## Estimating and Costing In case of laying gullies, siphons, intercepting traps, the cost includes

Setting and laying
Connection to drains
All of these
Bed concreting

1000 m3
500 m3
1500 m3
2000 m3

## Estimating and Costing The 'centre line method' is specially adopted for estimating

Octagonal buildings
All of these
Hexagonal buildings
Circular buildings

## Estimating and Costing If the formation level of a highway has a uniform gradient for a particular length, and the ground is also having a longitudinal slope, the earthwork may be calculated by

Mid-section formula
Trapezoidal formula
Prismoidal formula
All of these

## Estimating and Costing In the mid-section formula

All of these
The area of mid-sections is calculated by using mean depth
The volume of the earth work is calculated by multiplying the mid-section area by the distance between the two original sections
The mean depth is the average of depths of two consecutive sections

## Estimating and Costing While preparing a detailed estimate

Volume should be measured correct to 0.01 cum
Dimension should be measured correct to 0.01 m
All of these
Area should be measured correct to 0.01 sqm
