Summary
Poh Cheng Chew v K P Koh & Partners Pte Ltd and another concerned a construction dispute that was resolved through a settlement agreement requiring “expert determination” by a professional engineer appointed to design and manage rectification works. The dispute arose from additions and alterations (“A&A Works”) to a property at Sentosa Cove. After defects and alleged discrepancies were identified, the parties mediated and agreed that a professional engineer would (i) set the scope and specifications of rectification works, (ii) prepare tender documents, (iii) call for tenders, (iv) evaluate tenders, and (v) award the rectification contract.
The plaintiff later sued when the appointed engineer awarded the rectification contract to a higher bidder (Crystallite) and the defendants refused to make further payments under the settlement agreement. The defendants sought to set aside the engineer’s appointment and the award, arguing that the engineer was not independent, was influenced by the plaintiff and/or his agents, and materially departed from his instructions. The defendants also alleged conspiracy to fix fees and manipulate the tender outcome.
The High Court (Lionel Yee JC) addressed the legal framework for challenging an expert determination process embedded in a settlement agreement, including the threshold for setting aside an expert’s decision and the evidential burden for allegations of lack of independence, breach of instructions, and conspiracy. The court’s reasoning emphasised contractual construction, the nature of the expert’s mandate, and the need for clear proof when parties seek to unwind a settlement mechanism that was intended to bring finality and reduce litigation.
What Were the Facts of This Case?
The plaintiff, Poh Cheng Chew, engaged the defendants in 2010 for additions and alterations to his Sentosa Cove property. The first defendant was an architecture and engineering firm; the second defendant was the building contractor. The first defendant provided consulting engineering services, while the second defendant carried out the works. A quotation dated 21 June 2010 stated a contract price of $367,800 for the A&A Works. The scope was amended through a revised quotation attached to a letter dated 20 August 2010, but the contract price remained unchanged. The plaintiff made full payment of the contract price.
After completion, a dispute arose. The plaintiff alleged that the works were defective and incomplete. He commissioned two reports: a Building Appraisal report dated May 2011 identifying defects, and a Lee Consultants report dated January 2012 identifying discrepancies between the “as-built” work and the approved plans. These reports were collectively referred to in the judgment as the “Consultants’ Reports”.
On 8 February 2012, the plaintiff’s solicitors issued a letter of demand to the first defendant seeking compensation for defective works. On the same date, the plaintiff’s solicitors also wrote to the Professional Engineers Board (PEB) to request investigation of the first defendant and its principal engineer, Koh Kok Peng. The plaintiff also wrote to the Building and Construction Authority (BCA) about Koh. The dispute then moved to mediation.
On 12 March 2012, the parties entered into a settlement agreement. Under the settlement agreement, a professional engineer was to be appointed to determine the scope and specifications of rectification works based on the Consultants’ Reports, and to ensure that the rectification works complied with statutory regulations and were of a standard commensurate with the price paid for the original works. The engineer was also tasked with preparing and calling for tenders, evaluating tenders, and awarding the rectification contract. The defendants were to pay the engineer’s fees, the costs of rectification works, and certain accommodation and storage costs for the plaintiff during the rectification period, as well as $20,000 for moving and costs. In return, the plaintiff agreed to refrain from filing complaints with the PEB.
What Were the Key Legal Issues?
The High Court identified three broad issues. First, whether the appointment of the professional engineer (Chan Yaw Fai) and his award of the rectification contract to Crystallite should be set aside. This required the court to consider the legal character of the expert determination mechanism and the circumstances in which a court may intervene.
Second, the court had to determine which party was in breach of the settlement agreement and what damages were due. The plaintiff claimed losses arising from the defendants’ refusal to make further payments after Chan awarded the contract. The defendants, conversely, argued that the plaintiff’s conduct amounted to breach, including breach of the “no PEB complaint” obligation and an implied term not to interfere with or exert influence over the professional engineer.
Third, the court had to consider whether the plaintiff and Chan conspired to injure the defendants. The defendants’ alternative case alleged conspiracy to fix Chan’s fees at an unreasonable amount, to increase the scope of rectification works beyond what was prescribed by the Consultants’ Reports, and to award the contract to a higher bidder rather than the lowest bidder (Winning Flag) after the first tender.
How Did the Court Analyse the Issues?
The court’s analysis began with the settlement agreement’s structure. The settlement was not merely a payment arrangement; it created a process for rectification that depended on a professional engineer’s independent judgment. The engineer’s role was central: he was to translate the Consultants’ Reports into a rectification scope and specifications, then run a tender process and award the contract. This meant that the engineer’s determinations were contractually significant and were intended to be relied upon by both parties to resolve the underlying construction dispute.
In considering whether Chan’s appointment and award should be set aside, the court focused on the threshold for judicial intervention in expert determination. While the extract provided does not reproduce the full legal discussion, the court’s approach is consistent with established principles: an expert determination clause is generally binding unless there is a demonstrable basis to set it aside, such as material departure from the mandate, lack of independence or impartiality, fraud, or other serious procedural or substantive irregularities. Allegations of influence or non-independence must be supported by credible evidence rather than suspicion.
The defendants argued that Chan was not independent and was controlled by, or acting under the influence of, the plaintiff and/or his agents. They also alleged that Chan materially departed from his instructions by expanding the rectification scope beyond what the Consultants’ Reports required, and by awarding the contract to Crystallite instead of the lower bidder Winning Flag. The court would therefore have to examine (i) what Chan was actually instructed to do under the settlement agreement, (ii) what he did in practice, and (iii) whether any deviations were material and attributable to improper influence rather than professional judgment.
On the evidence, the factual narrative shows that Chan’s fees were a point of contention. Chan quoted a lump sum of $88,000 for his fees, payable progressively. The defendants later felt the fees were too high. Around the end of March 2012, the defendants’ solicitor sought the plaintiff’s consent for Koh to contact Chan to see if Chan could “give a discount” and to clarify Chan’s scope. The plaintiff had no objections. After a meeting on 28 March 2012 between Koh, Chia, and Chan, Chan effectively agreed to a discount of $8,000, and the defendants paid Chan $19,260 as the first instalment while Chan returned $8,000 in cash. This sequence suggested that the defendants were not denied an opportunity to negotiate fees, and it undermined an inference that Chan’s fees were fixed through secret collusion.
The tender process also featured prominently. Chan conducted site visits on 3 and 4 April 2012, produced tender documents, and invited contractors to tender. A first tender was opened on 31 May 2012, with four contractors submitting bids. Chan initially planned to interview only the two higher bidders, but after objections from the defendants, all four tenderers were invited for tender interviews. Three tenderers were interviewed on 19 June 2012, and a second site show-round was conducted on 21 June 2012. Chan then handed a two-page questionnaire to each contractor relating to items in the tender documents. A second tender was opened on 26 June 2012, with revised bids. Chan awarded the rectification contract to Crystallite for $498,000 on 6 July 2012. The defendants were dissatisfied and refused to make further payments; the rectification works never started.
Against this background, the court’s reasoning would necessarily have addressed whether Chan’s award to Crystallite was inconsistent with the settlement agreement’s mandate. The settlement agreement required rectification works to be based on the Consultants’ Reports and to comply with statutory regulations and be commensurate with the price paid for the original works. It did not, on the face of the extract, impose a strict “lowest bid wins” rule. Therefore, the defendants’ argument that the contract should have been awarded to Winning Flag would depend on whether Chan’s evaluation criteria and tender process were properly aligned with the mandate and whether the higher bid represented a departure from the required scope or quality.
Similarly, the defendants’ allegation that Chan expanded the scope beyond the Consultants’ Reports required careful comparison between the Consultants’ Reports and the tender documents and specifications. The court would have had to determine whether any expansion was a legitimate professional response to ensure compliance and rectification effectiveness, or whether it was a material departure that could be attributed to improper influence. The settlement agreement itself contemplated that the rectification scope and specifications were to be “based on” the Consultants’ Reports and set out “on the basis of the most efficient manner to rectify the defects” to ensure compliance and commensurate standards. That language leaves room for professional engineering judgment and optimisation, which makes it harder to establish “material departure” without clear proof.
Finally, the court addressed breach and damages. The plaintiff claimed substantial losses, including outstanding engineer’s fees (inclusive of GST), costs of rectification works (inclusive of GST), rental for two apartments for four months, storage costs for four months, and further rental and storage costs for the period until completion. The defendants counterclaimed, including repayment of the $20,000 paid for moving and costs and net amounts paid to Chan for the first instalment of his fees, as well as professional fees and damages relating to the plaintiff’s complaint to the PEB. The court’s determination of breach would therefore turn on whether the defendants’ refusal to pay was justified by a successful challenge to the expert determination, or whether the defendants remained bound by the settlement mechanism despite dissatisfaction with the outcome.
What Was the Outcome?
Based on the court’s approach to the expert determination mechanism and the evidential requirements for setting aside Chan’s appointment and award, the High Court ultimately resolved the dispute by addressing whether the defendants had established a legally sufficient basis to unwind the settlement’s expert process. The practical effect of the decision was to determine whether the defendants were liable to pay the plaintiff the sums claimed under the settlement agreement, and whether the defendants’ counterclaims could stand.
In construction and settlement disputes of this kind, the outcome is often decisive for how parties structure rectification processes and how they challenge expert determinations. Here, the court’s reasoning would have clarified the limits of court intervention where parties have agreed to rely on a professional engineer’s determinations to finalise scope, tendering, and award.
Why Does This Case Matter?
This case is significant for practitioners because it illustrates how Singapore courts treat settlement agreements that incorporate expert determination-like mechanisms. Where parties agree that a professional engineer will set scope and specifications, run tendering, and award a contract, the courts will generally require a high threshold before interfering. Dissatisfaction with the outcome—such as awarding to a higher bidder or disagreement over fees—does not automatically justify setting aside the expert’s decision.
For lawyers advising clients in construction disputes, the case highlights the importance of drafting and evidencing the expert’s mandate. The settlement agreement’s language (“based on” the Consultants’ Reports; “most efficient manner” to rectify defects; compliance with statutory regulations; standard commensurate with the original contract price) provided the engineer with discretion. Parties seeking to challenge the expert’s decision must therefore be prepared to show material departure from the mandate, lack of independence supported by evidence, or other serious irregularities such as fraud or procedural unfairness.
From a litigation strategy perspective, the case also underscores the evidential burden for conspiracy allegations. Claims that an expert and a party colluded to fix fees or manipulate tender outcomes require more than inference; they require proof of improper agreement and causative conduct. The court’s treatment of the fee discount episode and the tender process—particularly the defendants’ ability to object and participate—demonstrates how courts may view conduct inconsistent with a narrative of covert collusion.
