Hi Ben



Switch off the resource modelling aspect of the software.



Then the allocated hours will spread over the whole period.



Alertanively there are two sides to duration generation - Hours and Gang size.



The 114d duration can be maintained if you reduce the gang allocation pro rata.



This may result in less than 1 resource allocation.



The best result however is to accept that the 114 day duration has been overestimated and let it stay at 25 days.



If this affects the critical path then you can put in a time risk buffer to fill the gap.



Better still an activity of 114 days is too long anyway so break it up into maneable chunks - no more than 20 days - and resource each section.



Best regards

Cheers everyone,



The reason why the resource budgeted hours was driving the Activity duration was because the Duration Type was set to Time/Units, where it should have been Fixed Duration & Units, this prevents the duration changing when you edit the resouce manhours.



Thanks for all your help!



Thanks Trevor I recieved your message late, but I appreciate your help!!
