In the process of decision making between mutually exclusive projects any cost which is left due to selection of alternative project is called the opportunity cost. For Example: if a person select project a and have to loss 1000 due to selection of project a, or if person select project b and loss 2000 due to it then project a has an opportunity cost of 1000 while project b has 2000.
Project cost control is comparing the actual project cost against planned project cost.
The estimated padding requirements for this project are approximately 10 of the total budget to account for unexpected costs and contingencies.
