Summary
This case concerned an application to set aside an adjudication determination under Singapore’s Building and Construction Industry Security of Payment Act (Cap 30B, 2006 Rev Ed) (“SOPA”). The applicant, Chuang Long Engineering Pte Ltd (“Chuang Long”), was the main contractor for a residential envelope control project. It terminated its subcontract with the respondent, Nan Huat Aluminium & Glass Pte Ltd (“Nan Huat”), and later resisted Nan Huat’s payment claim on the basis that certain materials were not delivered or installed. The adjudicator nonetheless included the value of those “uninstalled materials” in the adjudicated sum.
The High Court (Chan Seng Onn J) dismissed Chuang Long’s application. The sole issue was the proper interpretation of s 7(2)(c) SOPA—specifically, whether that provision limits valuation only to materials that have become the property of the party for whom the construction work is carried out (typically by affixation or incorporation), or whether it also permits valuation of materials that “on payment, will become the property” even if they have not yet been delivered or installed.
In holding that the adjudicator had jurisdiction, the court accepted a broader reading of s 7(2)(c) SOPA. It rejected the applicant’s “Property Passing Test” that would confine valuation to materials already incorporated or affixed. The court further held that s 7(2)(c) is not constrained by s 36(4) SOPA in the manner argued by Chuang Long, and that the statutory scheme is intended to facilitate cash flow for downstream parties in the construction industry.
What Were the Facts of This Case?
Chuang Long acted as the main contractor for a project described as the “Proposed new erection of a 2-storey envelope control detached dwelling house with an attic and a basement” (the “Project”). Under a subcontract agreement worth $323,282.50 (excluding GST), Chuang Long appointed Nan Huat as the subcontractor responsible for aluminium and glass-related works for the Project.
On 3 September 2018, Chuang Long terminated the subcontract, alleging breach of completion deadlines and schedule of works. Shortly thereafter, on 24 September 2018, Nan Huat filed a payment claim for unpaid works, claiming $237,421.35. Chuang Long served a payment response on 8 October 2018, but Nan Huat remained dissatisfied and referred the dispute to adjudication under SOP/AA 385/2018.
After considering the works completed and applying deductions for retention and previous payments, the adjudicator determined that $165,683.91 (inclusive of GST) was payable by Chuang Long to Nan Huat (the “Sum”). A key component of the Sum was an amount of $75,651.00 representing the value of “uninstalled materials” (the “uninstalled materials”). These materials had been fabricated by Nan Huat for the Project but had not been delivered nor installed by the time of adjudication.
The uninstalled materials comprised $45,831.00 for aluminium fins and $29,820.00 for cladding. The adjudicator reasoned that s 7(2)(c) SOPA permitted inclusion of the value of materials or components that were to form part of the building/structure arising from the construction work, and that, on payment, would become the property of the party for whom the construction work was being carried out. Chuang Long then applied to set aside the adjudication determination, contending that the adjudicator had exceeded jurisdiction by wrongly applying s 7(2)(c) SOPA to include the uninstalled materials.
What Were the Key Legal Issues?
The central legal issue was whether the adjudicator properly interpreted s 7(2)(c) SOPA when valuing materials that were fabricated for the Project but not delivered or installed. In other words, the court had to decide whether s 7(2)(c) confines valuation to materials that have already become the property of the party for whom the construction work is carried out, or whether it also allows valuation of materials that will become such property “on payment”.
Chuang Long advanced a narrower interpretation. It argued that the correct approach was a “Property Passing Test”, grounded in common law principles of property transfer. Under this approach, only materials that had been incorporated or affixed to the building (and thus would have passed in property) should be valued under s 7(2)(c) SOPA. Chuang Long further contended that the second limb of s 7(2)(c) (materials that “on payment, will become the property”) would only be relevant where the contract included a retention of title clause, such that property would not pass under common law until payment.
Nan Huat and the adjudicator adopted a broader approach. They treated s 7(2)(c) as permitting valuation in two scenarios: (a) where materials had already become the property of the party for whom the construction work was carried out (Situation A), and (b) where materials had not yet become the property but would do so once payment was made (Situation B). The dispute therefore turned on whether Situation B could extend to materials that were neither delivered nor installed, so long as they were fabricated to form part of the works.
How Did the Court Analyse the Issues?
Chan Seng Onn J began by framing the application as a jurisdictional challenge tied to statutory interpretation. The court emphasised that the sole issue was whether the adjudicator had properly interpreted s 7(2)(c) SOPA. This focus is significant in SOPA set-aside applications: while the court does not generally re-adjudicate the merits, it will intervene where the adjudicator’s determination is based on an incorrect interpretation of the statute such that jurisdiction is affected.
On the applicant’s interpretation, the court considered the “Property Passing Test” and the common law rule that property in materials and fittings typically passes upon incorporation or affixation to a building. Chuang Long relied on this common law position (as reflected in standard contract texts) to argue that s 7(2)(c) should be read as essentially mirroring affixation/incorporation. Under this view, the valuation should not include materials that remain uninstalled, because property would not have passed to the main contractor at that stage.
The court rejected this constrained reading. It agreed with the respondent’s and adjudicator’s interpretation that s 7(2)(c) SOPA is not limited to materials that have already been incorporated or affixed. Instead, the provision expressly contemplates two categories: materials that “have become” the property of the party for whom the construction work is carried out, and materials that “on payment, will become” such property. The statutory language therefore supports valuation beyond the strict affixation moment, provided the materials fall within the class of “materials or components that are to form part of any building, structure or works arising from the construction work”.
Crucially, the court accepted that the second limb (Situation B) can apply even where the materials have not been delivered or installed. The adjudicator’s reasoning was that the uninstalled materials were fabricated for the Project and were intended to form part of the building/structure. On that basis, the adjudicator treated them as within the valuation framework of s 7(2)(c). The court’s approach thus gave operative effect to the phrase “on payment, will become the property”, rather than treating it as a narrow exception only triggered by retention of title clauses.
Chuang Long also argued that this broader reading was inconsistent with Parliamentary intention, invoking s 36(4) SOPA. Section 36(4) provides that nothing in the Act (except as provided in s 36(1)) shall limit or otherwise affect the operation of other laws relating to rights, title, interests, or liabilities arising under or by virtue of a contract or agreement. The applicant’s submission was that Parliament intended s 7(2)(c) to incorporate the existing common law position on property passing, and therefore valuation should track affixation/incorporation.
The court did not accept that argument. It held that s 7(2)(c) SOPA is not constrained by s 36(4) SOPA in the manner proposed. In effect, s 36(4) preserves other laws on property rights and contractual title, but it does not prevent SOPA from prescribing how valuation is to be carried out for the limited purpose of adjudication. The court’s reasoning reflects the distinct function of SOPA: it is designed to provide a rapid interim mechanism for payment disputes in the construction sector, and the valuation provisions should be interpreted to support that objective.
Finally, the court considered the statutory purpose of facilitating cash flow for downstream players. By allowing valuation of materials fabricated for the works even if they are not yet installed, the SOPA scheme reduces the risk that subcontractors or suppliers are left uncompensated merely because delivery/installation has not occurred at the time of adjudication. This is particularly relevant where the main contractor terminates the subcontract and disputes arise over completion and payment. The court therefore concluded that the situation before it aligned with SOPA’s intention.
What Was the Outcome?
Chan Seng Onn J dismissed Chuang Long’s application to set aside the adjudication determination dated 30 November 2018 (amended and re-dated 18 December 2018). The court held that the adjudicator had properly interpreted s 7(2)(c) SOPA and therefore had jurisdiction to include the value of the uninstalled materials in the adjudicated sum.
Practically, the decision meant that the adjudicated sum of $165,683.91 (inclusive of GST), including the $75,651.00 component for aluminium fins and cladding that were fabricated but not delivered or installed, remained enforceable subject to the usual SOPA enforcement framework. The main contractor could not avoid payment by relying on a narrow property-passing approach tied to affixation/incorporation.
Why Does This Case Matter?
This decision is important for practitioners because it clarifies the scope of valuation under s 7(2)(c) SOPA. It confirms that adjudicators are not confined to valuing only materials that have been incorporated or affixed to the building. Instead, where materials are “to form part of” the building/structure arising from the construction work, their value may be included even if they have not been delivered or installed, provided the statutory conditions in s 7(2)(c) are satisfied.
For contractors and subcontractors, the case affects how payment claims should be framed and defended. Main contractors resisting claims for materials may find it difficult to exclude “uninstalled” components solely by invoking common law property passing rules. The decision also reduces the strategic value of termination-based disputes where fabricated materials remain unpaid but are intended for incorporation into the works.
From a precedent perspective, the case reinforces a purposive interpretation of SOPA that prioritises cash flow and the effectiveness of adjudication. It also illustrates how courts treat s 36(4) SOPA: while it preserves other laws on rights and title, it does not necessarily limit SOPA’s valuation methodology. Lawyers advising on construction contracts should therefore consider how contractual title clauses and delivery/installation provisions interact with SOPA’s adjudication valuation framework.
