Question 1

Identify the relevant SMM clauses and describe what is deemed to be included in the description and measurement of precast reinforced concrete piles and pile tests.

Question 2

Interpret Figure Q2 and apply measurement techniques to take-off quantities for the:

(a) Reinforced concrete columns and roof beam including formwork.
(b) Reinforcement in the roof beam.

Specifications:

• Reinforced concrete shall be of grade 35 strength
• Formwork used shall be of wrote timber
• Roof slab shall be 150mm thick. Concrete cover shall be 30mm thick

• All main steel reinforcement bars shall be of high tensile steel. Stirrups shall be of mild steel
• Minimum bend allowance shall be 150mm long. Hook allowance for links and
  stirrups shall be 24 times the diameter of the bar size

Question 3

Figures Q3.1 and Q3.2 show the plan and section of a brick load-bearing wall structure. Interpret scope and identify the civil and structural works. Apply measurement technique to take off quantifies for:

(a) Excavation work and disposal of excavated materials off-site.
(b) Strip foundation, Concrete slab, formwork, brick wall, hardcore, and including excavation adjustment. (Note: Brick wall is measured up to the existing ground level).
