Payment For Variation Works (FIDIC) With No Instruction

What Is FIDIC:

FIDIC, which stands for the International Federation of Consulting Engineers, is a globally recognized organization that plays a crucial role in the construction and engineering industry. Established in 1913, FIDIC aims to promote excellence and professionalism in consulting engineering services worldwide. One of its most significant contributions lies in the development of standard forms of contracts that are widely used in the construction sector. FIDIC contracts provide a fair and balanced framework for defining the rights and responsibilities of all parties involved in a construction project, including the employer, contractor, and engineer. These contracts are renowned for their comprehensive nature and their ability to address various aspects of a project, such as design, construction, and procurement. With its commitment to fostering international cooperation and best practices, FIDIC continues to shape the industry’s landscape, facilitating successful and harmonious project execution across different jurisdictions.



In the realm of construction projects, the management and payment for variations—changes to the original scope of work—are often complex and challenging. Among the various intricacies that arise in this context, one particular issue that can cause significant disputes is the payment for variations of works that were executed without explicit instruction. These uninstructed works, where contractors undertake additional tasks or modifications without receiving a formal directive from the employer or engineer, present a unique set of challenges and require careful consideration within the contractual framework. In this article, we will delve into the complexities surrounding the payment process for such variations. 


Understanding the Nature of Variations Works with No Instruction:

Variations in construction projects can arise due to a multitude of reasons, such as design changes, unforeseen site conditions, or client preferences. Typically, when a variation is required, the contract may outline specific procedures for the employer or engineer to issue instructions to the contractor, detailing the scope, cost, and time implications of the change. However, there are instances where variations of work are carried out by the contractor without receiving explicit instructions from the employer or engineer. This can occur due to various factors, including urgency, lack of communication, or a genuine belief by the contractor that the additional work is necessary to meet project requirements.


Challenges and Considerations for Payment:

When it comes to uninstructed variations works, the payment process becomes inherently complicated. The absence of formal instructions raises questions regarding the entitlement of the contractor to compensation for the additional work performed. Employers may argue that without explicit instruction, they are not obligated to pay for the variations. Conversely, contractors may claim that the additional work was necessary for project completion and that they should be fairly compensated. In such situations, several key considerations come into play:


Contractual Framework: The first step in dealing with uninstructed variations works is to carefully examine the contract provisions. The contract should be analyzed to determine whether it allows for payment of variations carried out without explicit instruction. Specific clauses related to variations, change management, and payment terms need to be thoroughly reviewed to understand the rights and obligations of each party.


Implied Instructions: In certain cases, even in the absence of explicit instruction, contractors may argue that there was an implied instruction to proceed with the additional work. They may present evidence such as project meetings, correspondence, or site conditions that support their claim. Proving the existence of an implied instruction requires careful documentation and a clear understanding of the project dynamics.


Notice Requirements: Contractors should be aware of any notice requirements stipulated in the contract. Timely notification to the employer or engineer regarding the additional work is crucial to establish a valid claim for payment. Failure to provide adequate notice within the contractually defined timeframe may weaken the contractor’s position.


Quantification of Costs: Determining the cost implications of uninstructed variations works can be challenging. Contractors should maintain meticulous records, including detailed measurements, resource allocation, and material costs, to accurately quantify the additional expenses incurred. Proper documentation will strengthen their case when negotiating payment with the employer.


Mitigation of Losses: Contractors have a duty to mitigate their losses when executing variations works without instruction. This involves taking reasonable steps to minimize costs and prevent unnecessary or excessive work. Employers may argue that contractors failed to mitigate their losses, which could impact the payment negotiations.


Navigating Uninstructed Variations Works:

To navigate the payment process for uninstructed variations effectively, it is essential for both employers and contractors to adopt a collaborative and proactive approach. Consider the following strategies to minimize conflicts and achieve fair outcomes:


Open Communication: Establish and maintain open lines of communication between all project stakeholders. Regular project meetings, progress reports, and documentation of discussions can help ensure that all parties are aware of potential variations and can address them promptly.


Early Notification: Contractors should promptly notify the employer or engineer of any perceived variations, even if explicit instructions have not been provided. Early notification allows for timely discussions, assessments, and decision-making, mitigating the risk of disputes down the line.


Negotiation and Agreement: When uninstructed variations arise, it is crucial for employers and contractors to engage in constructive negotiations to reach a mutually agreeable resolution. This may involve assessing the necessity and value of the additional work, considering project constraints, and finding a fair compromise that accounts for the interests of both parties with proper legal advice from well-qualified lawyers.



Payment for variations works without explicit instruction poses unique challenges in construction projects. Contractors may find themselves in a precarious position when seeking compensation for additional work undertaken without formal directives. By understanding the contractual framework, documenting evidence of implied instructions, adhering to notice requirements, quantifying costs, and actively mitigating losses, contractors can strengthen their position in payment negotiations. Similarly, employers should approach uninstructed variations with openness, fairness, and a willingness to engage in constructive discussions. Ultimately, effective communication, proactive notification, negotiation, and the use of dispute resolution mechanisms can help navigate the complexities of payment for uninstructed variations.
