B- how to avoid negative float: we have to commit that dates constrains are fact on the construction projects, however the method of applying these constrains may cause a confusion to the project schedule if we used the imposing tasks to must finish / start by and no later than in primavera..

Negative float, also known as negative slack, is the amount of time beyond a project�s scheduled completion that a task within the project requires. total float is the amount of time a task within a project can be delayed without endangering the project deadline.. The longest path will still be the critical path, but the total float values may be positive or negative values. again, the next continual sequence of work activities with a total float value close to that of the activities on the critical path should be the near critical path, based on total float values only.. Re-planning should immediately be performed to compress the schedule and get rid of the negative float, or your plan should be re-baselined, always with the customer's/sponsor's approval, to change the committed completion date..
