevant task.

    You then have the problem of delivery and collection costs at each deployment unles it is on unpaid standby when not in use.

    Best  regards

    Mike, calendars and partial

    Mike, calendars and partial workloads can complicate the calculations.  How would you model the cost of the crane for the following scenario?

    Crane sharing is very common.
