Summary
This High Court decision concerns the legal consequences of a settlement agreement in a building dispute, where the parties agreed to appoint a professional engineer to determine the scope and specifications of rectification works and to run a tender process for those works. The central controversy was whether the professional engineer’s appointment and subsequent award of the rectification contract should be set aside, and which party was in breach of the settlement agreement.
The court (Lionel Yee JC) addressed allegations that the professional engineer (Chan) was not independent, was influenced by the Plaintiff and/or the Plaintiff’s agents, and materially departed from his instructions in awarding the tender to a higher bidder. The Defendants also alleged conspiracy to fix fees and to manipulate the tender outcome. On the Plaintiff’s side, the Plaintiff claimed damages for the Defendants’ refusal to proceed with the rectification works and for costs incurred in reliance on the settlement process.
Ultimately, the case illustrates how expert determination clauses embedded in settlement agreements are treated by the courts, the evidential burden for allegations of lack of independence or improper influence, and the contractual approach to identifying breach and quantifying damages where a rectification process never starts.
What Were the Facts of This Case?
The Plaintiff, Poh Cheng Chew, engaged the Defendants—an architecture/engineering firm (the First Defendant) and a building contractor (the Second Defendant)—to carry out additions and alterations (“A&A Works”) to a property at Sentosa Cove. The First Defendant provided consulting engineering services, while the Second Defendant executed the works. A quotation dated 21 June 2010 set out the contract price for the A&A Works at $367,800. Although the scope of works was amended through a revised quotation attached to a letter dated 20 August 2010, the contract price remained unchanged, and the Plaintiff made full payment.
After completion, a dispute arose. The Plaintiff alleged that the A&A Works were defective and incomplete. He commissioned two reports: the Building Appraisal Report (May 2011) identifying defects, and the Lee Consultants Report (January 2012) identifying discrepancies between “as-built” work and approved plans. These reports became important because the settlement agreement later required rectification works to be based on them.
On 8 February 2012, the Plaintiff issued a letter of demand to the First Defendant seeking compensation for defective works. On the same date, the Plaintiff’s solicitors also complained to the Professional Engineers Board (“PEB”) and requested investigation and action against Koh, and it appears the Plaintiff also complained to the Building and Construction Authority (“BCA”). The dispute then proceeded to mediation, culminating in a settlement agreement dated 12 March 2012.
Under the Settlement Agreement, the parties agreed to appoint a professional engineer to set out the scope and specifications of rectification works, prepare and call for a tender, evaluate tenders, and award the contract. The scope and specifications were to be “based on” the Consultants’ Reports and to be set out “on the basis of the most efficient manner to rectify the defects so as to ensure that the works comply with the required statutory regulations and are of a standard commensurate with the price paid” for the original works. The Defendants were to pay the professional engineer’s fees, the costs of rectification works, and certain accommodation and storage costs for the Plaintiff during rectification, as well as $20,000 as compensation for moving and costs. In exchange, the Plaintiff was to refrain from filing complaints (presumably to the PEB) against Koh or the Defendants.
What Were the Key Legal Issues?
The High Court framed several key issues. First, it had to determine whether Chan’s appointment and the award of the rectification contract to Crystallite should be set aside. This required the court to consider the legal standards applicable to expert determination and whether the Defendants could establish grounds such as lack of independence, improper influence, or material departure from the expert’s mandate.
Second, the court had to determine which party was in breach of the Settlement Agreement and what damages were due. The Defendants argued that the Plaintiff breached fundamental terms by continuing complaints to the PEB and by interfering with or exerting influence over the professional engineer. The Plaintiff, conversely, treated the Defendants’ refusal to make further payments and proceed with rectification as breach.
Third, the Defendants advanced an alternative case of conspiracy: that the Plaintiff and Chan conspired to fix Chan’s fees at an unreasonable level, to increase the scope and specifications beyond those prescribed by the Consultants’ Reports, and to award the contract to a higher bidder rather than to Winning Flag after the first tender.
How Did the Court Analyse the Issues?
The court’s analysis began with the contractual architecture of the Settlement Agreement. The agreement did not merely contemplate expert input; it created a structured rectification mechanism: Chan was to define rectification scope/specifications based on the Consultants’ Reports, then run a tender process, evaluate bids, and award the contract. This meant the expert’s role was central to the parties’ bargain, and any challenge to the expert’s appointment or award had to be assessed against the settlement’s text and purpose.
On the Defendants’ challenge to Chan’s independence, the court considered the Defendants’ allegations that Chan was controlled by, or acted under the influence of, the Plaintiff and/or the Plaintiff’s agents. The factual narrative included a discussion about Chan’s fees. Chan quoted lump sum fees of $88,000, payable progressively. The Defendants felt the fees were too high and sought consent for Koh to contact Chan to request a discount and clarify Chan’s scope. The Plaintiff had no objections. After a meeting on 28 March 2012 between Koh, Chia, and Chan, Chan agreed to a discount of $8,000, and the Defendants received a cash return of $8,000 while paying the first instalment of $19,260.
The court treated this fee negotiation as a key evidential point. While the Defendants argued it showed improper influence, the court had to distinguish between legitimate interactions necessary to clarify scope and negotiate fees within the settlement framework, and impermissible interference with the expert’s independent judgment. The presence of Plaintiff’s solicitor consent to Koh contacting Chan for a discount and clarification suggested that some level of engagement was contemplated. The court’s reasoning therefore focused on whether the Defendants could show that such engagement crossed the line into improper control over Chan’s determinations.
Next, the court examined the tender process and whether Chan materially departed from his instructions. Chan conducted site visits on 3 and 4 April 2012 and produced tender documents for rectification works. The tender documents were forwarded for comments, and amendments were made pursuant to the Plaintiff’s comments, which the Defendants did not object to. Chan then invited tenders on 10 May 2012, conducted a first site show-round on 17 May 2012, and opened the first tender on 31 May 2012. Four contractors submitted bids, with Winning Flag being the lowest among the bidders at $188,800, and others submitting significantly higher amounts. Chan initially intended to call for tender interviews with only the two higher bidders, Effulgent and Crystallite, but after Defendants’ objections, all four tenderers were invited for interviews. Three tenderers were interviewed on 19 June 2012, and a second site show-round occurred on 21 June 2012. Chan then handed each contractor a two-page Tender Questionnaire relating to items in the tender documents.
After the second tender was opened on 26 June 2012, revised bids were submitted. Winning Flag’s bid increased dramatically to $498,000, while Effulgent remained at $542,318 and Crystallite reduced to $566,200. Chan awarded the rectification contract to Crystallite for $498,000 on 6 July 2012. The Defendants were dissatisfied and did not make further payments; importantly, the rectification works never started.
In assessing whether Chan departed from his mandate, the court had to interpret the Settlement Agreement’s requirement that rectification scope/specifications be “based on” the Consultants’ Reports and be set out in the most efficient manner to rectify defects while ensuring compliance with statutory regulations and a standard commensurate with the original contract price. The Defendants’ position was that Chan increased scope/specifications beyond what the Consultants’ Reports prescribed. The court’s approach would have required careful comparison between the Consultants’ Reports and the tender documents and award outcome, as well as an evaluation of whether any differences were within the expert’s discretion to design efficient rectification measures.
Finally, the court addressed the conspiracy allegations. The Defendants claimed that the Plaintiff and Chan conspired to fix Chan’s fees at an unreasonable amount, to expand scope/specifications, and to award the contract to a higher bidder instead of Winning Flag after the first tender. Such allegations require more than suspicion; they require cogent evidence of agreement or concerted action and of improper purpose. The court would therefore have scrutinised the chronology of events, the communications between parties, the tender mechanics, and the reasonableness of fee arrangements in light of the settlement’s terms and the discount actually granted.
What Was the Outcome?
The court’s decision resolved the Defendants’ attempt to set aside Chan’s appointment and the award to Crystallite, and it determined the breach/damages consequences of the parties’ failure to proceed with rectification. The practical effect was that the Settlement Agreement’s rectification mechanism did not translate into actual rectification works, and the dispute shifted to financial consequences.
While the provided extract does not include the final dispositive orders, the case is significant because it addresses whether a party can successfully undermine an expert determination embedded in a settlement by alleging lack of independence, improper influence, or conspiracy, and it clarifies how damages claims are approached when the rectification process is stalled.
Why Does This Case Matter?
This case matters for practitioners because it sits at the intersection of building disputes, settlement agreements, and expert determination. In many construction and renovation disputes, parties resolve claims by agreeing to an expert-led rectification or valuation mechanism. Poh Cheng Chew demonstrates that courts will treat such mechanisms seriously, and challenges must be grounded in legally relevant grounds rather than mere dissatisfaction with outcomes.
For lawyers advising on drafting and dispute strategy, the decision highlights the importance of defining the expert’s mandate and the boundaries of permissible interaction. The Settlement Agreement in this case required rectification scope/specifications to be based on specified reports and to be efficient and compliant. Where parties later allege interference, the court will likely examine whether the alleged conduct is consistent with legitimate process management (such as fee clarification and tender documentation comments) or whether it amounts to improper control over the expert’s independent judgment.
For litigators, the case also illustrates the evidential burden for conspiracy-type allegations. Claims that the expert and a party “fixed” fees or manipulated tender outcomes require substantial proof of concerted action and improper purpose. Without such proof, courts may be reluctant to set aside expert determinations, particularly where the process includes procedural safeguards (such as tender interviews, site show-rounds, and questionnaires) and where the expert’s actions can be rationalised as within the scope of the mandate.
