Could you elaborate on this for me? I have not used 4D planning tools before but I guess you are referring to Asta BIM? I thought this simply tied CAD type drawings to a regular schedule tool? In which case I don't see how having the 4D models would take away the need for durations, logic, a critical path etc?
If this is not the case, could you tell me how it works?
Thanks

If the programmer is not using CPM or constraints there is not real assurance that the project will be completed in time. That is the whole point of CPM its about logic durations and forecasting to a know end point.
Sure you can look at cash flow but the only thing that ties anything across a time elemet is the activities contained in the schedule. The more detail you have in the schedule the better you will be able to budget the costs over time.

I don't think so...how do u make a claim if no calculation made thru time and cost? to assist the claim is justifiable in terms of time this should be ensured that the project completion date is affected...of course if the activity is in the critical path.
Again, resourcing in schedule is also significant specifically if you know how it works with your resource requirement and how will you validate the cost of your schedule.
I think the issue nowadays is project controls is being manipulated from the financial perspective and not from a planning perspective. Sometimes earned value management is ignored. Anyway, that is only my opinion.

Two thoughts.
First see: http://mosaicprojects.wordpress.com/2016/11/26/the-future-of-project-controls/ to understand the problem
Then, if you are a PMI member sign up for their virtual conference on the 29th March to listen to my update on the blog-post - my session starts at around 3:40pm EDT: https://mosaicprojects.wordpress.com/2017/02/28/free-exclusive-project-scheduling-virtual-event-for-pmi-members/
If you are not a PMI member - go to the blog after the 29th for an update.
