Summary
In Chuang Long Engineering Pte Ltd v Nan Huat Aluminium & Glass Pte Ltd [2019] SGHC 55, the High Court dismissed an application to set aside an adjudication determination under Singapore’s Building and Construction Industry Security of Payment Act (SOPA). The dispute turned on the proper interpretation of s 7(2)(c) SOPA, which governs how construction work and supplied goods are to be valued when the contract is silent on valuation.
The applicant main contractor argued for a “property passing” approach: only materials that had become the property of the party for whom the work was being carried out (typically by incorporation/affixation under common law) should be valued. The respondent sub-contractor, and the adjudicator, adopted a broader reading: s 7(2)(c) permits valuation not only of materials that have already become the relevant party’s property, but also of materials that on payment will become that party’s property—allowing valuation of certain fabricated but undelivered or uninstalled materials.
Chan Seng Onn J held that the adjudicator had properly interpreted s 7(2)(c) SOPA. The court rejected the applicant’s constrained interpretation and found that the broader “Situation B” approach better aligned with SOPA’s legislative purpose of preserving cash flow for downstream parties in the construction industry.
What Were the Facts of This Case?
The applicant, Chuang Long Engineering Pte Ltd (“Chuang Long”), was 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”). Chuang Long engaged the respondent, Nan Huat Aluminium & Glass Pte Ltd (“Nan Huat”), as a sub-contractor under a subcontract agreement valued at $323,282.50 (excluding GST).
On 3 September 2018, Chuang Long terminated the subcontract, alleging breach of completion deadlines and the schedule of works. Shortly thereafter, on 24 September 2018, Nan Huat filed a payment claim for unpaid works, seeking $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.
The adjudicator considered the works completed by Nan Huat and made deductions for retention sums and previous payments. The adjudicator ultimately 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 uninstalled materials were aluminium fins and cladding that had been fabricated for the Project but had not been delivered nor installed by Nan Huat at the time of adjudication. The adjudicator valued the uninstalled materials at $45,831.00 (aluminium fins) and $29,820.00 (cladding). The adjudicator reasoned that s 7(2)(c) SOPA entitled him, for the valuation exercise, to include materials or components that were to form part of the building/structure and that, on payment, would become the property of the party for whom the construction work was being carried out.
What Were the Key Legal Issues?
The sole issue before the High Court was whether the adjudicator had properly interpreted s 7(2)(c) SOPA when valuing the uninstalled materials. In other words, the court had to decide whether s 7(2)(c) restricts valuation to materials that have already become the property of the paying party (Chuang Long), or whether it also extends to materials that will become such property on payment.
More specifically, the applicant contended that the correct approach was a “Property Passing Test”: valuation under s 7(2)(c) should track the passing of property under common law principles. Under this approach, only materials incorporated or affixed to the building (and therefore already owned by the main contractor) should be valued. The applicant argued that the adjudicator’s inclusion of undelivered and uninstalled materials went beyond what Parliament intended.
By contrast, Nan Huat and the adjudicator treated s 7(2)(c) as creating two valuation scenarios. The first scenario covers materials that have already become the property of the party for whom the construction work is being carried out. The second scenario covers materials that have not yet become the property but will do so once payment is made. The legal question was whether the second scenario is permissible under the statutory text and legislative purpose.
How Did the Court Analyse the Issues?
Chan Seng Onn J began by setting out the statutory framework. Section 7(1) SOPA requires construction work carried out or goods supplied under a contract to be valued in accordance with the contract terms; if the contract does not contain such provision, the valuation must have regard to matters specified in s 7(2). Here, it was agreed that the contract was silent on valuation, so s 7(2) applied.
The judge then focused on the wording of s 7(2)(c). The provision allows valuation, in the case of materials or components that are to form part of any building, structure or works arising from the construction work, having regard to the basis that “the only materials or components to be included in the valuation are those that have become or, on payment, will become the property of the party for whom the construction work is being carried out.” The judge emphasised that the provision is not merely about incorporation; it expressly contemplates materials that will become the relevant party’s property upon payment.
In analysing the competing interpretations, the court considered the applicant’s argument that the phrase “have become or, on payment, will become the property” should be read through common law property passing rules. The applicant relied on the general common law position described in Hudson’s Building and Engineering Contracts that property in materials and fittings passes once incorporated or affixed to a building. Under the applicant’s approach, s 7(2)(c) would effectively be confined to materials already incorporated/affixed, with the “on payment” language only relevant where contractual retention of title clauses delay property passing until payment.
The respondent’s approach, which the adjudicator adopted, was broader. The judge accepted that s 7(2)(c) can be understood as permitting valuation in two situations: (A) where materials have already become the property of the paying party; and (B) where materials have not yet become the property but will become it once payment is made. Importantly, the respondent’s “Situation B” did not require delivery or installation; it was sufficient that the materials were fabricated for the contract and were intended to form part of the building/structure.
The applicant further argued that “Situation B” was inconsistent with Parliamentary intention because it would undermine the common law position on property passing and would “drastically affect” the law relating to passing of property. The applicant invoked s 36(4) SOPA, which provides that nothing in the Act shall, except as provided in s 36(1), limit or otherwise affect the operation of other law 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 SOPA to preserve the existing common law property passing regime, and therefore s 7(2)(c) should not be read to extend valuation beyond incorporation/affixation.
Chan Seng Onn J rejected this. First, the judge explained that s 36(4) must be read in context with s 36(1). Section 36(1) prohibits parties from contracting out of SOPA’s regime, including the payee’s right to progress payments and adjudication. Section 36(4) operates as a qualifier: it ensures that SOPA does not reconfigure or alter the effect of underlying contract terms except where SOPA’s regime is excluded, modified, restricted, or prejudiced. Accordingly, s 36(4) did not dictate that s 7(2)(c) must be interpreted narrowly to mirror common law property passing.
More crucially, the judge found that the respondent’s interpretation better accorded with SOPA’s overriding purpose. SOPA is designed to preserve cash flow for parties in the construction industry by ensuring that payment disputes are resolved expeditiously through adjudication, without requiring final determination of complex contractual and property-law issues. A narrow reading that limits valuation only to materials already incorporated or affixed would, in practice, frustrate that purpose where fabricated materials are ready for incorporation but have not yet been installed due to disputes, termination, or other practical circumstances.
In this case, the adjudicator had included the value of uninstalled materials because they were fabricated for the Project and were intended to form part of the building/structure. The court accepted that s 7(2)(c) permits such valuation under the “on payment” limb, provided the statutory conditions are satisfied. The judge therefore concluded that the adjudicator had not exceeded jurisdiction or misapplied the statutory provision in a manner warranting setting aside the adjudication determination.
What Was the Outcome?
The High Court dismissed Chuang Long’s application to set aside the adjudication determination dated 30 November 2018 (amended and re-dated 18 December 2018). The practical effect was that Nan Huat’s adjudicated entitlement, including the component for the uninstalled materials valued under s 7(2)(c), remained enforceable pending any further proceedings.
By upholding the adjudicator’s interpretation, the decision confirmed that SOPA adjudication can include valuation of certain fabricated but undelivered or uninstalled materials, where those materials are intended to form part of the relevant building/structure and where the statutory “on payment” property basis is satisfied.
Why Does This Case Matter?
This case is significant for practitioners because it clarifies how s 7(2)(c) SOPA should be interpreted in valuation disputes. The decision rejects an overly restrictive reading that ties valuation solely to common law property passing through affixation or incorporation. Instead, it recognises that the statutory text expressly contemplates materials that will become the relevant party’s property on payment, and that this can extend valuation beyond installed materials.
For main contractors, the case highlights the risk that termination or disputes about progress may not prevent adjudicators from valuing fabricated materials intended for the project, even if those materials have not been delivered or installed. For subcontractors and suppliers, the decision supports the ability to claim adjudicated sums for materials fabricated for the works, thereby strengthening SOPA’s cash-flow function and reducing the need to await final resolution of complex property-law questions.
From a precedent perspective, Chuang Long provides useful guidance on the relationship between SOPA’s valuation provisions and s 36(4). It demonstrates that s 36(4) does not automatically import common law constraints into the interpretation of specific SOPA provisions. Instead, courts will interpret SOPA provisions purposively to achieve the statutory objective of timely payment through adjudication.
