In the perfect world contracts would be clear and readily comprehensible. They would not lead to disputes and the parties would not require third party assistance to determine those disputes. We do not live in a perfect world.
This paper addresses the separate but linked issues of change, how is it valued valuations and the selection of the Tribunal to determine those disputes where the change or its value or both is put in issue by the parties.
To illustrate this, the author considers and compares the ICE 7th Edition contract and the FIDIC Red Book. This therefore gives scope for consideration ranging from a primarily domestic engineering contract to a contract frequently used for large international projects. Similarly as FIDIC is historically derived from the ICE forms, it is founded in common law jurisdiction and even those have not come across it in detail, will be familiar with the form of its provisions, its style and intent.
