Summary
This decision of the Appellate Division of the High Court arose from a subcontract dispute between Zhong Kai Construction Company Pte Ltd (“ZK”) and Diamond Glass Enterprise Pte Ltd (“DG”) concerning aluminium cladding and related façade works for the Singapore Changi Airport project. The subcontract was governed by a letter of award dated 7 November 2016. The works were divided into Phase 1 and Phase 2A, and the subcontract contained contractual provisions on completion dates and liquidated damages (“LD”) for delay. After DG allegedly abandoned the worksite in June 2018, ZK sought LD and replacement/rectification costs, while DG counterclaimed for sums due under variation orders, retention, and other amounts.
At first instance, the High Court judge allowed ZK’s LD claim in part (for Phase 1 but not Phase 2A), allowed replacement and rectification works in part, and dismissed ZK’s attempt to overturn the adjudicated amount awarded to DG under the Building and Construction Industry Security of Payment Act (Cap 30B, 2006 Rev Ed) (“SOPA”). Both parties appealed. The Appellate Division allowed DG’s appeal in part and ZK’s appeal in part. It reduced the LD awarded for Phase 1, set aside part of the award relating to replacement/rectification works, allowed ZK’s appeal for certain replacement/rectification items, and allowed DG’s counterclaims for certain variation orders and the retention sum. The court also remitted the question of DG’s entitlement to legal costs for the adjudication back to the judge for determination.
What Were the Facts of This Case?
ZK is a Singapore-incorporated company engaged in building and construction. DG is also Singapore-incorporated and operates in the architectural glass sector, including design, manufacture, supply, installation and maintenance. The underlying project concerned 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 as the consultant and SCB Building Construction Pte Ltd as the main contractor. ZK was a subcontractor under SCB, and ZK in turn engaged DG under the subcontract dated 7 November 2016.
Under the subcontract, DG was engaged to supply materials, equipment and tools and to carry out and complete aluminium cladding of an external façade, blast/ballistic doors and windows, aluminium doors, and window works. The subcontract sum was described as a provisional sum of $558,055 (excluding goods and services tax). Importantly for the dispute, the works were divided into Phase 1 and Phase 2A. Phase 1 related to works for an eight-storey Equipment Building, while Phase 2A related to works for a two-storey Annex Building. The court’s analysis of LD turned on how the subcontract’s completion dates applied to these phases.
According to ZK, DG began to show signs of delay as early as February 2017. ZK and the main contractor SCB issued written notices and reminders to DG over the period from February 2017 to February 2018. DG’s position was that the delays were not attributable to it. DG argued that delays were caused by ZK and/or parties further up the contractual chain, including ZK’s delay in obtaining requisite approval from the Building and Construction Authority (“BCA”) for structural works for Phase 1, changes in glass specifications, and ZK’s refusal to agree to payment of claims or to pay on time and in full.
The disagreement continued into 2018. The dispute eventually escalated to DG’s alleged abandonment of the worksite around 6 June 2018. ZK’s claims were not limited to LD. ZK also sought sums for replacement and rectification works said to be necessitated by DG’s abandonment and/or defective performance. In parallel, there was an adjudication under SOPA. ZK sought to overturn the adjudicated amount awarded to DG in an adjudication determination dated 15 November 2019 (“AD”). The High Court judge dismissed ZK’s attempt to overturn the adjudicated amount, and this formed part of the appellate landscape.
What Were the Key Legal Issues?
The Appellate Division identified several key issues. The first major cluster concerned ZK’s claim for liquidated damages. In particular, the court had to determine whether the completion dates in clause 6 or clause 4 of the subcontract applied to the relevant works. This matters because the contractual completion date determines when delay begins and ends for LD purposes.
Second, the court had to decide whether ZK should have been awarded LD for Phase 1 for the period following the termination of the subcontract. This required the court to consider the legal effect of termination and whether LD could continue to accrue after termination, especially where the contractor’s alleged repudiation/abandonment was in issue.
Third, the court had to examine whether there were events of delay caused by and/or attributable to DG. The judgment refers to “three purported periods of delay” and required the court to assess causation and attribution: even if there was overall delay, LD cannot be imposed for periods where the delay is caused by the employer or other non-contractual factors, or where the contractor is not responsible.
How Did the Court Analyse the Issues?
The Appellate Division’s reasoning proceeded by focusing on the contractual architecture of the subcontract and the evidential basis for delay and termination. On the LD question, the court treated the subcontract’s completion date provisions as central. The parties disputed whether clause 6 or clause 4 governed the completion dates relevant to the LD calculation. The court’s approach reflects a standard contractual interpretation method: the court read the subcontract as a whole, giving effect to the parties’ intended allocation of time and responsibility for completion. The outcome of this interpretive exercise directly affected the LD computation and the start/end points for delay.
Having addressed the completion date clause, the court then considered whether LD should be awarded for Phase 1 for the period following termination. This required the court to engage with the legal consequences of termination, including whether termination was a response to the contractor’s repudiation and abandonment and what that means for the employer’s entitlement to liquidated damages. The court’s analysis also had to reconcile the LD mechanism with the practical reality that once a subcontract is terminated, the employer’s remedies shift towards replacement and recovery of losses, rather than continuing to claim LD as if the contractor had remained responsible for completion.
The court also analysed causation and attribution of delay. LD clauses typically operate on the assumption that delay is attributable to the contractor. The court therefore examined the “three purported periods of delay” relied upon by ZK and assessed whether these periods were actually caused by DG’s performance failures, or whether they were attributable to ZK (or upstream parties) such as approval delays, specification changes, or payment disputes. This is a critical aspect of construction disputes: even where there is a contractual LD clause, the employer must still establish that the relevant delay is within the contractor’s responsibility. The court’s decision to reduce LD for Phase 1 indicates that at least some of the claimed delay periods were not properly attributable to DG or were not captured correctly by the contractual completion date framework.
Beyond LD, the Appellate Division addressed DG’s counterclaims and ZK’s claims for replacement and rectification works. The High Court had allowed some replacement/rectification items and disallowed others. On appeal, the Appellate Division set aside part of the award in DG’s favour and allowed ZK’s appeal for certain sums (including an award of $27,735.47 for replacement and rectification works). This demonstrates that the appellate court scrutinised the itemised basis for each claim, rather than treating the replacement/rectification head as a single global sum. The court’s willingness to adjust specific items suggests that evidential support, scope of works, and causation were decisive at the granular level.
Finally, the court dealt with the SOPA adjudication dimension. ZK had sought to overturn the adjudicated amount awarded to DG. The High Court judge dismissed that attempt. On appeal, the Appellate Division did not disturb the dismissal of ZK’s attempt to overturn the adjudicated amount (as reflected in the summary of outcomes). However, the court did remit the question of DG’s entitlement to legal costs for the adjudication and the quantum back to the judge. This indicates that while the adjudication determination’s substantive amount was not overturned, the court still required further determination on the costs aspect, likely because the legal basis and/or quantum for adjudication costs needed careful assessment.
What Was the Outcome?
The Appellate Division allowed DG’s appeal in CA 125 in part and ZK’s appeal in CA 129 in part. For LD, DG’s appeal against the LD awarded to ZK was allowed in part: the $356,400 LD awarded for Phase 1 works was reduced by $165,600 to $190,800. DG also succeeded in having set aside an award of $5,906.40 to ZK for replacement and rectification works (item 1(e) at [93]). Conversely, ZK succeeded in its appeal against the dismissal of its claim for $27,735.47 for replacement and rectification works (item 4(a) at [93]).
On DG’s counterclaims, the Appellate Division allowed DG’s appeals for payments due under certain variation orders and for the retention sum. Specifically, DG was awarded $32,602.50 for VO 6, $13,185 for VO 8, and $27,902.75 for the retention sum. The court also remitted the question of DG’s entitlement to legal costs for the adjudication (and the quantum) back to the judge for determination. Given the mutual sums owing, the court ordered consequential set-off and related directions in the context of winding up proceedings, including dealing with a security sum paid into court by ZK to stay winding up pending the outcome of the appeals.
Why Does This Case Matter?
This case is significant for practitioners because it illustrates how appellate courts in Singapore approach LD disputes in construction contracts, particularly where the subcontract contains multiple completion date provisions and where the works are divided into phases. The reduction of LD for Phase 1 underscores that even where a contractual LD clause exists, the employer must still establish the correct contractual completion framework and causation for the delay periods relied upon. It also highlights that termination and abandonment can affect the temporal scope of LD entitlement.
From a remedies perspective, the decision is also useful for understanding the interplay between LD claims and replacement/rectification claims. The Appellate Division’s adjustments to specific itemised sums show that courts will not simply accept global claims; they will scrutinise whether the replacement/rectification works were within scope, were necessitated by the contractor’s breach, and were properly evidenced. This is particularly relevant in façade and specialist works where defects and delays can stem from multiple sources, including design/specification changes and approvals.
Finally, the SOPA dimension provides practical guidance. While the court did not overturn the adjudicated amount, it remitted the question of adjudication legal costs. This indicates that costs issues may remain open even where the substantive adjudicated sum is not disturbed. For contractors and subcontractors, the case therefore reinforces the importance of carefully framing both substantive and costs arguments in SOPA-related litigation, and of maintaining a clear evidential record for each head of claim.
