The FIDIC Gold Book: Design-Build-Operate Contracts

Published in 2008, the FIDIC Gold Book combines design-build with a long-term operation commitment in a single contract. For UAE infrastructure projects where a single contractor is to deliver and run the asset for up to 20 years, the Gold Book provides a ready-made framework — though it requires careful tailoring to work well.

Key takeaway

The Gold Book is the right starting point for UAE projects that combine delivery and long-term operation under a single contract — treatment plants, waste facilities, and certain infrastructure assets. It presupposes a green-field site, a 20-year operation period, and a single contracting entity. Where any of these assumptions does not hold, heavy amendment through the Particular Conditions is required, and a bespoke form may be more honest than a tailored Gold Book.

1. What the Gold Book is

The FIDIC Gold Book — formally, Conditions of Contract for Design, Build and Operate Projects, First Edition 2008 — addresses a procurement model the earlier FIDIC suite did not cover. The Red, Yellow and Silver Books end at handover. The Gold Book continues: after design and construction, the Contractor operates the facility for a defined period before handing it back to the Employer.

In drafting approach, the Gold Book is closer to the Silver Book than to any other FIDIC form. The Contractor takes broad responsibility for design, construction and operation, and the Employer takes the performance risk at the end. The form is drafted for green-field projects on a 20-year operation period, with both defaults capable of modification in the Particular Conditions.

The Gold Book does not address financing. Unlike BOT or PPP arrangements where the Contractor or a project company raises finance against future revenues, the Gold Book assumes the Employer funds the project and owns the asset throughout. Commercial success of the operation is also an Employer risk.

2. The DBO procurement model

Design-Build-Operate procurement bundles three phases into a single contract:

• Design — the Contractor develops the detailed design from the Employer’s Requirements.
• Build — the Contractor constructs and commissions the facility.
• Operate — the Contractor operates and maintains the facility for the defined Operation Service Period, typically 20 years.

The commercial logic is to align incentives across the asset life-cycle. A Contractor who will operate the facility for 20 years has a strong interest in designing and building it well, because operation costs fall on the Contractor. This contrasts with traditional procurement, where separate contracts for construction and for operation can produce incentive misalignment — the construction contractor optimises for construction cost, not for whole-life cost.

DBO is particularly common for:

• Water and wastewater treatment plants.
• Solid waste treatment and disposal facilities.
• Certain power assets, although these are often procured under bespoke PPA-linked forms.
• Specialist industrial facilities where operating competence is closely tied to design choices.

In UAE practice, DBO-style procurement has been used for water treatment and certain waste management assets, sometimes under bespoke forms rather than the Gold Book itself. Where the Gold Book has been used, it is typically with Particular Conditions addressing UAE law, UAE authorities’ approval regime, and local content requirements.

3. Structure and operation period

The Gold Book adopts the standard FIDIC structure:

• General Conditions — core terms applicable across DBO projects.
• Particular Conditions — Part A (Contract Data) and Part B (Special Provisions) for project-specific modifications.
• Sample Forms — securities, guarantees, and other standard documents.

The operation period — called the Operation Service Period — is defaulted to 20 years. The commentary accompanying the form warns that the General Conditions are drafted for this default and that significantly shorter or longer periods may require substantive amendment, not just a change to the period figure in the Contract Data.

The contract is divided into three milestones:

• Commissioning Certificate — issued when the facility passes the Commissioning Tests, marking the end of the Design-Build Period and the start of the Operation Service Period.
• Contract Completion Certificate — issued at the end of the Operation Service Period, subject to passing the Tests Prior to Contract Completion.
• Operational Performance — maintained throughout the Operation Service Period, with deductions or bonuses depending on performance against KPIs set out in the Operation Management Requirements.

4. Roles and responsibilities

The Gold Book retains the Employer, Contractor and Employer’s Representative structure familiar from the Silver Book, with adaptations for the operation phase:

5. Extension of Time and claims under the Gold Book

The Gold Book handles claims through a clause structure similar to the 1999 Silver Book, adapted for the two-phase Design-Build Period and Operation Service Period. EOT entitlement applies primarily to the Design-Build Period, with separate machinery for the Operation Service Period addressing delay in rectifying defects and delay attributable to the Employer.

The principal grounds for extension to the Design-Build Period include:

• Variations instructed by the Employer.
• Events specifically giving rise to EOT entitlement under the Conditions — including delayed access, suspension by the Employer, and changes in Laws.
• Exceptionally adverse climatic conditions.
• Unforeseeable shortages caused by epidemic or governmental action.
• Delay, impediment or prevention attributable to the Employer.
• Exceptional Events (force majeure).

The notice regime for claims under the Gold Book follows the pattern of the 1999 suite: a 28-day notice requirement, with full supporting particulars to follow. The consequences of late notice are the same as under the Red, Yellow and Silver Books — loss of the right to an extension of time and to additional payment. Claims preparation on Gold Book projects often involves separating Design-Build Period claims, which follow the familiar FIDIC pattern, from Operation Service Period claims, which engage different mechanisms.

During the Operation Service Period, performance is measured against the KPIs in the Operation Management Requirements. Where the Contractor fails to meet those KPIs, deductions apply. Where the Employer prevents the Contractor from performing — for example, by delaying delivery of an input the Employer was to supply — the Contractor may claim relief from the performance deduction. The machinery is closer to a long-term services contract than to a traditional construction claim.

6. Dispute avoidance and resolution

The Gold Book provides for a standing Dispute Adjudication Board — an innovation at the time of publication in 2008, later carried across the full suite in the 2017 Conditions as the Dispute Avoidance/Adjudication Board. On DBO projects spanning 20 years or more, a standing board offers continuity and familiarity with the project that an ad hoc appointment cannot.

The board’s role extends beyond formal dispute decisions. Under the Gold Book, the parties may jointly request informal assistance on issues that have not crystallised into disputes — a mediation-style function that has since been formalised in the 2017 suite. This is particularly valuable in long-term contracts where preserving the working relationship matters as much as resolving any single issue.

If a party is dissatisfied with the board’s decision, the dispute proceeds to arbitration. On UAE-seated arbitrations, Federal Arbitration Law No. 6 of 2018 provides the framework, with DIAC as the principal local institution. Where the project involves international parties or offshore financing, ICC or LCIA seats are sometimes chosen instead.

7. Practical considerations for UAE DBO projects

Four points recur in UAE practice on Gold Book and Gold-Book-derived DBO projects:

First, the Particular Conditions carry more weight than usual. The Gold Book’s defaults — green-field site, 20-year operation, single entity Contractor — frequently require modification. Well-drafted Particular Conditions addressing a brown-field site, a different operation period, or a consortium Contractor can preserve the benefit of the form. Poorly drafted amendments can undermine it.

Second, UAE authority approvals need to be mapped onto the contract programme. DBO projects typically require multiple approvals from federal and emirate authorities — municipality, environment agencies, utility authorities, and sector-specific regulators. Delay in obtaining approvals is a frequent cause of dispute. Allocating the approval risk clearly in the Particular Conditions avoids later argument.

Third, handback condition is a long-term issue. The Gold Book provides for Tests Prior to Contract Completion to verify that the facility is handed back in acceptable condition. Specifying these tests precisely at drafting stage — rather than leaving them for later agreement — reduces disputes at the end of the Operation Service Period. Disputes over handback are exceptionally expensive to resolve because they arise at the point the commercial relationship is ending.

Fourth, record-keeping over 20 years is an institutional challenge. Contemporaneous records of design decisions, construction quality, operational performance and Employer interventions need to be preserved across a period longer than many staff careers. The Contractor’s record-keeping system should be designed for this from the outset, not adapted from a five-year construction contract template.
