Question 1Case Study

Under the Buildings Ordinance, which body is the statutory authority responsible for approving building plans and issuing occupation permits in Hong Kong?

  1. The Hong Kong Institute of Architects
  2. The Buildings Department
  3. The Buildings Authority Correct answer.
  4. The Town Planning Board

Explanation

The Buildings Ordinance vests the statutory powers of plan approval, consent to commence, and occupation permits in the Building Authority, a statutory office normally held by the Director of Buildings. The Buildings Department is the administrative department that supports the Authority but is not itself the statutory decision-maker.

Question 2Case Study

A developer proposes a composite building on a site zoned "Commercial" in an Outline Zoning Plan. Which instrument primarily governs the permissible use and development intensity for that site?

  1. The Hong Kong Planning Standards and Guidelines
  2. The deed of mutual covenant
  3. The Outline Zoning Plan together with the Notes Correct answer.
  4. The Buildings Ordinance

Explanation

An Outline Zoning Plan is a statutory plan; its Notes set out the uses always permitted and those requiring planning permission, and the plan also indicates development restrictions. The Hong Kong Planning Standards and Guidelines are administrative guidance only and do not create the statutory use zone.

Question 3Case Study

What is the primary purpose of the site coverage and plot ratio controls in the Building (Planning) Regulations?

  1. To fix the minimum number of car parking spaces on a site
  2. To control the bulk and intensity of development on a site Correct answer.
  3. To determine the fire resistance period of structural elements
  4. To set the minimum width of escape staircases

Explanation

Site coverage limits the proportion of the site covered by buildings, while plot ratio limits total gross floor area relative to site area; together they control development bulk and intensity. They are planning tools and do not set parking, fire resistance, or staircase dimensions.

Question 4Case Study

In a building contract using the standard Hong Kong Government form, what does a performance bond primarily secure?

  1. The contractor's obligation to complete the works and remedy defects Correct answer.
  2. The consultant's professional indemnity obligations
  3. The employer's obligation to pay interim certificates on time
  4. The subcontractor's obligation to pay wages to workers

Explanation

A performance bond is provided by the contractor, usually through a surety, to secure due performance of the contract obligations including completion and rectification of defects. It protects the employer against contractor default rather than securing the employer's own payment duties.

Question 5Case Study

Which of the following best describes the role of a "nominated sub-contractor" in a traditional Hong Kong building contract?

  1. A sub-contractor nominated by the employer or architect but employed under the main contract Correct answer.
  2. A supplier of materials who has no contractual link to the works
  3. A sub-contractor selected by the main contractor without employer involvement
  4. A sub-contractor employed directly by the employer under a separate contract

Explanation

A nominated sub-contractor is chosen by the employer or architect for specialist work but is bound to the main contractor through a sub-contract, preserving a single point of responsibility. This differs from a direct contract with the employer or a domestic sub-contractor chosen freely by the main contractor.

Question 6Case Study

A candidate is preparing a submission for a statutory plan approval. Which set of drawings is normally required to demonstrate compliance with means of escape provisions?

  1. General building plans together with detailed floor plans showing escape routes and fire compartments Correct answer.
  2. A landscape masterplan
  3. A site location plan only
  4. General building plans only, at 1:500 scale

Explanation

Plan submissions must show both the overall building proposal and sufficient detail to demonstrate compliance with means of escape and fire compartmentation, typically through detailed floor plans. General plans alone at small scale do not evidence escape route widths and travel distances.

Question 7Case Study

What is the principal function of an occupation permit in Hong Kong?

  1. It transfers ownership of the building to the purchaser
  2. It confirms that the contractor has been paid in full
  3. It certifies that the building complies with the approved plans and is suitable for occupation Correct answer.
  4. It authorises the commencement of foundation works

Explanation

An occupation permit is issued by the Building Authority when the building substantially complies with the approved plans and relevant codes, permitting lawful occupation. It does not deal with title transfer, payment status, or authorising earlier construction stages.

Question 8Case Study

In Hong Kong, which organisation publishes the Code of Practice for Fire Safety in Buildings that designers use to demonstrate compliance?

  1. The Hong Kong Institute of Architects
  2. The Hong Kong Institution of Engineers
  3. The Fire Services Department
  4. The Buildings Department Correct answer.

Explanation

The Buildings Department publishes the Code of Practice for Fire Safety in Buildings, which sets out deemed-to-satisfy provisions for means of escape, fire resistance, and related matters. The Fire Services Department administers a separate ordinance on fire service installations and equipment.

Question 9Case Study

A client wants to appoint an architect for a project where the brief is incomplete and the scope may change significantly. Which fee basis best manages the client's risk of overpaying for work not required?

  1. A time-based fee with an agreed ceiling Correct answer.
  2. A lump sum percentage of final construction cost
  3. A fixed lump sum based on an early estimate
  4. A fee contingent on planning approval

Explanation

Where scope is uncertain, a time-based fee with a ceiling allows payment for work actually done while capping exposure. A fixed lump sum based on an early estimate risks disputes if scope grows, and a percentage of final cost can inflate fees without reflecting effort.

Question 10Case Study

During construction, the contractor discovers a discrepancy between the structural drawings and the specification regarding a beam size. Under a typical Hong Kong building contract, what should the contractor do first?

  1. Proceed with the smaller beam to save cost
  2. Suspend all works until the employer decides
  3. Amend the drawings and issue them to subcontractors
  4. Refer the discrepancy to the architect for a written instruction Correct answer.

Explanation

Contractors are expected to refer ambiguities and discrepancies to the architect, who issues instructions or clarifications that bind the parties. Unilateral decisions or amendments by the contractor bypass the contractual instruction process.

Question 11Case Study

An architect is asked to certify a contractor's interim payment application. Which principle best describes the certifier's duty?

  1. Certify the full amount applied for to avoid delay
  2. Certify a fair valuation of work executed and materials properly on site Correct answer.
  3. Certify the amount the employer wishes to pay
  4. Certify only after the contractor provides a performance bond

Explanation

Interim certification requires an independent valuation of work properly executed and materials on site, in accordance with the contract's measurement and payment provisions. Certification is not a discretionary favour to either party and must reflect the contract.

Question 12Case Study

Which of the following situations most clearly requires an application for planning permission under an Outline Zoning Plan?

  1. Changing to a use listed as requiring permission in the Notes Correct answer.
  2. Erecting a building on land within a zone where the use is always permitted
  3. Repainting the external facade in the same colour
  4. Carrying out minor internal renovation with no change of use

Explanation

Where the Notes to an Outline Zoning Plan list a use as requiring permission, an application to the Town Planning Board is necessary. Uses listed as always permitted, and works with no change of use, generally fall outside that requirement.

Question 13Case Study

A design team is considering a performance-based fire engineering approach for an atrium. What is the key requirement for such an approach to be accepted?

  1. It must eliminate all fire service installations
  2. It must demonstrate equivalent or superior safety to the deemed-to-satisfy provisions through accepted engineering analysis Correct answer.
  3. It must be cheaper than the prescriptive solution
  4. It must be approved by the contractor

Explanation

Performance-based design is accepted where engineering analysis demonstrates that the fire safety objectives are met at least as well as the prescriptive code. Cost is not the criterion, and fire service installations are typically still required.

Question 14Case Study

In administering a Hong Kong building contract, what is the effect of an extension of time granted by the architect for a relevant event?

  1. It transfers responsibility for delay to the employer
  2. It relieves the contractor of the obligation to complete the works
  3. It adjusts the completion date without necessarily giving rise to loss and expense Correct answer.
  4. It automatically entitles the contractor to additional payment for prolongation

Explanation

An extension of time adjusts the contractual completion date for a relevant event; it does not by itself establish a money entitlement, which depends on the contract's loss and expense provisions. The contractor remains obliged to complete by the revised date.

Question 15Case Study

Which document in a traditional building contract typically takes precedence when there is an inconsistency between the priced bill of quantities and the specification?

  1. The contractor's tender query responses
  2. The specification, because it describes quality
  3. The order of precedence stated in the contract conditions Correct answer.
  4. The priced bill of quantities, because it carries prices

Explanation

Most standard forms include an order of precedence clause that resolves inconsistencies between contract documents. Absent such a clause, disputes arise, so the contract conditions are the primary source for resolving priority.

Question 16Case Study

An architect is preparing a feasibility study for a site with a steep gradient. Which statutory or administrative control is most directly relevant to the siting of the building?

  1. The lease conditions alone
  2. The Building (Planning) Regulations and the site's geotechnical constraints Correct answer.
  3. The sales brochure
  4. The deed of mutual covenant

Explanation

Building (Planning) Regulations address site formation and related planning matters, while geotechnical constraints from the site's slope require separate assessment. Lease conditions may add restrictions but are not the primary building control for siting on a steep site.

Question 17Case Study

What is the principal purpose of a pre-tender estimate in a Hong Kong project?

  1. To provide the client with a budget check before tenders are received Correct answer.
  2. To replace the bill of quantities
  3. To fix the contractor's final account
  4. To serve as the basis for certifying interim payments

Explanation

A pre-tender estimate gives the client a cost benchmark against which tenders can be assessed and budgets confirmed. It is not a contract document and does not fix the final account or interim payments.

Question 18Case Study

An architect notices that the contractor has deviated from approved plans on a structural element. What is the architect's most appropriate first action?

  1. Ignore it because the contractor is responsible for construction
  2. Issue a written instruction requiring rectification or a variation submission Correct answer.
  3. Report the matter only at the final inspection
  4. Certify the work as completed

Explanation

The architect should promptly record the deviation and issue a written instruction or require a variation submission so the matter is resolved contractually and statutorily. Ignoring or delaying action risks non-compliance with approved plans.

Question 19Case Study

In a design-and-build procurement route, how does the contractor's design responsibility differ from a traditional route?

  1. The contractor has no design responsibility in either route
  2. The contractor assumes design responsibility for the works, often through a novated design team Correct answer.
  3. The employer's consultant certifies all design decisions
  4. The architect retains sole design responsibility

Explanation

In design-and-build, the contractor takes responsibility for design as well as construction, frequently by novating the employer's original design team. This shifts design risk compared with the traditional route where the employer's architect leads design.

Question 20Case Study

A client asks whether a proposed rooftop structure requires approval. Which factor is most decisive in determining whether the structure falls within the definition of "building works" under the Buildings Ordinance?

  1. Whether the structure is of a prescribed nature and size requiring approval Correct answer.
  2. The contractor's preference
  3. The colour of the structure
  4. The availability of a performance bond

Explanation

Whether works require approval depends on whether they fall within the statutory definition of building works and any exemptions for minor works. Colour, contractor preference, and bonds are irrelevant to that classification.

Question 21Case Study

An architect is advising a client on the risks of a fixed-price lump sum contract for a project with a long duration and volatile material costs. Which risk is most significant?

  1. The architect will lose the ability to certify payments
  2. The employer will be unable to obtain an occupation permit
  3. The contractor may underprice the risk and later seek claims Correct answer.
  4. The project will automatically require planning permission

Explanation

In a fixed-price contract with volatile costs, contractors may price in risk or later pursue claims if circumstances change, creating cost uncertainty. The other options confuse contractual pricing with unrelated statutory or administrative matters.

Question 22Case Study

A site is subject to both a lease restriction limiting the building to residential use and an Outline Zoning Plan permitting commercial use. What is the correct approach for the architect advising the client?

  1. Proceed with residential use only, because the lease restriction must also be satisfied Correct answer.
  2. Ignore both and rely on the Buildings Ordinance
  3. Proceed with commercial use because the zoning plan is more recent
  4. Apply to the Buildings Department to override the lease

Explanation

Planning permission and lease restrictions operate in parallel; a use must satisfy both. A permissive zoning does not override a lease restriction, and the Buildings Department has no power to vary lease conditions.

Question 23Case Study

In a fire engineering analysis of a large covered plaza, the designer proposes extended travel distance supported by a smoke control system. Which principle governs acceptance of this alternative?

  1. The alternative must be justified by analysis showing tenability and escape objectives are met Correct answer.
  2. The Fire Services Department decides all means of escape matters
  3. The contractor may choose the approach during construction
  4. Extended travel distance is automatically acceptable if smoke control is provided

Explanation

Alternative solutions must be supported by engineering analysis demonstrating that the fire safety objectives, including tenability and escape, are satisfied. Providing smoke control alone does not automatically justify extended travel distance.

Question 24Case Study

An architect is asked to advise on whether a proposed change of use in an existing building triggers upgrading of fire service installations. Which consideration is most relevant?

  1. The contractor's programme
  2. The age of the building alone
  3. Whether the change of use results in a higher fire risk category requiring upgraded provisions Correct answer.
  4. The colour scheme of the new fit-out

Explanation

A change of use can move the premises into a different fire risk category, triggering requirements to upgrade fire service installations and means of escape. Building age alone is not the trigger, and programme or finishes are irrelevant.

Question 25Case Study

A client wishes to appoint a contractor before the design is complete to shorten the programme. Which procurement arrangement best matches this objective, and what is its principal risk?

  1. Traditional lump sum tender; risk of design changes
  2. Design-and-build; risk of no design responsibility
  3. Two-stage or management contracting; risk of reduced price competition and cost certainty Correct answer.
  4. Direct labour; risk of statutory approval

Explanation

Two-stage or management contracting allows early contractor involvement before design completion, compressing the programme. The trade-off is reduced price competition and less cost certainty at the outset.

Question 26Case Study

Under the Buildings Ordinance, which party is the 'authorized person' responsible for supervising building works and coordinating the prescribed plans submitted to the Building Authority?

  1. The owner's appointed project manager
  2. A registered architect or engineer listed on the register of authorized persons Correct answer.
  3. The licensed contractor carrying out the works
  4. The registered structural engineer who designs the foundations

Explanation

The Buildings Ordinance regime separates roles: the authorized person (AP) is the registered professional who prepares and coordinates plans and supervises works, while the registered structural engineer deals with structural design and the registered contractor executes construction. The AP is appointed by the owner and carries statutory responsibility for the submission and supervision.

Question 27Case Study

A developer proposes to demolish an existing building and erect a new one on a site zoned 'Residential (Group A)'. Which approval sequence best reflects the usual Hong Kong process before construction can start?

  1. Planning permission or lease modification where needed, then building plan approval, then consent to commence works Correct answer.
  2. Consent to commence works, then planning permission, then building plan approval
  3. Occupation permit, then building plan approval, then consent to commence works
  4. Building plan approval first, then planning permission, then occupation permit

Explanation

Planning and lease controls are resolved before or alongside detailed design, then prescribed plans are submitted to the Building Authority for approval, and only after approval is consent to commence works sought. The occupation permit comes at completion, not before construction.

Question 28Case Study

What is the primary legal effect of a 'satisfactory' occupation permit being issued for a new building?

  1. It confirms that all contractor defects have been rectified
  2. It authorises occupation of the building for the use stated, subject to any conditions imposed Correct answer.
  3. It transfers ownership of the building to the purchaser
  4. It certifies that the building complies with all lease conditions

Explanation

An occupation permit is the Building Authority's authorisation to occupy the building for the approved use, and it may carry conditions. It is not a certificate of lease compliance, title, or defect-free construction, which are governed by other instruments and processes.

Question 29Case Study

An architect is preparing a submission for a new building and must decide whether the project needs the Building Authority's approval of plans. Which factor is decisive?

  1. Whether the client has obtained a mortgage for the project
  2. Whether the site is within a new town
  3. Whether the building exceeds ten storeys
  4. Whether the works constitute 'building works' or 'street works' as defined in the Buildings Ordinance Correct answer.

Explanation

The trigger for the statutory submission regime is whether the proposed activity falls within the Ordinance's definitions of building works or street works. Height, financing and location do not by themselves determine whether approval is required, although they may affect other controls.

Question 30Case Study

In a Hong Kong building contract, what is the usual role of the architect in relation to practical completion?

  1. The quantity surveyor certifies practical completion after measuring the works
  2. The contractor alone declares practical completion by notice to the client
  3. The architect issues a certificate of practical completion when the works are complete except for minor items Correct answer.
  4. The Building Authority issues practical completion with the occupation permit

Explanation

Under the standard forms, the architect administers the contract and certifies practical completion once the works are substantially complete, with minor outstanding items and defects to be dealt with during the maintenance period. The certificate triggers consequences such as release of retention and commencement of the defects liability period.

Question 31Case Study

Which body hears appeals against decisions of the Building Authority on matters such as refusal of plans?

  1. The District Court
  2. The Lands Tribunal
  3. The Buildings Appeal Tribunal Correct answer.
  4. The Town Planning Board

Explanation

The Buildings Ordinance establishes an appeal mechanism through the Buildings Appeal Tribunal, which hears appeals against specified decisions of the Building Authority. The Lands Tribunal, District Court and Town Planning Board deal with different subject matters.

Question 32Case Study

An architect is advising a client on the statutory definition of 'building works'. Which activity most clearly falls within it?

  1. Erecting a new structural frame for an extension Correct answer.
  2. Rearranging loose furniture in an office
  3. Replacing a broken window pane with an identical one
  4. Repainting the internal walls of an existing flat

Explanation

Building works generally cover construction, alteration, demolition and structural additions, so erecting a structural frame for an extension is clearly within the definition. Minor cosmetic or maintenance activities and furniture arrangement do not normally constitute building works requiring approval.

Question 33Case Study

What is the principal purpose of the 'prescribed plans' submitted to the Building Authority?

  1. To notify neighbours of the proposed construction
  2. To record the contractor's tender price for the works
  3. To transfer the site from the vendor to the purchaser
  4. To demonstrate compliance with the Buildings Ordinance and its regulations so that approval and consent can be granted Correct answer.

Explanation

Prescribed plans are the statutory drawings and particulars by which the Building Authority assesses compliance with the Ordinance and regulations before granting approval. They are not a pricing record, a conveyance, or a neighbour notification mechanism.

Question 34Case Study

A developer wants to build on a site where the lease permits only 'residential purposes' but the Outline Zoning Plan zones it 'Commercial'. Which statement best describes the position?

  1. The lease is automatically varied by the zoning designation
  2. Neither the lease nor the OZP applies until the building is completed
  3. The lease restriction remains binding and must be addressed through lease modification or a permissible interpretation Correct answer.
  4. Planning permission alone is sufficient because the OZP overrides the lease

Explanation

Planning control and lease control operate in parallel; a permissive zoning does not override a restrictive lease condition. The developer must either obtain a lease modification or establish that the proposed use falls within the lease terms, in addition to any planning permission required.

Question 35Case Study

An architect is preparing a fire safety strategy for a composite building containing a shopping mall podium and residential tower. Which document is the primary reference for means of escape, fire resisting construction and access for firefighting?

  1. The Code of Practice for Fire Safety in Buildings issued by the Buildings Department Correct answer.
  2. The Building (Construction) Regulations only
  3. The Hong Kong Planning Standards and Guidelines
  4. The Code of Practice for Minimum Fire Service Installations and Equipment

Explanation

The Code of Practice for Fire Safety in Buildings sets out the deemed-to-satisfy provisions for means of escape, fire resisting construction and firefighting access. The minimum fire service installations code addresses active systems, while the planning guidelines and construction regulations cover different matters.

Question 36Case Study

In a performance-based fire engineering approach for a large atrium, which element is essential for the design to be accepted?

  1. A statement that the design is equivalent to the prescriptive code without further analysis
  2. A fire engineering assessment demonstrating that the performance requirements are met, supported by accepted engineering methods and agreed by the Building Authority Correct answer.
  3. A reduction in the number of exits to save cost
  4. A guarantee from the contractor that the atrium will not catch fire

Explanation

Performance-based design requires a documented fire engineering assessment showing that the functional requirements are satisfied using recognised methodologies, and it must be accepted by the Building Authority. A bare equivalence claim or contractor guarantee is not an engineering demonstration.

Question 37Case Study

An architect is asked to advise whether a proposed change of use in an existing building will require upgrading of fire service installations. Which consideration is most relevant?

  1. The market value of the property after conversion
  2. Whether the new use increases occupant risk or changes the fire safety provisions required for that use Correct answer.
  3. The contractor's preferred programme for the works
  4. The colour scheme of the proposed interior

Explanation

A change of use can alter occupant characteristics, numbers and hazard, which may trigger requirements to upgrade fire service installations and means of escape. Aesthetic, programming and valuation matters do not determine the fire safety requirements.

Question 38Case Study

An architect is certifying an interim payment. Which principle best describes the architect's function?

  1. The architect certifies the amount considered due based on the contract's valuation provisions, acting fairly between the parties Correct answer.
  2. The architect certifies the amount the employer instructs
  3. The architect certifies whatever amount the contractor requests
  4. The architect certifies only after the quantity surveyor's figure is approved by the employer

Explanation

The architect values the work and certifies the sum considered due in accordance with the contract, exercising independent judgement rather than acting as either party's agent. The certificate must reflect the contractual valuation provisions, not the parties' preferences.

Question 39Case Study

A contractor discovers a discrepancy between the structural drawings and the specification regarding reinforcement. What should the architect do first?

  1. Ask the Building Authority to decide which document governs
  2. Ignore the discrepancy until the next progress meeting
  3. Instruct the contractor to proceed with the cheaper option
  4. Issue a clarification or instruction resolving the discrepancy in accordance with the contract's priority provisions Correct answer.

Explanation

The architect should resolve the inconsistency promptly by issuing a clarification or instruction, applying the contract's document priority rules and any relevant design information. Choosing an option on cost or deferring the matter risks non-compliant or disputed work.

Question 40Case Study

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

  1. Lump sum fixed-price tender on completed drawings
  2. Traditional sequential design-tender-build
  3. Two-stage or negotiated tender with early works packages Correct answer.
  4. Direct negotiation with no defined scope

Explanation

Appointing a contractor before design completion is typically achieved through two-stage tendering or early works packages, allowing early contractor involvement while the design develops. A lump sum tender on completed drawings or the traditional sequence requires the design to be finished first.

Question 41Case Study

An architect is advising on a fixed-price lump sum contract for a project with a long duration and significant ground risk. Which risk is most relevant to highlight?

  1. The contract price will automatically adjust with inflation
  2. The contractor may price in a contingency for unforeseen ground conditions, increasing the tender sum Correct answer.
  3. The contractor cannot claim for any variation
  4. The employer will bear all ground risk under a lump sum contract

Explanation

Under a lump sum, the contractor bears the priced risk, so uncertain ground conditions are likely to be reflected in a contingency within the tender price. The employer may still bear risk for variations and certain defined events, and inflation adjustment depends on the contract terms.

Question 42Case Study

An architect notices that the contractor has deviated from approved plans on a structural element. What is the architect's most appropriate immediate action?

  1. Instruct the contractor to stop the affected work and investigate, then require rectification or a revised submission as appropriate Correct answer.
  2. Report the matter only at final completion
  3. Ignore the deviation because the contractor is responsible for construction means
  4. Certify the work as compliant to avoid delay

Explanation

A deviation from approved plans on a structural element raises safety and statutory compliance concerns, so the architect should require the work to stop and be investigated, with rectification or a proper revised submission. Certifying non-compliant work or delaying action would be a breach of professional duty.

Question 43Case Study

A site has a steep gradient and the architect is preparing a feasibility study. Which control is most likely to affect the developable area?

  1. The colour of the proposed façade
  2. The contractor's insurance premium
  3. The lease's user clause only
  4. The Building (Planning) Regulations and site formation requirements relating to slopes and retaining structures Correct answer.

Explanation

Steep sites engage planning regulations, site formation and slope safety requirements, which can constrain the building footprint and require geotechnical input. User clauses, insurance and aesthetics do not directly govern the developable area in this way.

Question 44Case Study

An architect is asked whether a small rooftop structure requires Building Authority approval. Which factor is most decisive?

  1. Whether the structure is visible from the street
  2. Whether the contractor has built similar structures before
  3. Whether the client considers it temporary
  4. Whether the structure falls within the definition of building works and any applicable exemption Correct answer.

Explanation

The decisive question is whether the rooftop structure constitutes building works under the Ordinance and whether any exemption applies. The client's view of temporariness, visibility, or the contractor's experience does not determine the statutory requirement.

Question 45Case Study

A design team proposes extended travel distance in a covered plaza supported by a smoke control system and a fire engineering analysis. Which condition is most important for acceptance?

  1. The analysis must show that tenability criteria are met for the design fire scenarios and be accepted by the Building Authority Correct answer.
  2. The plaza must be closed to the public at night
  3. The contractor must agree to maintain the system for one year
  4. The system must be the cheapest available option

Explanation

Extended travel distance in a performance-based design depends on demonstrating that tenability is maintained under the design fire scenarios, using accepted methods, and obtaining the Building Authority's acceptance. Cost, night-time closure and a short maintenance commitment do not establish the required safety performance.

Question 46Case Study

An architect is advising on whether a proposed change of use from office to a place of public entertainment will affect the statutory approval process. Which statement is most accurate?

  1. The change may require both planning permission and building plan submission, together with compliance with the specific safety requirements for the new use Correct answer.
  2. The occupation permit automatically covers any new use
  3. Only the contractor's licence is required
  4. No approval is needed because the building already exists

Explanation

A change to a place of public entertainment can engage planning control, building plan approval and the specific safety and licensing requirements for that use. An existing building or occupation permit does not automatically authorise a materially different use.

Question 47Case Study

An architect is considering a performance-based alternative to prescriptive means of escape in a high-rise building. Which statement best reflects the correct professional approach?

  1. The alternative must be justified by a fire engineering analysis and accepted by the Building Authority before it is adopted Correct answer.
  2. The architect may adopt the alternative once the client approves it
  3. The alternative may be adopted without documentation if it is common practice
  4. The alternative is automatically valid if it saves construction cost

Explanation

Departing from prescriptive provisions requires an engineering justification demonstrating equivalent or superior safety, and acceptance by the Building Authority. Client approval, cost savings or common practice do not substitute for the required analysis and acceptance.

Question 48Case Study

A client asks whether a proposed subdivision of a flat into smaller units requires statutory approval. Which consideration is most relevant?

  1. The estate agent's opinion on market demand
  2. The number of prospective tenants
  3. Whether the units will be sold or rented
  4. Whether the works involve building works or a material change affecting compliance with the Ordinance and regulations Correct answer.

Explanation

Subdivision often involves building works and may affect compliance with requirements such as fire safety, drainage and structural adequacy, so the statutory question turns on whether building works are involved and whether compliance is affected. Tenure and market factors do not determine the approval requirement.

Question 49Case Study

An architect is reviewing a contractor's programme and notes that a delay arises from a variation ordered by the architect. What is the most appropriate contractual consequence?

  1. The contractor bears the delay risk because it agreed the programme
  2. The architect must personally compensate the contractor
  3. The delay may entitle the contractor to an extension of time and, if the contract so provides, loss and expense Correct answer.
  4. No adjustment is made because variations do not affect time

Explanation

A delay caused by an architect-ordered variation is typically a relevant event entitling the contractor to an extension of time, and the contract may also provide for loss and expense. The contractor does not bear the risk of the employer's instructed change, and the architect is not personally liable.

Question 50Case Study

Under the Buildings Ordinance, which person is the 'authorized person' responsible for supervising building works on a project?

  1. The registered architect or registered building surveyor appointed to coordinate and supervise the works Correct answer.
  2. The registered geotechnical engineer who certifies the site formation
  3. The registered structural engineer who designs the load-bearing elements
  4. The registered specialist contractor who installs the foundation

Explanation

The Buildings Ordinance creates a system of registered professionals. The authorized person is the architect, building surveyor or engineer appointed to prepare plans and supervise works, while the structural engineer and geotechnical engineer provide specialist design input. Supervision is the authorized person's coordinating responsibility.
