Summary
This case concerns whether parties had formed a binding contract for the design, supply and installation of a temporary steel ramp (“Ramp Works”) for a Marina Bay Sands project. The appellant, a subcontractor specialising in theatre engineering and steel structural works, proceeded to fabricate materials after it believed the respondent had accepted its quotation. The respondent later rejected the materials and instructed the appellant to stop further work, contending that no agreement had been reached.
The District Judge (DJ) had found that there was no agreement and ordered the return of the adjudicated sum on the basis of unjust enrichment. On appeal, Choo Han Teck J held that, on the totality of the parties’ communications and conduct, an agreement for the Ramp Works had been reached and that the respondent had instructed the appellant to proceed. The High Court therefore reversed the DJ’s conclusion on contract formation.
What Were the Facts of This Case?
The respondent, Pure Group (Singapore) Pte Ltd, managed a project at Marina Bay Sands (“MBS”) involving the conversion of a theatre into a restaurant and nightclub. The respondent’s general manager, Jonathan Peter Coney (“Mr Coney”), led the project team. He was assisted by Thomas Tan Boon Chin (“Mr Tan”), a senior project manager seconded from the respondent’s Malaysian office.
The appellant, Siong Ann Engineering Pte Ltd, was one of the subcontractors engaged for various works under multiple sub-contracts for the project. The dispute in this appeal related only to the Ramp Works: the design, supply and installation of a temporary ramp to transport materials from the theatre entrance to the stage area. The appellant’s case was that the respondent accepted its quotation for the Ramp Works and thereby authorised the appellant to fabricate and deliver the steel components to the worksite. The respondent’s position was that no agreement had been reached, and it therefore rejected the materials and told the appellant not to proceed further.
On 16 January 2018, the respondent asked the appellant to submit a quotation for the Ramp Works. Mr Tan informed Mr Wong (the appellant’s business and development manager) that the ramp was needed urgently. That same day, the appellant emailed a quotation for $100,000 (“the 16 January Quotation”). Between 17 January and 1 February 2018, the parties discussed technical designs and specifications and revised requirements were made. The appellant then submitted a revised quotation for $130,180 (“the 1 February Quotation”).
On 3 February 2018, Mr Tan informed the appellant that the respondent wanted the temporary steel ramp completed by 16 February 2018 and requested further details by 5 February 2018. The appellant provided the requested details. On 5 February 2018, the respondent’s Senior Project Director, Chris Potts (“Mr Potts”), asked for further particulars such as description of works, quantity, and unit rates. The appellant provided these in a quotation dated 5 February 2018 (“the 5 February Quotation”). The scope of work, price and other terms in the 5 February Quotation essentially mirrored the 1 February Quotation.
On 7 February 2018, Mr Wong messaged Mr Coney via WhatsApp asking when the appellant could commence the Ramp Works. Mr Coney told Mr Wong to discuss the matter with Mr Tan, but Mr Wong responded that Mr Tan’s authority was limited and that Mr Coney’s approval was needed to start. Mr Coney then said he would go through the costs internally with Mr Tan and that the appellant would receive instructions that night.
On 8 February 2018, at 9.20am, Mr Tan emailed Mr Wong stating: “Pls have the steel materials ready for your fabrication-installed by 23 Feb 2018, thanks.” Mr Wong immediately acknowledged receipt and indicated that the appellant would start preparing the steelworks materials for site installation. On 9 February 2018, the parties exchanged WhatsApp messages. Mr Wong informed Mr Coney that the appellant had begun fabricating steelworks materials for the ramp and would assemble and install after certain theatre works were completed. Mr Coney responded that Mr Wong should not proceed with works not approved, and specifically asked for understanding of materials used, while stating that the ramp should proceed but that they wanted to discuss the cost. Mr Wong replied that the appellant had started the ramp works (and not other hoarding works). Mr Coney replied “Yes the one at stage area is ok.”
On 19 February 2018, Mr Wong told Mr Coney that the appellant had ready some steelworks for the ramp and asked whether the respondent could issue a purchase order (“PO”). Mr Coney replied that it could be done the next day and asked whether Mr Wong would be around at MBS. However, on 22 February 2021 (as reflected in the extract), Mr Coney emailed Mr Wong instructing him not to do any further work on the ramp until they discussed the works. The instruction to stop was made after the respondent’s structural engineer, Arup Singapore Pte Ltd (“Arup”), expressed concerns about calculations of the load capacity of the steel ramp. The parties attempted to resolve the issue but could not.
The appellant then filed an adjudication application seeking payment for the Ramp Works. The adjudicator determined that $123,897.77 was payable, and the respondent paid the adjudicated sum (“the Paid Sum”). The respondent subsequently commenced suit in the District Court to recover the Paid Sum, arguing that there was no agreement and that the appellant had been unjustly enriched.
What Were the Key Legal Issues?
The central legal issue was whether a contract for the Ramp Works had been formed between the parties. Contract formation in this context turned on whether there was an offer and acceptance that resulted in a binding agreement, and whether the parties had reached consensus on essential terms—particularly price and scope.
A related issue was whether the communications relied upon by the appellant could amount to acceptance or instruction to proceed. The District Judge had found, among other things, that Mr Tan did not have actual, implied or apparent authority to approve the Ramp Works, and that there was no unqualified expression of agreement. The High Court therefore had to consider how to characterise the respondent’s emails and WhatsApp messages, and whether the respondent’s conduct amounted to acceptance of the appellant’s quotation.
Finally, the appeal also required the High Court to address the interaction between the parties’ communications and the respondent’s later attempt to stop work. Even if technical concerns arose later (such as Arup’s load calculations), the legal question remained whether the parties had already formed a contract earlier such that the appellant’s fabrication and delivery were authorised.
How Did the Court Analyse the Issues?
Choo Han Teck J approached the question of contract formation by examining the parties’ communications as a whole, rather than isolating individual messages. The judge accepted that the respondent’s instruction in the 8 February Email was pivotal. In that email, Mr Tan asked the appellant to have the steel materials ready for fabrication-installed by 23 February 2018. The respondent argued that the phrase “have the steel materials ready for your fabrication-installed” did not mean “fabricate now”. The High Court, however, treated the email as clear instruction to commence work to meet the tight timeline, particularly because the same email contemplated installation by a specific date.
The judge also considered the respondent’s argument that Mr Tan lacked authority to enter into contracts on the respondent’s behalf. The High Court’s reasoning was that authority was not the decisive factor on the facts as presented. The instructions to proceed were not limited to Mr Tan’s email; they were supported by the broader context, including Mr Coney’s prior WhatsApp message on 7 February. On 7 February, Mr Coney had told Mr Wong that he would go through costs internally with Mr Tan and that the appellant would receive instructions that night. The next morning, Mr Tan’s email could reasonably be understood as a follow-up to that internal cost discussion and as an operational instruction to proceed.
In other words, the High Court treated the communications as reflecting a consensus process: Mr Wong sought approval to commence, Mr Coney indicated that he would consider costs internally and would issue instructions, and then the appellant received an email instructing it to prepare materials for fabrication and installation by a deadline. The judge found that a reasonable reader would conclude that Mr Coney had discussed the price overnight with Mr Tan and had no objection to the appellant commencing the Ramp Works.
Second, the judge analysed the parties’ subsequent conduct and communications, focusing on the 9 February WhatsApp exchange. Mr Wong told Mr Coney that the appellant had begun fabricating the steelworks materials and would assemble and install after other theatre works were completed. Mr Coney’s response was not an instruction to stop the ramp fabrication; rather, he said not to proceed with works not approved and asked for understanding of materials used, while stating that the ramp should proceed but they wanted to discuss the cost. Mr Wong then clarified that the appellant had started the ramp works and that other hoarding works had not been started. Mr Coney responded affirmatively: “Yes the one at stage area is ok.”
The High Court treated this as evidence of acceptance and authorisation. The absence of an objection to the appellant’s commencement of fabrication, despite being explicitly informed, suggested that the respondent had accepted the Ramp Works at least in principle and had allowed the appellant to proceed. The judge also addressed the respondent’s attempt to characterise Mr Coney’s “however want to discuss the cost” as a qualification that prevented agreement on price. The High Court disagreed, reasoning that even after the appellant repeatedly informed the respondent that it had commenced work, the respondent did not raise objections about costs. The judge emphasised that silence ordinarily is not consent, but in this case the respondent’s failure to object to costs, coupled with express acceptance of the ramp works proceeding, supported the inference that the parties had reached agreement.
Third, the judge considered the 19 February WhatsApp exchange. Mr Wong asked whether the respondent could receive a purchase order because some steelworks were ready. Mr Coney replied that it could be done the next day and asked whether Mr Wong would be around at MBS. This further supported the appellant’s understanding that the respondent was proceeding with the Ramp Works and was moving towards formalisation through a PO.
Although the extract truncates the remainder of the judgment, the reasoning visible in the provided portion indicates that the High Court’s approach was grounded in the objective theory of contract formation: what the parties’ words and conduct would reasonably convey to each other. The High Court’s conclusion that there was an agreement was therefore based on (i) the respondent’s instruction to prepare materials for fabrication and installation by a deadline, (ii) the subsequent WhatsApp exchanges showing the ramp works were proceeding with the respondent’s knowledge, and (iii) the respondent’s failure to object to costs when the appellant’s commencement was expressly communicated.
What Was the Outcome?
The High Court held that there was an agreement between the parties for the Ramp Works and that the respondent had instructed the appellant to proceed. This reversed the District Judge’s finding that there was no agreement and that the Paid Sum should be returned on unjust enrichment grounds.
Practically, the effect of the High Court’s decision is that the appellant’s entitlement to the adjudicated sum (and the underlying contractual basis for the Ramp Works) was restored, subject to the procedural posture of the appeal and any consequential orders on costs and further relief.
Why Does This Case Matter?
This decision is significant for practitioners because it illustrates how Singapore courts determine contract formation in commercial settings where parties communicate through emails and informal messaging platforms such as WhatsApp. The case demonstrates that courts will look beyond formalities like purchase orders or site instructions, and will instead focus on whether the parties’ communications and conduct objectively show offer and acceptance.
For subcontracting and construction projects, the case also highlights a recurring practical issue: whether an instruction to proceed (especially one tied to deadlines) amounts to contractual acceptance even where price discussions are ongoing. The High Court’s reasoning suggests that where the respondent allows work to commence after being informed, and does not object to price at the relevant times, the court may infer agreement on essential terms. This is particularly relevant where the subcontractor has already mobilised resources and fabricated materials in reliance on the employer’s or main contractor’s communications.
Finally, the case is useful for understanding the limits of arguments about authority. While authority can be relevant in agency contexts, the High Court treated the broader communication context as decisive. Practitioners should therefore ensure that internal approval processes and delegation of authority are aligned with external communications, because courts may infer acceptance from the employer’s operational instructions and subsequent acquiescence.
