  Contract Changes 
  - When the project work is undertaken using one or more contractors, any changes in the work of any contract are changes for the contractor  - Because they change the scope of that contractor's contract. 
 
- This may include changes in timing if different from that contemplated at the time of contract agreement 
- From Project management's perspective, however, such changes may be either Scope Changes or Design Changes (see above)  - And must be processed accordingly
