Which of the following scenarios has the potential to impact the project schedule? Question 2 options: Scenario 1: The owner makes the change before the design is completed. The cost is minimal (the difference in the door prices). Scenario 2: The owner makes the change after the design is completed but before the bidding begins. There may be a minor additional cost associated with the architect redoing some of the drawings and specifications. Scenario 3: The owner makes the change after signing the construction contract but before the doors are delivered and the work on that portion has started. The cost may still be minimal, but this has become a change order. The contractor may try to make some "extra profit." Scenario 4: The owner makes the change after the door openings have been framed (in masonry walls) but before the walls are finished. The change includes the cost of widening the door openings, that is, demolition of part of the masonry walls, and installing new door frames. If the doors have been delivered, there is an extra charge for delivery and restocking
