Key takeaway

The FIDIC Green Book is a Short Form of Contract designed for simple, low-value works. Its guidance notes suggest a capital value threshold around USD 500,000, although the form is flexible enough to be used above that in limited circumstances. The Green Book has no independent Engineer, relies on adjudication for early dispute resolution, and should not be used as a general-purpose substitute for the Red or Yellow Books on UAE projects of any meaningful scale.

1. What the Green Book is

The FIDIC Green Book, published as a First Edition in 1999, is the Short Form of Contract within the Rainbow Suite. It is a single, slim document intended to provide the essential administrative and commercial terms for building and engineering works of relatively small capital value, without the full machinery of the Red or Yellow Books. The form can accommodate either Employer-led or Contractor-led design and, with amendments, a mix of the two.

2. Structure of the Short Form

The Green Book comprises four components:

• The Agreement — the parties’ core contractual terms, including scope, price, commencement and completion dates.
• General Conditions — the standard terms on payment, variations, delays, suspension and termination.
• Rules for Adjudication — the procedural rules for resolving disputes by adjudication as a first-tier mechanism.
• Notes for Guidance — non-contractual guidance on preparing tender and contract documents, including the threshold for use.

The form is designed to be adapted through an Appendix where the parties can record project-specific information without rewriting the General Conditions. Heavy amendment is typically a signal that a different Book would have been more appropriate.

3. When the Green Book is appropriate

The Notes for Guidance identify the Green Book as suitable for engineering and building work of relatively small capital value — indicatively around USD 500,000 — and for simple, repetitive or short-duration works that do not require specialist sub-contracts. Typical candidate projects include small refurbishments, finishing packages, minor civils, discrete MEP replacements and short-duration fit-out works.

The form can in principle be used above the indicative threshold where the works remain simple. In practice, we would caution against using the Green Book on UAE projects where any of the following are present: significant design co-ordination across disciplines, interface with existing operating facilities, complex variations, or contract values where liquidated damages and performance security would run into seven figures.

4. The absence of an independent Engineer

Unlike the Red, Yellow and Gold Books, the Green Book does not provide for an independent Engineer. Instead, it appoints a member of the Employer’s personnel as the authorised person responsible for administering the contract, issuing instructions, certifying payments and determining matters that the Engineer would deal with under the longer forms.

For the Contractor, this is a material point. It removes the first-tier neutral decision-maker from the contract and places early determinations in the hands of an Employer-appointed individual. The Rules for Adjudication are the counterweight to this — but they only operate once a dispute has crystallised, which is typically later than a Contractor would wish.

5. Extension of Time under the Green Book

The Green Book contains Extension of Time provisions within its General Conditions that broadly mirror the structure of the longer FIDIC Books, though in condensed form. The Contractor may be entitled to an extension where completion is delayed by causes outside its control and within the classes of event identified in the contract, including (subject to the precise wording of the edition in use):

• Variations and changes instructed by the Employer;
• Exceptionally adverse climatic conditions;
• Acts or omissions of the Employer or persons for whom it is responsible;
• Force majeure events;
• Unforeseeable shortages of personnel or Goods caused by specified external events.

The Green Book does not contain the detailed notice regime of Red Book Sub-Clause 20.1 (1999) or Sub-Clause 20.2.1 (2017), but written notice and supporting particulars remain essential both as a matter of good contract management and to discharge the Contractor’s general duty to keep the Employer informed. Delay analysis should be supported by an updated programme and records consistent with the SCL Delay and Disruption Protocol (2nd edition, 2017). For more detail on these methodologies see our Delay Analysis service.

6. Adjudication as the dispute resolution route

The Green Book incorporates Rules for Adjudication as its primary dispute resolution tool. A single adjudicator is appointed (either at the outset or upon a dispute arising, depending on how the Appendix is completed) and issues a decision which is binding on the parties unless and until revised by arbitration or agreement. Adjudication under the Green Book is typically faster and less costly than Red Book DAB/DAAB proceedings and can be a practical advantage on small projects.

Practitioners should note that adjudication enforcement in the UAE differs from the position in jurisdictions with dedicated construction adjudication statutes such as the United Kingdom. A Green Book adjudicator’s decision is a contractual remedy; giving it enforceable effect in the UAE typically requires either compliance by the losing party, or arbitration under Clause 10 (or its equivalent in the relevant edition) followed by recognition of the resulting award under UAE Federal Arbitration Law No. 6 of 2018.

7. Practical use on UAE projects

We encounter the Green Book on UAE projects less often than the Red or Yellow Books, and typically in two contexts: small works packages let by developers as a secondary form alongside a main contract, and subcontract packages where a consultant has recommended the Short Form for its brevity. In both cases, the key drafting point is to ensure the Appendix records the governing law, the arbitration seat and rules (commonly DIAC or DIFC-LCIA), the authorised person’s identity, and the liquidated damages rate. Where any of those are left blank, the contract administration consequences can be severe.
