Question 1

Interpret Figures Q1.1 to Q1.4, Tables Q1.1 and Q1.2 and apply measurement techniques to:

Specification Notes for Pile Caps:

• Excavation work shall commence from EGL.
• Reinforce concrete shall be of grade 35.
• There is a layer of 75 mm thick grade 15 lean concrete below each pile cap.
• Formwork shall be of sawn timber.
• First storey slab and ground beams are NOT to be measured.
• Concrete cover shall be 50 mm thick.
• Laps for binders shall be 1250 mm (3N1) and 450 mm (2L1 & 2N1).

Specification Notes for Bored Piles:

• Reinforced concrete shall be of grade 35. Concrete cover shall be 75 mm thick.
• Working load test shall be executed on one 1800 mm diameter piles up to 1.5 times the designed working load of the pile (1200t) and one 700 mm diameter piles (300t).
• Pile integrity test is to be executed on three selected piles.
• All empty bores shall be fill up with imported sand.
• Pile reinforcement shall be as follows:

(a) Take-off quantities for excavation, concrete and formwork for all the pile caps. (15 marks)

(b) Take off quantities for the reinforcement work. (15 marks)

(c) Take off quantities for the bored piles. (15 marks)

Question 2

Figures Q2.1 to Q2.3 shows the construction of a deep shaft. The slab is cast in-situ and the rest of precast components.

Specification Notes:

• Excavation works shall commence from the top level as indicated in the drawings.
• Precast concrete components shall be in grade 40.
• Formwork shall be sawn timber.
• Concrete cover shall be 50 mm thick.
• Holes in shaft wall for steel pipe penetration shall be cut on site during installation.
• All pipes are NOT to be measured.

(a) Identify and describe the relevant SMM clauses required for measuring the precast concrete work. (5 marks)

(b) Take-off quantities for the shaft.(10 marks)

Question 3

Identify the scope and interpret the Figures Q3.1 to Q3.5 and Table Q3.1.

Specification notes:

• Reinforced concrete shall be of grade 30
• Formwork shall be of wrot timber

Prepare a take-off list with the corresponding SMM clauses and the units of measurement for measuring the stairs, suspended beams and landing slab including reinforcement. (10 marks)

(a) Apply measurement techniques to take off quantities for the reinforced concrete and formwork to the stairs, landing and suspended beams.

(10 marks)

(b) Take-off quantities for the staircase, landing and beam reinforcement. (Note: Assumptions made for calculating the length of the bars must be clearly indicated).
