Question 1

With reference to Figure Q1.1,
(a) Prepare a take-off list with the corresponding CEMS clauses and unit of measurement for measuring the excavation and reinforced concrete work.

(b) Apply measurement techniques to take off quantities for the excavation and reinforced concrete works.

Specifications:

(i) All excavation work shall commence from the existing ground level.
(ii) Lean concrete shall be of grade 15 and 75 mm thick.
(iii) The raft foundation slab shall be 400 mm thick.
(iv) All reinforced concrete shall be of grade 30.
(v) Formwork shall be of sawn timber.
(vi) Reinforcement for raft foundation slab shall consist of two layers of Fabric Mesh type A393 weighing 6.16 kg/m 2
(vii) Concrete cover is 50 mm thick

Question 2

(a) Compare the difference between a trial pile and a working pile and the different types of static load tests applied to them.

(b) With reference to Figure Q2.1, prepare a take-off list with the corresponding CEMS clauses and units of measurement for measuring reinforced concrete bored piles including reinforcement.

(c) With reference to Figure Q2.1, apply the measurement technique to take off quantities for the reinforced concrete bored piles.

(d) With reference to Figure Q2.1, apply the measurement technique to take off quantities for the reinforcement work.

Specification for Piling:

(i) All reinforced concrete bored piles shall be 1100 mm in diameter, of grade 35 concrete, and reinforced with 22 H28 mm diameter main bars and H12 mm diameter circular links @ 250 mm centers.
(ii) The estimated bored depth of piles is taken from the existing ground level.
(iii) All piling operations shall commence from the existing ground level.
(iv) Maintained working load test shall be executed on two piles up to 1.5 times the designed working load of 220 tonnes.
(v) Concrete cover shall be 75 mm thick.
(vi) Assume 50 working piles to be installed.
(vii) Rock is encountered at the last 500 mm depth of boring.

Question 3

With reference to Figure Q3.1, identify the scope and interpret the drawing.
(a) Identify the relevant CEMS rules relating to sub-heading and classification
requirements and explain how they are applied to the measurement of the steel roof trusses which do not form a major part of the structure.

(b) Apply measurement technique to take-off quantities for the steel roof truss.
