Part B -

CRFG engaged by the Fiji Government to upgrade the Princes road which is a 50million Project and 3 years Contract You were recruited as Civil engineering Technician for China Railway First Group (CRFG) and you are assigned to carry out the following

1. Draw a site layout of your site office. (Location)

2. Prepare a Typical Cross Section of the road (Cut & fill)

3. Work Program (Gant Chart)

4. Bill of Quantities

Part C

Question 1

A sandy clay soil being excavated from a road cutting and re-used for fill has the following characteristics:

Bank density = 1600kg/m³

Loose Density = 1250kg/m³

Compacted Density = 2000kg/m³

Find the Load Factor (I), the shrinkage (%), and what volume 152,000Lm³ would be after compaction

Question 2

Find the swell for a soil which weighs 1600kg/m in bank and 1300kg/m³ in bank and 1300kg/m³ Loose.

Question 3

What is the shrinkage factor for a mass of soil that takes up 1.5m³ in bank and reduces down to 1.2m³ after compaction

Question 4

Calculate the Load Factor for clay if the percentage swell from the bank state is 25%.

Question 5

If a mass of soil reduces volume by 23% from the bank condition after compaction then what is the shrinkage factor
