If You have to submit the programme to a Consultant 99% will not accept to have constrain in early, late or mandatory start or finish in trhe activities as well as to constrain the total float or the free one. (Previous experience in EPC contracts).
One suggest check the logic between through the engineering, procurement, construction, commissioning and the hand over, if look like not links are missing it could also be
If You want to send me the schedule to give a look, there is no problem.
1. Arrange the activities in groups and set a milestone at the end of each group completion and set latest finish constraint to the milestone with the float you need.
(end activitity date + the float you require).
2. perform a global change by filtering activities total float above lets say 60 days and apply latest finish constraints to those activities then all these activities will only have maximum total float of 60.
Anil I would suggest that what is embarrasing is the displaying of these float values in reports etc .
I suggest you do not display float to anyone on a general basis . It is important that the float is known by the managers to allow them to be aware of adverse trends.
In addition you may need to level the procurement activities to establish a more realistic schedule which will reduce the float available .
It is quite common to have high float values available for some Engineering and Procurement activities as long as you are monitoring ROS dates with FIS dates then can demonstrate that you are in control of the schedule.
“More activities to use up the float?” This is not a science fiction book that you are writing. It either takes time or it does not. The float is what it is. In reality, things take exactly as long as they do. You do not go looking for some way to use up the float. Leave the fiction for your expense account report.
If you hire a Consultant to work for you as an Inspector, you may end up submitting things to him or her. I imagine that this is similar. Once hired, us Consultants are hard to ignore.
There are no guidelines for maximum Total Float because Total Float is a product of the logical analysis, not an input.
Every submittal in your schedule should be followed by a review period (duration as specified in your specifications,) followed by a procurement / manufacture / delivery time (if the item is not available off-the-shelf locally.) Finally, this procurement (or the review activity if no procurement is necessary) should logically tie into the schedule where the item is to be installed or the procedure is to be used.
Run the CPM and the Total Float is what it is. No crying about the result if you agree on the inputs. Good luck!
Well said Ronald , you are absolutely right in contractual terms But dear i dont want to enter into conflicts at this stage of project. He has already rejected my submittal twice and now i have to satisfy him without risking our companies interest...Can you suggest some means to reslove this issue.

Create Radically Better Construction Schedules with ALICE Technologies
Use the power of AI to create construction schedules that reduce risk while cutting costs and build time. With ALICE, develop the ideal schedule during preconstruction -- or recover projects that are off schedule and over budget.

Alternatively, if youre using Primavera, set a Float Constraint under the Constraints section for the last activity.
However, I agree with the other posts - this is manipulating the logic. Get into a dispute and consultants will tear this apart.
Hi Anil,
There are two ways of doing it,
1. Arrange the activities in groups and set a milestone at the end of each group completion and set latest finish constraint to the milestone with the float you need.
(end activitity date + the float you require).
2. perform a global change by filtering activities total float above lets say 60 days and apply latest finish constraints to those activities then all these activities will only have maximum total float of 60.
I hope your problem solved.
Thanks & regards
Dinesh
Pay attention, if You are running a multi calendar programme, the critical activities can seat not on the critical path but on the longest one.

I prefer induce more activities to fill up the float. Like prepare order, place order, manufacturing, delivery, logistic arrangement, etc.
More detail, less float and form base for monitoring.

There is something very special about Consultants that you seemed to have overlooked; you do not work for them, they work for you. Ignore him.
