Problem 1

A transition section is part of a project where:

a) Elevations change from positive to negative

b) There is a change in elevation

c) A project changes from fill to excavation

d) A project changes from excavation to fill

e) (c) or (d)

f) (a), (b) and (c)

Problem 2

A batter board is used to provide:

a) Horizontal alignment for excavations

b) Horizontal alignment for construction

c) Elevations for excavations

d) Elevations for construction

e) Protection against falls of personnel

f) Comfortable seating

g) (a) to (d)

h) (a) to (e)

Problem 3

b) Create an overall reference frame for a project

c) Only provide horizontal coordinates

d) (a), (b) and (c)

e) (a) and (b)

Problem 4

b) Establish horizontal planes

c) Establish the shape of the shore

d) Look for sunken treasure

e) Establish the shape of the bottom of a water body

Problem 6

Which of the following are uses for stakes?

a) Line, slope, cut

b) Offset, grade point, marker

c) Line, cut, grade point

d) All of the above

Problem 7

Tunnel surveys are:

a) Two-dimensional

b) Three-dimensional

c) Use a coordinate system

d) (a) and (c)

e) (b) and (c)

Solution

1.(e) a transition section is a part of project where the project changes from fill to excavation or excavation to fill.

2. (g) batter boards are used to proper alignment of construction works . They help in avoiding personal mistakes from happening in alignment.

3. (e) project survey control points are used to create a framework around which other survey can be adjusted. They are used in tunnels, roadways, power lines, many other high precision works.

4.(b). A line stake is used to provide a tie to construction line. They help in keeping the stations in position.

5.(e) hydrographic surveys are used to find the bottom of water bed there by helping in finding the shape of water body.

7.(e) tunnel survey is a 3D work where we use coordinate system.
