Changes to contracts

Builder variations
Two examples of why a builder would request changes are given here:
Excavation
A builder is excavating for the foundation and finds an old septic tank underground where a major support structure needs to be placed. This tank was not shown on the original plans. The builder may wish to change the support structure or dig out the tank and carry on. In either case the builder would need to fill in a variation request as more time and money are needed.
Structure 
A builder is planning to put a door in an existing wall. The builder starts to demolish the wall only to find that the wall was part of a major support structure. The wall cannot be demolished without consultation with an engineer and an extra support member being installed. In adding the extra support member the height specified for the door will have to change. The builder would have to request a variation to change the size of the door and install the extra support structure.
