FIDIC Site Instruction Form – Free Download and Usage Tips

Introduction
In any FIDIC contract, the Engineer has the authority to issue instructions to the contractor to ensure proper execution of the works. These Site Instructions are legally binding and must be complied with immediately, regardless of whether they come on an official form, in meeting minutes, or via marked-up drawings.

This mini guide focuses specifically on the FIDIC Site Instruction form we designed at Quollnet — a practical tool for documenting, tracking, and managing instructions in a way that aligns with FIDIC’s requirements and reduces the risk of disputes.

About Clause Numbering

Note: In the FIDIC 1999 and 2017 Red Book editions, Engineer’s Instructions are addressed in Clause 3.3. In earlier FIDIC versions (such as the 1977 and 1987 editions), the numbering differs, but the underlying principle — the Engineer’s authority to issue instructions — is the same. Always check your specific contract edition for the correct clause reference.

Purpose of the Form

The form provides a standardized method to issue instructions, ensuring:

• Clear, concise communication of the directive.

• Proper contractual reference and supporting documentation.

• Traceability through the Site Instruction Register.

• A direct link between the instruction, related variations, and potential claims under Clause 20.

When to Use the FIDIC Site Instruction Form

While Engineer’s Instructions can be issued in many formats, the dedicated form should be used when you want a clear, auditable record. Common scenarios include:

• Design clarifications or corrections.

• Safety measures requiring immediate action.

• Coordination changes between trades.

• Appointment of nominated subcontractors.

• Owner-requested changes for convenience.

• Instructions due to unforeseen site conditions.

• Remedial work following non-conformance reports.
