FIDIC Green Book (Short Form of Contract) · International Contracts
The FIDIC Green Book, officially titled the *Short Form of Contract*, was first published by the International Federation of Consulting Engineers (FIDIC) in 1999. It is the shortest and most streamlined standard form of contract in the FIDIC family. Together with the earlier Red Book (Conditions of Contract for Construction), Yellow Book (Conditions of Contract for Plant and Design-Build), and Silver Book (Conditions of Contract for EPC/Turnkey Projects), it forms the FIDIC 1999 suite of contracts. In 2017, FIDIC issued major revisions to the Red, Yellow, and Silver Books, but the Green Book remains predominantly used in its 1999 edition as of now (please refer to official FIDIC documentation for any newer edition).
Background: In the 1990s, FIDIC recognized that for small to medium-sized projects with short durations, low contract values, and limited technical complexity, using heavy-weight conditions such as the Red Book created clear problems of "over-administration" — cumbersome procedures, high management costs, and excessive tiers of dispute resolution. The Green Book was therefore specifically designed with the core philosophy of "simplicity, flexibility, and low cost" to lower the threshold for contract administration.
Scope of Application: The Green Book is suitable for projects with the following characteristics:
The Green Book may be used for civil engineering, building, electrical, mechanical, and other types of works. It does not mandate the appointment of an Engineer — the Employer may administer the contract directly or appoint a representative.

The General Conditions of the Green Book contain only about 15 clauses, far fewer than the Red Book's 20 clauses and 70-plus sub-clauses. The structure is as follows:
| Clause No. | Main Content | Comparison with Red Book |
|---|---|---|
| 1 | General Provisions | Definitions significantly streamlined |
| 2 | The Employer | Simplified obligations |
| 3 | Employer's Representative | Optional "Employer's Representative" replaces "Engineer" |
| 4 | The Contractor | Generalized obligations |
| 5 | Design | Contractor may undertake partial design |
| 6 | Employer's Responsibilities | Site, permits, etc. |
| 7 | Payment | Simplified payment procedures |
| 8 | Time for Completion | Commencement, completion, extension |
| 9 | Taking Over | Tests on completion and taking over |
| 10 | Defects Liability | Defects notification period |
| 11 | Variations and Adjustments | Simplified variation procedures |
| 12 | Claims | Streamlined procedures |
| 13 | Disputes | Arbitration or litigation |
| 14 | Risk and Insurance | Basic risk allocation |
| 15 | Termination | Grounds for termination |
Key Feature: The Green Book does not provide for an "Engineer" role. Instead, an "Employer's Representative" exercises administrative functions, and this representative may be an internal staff member of the Employer — an independent third party is not mandatory.
The Green Book offers flexible payment methods, typically one of the following:
The payment procedure is extremely simplified: Contractor submits payment application → Employer's Representative reviews within the agreed period → Employer pays. There is no complex mechanism such as an "Interim Payment Certificate."
Tips for General Contractors: Under the Green Book, the trigger point for the Employer's payment obligation depends more heavily on the Special Conditions. If the Special Conditions do not specify a payment period, disputes are likely to arise. It is advisable to specify the payment period and interest on late payment in the Special Conditions.
| Matter | Green Book Approach | Impact on Contractor |
|---|---|---|
| Variation instruction | Employer's Representative may instruct variations in writing | Must promptly confirm whether it constitutes a variation |
| Variation valuation | Per contract agreement or negotiation | No independent Engineer to adjudicate; negotiation can be difficult |
| Claim notice | Written notice within specified period | Period is typically short; high vigilance required |
| Dispute resolution | Direct arbitration/litigation | No DAB (Dispute Adjudication Board) as a precondition |
Core Risk: The Green Book has no DAB mechanism — disputes proceed directly to arbitration or litigation, meaning that once a dispute arises, the resolution cost is relatively high. For general contractors, upfront contract negotiation and contemporaneous record-keeping are particularly important.
Default risk allocation principles under the Green Book:
Compared with the Red Book, risk allocation under the Green Book relies more on the Special Conditions. The General Conditions themselves are fairly balanced but briefly worded, making it easy for the Employer to tilt the balance during Special Conditions negotiations.
The defects notification period is typically 12 months (negotiable), during which the Contractor must remedy defects. Termination provisions are simplified — both the Employer and Contractor may terminate under specified circumstances, but the compensation mechanism is broadly stated.

| Comparison Dimension | FIDIC Green Book | Chinese National Standard (e.g., GF-2017-0201) | Other International Standards (e.g., NEC3/4) | Local Standards (e.g., Middle East, Africa) |
|---|---|---|---|---|
| Applicable project size | Small to medium, simple projects | Various, leaning toward large | Various, flexible | Per local regulations |
| Contract administration role | Employer's Representative (optional) | Supervising Engineer (mandatory) | Project Manager (PM) | Per local rules |
| Dispute resolution | Direct arbitration/litigation | Supervision → Arbitration/Litigation | Adjudicator → Arbitration | Per local law |
| Procedural complexity | Low | Medium-High | Medium | Varies |
| Design responsibility | Flexibly allocated | Typically Employer-designed | Flexible | Per local practice |
| Payment mechanism | Simplified | Detailed | Project Bank mechanism | Varies |
Implications for General Contractors: The Green Book has the lightest procedures but the shortest route to dispute resolution, meaning that risk prevention through Special Conditions deserves greater attention during contract negotiation. Under the Chinese national standard, the supervision system is well-established, whereas under the Green Book, the Employer's Representative holds concentrated power — their authority boundaries should be clearly defined in the Special Conditions.

Scenario 1: A Small Building Project in Southeast Asia
Under the Belt and Road framework, some small building and factory projects undertaken by Chinese SOEs in Southeast Asia involve modest contract values and short durations, with local enterprises or government agencies as Employers. Such projects often adopt the FIDIC Green Book to simplify contract administration. For example, publicly reported small industrial factory projects by Chinese enterprises in Cambodia and Laos have tended to choose the Green Book or similar short-form conditions.
Scenario 2: A Water Supply or Road Maintenance Project in Africa
In parts of Africa, small water supply and road maintenance projects funded by international financial institutions often adopt the FIDIC Green Book. Such projects are technically simple with short durations, and the Employer's management capacity is limited — the Green Book's simplicity fits the need. According to public reports, some projects funded by the World Bank and the African Development Bank have used the Short Form of Contract.
Scenario 3: An Electrical Installation Subcontract in the Middle East
In the Middle East, when general contractors subcontract specialized works such as electrical installation, the subcontract sometimes uses the Green Book as a template. Such subcontract works have a clear scope and short duration, and the Green Book's flexibility facilitates rapid signing.
Note: The above scenarios reflect common industry practice. Whether a specific project adopts the Green Book should be verified against the project's tender documents or official public information.

Q1: What is the core difference between the Green Book and the Red Book?
A: The core difference lies in the management structure and procedural complexity. The Red Book provides for an "Engineer" role with detailed procedures; the Green Book provides for an "Employer's Representative" with extremely streamlined procedures, suitable for small to medium-sized projects. The Green Book has no DAB — disputes go directly to arbitration.
Q2: Can the Contractor claim under the Green Book?
A: Yes, but the claims procedure is more streamlined and the notice period is typically shorter. The Contractor must give written notice within the period specified in the Contract, failing which the right to claim may be lost. It is advisable to specify the claims period and procedure in the Special Conditions.
Q3: Does the Green Book mandate that the Employer appoint an independent Engineer?
A: No. The Green Book allows the Employer to self-administer or appoint an Employer's Representative — no independent third party is required. This is an important distinction from the Red Book.
Q4: How is the payment period stipulated under the Green Book?
A: The General Conditions do not specify a particular period — it must be defined in the Special Conditions. General contractors are advised to clarify the payment period, interest on late payment, and the right to suspend work during negotiations.
Q5: Is the Green Book suitable for EPC projects?
A: Generally not for large-scale EPC projects. The Silver Book is typically recommended for EPC projects. The Green Book is better suited for small to medium-sized projects with simple design responsibility and short durations.

1. Special Conditions negotiation is paramount: The Green Book's General Conditions are brief, and risk prevention relies primarily on the Special Conditions. Review payment, variation, claims, and termination clauses clause by clause to avoid one-sided tilting by the Employer.
2. Define the boundaries of the Employer's Representative's authority: Under the Green Book, the Employer's Representative holds concentrated power. It is advisable to specify their instruction authority, variation authority, and approval timeframes in the Special Conditions to prevent arbitrary administration.
3. Establish a strict claims notification register: Claims periods under the Green Book are short. Project teams should maintain a claims event register to ensure written notices are issued within the contractual time limits.
4. Payment terms must be clearly defined: Specify the payment period, interest on late payment, right to suspend work, and termination rights in the Special Conditions to avoid being put in a passive position due to payment disputes.
5. Prefer arbitration in dispute resolution clauses: The Green Book has no DAB. It is advisable to agree on international arbitration (e.g., ICC, SIAC) in the Special Conditions, and to specify the seat of arbitration and governing law.
6. Insurance and guarantee clauses must match the laws of the project's host country: The Green Book's insurance provisions are brief. It is advisable to specify insurance types, insured amounts, and beneficiaries in the Special Conditions in accordance with the host country's laws and the Employer's requirements.
7. Contract language and governing law must be clearly stated: For cross-border projects, it is advisable to agree on English as the contract language and to choose the law of a neutral third country or international practice as the governing law to reduce legal risk.
8. Contemporaneous record management must not be relaxed: The Green Book simplifies procedures, but the route to dispute resolution is short. Contemporaneous records (meeting minutes, instructions, correspondence) are key evidence in dispute resolution — project teams should maintain complete records.
