Forms of Contract

Contract disputes cost money, take valuable time to resolve and can damage good relations. However, they can be avoided by using the IChemE Forms of Contract. This two-day course will show you how to get the most out of those contracts.

The IChemE Forms of Contract are drafted as performance-based contracts for the design and construction of a process plant and other output-based projects. Specifically addressing the liabilities and testing regimes appropriate for a performance plant, they are used extensively across a range of process industries.

This course examines both the UK and international suites of contracts: their approach to risk and payment, their structure, how they govern work from initial requirements through design to fully commissioned and operational plant, and party liabilities.
