Question 1Paper 4 (content domain not enumerated in the official source)

Under the Buildings Energy Efficiency Ordinance, which party is primarily responsible for ensuring that a prescribed building complies with the Building Energy Code at the time of major retrofitting?

  1. The owner of the prescribed building Correct answer.
  2. The property management company alone
  3. The registered electrical contractor only
  4. The tenant occupying the whole floor

Explanation

The Buildings Energy Efficiency Ordinance places the duty to comply with the Building Energy Code on the owner of the prescribed building. The owner must ensure prescribed building services installations meet the code when a major retrofit is carried out. Other parties may assist but do not carry the statutory obligation.

Question 2Paper 4 (content domain not enumerated in the official source)

In Hong Kong, which legislation principally governs the control of asbestos work and the licensing of asbestos contractors and supervisors?

  1. Air Pollution Control Ordinance
  2. Occupational Safety and Health Ordinance
  3. Factories and Industrial Undertakings (Asbestos) Regulation Correct answer.
  4. Waste Disposal Ordinance

Explanation

The Factories and Industrial Undertakings (Asbestos) Regulation controls asbestos work, including registration of asbestos contractors and supervisors and notification requirements. The Air Pollution Control Ordinance addresses emissions, not asbestos work licensing. The other ordinances deal with general safety or waste, not asbestos work control.

Question 3Paper 4 (content domain not enumerated in the official source)

A registered contractor is preparing a tender and must price preliminaries. Which item is normally classified as a preliminary rather than as a measured works item?

  1. Concrete in foundation footings
  2. Site supervision staff costs Correct answer.
  3. Reinforcement bars in columns
  4. Excavation for basement

Explanation

Preliminaries cover site management, supervision, temporary works and similar general obligations rather than permanent measured work. Concrete, reinforcement and excavation are measured works priced against quantities. Supervision staff costs are therefore a preliminary item.

Question 4Paper 4 (content domain not enumerated in the official source)

Under a standard Hong Kong building contract, a retention fund is normally held to secure which of the following?

  1. The contractor's site insurance premiums
  2. Payment of the contractor's subcontractors only
  3. Remedying defects during the maintenance period Correct answer.
  4. Payment of architect's fees

Explanation

Retention money is deducted from interim payments and held so the employer has security to remedy defects arising during the maintenance or defects liability period. It is not earmarked for insurance premiums or professional fees. Subcontractor payment may be affected but is not the purpose of retention.

Question 5Paper 4 (content domain not enumerated in the official source)

Which body is the statutory authority responsible for administering the Buildings Ordinance in Hong Kong?

  1. The Architectural Services Department
  2. The Hong Kong Housing Authority
  3. The Buildings Department Correct answer.
  4. The Urban Renewal Authority

Explanation

The Buildings Department administers the Buildings Ordinance, processing building plans and issuing permits and occupation permits. The Housing Authority develops and manages public housing rather than administering the Ordinance. The other bodies deliver projects or urban renewal and are not the statutory building authority.

Question 6Paper 4 (content domain not enumerated in the official source)

Under the Personal Data (Privacy) Ordinance, a design practice collects client contact details for a project. What principle chiefly limits using that data later for unrelated marketing?

  1. The data accuracy principle
  2. The data use limitation principle Correct answer.
  3. The data openness principle
  4. The data security principle

Explanation

The data use limitation principle requires personal data to be used only for the purpose for which it was collected or a directly related purpose, unless the data subject consents. Accuracy, security and openness principles impose different obligations. Using contact data for unrelated marketing without consent would breach the use limitation principle.

Question 7Paper 4 (content domain not enumerated in the official source)

In a Hong Kong professional practice, which document typically records the agreed scope of services, fee basis and the allocation of responsibilities between architect and client?

  1. The building contract
  2. The occupation permit
  3. The interim payment certificate
  4. The memorandum of agreement or appointment contract Correct answer.

Explanation

The appointment contract or memorandum of agreement sets out the architect's scope, fee basis and responsibilities to the client. The building contract governs the relationship between employer and contractor. Occupation permits and payment certificates are statutory or administrative documents, not professional appointments.

Question 8Paper 4 (content domain not enumerated in the official source)

A contractor submits a claim for an extension of time due to exceptionally adverse weather. Under a typical Hong Kong building contract, what must the contractor generally demonstrate?

  1. That the delay event is a specified cause and actually affects completion Correct answer.
  2. That the contractor incurred additional cost only
  3. That the delay occurred on a public holiday
  4. That the architect verbally agreed to the delay

Explanation

An extension of time requires the contractor to show that the delay arises from a cause recognised by the contract and that it actually affects the completion date. Cost alone does not establish entitlement to time. Verbal agreement or the calendar status of a day is not the governing test.

Question 9Paper 4 (content domain not enumerated in the official source)

In Hong Kong, which of the following is a key purpose of the Mandatory Building Inspection Scheme?

  1. To require owners of older buildings to inspect and rectify building safety issues Correct answer.
  2. To license estate agents
  3. To set fire insurance premiums
  4. To certify the energy performance of new buildings

Explanation

The Mandatory Building Inspection Scheme requires owners of buildings reaching a specified age to appoint qualified inspectors and rectify identified safety defects. It is a building safety measure. Energy certification, estate agency licensing and insurance premiums fall under different regimes.

Question 10Paper 4 (content domain not enumerated in the official source)

An architect is asked to certify a variation valuation. Which approach best reflects sound contract administration?

  1. Apply the contractor's quoted lump sum without checking against the contract
  2. Defer valuation until final account without records
  3. Adopt the lowest rate found in the market regardless of the contract
  4. Value the work using rates or prices in the contract where applicable, and record the basis Correct answer.

Explanation

Variation valuation should follow the contract's valuation rules, using contract rates or prices where relevant and recording the basis for the decision. Accepting a quoted sum unexamined or deferring without records undermines accountability. Market rates unrelated to the contract are not the governing basis.

Question 11Paper 4 (content domain not enumerated in the official source)

Under Hong Kong's construction safety regime, which duty rests principally on the contractor regarding a temporary working platform?

  1. Ensuring the platform is designed, erected and maintained safely by competent persons Correct answer.
  2. Asking the client to design the platform
  3. Leaving platform safety to the manufacturer alone
  4. Relying on workers to inspect the platform each morning

Explanation

The contractor must ensure temporary works such as working platforms are properly designed, erected, inspected and maintained by competent persons. Worker self-inspection does not discharge the employer's duty. Clients and manufacturers do not bear the contractor's site safety responsibility.

Question 12Paper 4 (content domain not enumerated in the official source)

Which statement best describes the role of the Authorized Person under the Buildings Ordinance?

  1. A registered structural engineer only
  2. A contractor licensed to carry out general building works
  3. An officer of the Buildings Department
  4. A person registered to supervise building works and submit plans on behalf of owners Correct answer.

Explanation

An Authorized Person is registered under the Buildings Ordinance to prepare and submit plans and to supervise building works for owners. A contractor holds a different registration, and Authorized Persons are private practitioners rather than departmental officers. A registered structural engineer is a separate registration.

Question 13Paper 4 (content domain not enumerated in the official source)

In preparing a final account, an architect discovers an arithmetic error in an interim certificate already paid. What is the most appropriate professional response?

  1. Deduct the amount silently from the next payment
  2. Identify the error, assess its contractual effect, and correct it transparently in the final account Correct answer.
  3. Ignore it because the certificate was already paid
  4. Report the contractor to the Buildings Department

Explanation

Errors in certified sums should be identified and corrected transparently through the contractual valuation process, usually at final account. Ignoring the error or making silent deductions undermines fairness and the audit trail. The Buildings Department does not deal with payment errors.

Question 14Paper 4 (content domain not enumerated in the official source)

Which of the following best explains why a bill of quantities is prepared using a standard method of measurement?

  1. To fix the contractor's profit margin
  2. To guarantee the lowest possible tender price
  3. To give all tenderers a common and comparable basis for pricing Correct answer.
  4. To replace the need for drawings

Explanation

A standard method of measurement ensures items are described and measured consistently so tenderers price on a common basis, aiding comparison and later valuation. It does not guarantee low prices or fix profit margins. Drawings remain essential and are not replaced.

Question 15Paper 4 (content domain not enumerated in the official source)

A client wants to appoint a contractor before the design is complete to shorten the programme. Which procurement approach best matches this intention?

  1. Direct negotiation with no defined scope
  2. Traditional lump sum tender on completed drawings
  3. Selective tender after full documentation
  4. Management contracting or construction management Correct answer.

Explanation

Management contracting and construction management allow early contractor involvement while design continues, compressing the overall programme. Traditional lump sum and selective tendering require completed documentation. Negotiation without a defined scope does not reliably achieve the intended programme benefit.

Question 16Paper 4 (content domain not enumerated in the official source)

Which Hong Kong ordinance principally controls the discharge of pollutants into waters and the granting of discharge licences?

  1. Buildings Ordinance
  2. Gas Safety Ordinance
  3. Electricity Ordinance
  4. Water Pollution Control Ordinance Correct answer.

Explanation

The Water Pollution Control Ordinance controls pollution of Hong Kong waters and provides for discharge licences. The Buildings Ordinance governs building control, while the Electricity and Gas Safety Ordinances regulate electrical and gas installations. None of those three controls water discharge.

Question 17Paper 4 (content domain not enumerated in the official source)

An architect notices that a contractor's proposed substitution would reduce durability but lower cost. What is the most appropriate professional course?

  1. Reject it without giving reasons
  2. Approve it because it saves the client money
  3. Assess the substitution against the specified performance requirements and advise the client objectively Correct answer.
  4. Ask the contractor to decide and record the outcome

Explanation

The architect should evaluate any substitution against the specified performance and durability requirements and give objective advice to the client. Approving solely on cost or rejecting without reasons is unprofessional. Leaving the decision to the contractor abandons the architect's advisory role.

Question 18Paper 4 (content domain not enumerated in the official source)

In a Hong Kong building contract, what is the usual effect of practical completion certification?

  1. The employer takes possession and the defects liability period begins Correct answer.
  2. The contractor's liability for defects ends
  3. All retention is released immediately
  4. The final account becomes automatically agreed

Explanation

Certification of practical completion normally triggers the employer's right to take possession and marks the start of the defects liability or maintenance period. Retention is usually partly released, not fully. Liability for defects and agreement of the final account are not concluded at that point.

Question 19Paper 4 (content domain not enumerated in the official source)

A project involves demolition of a structure that may contain asbestos. Which action best reflects the regulatory position in Hong Kong?

  1. Proceed with demolition and stop only if dust appears
  2. Treat all debris as ordinary construction waste
  3. Arrange for a competent asbestos investigation before demolition and engage a registered contractor if asbestos is found Correct answer.
  4. Rely on the demolition contractor's verbal assurance

Explanation

Where asbestos may be present, a proper investigation should precede demolition, and any asbestos work must be carried out by a registered asbestos contractor under the relevant regulation. Proceeding until dust appears or treating debris as ordinary waste risks uncontrolled exposure. Verbal assurance is not an adequate substitute for investigation.

Question 20Paper 4 (content domain not enumerated in the official source)

Which principle best explains why the Buildings Department requires separate submissions by an Authorized Person, registered structural engineer and registered geotechnical engineer for certain projects?

  1. It removes the need for site supervision
  2. Each registered professional certifies the aspect within their own competence Correct answer.
  3. It transfers liability to the Buildings Department
  4. It spreads the fees among more consultants

Explanation

Separate submissions reflect the division of professional competence, with each registered professional certifying the aspect within their expertise. The arrangement does not exist to spread fees or remove supervision. Liability remains with the responsible parties, not the Buildings Department.

Question 21Paper 4 (content domain not enumerated in the official source)

Under a typical Hong Kong professional indemnity arrangement, which statement best describes the purpose of maintaining cover?

  1. To protect the practice against claims arising from professional negligence Correct answer.
  2. To cover the contractor's plant and equipment
  3. To replace the need for a site safety policy
  4. To insure the building against fire damage

Explanation

Professional indemnity insurance protects a practice against claims alleging professional negligence or breach of professional duty. It does not insure the building against fire, cover contractor plant, or substitute for safety management. Those risks fall under other insurances and duties.

Question 22Paper 4 (content domain not enumerated in the official source)

A design team is reviewing a contractor's programme and notices a deliberate overlap of activities that cannot physically occur together. What is the most appropriate professional response?

  1. Accept the programme because it shows early completion
  2. Adjust the contract completion date to match the programme
  3. Query the logic with the contractor and require a realistic programme Correct answer.
  4. Ignore the overlap as it is the contractor's risk

Explanation

An unrealistic programme should be queried and corrected so that it reflects achievable sequencing. Accepting impossible overlaps or adjusting the completion date without contractual basis is improper. Ignoring the issue leaves the project without a reliable programme for monitoring progress.

Question 23Paper 4 (content domain not enumerated in the official source)

Which of the following best describes the function of an occupation permit in Hong Kong?

  1. It approves the building plans for construction
  2. It authorises the commencement of foundation works
  3. It licenses the contractor to carry out works
  4. It certifies that a building is fit for occupation after completion of works Correct answer.

Explanation

An occupation permit is issued after completion to certify that the building is suitable for occupation. Commencement of works is authorised by consent to commence, and plan approval is a separate stage. Contractor licensing is not the function of an occupation permit.

Question 24Paper 4 (content domain not enumerated in the official source)

In tendering, what is the main purpose of a pre-qualification exercise?

  1. To guarantee that the lowest bidder wins
  2. To fix the contract sum before design
  3. To shortlist tenderers judged capable of carrying out the works Correct answer.
  4. To replace the need for a tender document

Explanation

Pre-qualification assesses experience, resources and capability so that only suitable firms are invited to tender. It does not fix the contract sum or remove the need for tender documents. It also does not guarantee that the lowest bidder will be selected.

Question 25Paper 4 (content domain not enumerated in the official source)

An architect is asked to approve a material sample that differs slightly from the specification but meets the stated performance. What is the appropriate approach?

  1. Assess whether the sample satisfies the specified performance and record the decision Correct answer.
  2. Refer the decision to the contractor's supplier
  3. Approve it without assessment to save time
  4. Reject any deviation automatically

Explanation

Approval should be based on whether the proposed material meets the specified performance requirements, with the decision recorded. Automatic rejection ignores equivalent alternatives, while approval without assessment or deferring to the supplier is improper. The architect must exercise independent professional judgement.

Question 26Paper 4 (content domain not enumerated in the official source)

Under the Buildings Ordinance (Cap 123), which body is empowered to grant approval of building plans and to issue occupation permits for private buildings in Hong Kong?

  1. The Buildings Department, acting through the Building Authority Correct answer.
  2. The District Lands Office
  3. The Lands Department
  4. The Hong Kong Institute of Architects

Explanation

The Building Authority, an office held by the Director of Buildings, administers the Buildings Ordinance and exercises statutory powers such as plan approval, consent to commence work and issuance of occupation permits. Professional institutes and other departments have advisory or land-administration roles but no such statutory authority.

Question 27Paper 4 (content domain not enumerated in the official source)

In Hong Kong, which statutory body hears appeals against certain decisions of the Building Authority, such as refusals of plan approval?

  1. The Lands Tribunal
  2. The Town Planning Board
  3. The Court of First Instance
  4. The Appeal Tribunal (Buildings) Correct answer.

Explanation

The Buildings Ordinance provides for an Appeal Tribunal (Buildings) to hear appeals against specified decisions of the Building Authority, giving an administrative appeal route before recourse to the courts. The Lands Tribunal deals with rating, tenancy and land compensation matters, and the Town Planning Board handles plan-making and planning applications.

Question 28Paper 4 (content domain not enumerated in the official source)

An Authorized Person signs a supervision plan for a building project. What is the principal purpose of that plan under the Buildings Ordinance regime?

  1. To replace the need for any registered structural engineer involvement
  2. To transfer the Building Authority's statutory duties to the contractor
  3. To set out how site supervision will be organised, resourced and recorded for the works Correct answer.
  4. To allocate construction cost between the client and the contractor

Explanation

The supervision plan is a statutory document describing the management structure, personnel, inspection frequency and reporting arrangements for supervising the works. It makes supervision arrangements explicit and auditable rather than transferring any statutory duty away from the appointed professionals.

Question 29Paper 4 (content domain not enumerated in the official source)

A developer proposes temporary works that support an excavation adjacent to a public road. Which statement best reflects the usual regulatory position in Hong Kong?

  1. Temporary works need no approval because they are removed before completion
  2. Temporary works are governed solely by the contractor's internal method statement
  3. Temporary works are approved only by the Highways Department in all cases
  4. Temporary works affecting the stability of the site or adjoining land may require plans and consent before construction Correct answer.

Explanation

Temporary works that affect site stability or the safety of adjoining land and structures can fall within the plan approval and consent regime, and may also need separate approval where they affect public roads. Internal method statements are good practice but do not substitute for statutory approval.

Question 30Paper 4 (content domain not enumerated in the official source)

Which Hong Kong ordinance principally governs the registration of architects and the disciplinary control of the profession?

  1. The Professional Engineers Registration Ordinance (Cap 409)
  2. The Housing Ordinance (Cap 283)
  3. The Buildings Ordinance (Cap 123)
  4. The Architects Registration Ordinance (Cap 408) Correct answer.

Explanation

The Architects Registration Ordinance establishes the Architects Registration Board, provides for registration of architects and sets out disciplinary procedures. The Buildings Ordinance deals with building control, while Cap 409 covers engineers and Cap 283 deals with public housing.

Question 31Paper 4 (content domain not enumerated in the official source)

A registered architect is the subject of a complaint about professional misconduct. Which body is empowered to inquire into the complaint and impose disciplinary sanctions under the Architects Registration Ordinance?

  1. The Independent Commission Against Corruption
  2. The Hong Kong Institute of Architects Council alone
  3. The Buildings Department
  4. The Architects Registration Board Correct answer.

Explanation

The Architects Registration Board administers registration and, through its disciplinary machinery, inquires into complaints of misconduct and may impose sanctions such as removal from the register. The HKIA is a professional institute whose own processes are separate from the statutory regime.

Question 32Paper 4 (content domain not enumerated in the official source)

In a Hong Kong construction contract, a dispute arises over the valuation of a variation. Which mechanism is most typical for resolving it before any litigation or arbitration?

  1. Immediate referral to the Court of First Instance
  2. Unilateral deduction by the client from the contract sum
  3. Reference to the contract's dispute resolution or adjudication procedure, such as mediation or expert determination Correct answer.
  4. Suspension of all work until the parties agree

Explanation

Standard forms generally provide a tiered route, requiring the parties to refer the dispute to the architect or an adjudicator, and often to mediation, before arbitration or litigation. This preserves the parties' relationship and avoids premature formal proceedings.

Question 33Paper 4 (content domain not enumerated in the official source)

Under a typical Hong Kong building contract, what is the usual consequence of the architect issuing an interim certificate?

  1. It states the amount payable at that stage, subject to later correction in subsequent certificates and the final account Correct answer.
  2. It releases the contractor from all defects liability obligations
  3. It finally and conclusively determines the value of all work done to date
  4. It transfers ownership of the works to the client

Explanation

Interim certificates are provisional statements of the sum due at a payment cycle and remain open to adjustment in later certificates and the final account. They do not conclusively fix value, transfer title or extinguish defects obligations.

Question 34Paper 4 (content domain not enumerated in the official source)

A Hong Kong employer wishes to withhold payment against an interim certificate because of alleged defective work. Which statement best reflects sound contract administration?

  1. The employer may ignore the certificate and wait for the final account
  2. The employer should follow the contract's notice and set-off provisions, stating the grounds and amount Correct answer.
  3. The employer may instruct the contractor's workforce directly to stop work
  4. The employer may withhold any amount it considers appropriate without notice

Explanation

Withholding payment is only permissible within the contractual framework, which typically requires a timely notice identifying the ground and the amount to be withheld. Acting outside that framework risks the withholding being invalid and exposes the employer to interest or default consequences.

Question 35Paper 4 (content domain not enumerated in the official source)

Which statement best describes the function of a performance bond in a Hong Kong construction contract?

  1. It provides the employer with security for the contractor's performance of its obligations Correct answer.
  2. It insures the works against fire damage
  3. It replaces the need for retention money in all cases
  4. It guarantees the quality of individual workmanship items

Explanation

A performance bond is a form of security, usually issued by a bank or insurer, that the employer can call on if the contractor fails to perform its obligations. It is distinct from insurance of the works and from retention, which is a separate deduction mechanism.

Question 36Paper 4 (content domain not enumerated in the official source)

An architect is preparing a tender package and must decide how risk for unforeseen ground conditions will be allocated. Which statement best reflects good practice?

  1. Risk should be allocated to the party best able to assess and manage it, and should be clearly stated in the tender documents Correct answer.
  2. Risk allocation should be left silent so that it can be resolved during construction
  3. Risk should always be retained by the architect personally
  4. All risk should always be transferred to the contractor regardless of information available

Explanation

Sound risk allocation assigns each risk to the party best placed to assess, price and manage it, and states that allocation clearly so tenderers can price consistently. Silent or unrealistic allocation tends to produce inflated prices or later disputes.

Question 37Paper 4 (content domain not enumerated in the official source)

In a Hong Kong design and build procurement, which statement best describes the employer's typical control over design quality?

  1. The employer controls quality through the employer's requirements and review of design submissions against them Correct answer.
  2. The employer has no means of controlling design quality once the contract is signed
  3. The employer must approve every drawing produced by the contractor's designers
  4. Design quality is controlled solely by the Building Authority

Explanation

In design and build the employer's influence is exercised through a well-drafted set of employer's requirements and contractual review points at which design submissions must be shown to comply. Day-to-day design decisions remain with the contractor's team.

Question 38Paper 4 (content domain not enumerated in the official source)

A client asks an architect to recommend a procurement route for a project where cost certainty at an early stage is the top priority and the design is already well developed. Which route is most consistent with that priority?

  1. Construction management with multiple trade contracts
  2. Traditional lump sum tendering on completed documentation Correct answer.
  3. Negotiated design and build before design is complete
  4. Management contracting with an early start on site

Explanation

When the design is sufficiently complete, competitive lump sum tendering against full documentation gives the greatest early cost certainty because tenderers price a defined scope. Routes involving early contractor involvement or incomplete design trade some cost certainty for speed or buildability input.

Question 39Paper 4 (content domain not enumerated in the official source)

Which statement best describes the role of a clerk of works on a Hong Kong building project?

  1. To determine contractual claims and issue final certificates
  2. To design structural elements and certify their adequacy
  3. To carry out day-to-day site inspection and report on workmanship and compliance with the drawings and specification Correct answer.
  4. To act as the contractor's site safety officer

Explanation

The clerk of works provides continuous site surveillance on behalf of the client or architect, recording workmanship, progress and compliance and reporting back. Design responsibility, certification of claims and safety management rest with other roles.

Question 40Paper 4 (content domain not enumerated in the official source)

An architect discovers that a contractor has departed from a specified fire-resisting construction detail. What is the most appropriate immediate professional response?

  1. Record the departure, require rectification or a properly justified alternative, and notify the client Correct answer.
  2. Accept the departure because the contractor is responsible for means of construction
  3. Conceal the issue until the final inspection
  4. Deduct a sum from the next certificate without any notice

Explanation

Fire-resisting construction is a life-safety matter and any departure must be recorded and resolved, either by rectification or by a properly justified and approved alternative. The client should be informed, and any financial adjustment must follow the contract's notice and valuation procedures.

Question 41Paper 4 (content domain not enumerated in the official source)

Which statement best describes the purpose of a site formation plan submitted in connection with building works in Hong Kong?

  1. To record the contractor's plant and labour returns
  2. To confirm the client's funding arrangements
  3. To show how the site will be formed, including slopes, retaining structures and drainage, so that stability can be assessed Correct answer.
  4. To set out the marketing strategy for the completed development

Explanation

Site formation plans describe the earthworks, slopes, retaining structures and drainage necessary to create a stable platform for the development, allowing the authorities to assess geotechnical and drainage implications. They are technical submissions, not commercial or financial documents.

Question 42Paper 4 (content domain not enumerated in the official source)

A project involves a sloping site where a new building will be founded close to an existing retaining wall. Which professional input is most directly required to assess the effect on the wall?

  1. A registered structural engineer with geotechnical expertise preparing an assessment of stability and ground movement Correct answer.
  2. A quantity surveyor preparing a cost plan
  3. An interior designer preparing a layout
  4. A landscape architect preparing a planting schedule

Explanation

The interaction between new foundations, excavation and an existing retaining wall is a geotechnical and structural stability issue requiring assessment by a registered structural engineer with the relevant expertise. Cost, landscape and interior inputs do not address ground stability.

Question 43Paper 4 (content domain not enumerated in the official source)

Under Hong Kong's energy efficiency regime for buildings, which statement best describes the purpose of the Building Energy Code?

  1. It governs the ownership of common parts in a development
  2. It prescribes the colour and texture of external finishes
  3. It sets minimum standards for the energy performance of building services installations and the building envelope Correct answer.
  4. It controls the hours during which construction may take place

Explanation

The Building Energy Code sets out minimum energy performance requirements for specified building services installations and envelope design, supporting the statutory energy efficiency framework. It does not deal with aesthetics, ownership of common parts or construction noise hours.

Question 44Paper 4 (content domain not enumerated in the official source)

In Hong Kong, which ordinance principally regulates the design, installation and maintenance of lifts and escalators in buildings?

  1. The Waterworks Ordinance (Cap 102)
  2. The Lifts and Escalators Ordinance (Cap 618) Correct answer.
  3. The Electricity Ordinance (Cap 406)
  4. The Gas Safety Ordinance (Cap 51)

Explanation

The Lifts and Escalators Ordinance provides for the registration of lift and escalator engineers and contractors and for the safety, inspection and maintenance of the equipment. The other ordinances govern electricity supply, gas installations and water supply respectively.

Question 45Paper 4 (content domain not enumerated in the official source)

A design team proposes to use a new cladding system whose fire performance has not been assessed under any recognised test standard. What is the most appropriate professional action?

  1. Require recognised fire test evidence or an assessment acceptable to the Building Authority before specifying it Correct answer.
  2. Specify it only on the upper floors to limit risk
  3. Rely on the contractor to decide whether it is acceptable
  4. Proceed because the supplier offers a warranty

Explanation

Materials affecting fire safety must be supported by recognised test evidence or an assessment acceptable to the Building Authority before they are specified. A supplier warranty is a commercial document and does not demonstrate fire performance, and the decision cannot be delegated to the contractor.

Question 46Paper 4 (content domain not enumerated in the official source)

An architect is appointed as contract administrator on a project where the client also employs a project manager with overlapping duties. Which action best reduces the risk of inconsistent instructions?

  1. Avoid communicating with the project manager
  2. Agree a clear division of responsibilities and a single channel for instructions in the appointment documents Correct answer.
  3. Defer all decisions to the contractor
  4. Issue instructions independently and resolve conflicts later

Explanation

Overlapping appointments create a real risk of conflicting instructions, so the respective roles, decision rights and communication channels should be defined in the appointment documents before work starts. Independent action and avoidance both increase the risk of confusion and claims.

Question 47Paper 4 (content domain not enumerated in the official source)

Which statement best describes the architect's duty when certifying a contractor's claim for additional payment?

  1. To act fairly and independently in valuing the claim in accordance with the contract Correct answer.
  2. To act as an advocate for the client's financial interests
  3. To refuse all claims to protect the client
  4. To accept the contractor's valuation without checking

Explanation

When certifying or valuing claims, the architect exercises a quasi-judicial function and must act fairly and independently, applying the contract's valuation rules rather than favouring either party. Advocacy, automatic acceptance and blanket refusal all breach that duty.

Question 48Paper 4 (content domain not enumerated in the official source)

A client wants to appoint a contractor before design is complete to shorten the programme. Which contractual arrangement best supports this while preserving cost transparency?

  1. A two-stage tender with a negotiated second stage and an open-book cost mechanism Correct answer.
  2. Award to the lowest bidder without any pre-qualification
  3. A fixed lump sum tender on incomplete drawings
  4. Appointment of a contractor with no defined scope or payment mechanism

Explanation

A two-stage approach allows early contractor involvement and programme saving while an open-book mechanism keeps costs transparent and auditable. Tendering a lump sum on incomplete drawings produces priced risk and disputes, and appointing without scope or payment terms is unworkable.

Question 49Paper 4 (content domain not enumerated in the official source)

In Hong Kong, which body is responsible for approving applications for temporary occupation of a building before an occupation permit is granted?

  1. The Hong Kong Institute of Architects
  2. The Building Authority, which may grant a temporary occupation permit subject to conditions Correct answer.
  3. The Consumer Council
  4. The Rating and Valuation Department

Explanation

The Building Authority may grant a temporary occupation permit allowing limited occupation before full completion, subject to conditions such as completion of essential safety works. The other bodies have no role in granting occupation approvals.

Question 50Paper 4 (content domain not enumerated in the official source)

An architect is reviewing a contractor's proposed alternative to a specified product. Which approach best reflects sound professional judgement?

  1. Approve it because it is cheaper
  2. Ask the supplier to confirm that it is equivalent
  3. Assess the alternative against the specified performance requirements and document the decision Correct answer.
