Contractor Rights and Claims Arising from Delayed Payments under Construction Contracts
In construction contracts, the timely payment to contractors is a primary obligation of the employer and is usually controlled through an intermediary, often referred to as the Engineer or Project Manager. Standard forms of contracts, such as FIDIC, NEC, or JCT, state clear timelines and procedures for certifying and releasing interim payments. Failure to hold to these timelines can lead to major financial and operational consequences for contractors, potentially causing delays, disruption, or even cessation of work.
Delayed payments not only affect the contractor’s cash flow but also threaten the overall progress and completion of the project. In such scenarios, contractors must understand their contractual entitlements, solutions available, and the potential legal and operational consequences. This article examines contractor entitlements when payments are delayed and the connection between delayed payments and entitlement to an Extension of Time (EOT).
Payment Timelines in Standard Contracts
Under most standard construction contracts, there are well-defined procedures and timelines for the Engineer or Employer to certify and release interim payments. For instance, the FIDIC Red Book specifies that the Engineer must certify a payment application within 28 days, and the Employer must release the payment within 56 days from the date of the application. Similarly, JCT contracts generally require payments to be made within 14 days after the due certification date, while NEC contracts often demand payments within 21 days of the assessment date.

These timelines are not arbitrary; they are determined to maintain financial stability for the contractor, ensuring smooth workflow and timely project delivery. When these timelines are violated, the contractor is placed in an unstable position, often requiring additional financing to sustain operations, which can lead to financial losses and disturbances.

Contractor Solutions for Delayed Payments
When payments are delayed, contractors have several possibilities under standard contractual provisions. One of the most common decisions is the suspension of work, which is clearly permitted under many contract forms, such as FIDIC (Sub-Clause 16.1). Suspension is not a step taken lightly, as it can further escalate delays and increase costs for both parties. However, it is sometimes necessary to protect the contractor from accumulating unsustainable financial troubles. And if you want to know more about how to deal with suspension of work you can check this article.
In addition to suspension, contractors are typically entitled to interest on late payments. The interest rate is often pre-defined in the contract and serves as compensation for the financial costs incurred due to non-payment. Beyond interest, contractors may also claim additional costs incurred from securing alternative financing, such as bank loans or credit facilities, to maintain progress on-site.
In extreme cases, extended non-payment may grant the contractor the right to terminate the contract entirely, an extreme step that is often followed by claims for damages and loss of profit.

Extension of Time (EOT) Claims Due to Payment Delays
The question of whether delayed payments justify an Extension of Time (EOT) is more complex. An EOT claim depends largely on whether the delay in payment has a direct impact on the contractor’s ability to progress with the works.
For example, if a contractor is unable to procure essential materials or mobilize key subcontractors due to delayed payments, and this directly impacts the critical path of the project, they may have a valid claim for an EOT. On the other hand, if the delay in payment causes only financial damage but does not physically disrupt site activities, the contractor might not be entitled to an EOT but may still claim for financial compensation.
The cause-and-effect relationship between delayed payments and project delays must be carefully documented and presented to support such claims. Additionally, If you like to know more about how to make EOT claims, you can check our course.

Violation of Contract and Legal Implications
From a legal perspective, failure to release payments within the specified timeframe often constitutes a breaking of contract or in other words failure to fulfill a clause of the contract. Both the Employer and the Engineer have a duty to administer the contract fairly and in accordance with its terms.
When these duties are neglected, whether through repeated delays in certification or considered preservation of payments, the Employer risks being held in breach of contract. Such breaches can have severe consequences, including financial penalties, damage claims, and reputational harm.
Furthermore, failure to make payments as per the contract terms weakens trust between the contracting parties and creates an oppositional project environment, which can risk successful project delivery.
Practical Recommendations for Contractors
To navigate these situations effectively, contractors must adopt a proactive approach. They should issue formal notices of delayed payments in strict compliance with the contractual notice requirements. Detailed records of financial impacts, correspondence, and project delays caused by payment delays must be carefully maintained.
Before suspending work or terminating the contract, contractors should seek expert legal and contractual advice to ensure their actions are fully compliant with the contract terms and local laws.
Conclusion
Delayed payments in construction contracts can have far-reaching consequences, affecting not only project progress but also financial stability and contractual relationships. Contractors have clear entitlements under standard contract provisions, including suspension of works, claims for interest, compensation for financing costs, and, in extreme cases, termination.
Whether delayed payments justify an EOT depends on whether they directly impact project progress or simply create financial difficulty. Employers and Engineers must recognize the importance of sticking to payment timelines and administering contracts responsibly to prevent disputes and maintain positive working relationships.
By understanding their rights, documenting their claims, and following contractual procedures, contractors can effectively protect their interests and ensure that payment delays do not disrupt project success.
