• 0.5 men
• 1 man
• 2 men
• 1.5 men

Answer explanation

Felling trees is measured in:

• Each
• m²
• m³
• cm

Answer explanation

Felling measured as units per tree, so 'Each' is appropriate.

Girth of a tree is taken at a height of:

• 1 m
• 0.5 m
• 1.5 m
• 2 m

Answer explanation

Payment for earthwork excavation is made per:

• 1 m³
• 10 m³
• 100 m³
• m²

Answer explanation

Payment based on volumetric excavation units; 10 m³ per schedule.

Initial lead for excavation is:

• 50 m
• 30 m
• 100 m
• 60 m

Answer explanation

Horizontal distance from excavation to deposition site = 50 m (initial lead).

Initial lift for excavation is:

• 1.5 m
• 2.0 m
• 1.0 m
• 0.5 m

Answer explanation

Vertical distance taken for single lift = 1.5 m (initial lift).

Lift is defined as:

• Vertical distance
• Horizontal distance
• Area of excavation
• Volume of earth

Answer explanation

Lift = vertical distance moved by soil; defined in excavation terminology.

Lead in earthwork refers to:

• Horizontal distance
• Vertical distance
• Depth of trench
• Volume of soil

Answer explanation

Lead = horizontal distance from dig point to deposition

For open well > 3.5 m diameter, the additional lift is:

• 10%
• 15%
• 20%
• 25%

Answer explanation

Extra effort for wide wells increases lift cost by 10% when diameter > 3.5 m.
