SECTION B – SHORT QUESTIONS Question B3
The following is an extract from the preambles on Prime Cost rates (herein referred to as
“PC rate”):
“Where prime cost rates are included in the description of items in these Bills of
Quantities, these prime cost rates are for the material cost of that item delivered to site
( street level ) only and the Main Contractor shall allow in addition for all wastage, fixing,
all ancillary materials ………… The contract rate will be adjusted by the net difference
between the prime cost rate and the actual price (supply cost) and will be applied to
the net quantity of the items measured as fixed in position.”
Based on the rules of adjustment of PC rate above and the attached Bills of Quantities
(refer to Attachment for Question B3), please answer the following questions.
(a) For tiling (Finish F6), the actual supply tiling confirmed is “Barby” homogeneous
tiling at a supply cost of $260/m2, what is the revised unit rate of homogeneous
floor tiling (Finish F6) after adjustment of the PC rate? [2 marks]
(b) What is the amount of saving or extra expense as a result of the adjustment of the
PC rate in Item (a) above and based on the quantities as stated in the Bills of
Quantities of homogeneous floor tiling (Finish F6)? [2 marks]
(c) After the adjustment of the above PC rate item, an Architect’s instruction is given for
Room X with floor finishes changed from F3 to F6. The measured floor area of

SECTION C1 – QUESTIONS ON MEASUREMENT (TOTAL 56 MARKS)
The Owner of a recreation centre intends to build an extension. The Architect has
produced the architectural plans (Drawing A-01 and A-02). The Structural Engineer has
produced the framing plans (Drawing S-01 and S-02) but the reinforcement details are
not yet finalised. Previously during preliminary design stage, the Structural Engineer has
provided indication of steel ratio as follows:
(i) Ground slab – 150 kg/m3
(ii) Column and beam – 200 kg/m3
(iii) Roof slab – 100 kg/m3
(iv) Curb – 100 kg/m3
As the Owner wants to have the extension built and completely fitted out before next
summer, he would like to invite some contractors to tender for the works now and
requests his Quantity Surveyor to prepare Bills of Quantities based on the drawings
produced.
You are the project quantity surveyor and responsible for producing the Bill of Concrete
Works.
(a) Based on the structural drawings (Drawing S-01 & S-02) provided, prepare a
take-off list (items that need to be measured) for concrete and formwork. [8 marks]
(b) Your senior quantity surveyor has spotted some discrepancies in the architectural
and structural drawings. Please prepare tender queries to the Architect and the
Structural Engineer to clarify the discrepancies before taking off. [4 marks]
(c) Take off concrete and formwork based on Drawing S-01 & S-02. [27 marks]
(d) Based on the steel ratio given by the Structural Engineer, your senior asks you to
calculate the total approximate quantity of reinforcement. [7 marks]
(e) Prepare Bills of Quantities for Concrete Works (concrete and formwork only). Use
bill papers to answer this question. Each bill item shall include descriptions of work,
unit and quantity. Your senior has provided some sample bills of Concrete Works (2
pages) for your reference. [10 marks]
Attachment to Question C1:
1) Architectural Drawing A-01 and A-02
2) Structural Drawing S-01 and S-02
3) Sample Bills of Quantities – Concrete Works (2 pages)
