Interpretation of Clause 12.3 Retesting

Purpose

The primary purpose of Clause 12.3 Retesting is to provide a structured approach for retesting any Works or Sections that initially fail to pass the Tests after Completion. This ensures that both parties are on the same page regarding the next steps following a failure.

Implications

Reiteration of Tests: The clause permits the repetition of failed tests under the same terms and conditions.
Cost Implications: If the Employer incurs additional costs due to the failure and retesting, and if it’s attributable to the Contractor, then the Contractor shall pay these costs to the Employer, subject to Sub-Clause 2.5 [Employer’s Claims].
Interaction with Sub-Clause 11.1: The clause specifies that Sub-Clause 11.1, which deals with the completion of outstanding work and remedying defects, shall apply in case of failure.

Primary Aspects

Trigger for Retesting: Failing the initial Tests after Completion.

Terms and Conditions: Retesting will be done under the same terms and conditions as the initial tests.
Cost Responsibility: The clause outlines scenarios where the Contractor may be responsible for additional costs incurred during retesting.

Interaction with Other Clauses

Clause 5.7 [Operation and Maintenance Manuals]: The retesting procedures are expected to align with the operation and maintenance manuals supplied by the Contractor, thus linking it with Clause 12.3 Retesting.
Clause 8.7 [Delay Damages]: Delays in conducting the retesting could invoke this clause, potentially leading to delay damages against the responsible Party.
Clause 11.9 [Performance Certificate]: The need for retesting could possibly be triggered after the issuance of the Performance Certificate, thereby having an indirect relationship with Clause 12.3.
Clause 11.10 [Unfulfilled Obligations]: While both clauses deal with post-completion responsibilities, they serve different purposes. Clause 12.3 is specific to retesting, while Clause 11.10 covers unperformed obligations in general.
Clause 20.1 [Claims]: Any disputes or disagreements arising from the retesting process could potentially lead to claims, making this clause relevant in the context of Clause 12.3.
Clause 3.5 [Determinations]: Should disagreements or disputes arise regarding the retesting results, this clause may be invoked to make formal determinations, thereby providing a structured approach to resolution.

Flowchart

Detailed Explanation of the Flowchart

Start: Works Fail to Pass Tests After Completion: This is the initial point where the Works or a Section have failed the Tests after Completion. It triggers the subsequent steps.
Invoke Sub-Clause 11.1(b): The next step involves invoking Sub-Clause 11.1(b), which generally pertains to the completion of outstanding work and remedying defects. This sets the stage for the possibility of retesting.
Either Party May Require Failed Tests to be Repeated: Here, either the Employer or the Contractor can request that the failed tests be repeated. This is a decision point that can be initiated by either party involved in the contract.
Retesting Under Same Terms and Conditions: If a retest is required, it will be conducted under the same terms and conditions as initially agreed upon. This ensures consistency in the testing process.
Assess Cause of Failure: After retesting, the cause of the failure is assessed. This is a critical step as it determines the financial implications and next steps.
Cause is Listed in Sub-Clause 11.2(a-d): If the cause of failure is listed in Sub-Clause 11.2(a-d), then the Contractor may be responsible for additional costs incurred by the Employer. This is a key decision point that has financial implications.
Contractor Pays Additional Costs to Employer: If the cause of failure is attributable to the Contractor and is listed in Sub-Clause 11.2(a-d), the Contractor is responsible for paying additional costs to the Employer.
Subject to Sub-Clause 2.5: Any claims for additional costs are subject to Sub-Clause 2.5, which outlines the Employer’s claims process.
End: Resolution: This is the end point, indicating that the process has been resolved, either with or without additional costs.
If Cause is Not Listed in Sub-Clause 11.2: This is an alternative path. If the cause of failure is not listed in Sub-Clause 11.2, then no additional costs are paid by either party.
No Additional Costs Paid: This is the end point for the alternative path, indicating that the process has been resolved without any additional costs.

Block B: Invoke Sub-Clause 11.1(b): This block represents the step where Sub-Clause 11.1(b) is invoked. In the context of FIDIC contracts, Sub-Clause 11.1(b) generally pertains to the completion of outstanding work and the remedying of defects. When the Works or a Section fail to pass the Tests after Completion, this sub-clause is invoked to address the situation. It sets the stage for the subsequent steps, including the possibility of retesting.
Block F: Cause is Listed in Sub-Clause 11.2(a-d): This block comes into play after the cause of the failure in the retesting process has been assessed. If the cause of failure and retesting is attributable to any of the matters listed in Sub-Clause 11.2(a-d), then additional costs incurred by the Employer may be charged to the Contractor. This is a key decision point with financial implications, as it determines whether the Contractor will bear additional costs.

Case Studies

Case Study 1: The Case of Delayed Retesting Due to Natural Disaster

In this scenario, a construction project in North Dakota faced an unexpected natural disaster, causing significant delays in the planned retesting. This situation activated Clause 8.7 [Delay Damages], but because the delay was caused by an unforeseeable event, the Contractor was not held responsible for the damages. However, Clause 12.3 Retesting was invoked to ensure that retesting was carried out under the same terms and conditions once conditions were favorable.

Case Study 2: The Case of Flawed Manuals

In a project in New York, the Contractor supplied flawed operation and maintenance manuals under Clause 5.7 [Operation and Maintenance Manuals]. When retesting was performed, it resulted in failure, thereby activating Clause 12.3 Retesting and Clause 20.1 [Claims] for dispute resolution. The Contractor had to revise the manuals and bear the cost of retesting.

Case Study 3: The Case of Unfulfilled Obligations

In a construction project in California, the Contractor left certain obligations unfulfilled after the issuance of the Performance Certificate under Clause 11.9 [Performance Certificate]. Clause 11.10 [Unfulfilled Obligations] was activated, and it was decided that retesting under Clause 12.3 was necessary to ensure all work met the project specifications.
