Summary
The dispute centered on the determination of the appropriate interest rate for pre-judgment damages awarded to Terrenus. The court was tasked with evaluating whether the plaintiff was entitled to interest based on its alleged borrowing costs or a lower rate reflective of deposit interest. The plaintiff failed to provide sufficient evidence to justify the application of a commercial lending rate, specifically failing to demonstrate that the non-payment of damages necessitated additional borrowing from financial institutions. Consequently, the court rejected the plaintiff's submission that a 5.33% interest rate was appropriate, noting the lack of empirical support in the plaintiff's filings.
In its ruling, the court adopted the evidence provided by the defendant, Attika, which demonstrated that the average fixed deposit rate for the relevant period (2020–2021) was approximately 0.18%. The court held that this rate represented a reasonable proxy for the loss suffered by the plaintiff due to the delay in payment. This decision reinforces the evidentiary burden placed on claimants under s 103(1) of the Evidence Act to substantiate claims for pre-judgment interest. The judgment clarifies that in the absence of proof of actual borrowing costs, the court will favor verifiable market data, such as fixed deposit rates, to determine compensatory interest, thereby preventing the over-compensation of plaintiffs.

What Were the Facts of This Case?
Terrenus Energy SL2 Pte Ltd (Terrenus) and Attika Interior + MEP Pte Ltd (Attika) entered into a lump sum contract on 5 April 2021 for the construction of a Ground Mount Solar Generation Facility and a Linkway Solar Generation Facility at Changi Business Park. Under the agreement, Attika was appointed as the main contractor responsible for the installation, testing, and commissioning of the solar arrays, while Terrenus remained responsible for supplying critical components like solar panels and containerized substations.
The project encountered significant friction, leading to a dispute over three major categories of alleged defects: the depth of peg rods, the above-ground clearance of the structures, and the removal of root balls from the site. Terrenus contended that these defects compromised the structural integrity and compliance of the facility, while Attika maintained that the works were performed according to the agreed specifications.
Beyond the physical defects, the case centered on the timeline of the project. Both parties disagreed on when partial completion was achieved and whether Attika was entitled to extensions of time (EOT) for various delays, including those related to regulatory approvals from NParks and the installation of mobile substations by a third-party subcontractor, Bulox Power Pte Ltd.
The litigation was propelled by Terrenus's claim for liquidated damages and general damages arising from the alleged delays and defects. Conversely, Attika counterclaimed for the balance of the contract sum, arguing that it had fulfilled its obligations and was entitled to payment under the payment schedule set out in the Main Builder Agreement.
What Were the Key Legal Issues?
The dispute in Terrenus Energy SL2 Pte Ltd v Attika Interior + MEP Pte Ltd [2023] SGHC 333 centers on the interpretation of contractual completion obligations and the allocation of delay risks in a solar farm construction project.
- Determination of Partial Completion: Whether the requirement to "commission and energize" under clause 1.3.12 of the Master Building Agreement (MBA) necessitates connection to the national grid or merely localized testing, and the identification of the operative date for such completion.
- Substantial Completion of Works: Whether the defendant's works were completed in accordance with the contract, specifically addressing whether alleged defects in ground clearance and rod embedment depth precluded a finding of completion.
- Allocation of Delay Risk for Regulatory Approvals: Whether the contractor (Attika) or the employer (Terrenus) bears the risk of delays caused by public authorities (specifically NParks) in the context of the "Schedule Division of Work" (Annex B) and clause 15 of the MBA.
How Did the Court Analyse the Issues?
The court first addressed the definition of "Partial Completion." Rejecting Terrenus’s argument that sale of electricity to the national grid was required, the court held that the plain language of the MBA focused on localized commissioning. Relying on the COPS documents as the objective record of testing, the court determined that the date of the final substation commissioning (23 November 2021) constituted the date of Partial Completion.
Regarding the completion of the works, the court applied the common law doctrine of substantial completion. Since Terrenus failed to prove that the alleged defects were "substantial," the court concluded that the works were effectively completed on the same date as Partial Completion, 23 November 2021.
The court then turned to the allocation of delay risk. Terrenus argued that clause 15.1.2, which mandates compliance with public authorities, placed the risk of regulatory delay on Attika. The court rejected this, finding that Item B4 of the "Schedule Division of Work" explicitly assigned the responsibility for "submission and approval to technical agencies" to Terrenus’s consultant, PEC.
The court emphasized that "it is Terrenus (through its consultant PEC) and not Attika, that bears the risk of any late submission or delayed approval." Consequently, the court found that Attika was entitled to an extension of time (EOT) for the period of delay caused by NParks, including a reasonable one-day mobilization period following the approval.
Finally, regarding pre-judgment interest, the court noted a lack of evidence from Terrenus to justify a commercial lending rate. Citing evidence of Attika’s fixed deposit rates, the court fixed the interest rate at a lower, more conservative figure, noting that "there is no evidence from Terrenus that payment would have reduced or obviated its need to borrow."
What Was the Outcome?
The High Court determined the appropriate commencement dates and interest rates for pre-judgment interest on damages awarded to both the plaintiff (Terrenus) and the defendant (Attika). The Court rejected the parties' proposed lending-based interest rates due to a lack of sufficient evidence, opting instead for rates based on established deposit evidence or reasonable proxies.
The Court ordered that pre-judgment interest on the nominal damages, diminution in value, and liquidated damages due to Terrenus shall run from 2 March 2022 at a rate of 0.18%. Regarding Attika's claim for the Balance Sum, the Court ordered interest to run from 2 April 2022 at a rate of 3.1%. Parties were directed to submit costs submissions within three weeks.
[285] ... s breach, should be and are dealt with under that claim. I therefore do not consider 11 March 2022 to be a relevant date. Following from the above, I order that pre- judgment interest on the nominal damages, diminution in value and liquidated damages due to Terrenus, is to run from 2 March 2022 till the date of this Judgment.
Why Does This Case Matter?
This case clarifies the court's approach to determining pre-judgment interest under s 12(1) of the Civil Law Act 1909, particularly where construction contracts lack specific payment dates or where parties fail to provide robust evidence of actual borrowing costs. The court affirmed that interest generally accrues from the date the loss is suffered or the entitlement arises, rather than the date the claim is formally brought.
The decision builds upon the principles established in Robertson Quay Investment Pte Ltd v Steen Consultants Pte Ltd and Grains and Industrial Products Trading Pte Ltd v Bank of India, reinforcing that claimants should be compensated for the time value of money. It distinguishes between the date of certification and the date of payment, providing a practical framework for calculating interest in the absence of contractual clarity.
For practitioners, this case serves as a cautionary tale regarding the evidentiary burden required to claim interest at commercial lending rates. Litigators must ensure that claims for interest are supported by specific, admissible evidence of borrowing costs; otherwise, the court will likely default to conservative rates, such as fixed deposit rates, which may significantly undervalue the actual cost of capital.
Practice Pointers
- Define 'Commissioning' with Precision: Avoid ambiguity in construction contracts by explicitly defining 'commissioning' and 'energisation' to include specific regulatory tests (e.g., PQ Tests under SS 638) rather than relying on generic industry terms.
- Document Control is Evidential Gold: The court prioritised the COPS documents as the definitive record of commissioning. Ensure that all project-related certifications are dated accurately and that any 'mistaken' filings are formally corrected and documented immediately to avoid evidentiary disputes.
- Proactive Evidence for Pre-judgment Interest: To claim interest at commercial lending rates, parties must provide concrete evidence of actual borrowing costs or the specific financial impact of the delay. In the absence of such evidence, the court will default to conservative deposit rates.
- Link Liquidated Damages to Specific Milestones: Ensure that the contract clearly distinguishes between 'Partial Completion' and 'Date of Completion' and that the criteria for each are tied to objective, verifiable milestones rather than subjective interpretations of 'energisation'.
- Anticipate Regulatory Compliance as a Contractual Condition: Where a contract requires compliance with codes of practice (e.g., SS 638), treat these as contractual obligations. Failure to perform mandatory tests (like the PQ Test) can invalidate the 'completion' status of the works.
- Manage EOT Requests Rigorously: The case highlights the importance of strict adherence to contractual EOT mechanisms (e.g., cl 5.5.4). Failure to follow the prescribed formal request process may preclude a contractor from claiming relief for delays.
Subsequent Treatment and Status
As a decision from late 2023, Terrenus Energy SL2 Pte Ltd v Attika Interior + MEP Pte Ltd is relatively recent. It has not yet been subject to significant appellate scrutiny or widespread judicial interpretation in subsequent reported Singapore High Court decisions.
The judgment largely reinforces established principles regarding the court's discretion in awarding pre-judgment interest under s 12(1) of the Civil Law Act, specifically the requirement for parties to substantiate claims for interest at commercial lending rates with actual evidence of borrowing costs. Its analysis of contractual completion milestones serves as a practical application of standard construction contract interpretation rather than a departure from existing precedent.
