ALL
QUESTIONS ARE COMPILED TOGETHER.
1. A Quantity
Surveyor is preparing the preliminary cost estimate for a proposed district
hospital. The architectural drawings are still at an early stage and the gross
floor area is the most reliable information available. Which approach would
provide the most appropriate initial basis for estimating the building cost?
A. Apply a
suitable cost per square metre to the estimated gross floor area
B. Price every construction item from assumed quantities and provisional rates
C. Use the contractor’s previous final account as the complete project estimate
D. Estimate only the material costs before determining the overall project cost
Answer: A
Rationale: At the early design stage, detailed
quantities are normally unavailable, so a floor-area-based elemental or
functional cost approach provides a reasonable preliminary estimate using an
appropriate cost per square metre derived from comparable projects and adjusted
for relevant differences. Pricing every item from assumed quantities introduces
unnecessary uncertainty, while a previous final account cannot automatically
represent the current project. Estimating only materials also ignores labour,
plant, preliminaries, overheads and other project costs.
2. During
preparation of a BOQ for a public office building, the Quantity Surveyor
discovers that the architectural drawing shows a reinforced concrete staircase,
while the structural drawing provides different dimensions for the same
staircase. What should the Quantity Surveyor do before finalising the measured
quantities?
A. Use the
architectural dimensions because they define the building layout
B. Use the structural dimensions because concrete work is structural
C. Seek clarification and resolve the discrepancy using the contract
information
D. Measure both alternatives and include the larger quantity in the BOQ
Answer: C
Rationale: A discrepancy between coordinated
drawings should be resolved before the BOQ is finalised because using one
drawing arbitrarily can result in incorrect quantities, pricing and subsequent
disputes. The Quantity Surveyor should identify the discrepancy and obtain the
appropriate clarification through the project’s established communication and
documentation procedures. Neither architectural nor structural information
should automatically override the other merely because of the discipline
involved, and including both alternatives without clarification would distort
the tender information.
3. A
contractor submits a tender in which the rate for excavation is substantially
lower than the rates submitted by other tenderers, while the quantities in the
BOQ appear correct. Which issue should the Quantity Surveyor examine most
carefully before recommending acceptance?
A. Whether the
contractor used the same excavation equipment as competitors
B. Whether the rate reasonably covers all resources and obligations included in
the item
C. Whether the contractor has priced all other items above the market average
D. Whether the excavation quantity should be increased to compensate for the
low rate
Answer: B
Rationale: A very low unit rate should be examined
to establish whether the contractor has properly allowed for labour, plant,
materials where applicable, overheads, profit, risks and other obligations
covered by the measured item. A low rate is not automatically unacceptable, but
it may indicate an omission, misunderstanding, arithmetic issue or an
intentionally unbalanced tender. Equipment choice alone does not establish
whether the rate is adequate, and altering the BOQ quantity to compensate for a
contractor's pricing decision would be inappropriate.
4. A
government office building has reached the stage where completed work needs to
be valued for an interim payment. The contractor claims payment for materials
delivered to site, but some of the materials have not yet been incorporated
into the permanent works. What is the most important consideration before
including such materials in the valuation?
A. Whether the
materials have been delivered by the contractor's preferred supplier
B. Whether the materials have a higher value than the completed work
C. Whether the contractor has already paid the supplier in full
D. Whether the contract permits such materials to be valued and the required
conditions are satisfied
Answer: D
Rationale: Materials on site should not
automatically be included in an interim valuation merely because they have been
delivered or paid for by the contractor. The Quantity Surveyor must examine the
contract provisions and confirm that the materials satisfy the conditions for
payment, such as proper identification, suitability, protection, ownership or
vesting requirements and other stipulated conditions. The supplier selected and
the contractor's payment arrangements do not by themselves establish
entitlement to payment.
5. A proposed
rehabilitation project involves an existing public building whose original
drawings are unavailable. Before preparing a reliable cost estimate, the
Quantity Surveyor needs to establish the actual condition and extent of the
required works. Which activity is most appropriate?
A. Conduct a
physical condition survey and obtain measurements of the existing works
B. Apply the original construction cost using an appropriate inflation factor
only
C. Use the estimated floor area and assume that all existing components require
replacement
D. Request the contractor to determine the defects and use its quotation as the
estimate
Answer: A
Rationale: Rehabilitation estimating depends heavily
on the actual condition, dimensions and extent of deterioration of the existing
facility. A physical condition survey combined with measurement allows the
Quantity Surveyor to identify the work required and develop quantities and
rates based on actual site conditions. Inflation-adjusting an old cost does not
establish the present scope, assuming total replacement exaggerates the work,
and relying solely on a contractor's quotation would compromise the independent
preparation of the estimate.
6. A project
has an approved construction budget of TZS 2.0 billion. During design
development, the latest cost estimate reaches TZS 2.25 billion. Which response
is most appropriate for effective cost control?
A. Wait until
construction begins before discussing the increase
B. Remove all provisional items regardless of their necessity
C. Identify the causes of the variance and review the design and cost
implications
D. Reduce all measured quantities proportionately until the estimate equals the
budget
Answer: C
Rationale: Effective cost control requires
identifying why the estimate has exceeded the approved budget and then
assessing appropriate corrective measures. The Quantity Surveyor should analyse
cost movements, design development, scope changes, quantities, rates and other
relevant factors before recommending adjustments. Arbitrarily removing
provisional items or reducing quantities may compromise the project's
functional requirements, while waiting until construction begins removes an
important opportunity to control costs during the design stage.
7. In
preparing a rate for one cubic metre of reinforced concrete, the Quantity
Surveyor has determined the material quantities and their current prices. Which
additional consideration is essential for developing a realistic composite
rate?
A. The colour of
the contractor's company logo
B. Labour, plant, wastage, overheads and other applicable cost components
C. The number of government employees assigned to the project
D. The original tender price of an unrelated building project
Answer: B
Rationale: A realistic construction rate must
reflect the resources and costs necessary to execute the work. Depending on the
method of measurement and pricing structure, this may include materials,
labour, plant, wastage, transport and handling allowances, overheads, profit
and other relevant cost components. Material prices alone cannot represent the
complete cost of producing the measured unit of work, while unrelated project
prices and administrative details do not provide a reliable basis for the rate.
8. A
contractor requests payment for work that is physically complete, but the
Quantity Surveyor discovers that part of the claimed work does not comply with
the specified quality requirements. What is the most appropriate approach?
A. Certify the
entire amount because the work has physically been completed
B. Reject the entire project payment until the final completion certificate
C. Certify the claimed amount and allow the contractor to correct the work
later
D. Assess the compliant work and deal with the defective portion in accordance
with the contract
Answer: D
Rationale: Physical completion alone does not
necessarily establish entitlement to full payment where work fails to meet the
contractual requirements. The Quantity Surveyor should assess the value of
compliant work and treat defective or non-compliant work according to the
contract, including any applicable withholding, correction or other contractual
mechanism. Certifying defective work without qualification could expose the
project to financial and contractual risk, while withholding all payment until
final completion would also be inappropriate if substantial compliant work is
properly valued.
9. A public
building project experiences a substantial increase in the quantity of
foundation excavation because actual ground conditions differ from those
reasonably indicated by the available project information. What should the
Quantity Surveyor establish first when assessing the cost implication?
A. Whether the
contractor has changed its management staff
B. Whether the additional work is contractually measurable and properly
supported
C. Whether the contractor's profit percentage is higher than expected
D. Whether the project architect agrees with the contractor's original tender
price
Answer: B
Rationale: Before valuing additional excavation, the
Quantity Surveyor should establish the contractual basis for the work and
verify the actual quantities and supporting site information. The key issues
include whether the additional work falls within the contract scope, how it
should be measured, whether it is a variation or another contractual
entitlement, and what rates or valuation principles apply. Management staffing,
profit percentage and the original tender price do not determine whether the
additional excavation is properly payable.
10. A Quantity
Surveyor is comparing two proposed construction methods for a district
administrative building. Method A has a lower initial construction cost but
significantly higher expected maintenance costs over its useful life. Method B
costs more initially but has substantially lower maintenance requirements.
Which analysis would provide the better basis for a long-term value decision?
A. Compare only
the initial tender prices
B. Select the method with the lowest material cost
C. Consider the whole-life cost of each alternative
D. Select the method requiring the shortest construction period
Answer: C
Rationale: Whole-life costing considers costs
incurred throughout the relevant life of an asset rather than focusing
exclusively on the initial construction price. It may include construction,
operation, maintenance, replacement and other significant future costs. This
approach allows the client to assess long-term value and not merely the
cheapest initial option. Construction duration and material cost may be
relevant considerations, but neither alone provides an adequate assessment of
long-term economic performance.
11. While
preparing a BOQ, the Quantity Surveyor measures concrete work separately from
reinforcement and formwork in accordance with the applicable method of
measurement. What is the principal reason for separately measuring these
components?
A. They require
different quantities, resources and pricing considerations
B. They are always executed by three different contractors
C. They must always appear in three separate construction contracts
D. They have identical unit rates but different descriptions
Answer: A
Rationale: Concrete, reinforcement and formwork
represent distinct work components with different measurement characteristics,
resources, labour requirements, material inputs and pricing considerations.
Separating them enables accurate measurement, transparent tender pricing and
appropriate valuation of completed work. They do not necessarily have to be
executed by different contractors or placed under separate contracts, and their
rates are not expected to be identical.
12. A project
manager asks the Quantity Surveyor to reduce the estimated project cost without
reducing the required functional output of the building. Which measure best
represents a professional cost-management response?
A. Delete
necessary work items and allow the contractor to decide later
B. Substitute all specified materials with cheaper materials without approval
C. Reduce the contractor's profit allowance without changing the design
D. Investigate alternative designs or construction methods that provide
equivalent performance
Answer: D
Rationale: Cost management seeks to achieve the
required function and performance at an appropriate cost rather than simply
removing necessary work or arbitrarily reducing individual allowances.
Reviewing alternative designs, materials, construction methods or specifications
that can provide equivalent required performance may generate legitimate
savings. Unapproved material substitutions and arbitrary deletion of work can
compromise quality and functionality, while reducing a contractor's profit
allowance is not a proper design-based cost-management strategy.
13. A Quantity
Surveyor is preparing a project budget for a new secondary school. The client
has approved the accommodation schedule, but several design details are not yet
finalised. Which budget characteristic is most important at this stage?
A. It should
remain completely unchanged throughout design development
B. It should reflect the current scope and be updated as reliable information
develops
C. It should contain only the contractor's anticipated profit and overheads
D. It should be based exclusively on the cheapest available construction rates
Answer: B
Rationale: A project budget is a management tool
that should reflect the currently defined scope and the level of information
available at each stage of design development. As reliable design information
becomes available, quantities, specifications, rates and other assumptions may
change, requiring the budget to be reviewed and updated. A budget that cannot
respond to legitimate scope development is ineffective, while basing it only on
the cheapest rates or contractor profit would omit major components of project
cost.
14. During
tender analysis for a public construction project, one tender is substantially
below the client's estimate while another is significantly above it. Before
recommending a tender, which comparison is most useful?
A. Compare only
the names and ages of the tendering companies
B. Select the lowest tender automatically because it gives the greatest
apparent saving
C. Analyse the tender prices, rates, qualifications, arithmetic and compliance
with requirements
D. Average all tender prices and award the contract to the tender closest to
the average
Answer: C
Rationale: Tender evaluation requires more than
ranking contractors by total price. The Quantity Surveyor should analyse the
submitted prices and rates, check arithmetic, identify qualifications or
exclusions, examine unusual pricing patterns and consider compliance with the
tender requirements within the applicable procurement framework. The lowest
tender is not automatically the most appropriate if it contains significant
qualifications, errors or other concerns, and averaging tenders is not a
substitute for proper evaluation.
15. A Quantity
Surveyor is preparing the cost estimate for a proposed LGA office building. The
project will be constructed in an area where access to the site is difficult
and construction materials must be transported over a considerable distance.
Which factor should be given particular consideration when developing the
estimate?
A. The
contractor's preferred office location and administrative structure
B. The number of employees expected to occupy the completed building
C. The client's previous expenditure on unrelated public projects
D. Transport, delivery and site-access costs associated with the project's
location
Answer: D
Rationale: Site location and accessibility can have
a significant effect on construction costs, particularly where materials,
equipment and labour must travel considerable distances or where difficult
access increases transportation, handling and delivery requirements. A reliable
estimate should therefore reflect relevant location-specific costs rather than
relying solely on standard rates from more accessible projects. The
contractor's office arrangement, building occupancy and unrelated government
expenditure do not directly establish the project's construction cost.
16. A
contractor's interim valuation includes a claim for a large quantity of
earthworks. The Quantity Surveyor's site records show that the measured
quantity differs significantly from the contractor's submitted quantity. What
should form the primary basis for the valuation?
A. The
contractor's submitted quantity because it has signed the payment application
B. The quantity verified in accordance with the contract's measurement
procedures and records
C. The quantity from the original estimate regardless of actual site progress
D. The average quantity claimed by the contractor and the supervising
consultant
Answer: B
Rationale: Interim valuations should be based on
quantities properly measured or verified in accordance with the contract and
supported by reliable site records. A contractor's payment application is a
claim for assessment, not automatic evidence of entitlement. The original
estimate is not necessarily the quantity executed, and averaging disputed
quantities does not establish the actual contractual measurement. Accurate
measurement and appropriate supporting records are therefore fundamental to the
valuation.
17. A Quantity
Surveyor notices that the estimated cost of a proposed health centre is
increasing mainly because the building's gross floor area has increased during
design development. Which cost-control indicator should be examined first to
determine whether the change is proportionate?
A. The client's
preferred contractor
B. The number of tender documents printed
C. The project cost per unit of floor area
D. The contractor's previous annual turnover
Answer: C
Rationale: When floor area changes significantly,
cost per square metre provides a useful high-level indicator for examining
whether the increase in total estimated cost is broadly proportionate to the
additional accommodation. It does not replace detailed cost analysis, but it
can quickly identify whether the developing estimate is moving outside a
reasonable range compared with the original budget or appropriate benchmarks.
Contractor turnover, document quantities and contractor preference do not
directly measure the relationship between building size and estimated
construction cost.
18. A client
requests a preliminary estimate for a proposed LGA office complex before
detailed drawings are available. The Quantity Surveyor has reliable cost data
from recently completed projects of comparable type. Which factor would be most
important when applying the historical cost data?
A. Adjust for
differences in size, location, specification, time and other relevant factors
B. Use the previous project's final cost without any adjustment
C. Increase the previous cost by an arbitrary percentage to cover every
uncertainty
D. Select the lowest historical cost because it provides the best budget
Answer: A
Rationale: Historical project costs become useful
estimating evidence only after appropriate adjustments are made for differences
between the reference project and the proposed project. Factors such as
building size, location, specification, construction period, market conditions
and project characteristics can materially affect cost. Using an old cost
without adjustment can produce a misleading estimate, while an arbitrary
percentage does not provide a disciplined treatment of the relevant cost
differences.
19. A Quantity
Surveyor is preparing a tender estimate for a project where the contractor will
be required to maintain access to an operating public facility throughout
construction. Which cost consideration should receive particular attention?
A. Temporary
works, protection, access arrangements and possible productivity effects
B. The contractor's previous annual dividend payments and financial returns
C. The number of copies of the tender report submitted to management
D. The client's expenditure on unrelated public facilities
Answer: A
Rationale: Construction within or around an
operating public facility can create additional costs and logistical
constraints. Maintaining safe access may require temporary works, protection,
segregation, phased construction and modified working arrangements, while restricted
working areas may also affect productivity. These factors should therefore be
considered when preparing realistic rates, preliminaries and the overall
project estimate.
20. A Quantity
Surveyor is assessing a contractor's claim for additional work and discovers
that the contractor has already included the same work under another BOQ item
in the current valuation. What principle should guide the assessment?
A. Certify both
amounts because the work was physically completed
B. Certify whichever amount gives the contractor the higher payment
C. Remove both amounts until the final account is prepared
D. Avoid double counting and establish the correct contractual basis for
valuation
Answer: D
Rationale: A valuation should represent the
legitimate value of work without duplication. Where the same physical work has
already been included under another BOQ item, the Quantity Surveyor should
identify the correct contractual basis and ensure that the work is valued only
once. Certifying both amounts would overstate the project's financial liability
and could result in an unjustified payment.
21. A project
has an approved budget of TZS 1.5 billion. The latest forecast shows an
expected final cost of TZS 1.62 billion. Which statement best describes the
situation from a cost-control perspective?
A. The project
has a TZS 120 million forecast cost overrun against the approved budget
B. The project has saved TZS 120 million because the forecast is below tender
value
C. The project has no variance until the final account is agreed
D. The project has a TZS 120 million profit because the budget is not a
contract price
Answer: A
Rationale: The forecast final cost exceeds the
approved budget by TZS 120 million, calculated as TZS 1.62 billion minus TZS
1.50 billion. This represents a forecast cost overrun of TZS 120 million
against the approved budget and should trigger investigation and appropriate
cost-control action. The fact that the final account has not yet been agreed
does not prevent a forecast variance from being identified, and the budget is a
cost-control benchmark rather than a measure of contractor profit.
22. A Quantity
Surveyor is asked to prepare a short project report for management on the
financial status of an ongoing public building project. Which combination would
provide the most useful information for management decision-making?
A. Contractor's
company history, staff names and equipment photographs
B. Site attendance records, weather observations and workers' accommodation
details
C. Original budget, expenditure or certified value, forecast final cost and
significant variances
D. Architect's professional history, drawing titles and number of site meetings
held
Answer: C
Rationale: A management financial report should
communicate the project's financial position and highlight matters requiring
management attention. Comparing the original approved budget with expenditure
or certified work, forecast final cost and significant variances provides
decision-makers with meaningful information about cost performance and
potential financial risks. Site attendance, company history and meeting counts
may be relevant to other aspects of project management but do not by themselves
explain the project's financial position.
23. A
contractor's tender contains a mathematical error in the extension of one BOQ
item. The unit rate appears correctly entered, but the multiplication of
quantity by rate is incorrect. During tender examination, what should the
Quantity Surveyor do?
A. Ignore the
error because the contractor signed the tender form
B. Automatically reject the entire tender without considering the applicable
procedure
C. Replace the unit rate with the corrected extension to preserve the submitted
total
D. Apply the correction procedure specified by the tender conditions and
procurement requirements
Answer: D
Rationale: Arithmetic errors in tenders must be
treated according to the applicable tender conditions and procurement
procedures rather than corrected arbitrarily by the Quantity Surveyor. The
distinction between an erroneous extension and an incorrect unit rate can be
important because the applicable correction mechanism may differ. The fact that
a tender has been signed does not eliminate the need to deal with arithmetic
discrepancies, but neither does an arithmetic error automatically justify
rejecting the entire tender without following the prescribed procedure.
24. A public
construction project is approaching completion, and the Quantity Surveyor is
reviewing whether the final account can be prepared accurately. Several
approved variations have been implemented, but some supporting measurement
records are incomplete. What is the greatest immediate concern?
A. The contractor
may request additional office accommodation
B. The project architect may change the building's external colour
C. The final valuation may lack sufficient evidence to establish the correct
value of variations
D. The original project budget may become automatically invalid after practical
completion
Answer: C
Rationale: Proper supporting measurement and
valuation records are essential for establishing the financial value of
variations and preparing a defensible final account. If records are incomplete,
the parties may face difficulty determining the actual quantities, applicable
rates and contractual entitlement, increasing the risk of disagreement. The
other issues do not directly affect the evidential basis required to establish
the final value of variations.
25. A
contractor has submitted a claim for additional payment alleging that a design
change increased the quantity of masonry work. The Quantity Surveyor confirms
that the drawing was revised after the contract was awarded. What should be
established before determining the amount payable?
A. Whether the
contractor's original tender was the lowest among all tenderers
B. Whether the revised instruction constitutes a contractual change and how the
additional work should be valued
C. Whether the contractor has already purchased all materials required for the
revised work
D. Whether the contractor's current profit is sufficient to absorb the
additional work
Answer: B
Rationale: A post-contract design change may create
a contractual variation or another form of entitlement, but the Quantity
Surveyor must first establish the contractual status of the instruction and the
applicable valuation mechanism. This includes identifying the authorised
change, determining the additional quantity and applying the appropriate
contract rates or valuation principles. The contractor's original tender
ranking, its purchasing position and its profit level do not determine whether
the additional work is contractually payable or how its value should be
assessed.
26. A Quantity
Surveyor is measuring blockwork for a government office project. Openings such
as doors and windows occur within the wall. Which principle should primarily
guide the treatment of these openings?
A. Deduct
openings according to the applicable measurement rules and the size of each
opening
B. Deduct every opening regardless of its dimensions and construction
significance
C. Ignore all openings because the contractor still incurs labour around them
D. Deduct openings only after the contractor submits the final account
Answer: A
Rationale: Openings in measured work are treated
according to the applicable method of measurement, which normally specifies
when deductions are required based on dimensions and the nature of the work.
The purpose is to produce consistent and auditable quantities rather than
relying on arbitrary treatment. Ignoring openings or postponing all deductions
until the final account would distort interim quantities, while deducting every
opening regardless of the applicable rules would also produce inaccurate
measurement.
27. While
preparing a cost estimate, the Quantity Surveyor identifies a substantial risk
that the price of imported construction equipment may increase before
procurement. Which treatment would most appropriately reflect this risk in the
estimate?
A. Remove the
equipment from the estimate until the price becomes certain
B. Ignore the risk because market prices are outside the project's control
C. Assess the risk using an appropriate allowance or risk methodology
consistent with the estimating stage
D. Add an arbitrary amount to every BOQ item to compensate for the possible
increase
Answer: C
Rationale: Cost estimates should recognise
significant uncertainties using an appropriate risk and contingency approach
suitable to the project stage. The potential increase in imported equipment
cost should be assessed based on its likelihood, potential impact and the
information available rather than being ignored or addressed through an
arbitrary increase to every BOQ item. A disciplined allowance provides a more
transparent representation of uncertainty while avoiding unnecessary inflation
of unrelated costs.
28. A building
project has a preliminaries section containing site establishment, temporary
services, supervision and other project-wide costs. Why are such costs
generally treated separately from measured permanent works?
A. They are paid
only after practical completion
B. They relate to resources and obligations associated with managing and
executing the project as a whole
C. They are always supplied directly by the client rather than the contractor
D. They have no effect on the contractor's overall tender price
Answer: B
Rationale: Preliminaries generally cover costs
associated with establishing, managing, administering and supporting the
construction project as a whole rather than producing a specific measurable
permanent work item. Examples can include site facilities, temporary services,
supervision and compliance obligations, depending on the contract and project.
They therefore need appropriate identification and pricing because they form
part of the contractor's overall cost of performing the works.
29. A
contractor prices a BOQ item at TZS 85,000 per square metre. The Quantity
Surveyor's analysis indicates direct costs of TZS 70,000 per square metre. If
overheads and profit together are 15% of the direct cost, what is the
approximate total cost before considering any other project-specific
adjustments?
A. TZS 75,000 per
square metre
B. TZS 80,500 per square metre
C. TZS 85,000 per square metre
D. TZS 92,500 per square metre
Answer: B
Rationale: The direct cost is TZS 70,000 per square
metre. Fifteen percent of TZS 70,000 is TZS 10,500, giving a combined cost of
TZS 80,500 per square metre. The contractor's submitted rate of TZS 85,000 is
therefore higher than this simplified analysed cost, but that difference cannot
automatically be treated as excess profit because the simplified analysis may
exclude other relevant factors. The calculation illustrates how overheads and
profit can be incorporated into a basic rate build-up.
30. A
construction programme indicates that excavation must be completed before
foundation concrete can commence. The contractor proposes starting foundation
concrete while excavation is only partially complete by moving workers to
isolated sections. What should the Quantity Surveyor consider when assessing
the cost implications of this proposal?
A. Whether the
contractor's office is sufficiently close to the site
B. Whether the client's original budget contains an unused contingency
C. Whether the contractor has previously completed similar buildings
D. Whether the proposal changes resource requirements, sequencing or costs
under the contract
Answer: D
Rationale: Changes to construction sequencing can
affect labour, plant, productivity, temporary works, supervision, programme
duration and other costs. The Quantity Surveyor should therefore assess whether
the proposed approach changes the contractor's contractual obligations or
creates additional cost consequences. The contractor's experience and the
availability of unused contingency may be relevant to wider project management,
but neither automatically establishes the financial effect of a change in
sequencing.
