Forms of contract

IChemE Forms of Contract

IChemE publishes two sets of forms of contracts for use in the process industries:

  • forms for use in the UK
  • forms for international use

  • Both sets have been drafted by a team of highly experienced professionals who are well familiar with process plant contracts.

    Each form of contract handbook contains a model form of Agreement and General Conditions, together with detailed guide notes to assist the user in preparing a contract.

    IChemE provides both public and in-company training courses in the forms of contract, and in basic contract law.

    Contracts - UK and international

    Process plants are judged by their performance in operation. Process industry contracts must, therefore, also be performance based. This is the underlying philosophy of IChemE’s Forms of contract suite. It is a fundamental difference from much of the wider construction industry.

    IChemE's contracts are used extensively not only in the process industries, which themselves range from oil and gas to pharmaceuticals, food and fibres and many more, but also increasingly in a wide range of other industries both in the UK and internationally where their philosophy of fairness between the parties and teamwork in project execution are recognised as beneficial.

    Originally IChemE's contracts were drafted to operate under English law. Their growing international use has led to the preparation of a further suite of forms of contract written for international use under a wide range of legal systems.

    All the contracts are internally consistent and have extensive guide notes to help in their completion and operation. They reflect best practice in the process industries and recent developments in both law and project implementation.

    IChemE's contracts have been specifically written to reflect the particular needs of the process industries, and key features include:

  • multi disciplinary
  • technology based (purchaser, contractor or licensor’s technology)
  • close integration between design and construction
  • project success measured by extensive performance testing

    Training courses

    What every engineer should know about contracts

    12-13 May 2010, London, UK
    5-6 October 2010, London, UK

    Learn about the law of contract and why contracts say what they say
    When managing projects whether large or small, a clear understanding of the law of contract is essential. Failure to understand the basics can prove very expensive. This course has been delivered to engineers of various disciplines over many years, and will provide invaluable knowledge and understanding of the law of contract as it applies to engineering projects.


    The IChemE UK forms of contract

    23-24 June 2010, London, UK

    The IChemE forms of contract are drafted as performance-based contracts for the design and construction of process plants and other output-based projects. This course examines the suite of contract forms for use in the UK: their applicability to process plant contracts, their approach to risk and payment, and their structure.

    The first day focuses on the duties of the contractor, the various stages of the works, the testing regime, the role of the project manager, looking at the IChemE Red book. The second day looks at risk allocation, the difference between price and cost based contracts and the consequent differences in cost liability, and the different payment terms in the lump sum Red book, the cost reimbursable Green book and the target cost Burgundy book. Reference is also made to the Yellow and Brown books (for subcontracts).


    Process contracts

    This course is designed to help users gain an increased understanding of the Forms of contract available and how to use them to their best advantage. It concentrates on two families of conditions - the IChemE Forms of contract, used in the chemical and process industries and the MF1 Conditions of contract, used in the electrical and mechanical industries. Currently available as an in-company course.


    The IChemE International forms of contract

    This two-day course, intended to be provided anywhere in the world, is currently available as an open course in collaboration with an appropriate industry body or as an in-company course. 

    Process plant contracts are increasingly spanning national borders, and the nature of a process plant contract is such that a form of contract which is drafted specifically for the purpose is necessary. The IChemE International forms of contract meet both of these requirements. They provide various risk/payment profiles (lump sum; cost reimbursable; target cost) allowing the parties to choose the approach best suited to their needs.

    The IChemE International forms of contract are drafted as output-based performance contracts for the design and construction of process plants and other output-based projects. They were first published in 2007, and are based on the very successful and highly-regarded UK forms of contract.
    This course examines the suite of contract forms: their applicability to process plant contracts, their approach to risk and payment, and their structure.

    The first day is focussed on the duties of the contractor, the various stages of the works, the testing regime, the role of the project manager, looking at the IChemE International red book. The second day looks at risk allocation, the difference between price and cost based contracts and the consequent differences in cost liability, and the different payment terms in the three main contract forms – the lump sum International red book, the cost reimbursable International green book and the target cost International burgundy book. Reference is also made to the International yellow book for subcontracts.

    The structure of the contract documentation is explained, such that delegates should have a good understanding of the various provisions of the forms of contract and how a contract is to be compiled.  Advice is given as to when to use each of the three main contract forms. Where possible the course will include contributions from those in the country or region where the course is provided.

    Contact the courses department for further details. 

    In-company training

    IChemE provides in-company courses on contracts and contract law. Courses can range from a broad introduction to the contracts available through to a detailed examination of conditions relating to a particular contract or project. 

    Contact the courses department to discuss your requirements.

    History

    IChemE Red BookIn 1964 IChemE appointed a special committee to review the question of contract conditions for process plants. This led to the publication in 1968 of the first edition of the Model form of conditions of contract for process plant suitable for lump sum contracts.

    Now commonly known as The red book, this new initiative proved popular and successful, prompting IChemE to prepare an equivalent set of conditions for use on reimbursable contracts. The result was the 1976 publication of The green book, or as it was originally titled, the Model form of conditions of contract for process plant suitable for reimbursable contracts.

    At the request of industry, a Subcontract form of contracts, the yellow book, was introduced in 1992. The yellow book offers a ‘back-to-back’ subcontract for use with The red and green books.

    These forms of contract broke new ground in establishing a viable contractual basis, reflecting industry best practice, for the complex way in which purchaser, contractor and subcontractors manage their respective responsibilities on a multidisciplinary process plant project.

    Since then, the series has been further expanded with the publication of in 1998 of The orange book, a minor works contract, followed in 2000 by The brown book, a subcontract for civil engineering works and in 2003 The burgundy book, for the increasingly popular target cost contract format.

    Most recently, in response to the growing use of The red book on projects outside the UK, The international red book, international form of contract – lump sum contracts was published in July 2005. This is a truly international publication, which includes various additional clauses to meet the special requirements of international projects whilst removing any specific reference to UK legislation. This was in the form of a consultation edition with first editions of international red, green, burgundy and yellow due for publication in October 2007.

    A quartet of other titles supports the Forms of contract suite. The grey book, adjudication rules, The white book, rules for expert determination, The pink book, arbitration rules and The beige book, rules for dispute review boards, set out the rules to be followed in the event of a dispute arising under a contract.

    All the contracts are regularly reviewed and updated to reflect changing industry practice, developments in the law and recent legal decisions.
