this all depends on the real world logic lets take an example of a concrete footing installation

A=excavation

B= form

C= rebar 

D= pour

now there is a change which is is A+

is it a change to the excavation ?

is it a change the forming ? 

is it a change to the rebar ?

is it a change to the pouring ?

this will determine where A+ should be inserted and will determine the predcessor and successor

Abbas,

Normal practice is to make a baseline that preserves the original schedule.

Extra work can be either:

because of a poor estimate, which you only find out about when an activity starts, in which case a remaining duration update will push the activity’s finish out to the appropriate time, The baseline always shows what should have happened. Quite normal to have original duration 20 , started last week, remaining duration 25.

Because scope has been missed. You add activities exactly as normal, whose relationships are not dictated in any way by the fact that this is extra work. These activities might be in a ‘growth’ section of the WBS, or even in a separate ‘growth’ project linked to the base scope project. Once again the baseline tells us what should have happened
