Summary
Zhong Kai Construction Co Pte Ltd v Diamond Glass Enterprise Pte Ltd concerned a subcontract for aluminium cladding and related architectural glass and door/window works at Singapore Changi Airport. The dispute arose from alleged delay, defective or incomplete works, and the subcontractor’s abandonment of the worksite in June 2018. The High Court also addressed the interplay between the parties’ substantive claims and the statutory adjudication regime under Singapore’s Building and Construction Industry Security of Payment Act (SOPA), including whether the adjudicated amount should be overturned.
In the High Court, Kwek Mean Luck JC allowed the plaintiff subcontractor’s claims for liquidated damages (LD) for delay, and allowed in part the costs of replacement and rectification works necessitated by the defendant’s abandonment. The court set aside three variation orders (VOs) that had been the subject of the SOPA adjudication determination, while allowing one VO claim and dismissing the defendant’s other claims. The court’s approach illustrates how SOPA adjudication determinations may be challenged in subsequent proceedings, but also how courts will scrutinise contractual scope, variations, and causation when assessing damages and the consequences of repudiation.
What Were the Facts of This Case?
The plaintiff, Zhong Kai Construction Co Pte Ltd (“Zhong Kai”), is a Singapore-incorporated company in the building and construction industry. The defendant, Diamond Glass Enterprise Pte Ltd (“Diamond Glass”), is also Singapore-incorporated and is engaged in the design, manufacture, supply, installation and maintenance of architectural glass. The underlying project was the construction of equipment buildings and facilities at Singapore Changi Airport. The owner was the Civil Aviation Authority of Singapore (CAAS), with Surbana Jurong Infrastructure Pte Ltd acting as consultant and SCB Building Construction Pte Ltd as the main contractor.
Zhong Kai acted as a subcontractor to SCB. By a letter dated 7 November 2016, Zhong Kai engaged Diamond Glass under a subcontract (the “Subcontract”) for the supply of materials, equipment and tools to carry out and complete specified works for the external facade, blast/ballistic doors and windows, aluminium doors, and window works. The Subcontract Sum was a provisional sum of $558,055 (excluding GST). The Subcontract was divided into two phases: Phase 1 for an eight-storey Equipment Building and Phase 2A for a two-storey Annex Building.
According to Zhong Kai, Diamond Glass began showing signs of delay in meeting the schedule as early as February 2017. Zhong Kai and SCB issued many written notices and reminders to Diamond Glass from February 2017 to February 2018. Diamond Glass, however, maintained that the delays were not caused by it. Diamond Glass attributed delay to Zhong Kai and/or parties further up the contractual chain, including Zhong Kai’s delay in obtaining approvals from the Building and Construction Authority (BCA) for structural works for Phase 1, changes in glass specifications, and Zhong Kai’s alleged refusal to agree to payment claims or to make payment on time and in full.
The dispute crystallised in 2018 through email correspondence concerning the purchase and installation of “cabin glass” required for the eight-storey Equipment Building under Phase 1. SCB’s email dated 17 April 2018 stated that despite repeated reminders, no order had been placed and there was no progress update. On 25 April 2018, Diamond Glass emailed Zhong Kai a letter titled “Cancellation of Purchase Order for Cabin Glass”, stating that it had not received substantive reply despite explanations of facts and issues regarding payment, and that it had “no choice but to cancel” the purchase order with immediate effect. Diamond Glass sought written confirmation that Zhong Kai would bear liability to pay $48,380 to settle Diamond Glass’s claims, without which Diamond Glass would not proceed further.
Zhong Kai responded the same day, warning that cancelling the purchase order would seriously impact overall completion. Zhong Kai indicated it would purchase the cabin glass and deduct the cost from Diamond Glass’s progress payment claim. On 30 May 2018, Diamond Glass replied, asserting that there was no delay by Diamond Glass from the moment glass specifications were changed, and emphasising that despite progress claims, no payment had been made on an outstanding sum of $261,006.74. Diamond Glass demanded payment of $149,436.99 by 12.00pm on 5 June 2018, warning that if payment was not made, it would treat the contract as terminated. Zhong Kai did not make the demanded payment by the deadline. On 6 June 2018, Diamond Glass abandoned the worksite.
Following abandonment, the parties exchanged emails regarding calculations of sums allegedly due. On 29 June 2018, Diamond Glass wrote that it had “no choice but to accept [Zhong Kai’s] repudiatory breach and terminate the contract” due to lack of full payment, unsigned variation quotations, and other matters. Diamond Glass also indicated a conditional willingness to complete the works if Zhong Kai provided assurance of full payment upon completion and paid $50,000 upfront. Zhong Kai replied on 30 June 2018, disputing the figures as untrue and misleading, and stating it had no choice but to engage third parties to complete remaining works and remedy defects on Diamond Glass’s behalf, with Diamond Glass responsible for consequences.
What Were the Key Legal Issues?
The case raised several interlocking legal issues. First, the court had to determine whether Diamond Glass’s delay and/or abandonment gave rise to Zhong Kai’s entitlement to liquidated damages under the Subcontract. This required analysis of contractual time obligations, the causes of delay, and whether Diamond Glass’s conduct justified the imposition of LD.
Second, the court had to assess the scope of works and variations. Diamond Glass’s claims included variation orders (VOs). Zhong Kai’s position was that certain works claimed as variations were either within the original scope or were not properly substantiated. The court therefore had to decide which VOs should stand and which should be set aside, including in the context of the SOPA adjudication determination.
Third, the court had to address the effect of SOPA adjudication. Zhong Kai sought to overturn the adjudicated amount awarded to Diamond Glass in an adjudication determination. The legal question was not merely whether the adjudicated amount was factually correct, but how the court should treat the adjudication outcome when the parties later litigate substantive rights, including the extent to which the adjudicated amount could be displaced and what findings should be made on the underlying contractual entitlements.
How Did the Court Analyse the Issues?
At the heart of the LD and damages analysis was causation: whether the delays were attributable to Diamond Glass and whether the Subcontract’s contractual mechanisms supported Zhong Kai’s claim for LD. The court considered the chronology of notices and reminders from February 2017 onwards, and the evidence of ongoing disputes about progress and payment. While Diamond Glass argued that delays were caused by Zhong Kai’s upstream approvals and specification changes, the court’s reasoning (as reflected in the outcome) indicates that it accepted Zhong Kai’s case to a significant extent that Diamond Glass was responsible for delay and that the contractual time obligations were not met.
The court also had to evaluate the legal significance of Diamond Glass’s abandonment of the worksite on 6 June 2018. Abandonment is often treated as a repudiatory breach, but the analysis depends on whether the abandoning party was itself in breach and whether the other party’s conduct amounted to repudiation. Here, Diamond Glass framed its abandonment as acceptance of Zhong Kai’s repudiatory breach due to non-payment and other alleged contractual failures. Zhong Kai, by contrast, treated Diamond Glass’s conduct as wrongful and proceeded to engage third parties to complete and rectify. The court’s decision to allow Zhong Kai’s claims for replacement and rectification works in part suggests that the court found Diamond Glass’s abandonment unjustified and causally linked to the costs incurred.
On variations and the scope of works, the court scrutinised the VO claims that were the subject of the SOPA adjudication. The Subcontract’s scope and the parties’ documentation mattered. The court set aside three VOs that had been awarded in the adjudication determination, while allowing one VO claim. This outcome indicates a careful, item-by-item approach rather than a wholesale acceptance or rejection of the adjudicator’s findings. In practical terms, the court treated the variation mechanism as requiring proper substantiation and alignment with the contractual scope, and it was not persuaded that all claimed variations were properly characterised or supported.
Regarding SOPA, the court’s analysis reflected the statutory design of SOPA adjudication: adjudication is intended to provide cashflow relief through a speedy determination, but it does not finally determine substantive rights. Parties may still litigate after adjudication, and courts may set aside or displace adjudicated amounts depending on the substantive merits and the legal grounds available. In this case, Zhong Kai sought to overturn the adjudicated amount. The court’s orders—allowing LD and certain replacement/rectification costs, setting aside most of the VO-related adjudicated components, and dismissing some of Diamond Glass’s claims—demonstrate that the court was willing to adjust the parties’ substantive entitlements away from the adjudication outcome where the evidence and contractual interpretation supported Zhong Kai’s position.
Finally, the court had to reconcile the parties’ procedural history with the substantive dispute. The extract indicates that earlier proceedings involved enforcement of the adjudication determination as a judgment debt and winding up steps, with the Court of Appeal upholding a stay of winding up pending the disposal of the consolidated suit. While those procedural matters are not the focus of the High Court’s final merits decision, they contextualise why the substantive litigation mattered: the court’s findings would determine the parties’ real financial positions beyond the interim SOPA adjudication.
What Was the Outcome?
The High Court allowed Zhong Kai’s claims for liquidated damages for delay and allowed the costs of replacement and rectification works in part. The court set aside three of the variation orders that had been the subject of the SOPA adjudication determination, thereby reducing Diamond Glass’s entitlement as reflected in the adjudicated outcome.
In addition, the court allowed one of Diamond Glass’s VO claims and dismissed Diamond Glass’s other claims. The practical effect of the orders is that Zhong Kai obtained relief both on damages and on the displacement of key components of the adjudicated amount, while Diamond Glass retained only limited success on one variation item.
Why Does This Case Matter?
This decision is significant for practitioners because it demonstrates how SOPA adjudication outcomes may be revisited in subsequent litigation, particularly where the dispute turns on contractual scope, the validity of variation claims, and the factual basis for delay and abandonment. While SOPA is designed for speed and interim payment, the case underscores that adjudication does not immunise a party from later findings on substantive entitlement.
For construction lawyers, the case is also useful as an illustration of how courts approach repudiation/abandonment narratives in subcontract disputes. The factual record—emails demanding payment, warnings of termination, and the subsequent abandonment—shows the evidential importance of contemporaneous correspondence. The court’s willingness to award LD and replacement/rectification costs in part suggests that where a subcontractor abandons work, the court will examine whether the abandonment was justified and whether the other party’s response (engaging third parties to complete and rectify) was reasonable and causally connected to the breach.
From a drafting and claims-management perspective, the case highlights the need for clear variation procedures and documentation. The partial setting aside of VOs indicates that not all claimed variations will survive judicial scrutiny, especially where a party characterises work as “variation” that may fall within the original scope or where the evidential basis for the VO is weak. Practitioners should therefore ensure that variation quotations, approvals, and supporting records are properly maintained and aligned with the contract’s variation regime.
