What Is This Legislation About?
The Architects (Professional Conduct and Ethics) Rules 2001 (“the Rules”) set professional and ethical expectations for people and entities authorised to practise architecture in Singapore. In practical terms, the Rules translate the broad idea of “professional conduct” into enforceable requirements that registered architects, and also licensed corporations and licensed partnerships, must follow when providing architectural services.
The Rules do not operate in isolation. They are made under the Architects Act 1991 and are designed to support the regulatory framework administered by the relevant professional regulator (the “Board” referred to in the Rules). The Board’s role includes issuing pronouncements on professional matters and ethics, and managing disputes that arise between practitioners or between a practitioner and a member of the public.
In addition to ethical duties and dispute-handling mechanisms, the Rules address commercial and procedural issues that commonly arise in practice—particularly how fees should be handled where architectural services are only partially performed or are terminated. This is important because fee disputes frequently overlap with allegations of misconduct, poor performance, or failure to deliver agreed scope.
What Are the Key Provisions?
1) The Code of Professional Conduct and Ethics (Rule 2)
Rule 2 is the core compliance provision. It requires every registered architect to observe and be guided by (a) Parts 1 and 2 of the Code of Professional Conduct and Ethics set out in the Schedule, and (b) the Board’s pronouncements on professional matters and professional conduct and ethics issued from time to time.
For licensed corporations and licensed partnerships, the Rules impose a similar obligation, but limited to Part 1 of the Code (rather than Parts 1 and 2). The distinction reflects that Part 2 may be directed more specifically at individual professional conduct, while Part 1 sets broader standards applicable to entities rendering architectural services.
Practical effect: a practitioner’s ethical obligations are not confined to the text of the Schedule. The Board’s ongoing pronouncements can update or clarify expectations, meaning compliance is a dynamic obligation. For practitioners, this creates a need for continuous monitoring of Board guidance and internal governance systems to ensure that conduct aligns with both the Code and any subsequent pronouncements.
2) Disputes between architects (Rule 3)
Rule 3 addresses disputes between two or more registered architects, licensed corporations, or licensed partnerships relating to professional conduct or ethics that are referred to the Board. The Board is required to take specific procedural steps.
First, the Board must require the concerned practitioner(s) to submit a written statement of the matters at issue. The Registrar must place the statement before the Board at its next meeting. Second, the Board must consider the parties’ statements and then either: (i) determine the dispute in the manner it thinks fit, or (ii) with the parties’ consent, refer the dispute for mediation by an agreed person (or, failing agreement, by the Board or a mediation centre).
If mediation fails, Rule 3 empowers the Board to recommend further mediation or, if the parties agree to be bound by an arbitrator’s decision, refer the dispute to arbitration with an arbitrator appointed by the Board. This creates a graduated dispute-resolution pathway: Board determination or mediation first, and then potentially arbitration if the parties consent to be bound.
3) Disputes between a practitioner and another person (Rule 4)
Rule 4 covers disputes between a registered architect, licensed corporation, or licensed partnership and another person. Here, the Board’s role is more facilitative than mandatory. The Board may refer the parties to mediation with the consent of the parties. If mediation does not resolve the dispute, the Board may recommend further mediation or, again with party agreement to be bound, refer the dispute to arbitration by an arbitrator appointed by the Board.
Practical effect: unlike Rule 3, Rule 4 does not expressly require the Board to determine the dispute itself after receiving statements. Instead, it focuses on mediation and arbitration pathways. For practitioners, this means that when disputes involve clients, contractors, or members of the public, the likely route is negotiated resolution (mediation) and, if necessary, binding adjudication (arbitration) subject to consent.
4) Board’s entitlement to recover expenses (Rule 5)
Rule 5 allows the Board to recover expenses incurred in three categories of activity: (a) determining disputes under Rule 3(1)(b)(i); (b) giving specific advice to a registered architect, licensed corporation, licensed partnership, or any member of the public upon request; and (c) referring disputes for mediation or to an arbitrator under Rules 3 or 4.
This provision is significant for budgeting and risk management. It signals that dispute resolution and advisory processes may carry recoverable costs, which can influence settlement dynamics and the cost-benefit analysis of pursuing or resisting Board processes.
5) Fees payable for partial services and termination (Rule 6)
Rule 6 is a detailed fee allocation rule. It applies where a registered architect, licensed corporation, or licensed partnership (the “claimant”) performs partial services for any reason (including abandonment, deferment, substitution, or omission of work) or where the claimant’s services are terminated for any reason.
In such cases, the claimant is entitled to fees for partial services rendered or services performed up to the termination date. The amount is either (i) as agreed between the parties, or (ii) in the absence of a specific agreement, according to a schedule of percentage-based fees tied to the stage of work completed.
The Rule sets out percentage benchmarks of the “total agreed fees” for successive stages, including:
- 20% for preliminary sketch designs sufficient to illustrate possibilities of a site or cost of a scheme (planning permission stage preparation);
- 25% for sketch designs, preliminary drawings and particulars sufficient to enable applications for permission under the Planning Act 1998 to be made;
- 45% for sketch designs, approximate cost estimates and sufficient drawings for applications for approval of building plans;
- 50% for sketch designs, cost estimates and drawings sufficient for building plan approval applications;
- 65% for obtaining planning permission and approval of building plans and preparing working drawings/specifications or other particulars necessary for bills of quantities or tenders.
Rule 6(1)(f) also explains that the 65% fee includes a proportion of the remaining 35% based on the value of completed building works relative to the total value of building works. This is an attempt to align architectural fee entitlement with the extent of project completion, even where the architectural services are terminated before full delivery.
Important limitations: Rule 6(3) provides that the rule does not apply where the architect (or entity) is also providing building services in the same project—whether on its own or with others. This carve-out matters because integrated design-and-build arrangements may be governed by different contractual and regulatory considerations.
How Is This Legislation Structured?
The Rules are structured as a short set of numbered rules supported by a Schedule. The Schedule contains the Code of Professional Conduct and Ethics, including at least two parts (Parts 1 and 2). The main body of the Rules then sets out:
(1) the citation and the obligation to follow the Code and Board pronouncements (Rule 2); (2) dispute procedures for disputes between practitioners (Rule 3); (3) mediation/arbitration pathways for disputes involving a practitioner and another person (Rule 4); (4) cost recovery for the Board (Rule 5); and (5) fee entitlement for partial services and termination (Rule 6).
Who Does This Legislation Apply To?
The Rules apply to three categories of regulated participants: registered architects, licensed corporations, and licensed partnerships that render architectural services in Singapore. The ethical obligations under Rule 2 apply to all three categories, with licensed corporations and partnerships required to observe Part 1 of the Code, while registered architects must observe both Parts 1 and 2.
In dispute contexts, the Rules also apply to the Board and the Registrar (procedural steps for written statements and Board consideration). For Rule 4, the “another person” can include clients or other stakeholders, meaning the dispute-resolution framework can be triggered even where the dispute is not strictly between two architects.
Why Is This Legislation Important?
For practitioners, the Rules matter because they define the ethical baseline against which conduct is assessed and because they provide a structured pathway for resolving disputes that relate to professional conduct and ethics. The requirement to follow both the Schedule’s Code and the Board’s pronouncements means that compliance is not static; it evolves as the Board issues further guidance.
From a dispute-resolution perspective, the Rules are particularly useful because they clarify procedural expectations: written statements for practitioner-to-practitioner disputes (Rule 3), consent-based mediation and arbitration for both categories of disputes (Rules 3 and 4), and the Board’s ability to recommend further mediation if initial mediation fails. This reduces uncertainty about process and can inform litigation strategy, settlement timing, and evidence planning.
Rule 6 is also practically significant. Fee disputes are common in architectural engagements, especially where scope changes, delays, or termination occur. By providing a stage-based percentage framework for “total agreed fees,” the Rules offer a default method for calculating entitlement in the absence of a specific agreement. For lawyers advising clients or architects, this can be a powerful reference point in negotiations and in assessing the likely outcome of fee-related claims.
