If you are using construction scheduling software likewise primavera, MS Project or FastTrack Schedule. You face negative float during scheduling. you will commit that the fact activities with constrained dates affecting on the construction project planning process, however, the method of applying these constraints may cause confusion to the project schedule if we used the imposing tasks to must finish/start by and no later than in baseline project plan.
In terms of constraint in Primavera, it creates the negative float. However before we attempt to make any adjustment to Lags in the schedule, the appropriate suggestion would be that you should recheck all activities & observe why there is a need for it. There might be a reason why it is being used. If the only reason for using Lags is to suppress float, thus making the activity critical, then lags should be removed and it must show the real logic in the schedule.
Remember that:
1) Imperative linking of activities causes artificial negative floats in the schedule if activities are FS (Finish To Start) linked to each other will tend to push the project finish date to an else finish date.
2) The Project Setting "Must Finish By", should be checked if there's a date outpaced.
