22301 Advanced Surveying Viva Questions with Answers
Question 1. What Is Surveying?
Answer :
The profession or work of examining
and recording the area and features of a piece of land so as to construct a
map, plan, or detailed description of it.
Question 2. What Is A Surveyor?
Answer :
Surveyors update boundary lines and
prepare sites for construction so that legal disputes are prevented. Surveyors
make precise measurements to determine property boundaries. They provide data
relevant to the shape and contour of the Earth's surface for engineering,
mapmaking, and construction projects.
Question 3. What Is A Property
Surveyor?
Answer :
It is important, therefore, that you
employ a surveyor yourself to undertake a thorough inspection of the property you
wish to buy. The types of surveys available. There are two main types of
structural survey available for those buying a property: a Homebuyer's Report
or a Full Building Survey.
Question 4. What Is A Marine
Surveyor?
Answer :
A Marine surveyor (including
"Yacht & Small Craft Surveyor", "Hull & Machinery
Surveyor" and/or "Cargo Surveyor") is a person who conducts
inspections, surveys or examinations of marine vessels to assess, monitor and
report on their condition and the products on them, as well as inspects damage
caused to both vessels .
Question 5. What Is An Automatic
Level?
Answer :
A dumpy level, builder's auto level,
leveling instrument, or automatic level is an optical instrument used to
establish or verify points in the same horizontal plane. It is used in
surveying and building with a vertical staff to measure height differences and
to transfer, measure and set heights.
Question 6. What Is The Use Of Dumpy
Level?
Answer :
A dumpy level is a surveying tool
that measures horizontal lines. It is used to determine relative height and
distance among different locations. In modern times, it is most commonly used
to obtain measurements for buildings rather than to gather information on large
tracts of land.
Question 7. What Does It Mean To
Survey A Boat?
Answer :
Basically, it is a detailed
inspection of a boat, hopefully done by a qualified, diligent, intelligent and
honest surveyor, for the purpose of determining its current condition and
seaworthiness.

Members and Fellows of the RICS
entitled to use the designation (and a number of variations such as
"Chartered Building Surveyor" or "Chartered Quantity
Surveyor" or "Chartered Civil Engineering Surveyor" depending on
their field .
Question 9. What Is A Level Staff?
Answer :
A level staff, also called levelling
rod, is a graduated wooden or aluminum rod, used with a levelling instrument to
determine the difference in height between points or heights of points above a
datum surface.
Question 10. What Is A Transit Tool?
Answer :
A transit level is an optical
instrument, or a telescope, complete with a built-in spirit level that is
mounted on a tripod. Transit levels are used mainly for surveying and building,
but they can be used to determine the relative position of lines and objects as
well.
Question 11. What Is An Abney Level
Used For?
Answer :
An Abney level and clinometer, is an
instrument used in surveying which consists of a fixed sighting tube, a movable
spirit level that is connected to a pointing arm, and a protractor scale.
Question 12. What Is A Total Station?
Answer :
A Total Station is a modern surveying
instrument that integrates an electronic theodolite with an electronic distance
meter. A theodolite uses a movable telescope to measure angles in both the horizontal
and vertical planes.
Question 13. What Is Meant By
Hydrographic Survey?
Answer :
Hydrographic survey is the science of
measurement and description of features which affect maritime navigation,
marine construction, dredging, offshore oil exploration/offshore oil drilling
and related activities.
Question 14. How Long Does It Take To
Become A Chartered Surveyor?
Answer :
Most states require a degree along
with an internship, to become a professional land surveyor. Most degrees are a
four year college degree in surveying or geomatics or a 2 year associate
degree. After college you then have to become licensed in whichever state you
want to practice surveying in.
Question 15. How Does A Theodolite
Work?
Answer :
A theodolite works by combining optical
plummets (or plumb bobs), a spirit (bubble level), and graduated circles to
find vertical and horizontal angles in surveying. An optical plummet ensures
the theodolite is placed as close to exactly vertical above the survey point.
Question 16. What Is A Surveyor's
Transit?
Answer :
A vernier compass has an adjustable
scale that allows for the "setting off" of the magnetic declination
and the compass can then directly read true north. The Transit and Theodolite.
Transit. Theodolite. The transit and theodolite are used by the surveyor to
measure both horizontal and vertical angles.
Question 17. What Is An Optical
Square?
Answer :
An optical square is a square
refracting block which refracts an incident beam at an angle of 90 degrees.It
can be used with an autocollimator for measuring squareness of a workpiece.
Question 18. What Is An Edm In
Surveying?
Answer :
A total station or TST (total station
theodolite) is an electronic/optical instrument used in modern surveying and building
construction. The total station is an electronic theodolite (transit)
integrated with an electronic distance meter (EDM) to read slope distances from
the instrument to a particular point.
Question 19. What Is A Digital
Theodolite Used For?
Answer :
In addition to measuring horizontal
and vertical angles, digital theodolite are used to establish straight lines,
to establish horizontal and vertical distances through the use of stadia, and
to establish elevations when used as a level.
Question 20. What Is A Bathymetric
Survey?
Answer :
Bathymetry is the study of the
"beds" or "floors" of water bodies, including the ocean,
rivers, streams, and lakes. The term "bathymetry" originally referred
to the ocean's depth relative to sea level, although it has come to mean
“submarine topography,” or the depths and shapes of underwater terrain.
Question 21. What Is An Intermediate
Survey?
Answer :
Intermediate Survey—The inspection of
a vessel by a classification society surveyor which takes place between two and
three years before and after each Special Survey for such vessel pursuant to
the rules of international conventions and classification societies.
Question 22. What Is The Rics?
Answer :
The Royal Institution of Chartered
Surveyors (RICS) is a professional body that accredits professionals within the
land, property and construction sectors worldwide. Members holding RICS
qualifications may use the following designations after their name: MRICS
(Member), FRICS (Fellow), AssocRICS (Associate).
Question 23. What Is The Apc?
Answer :
The APC – assessment of professional
competence – is the training scheme that graduates need to complete on the job
to qualify as a chartered surveyor. Becoming chartered with the Royal
Institution of Chartered Surveyors (RICS) is a key milestone in a surveyor's
professional development.
Question 24. What Is A Graphometer?
Answer :
The graphometer, semicircle or
semicircumferentor is a surveying instrument used for angle measurements. It
consists of a semicircular limb divided into 180 degrees and sometimes
subdivided into minutes. The limb is subtended by the diameter with two sights
at its ends.
Question 25. What Is The Basic Principle
Of Chain Surveying?
Answer :
Chain surveying is the type of
surveying in which only linear measurements are made in the field. The main
principle of chain surveying or chain triangulation is to provide a framework
consist of number of well-conditioned triangles or nearly equilateral
triangles. It is used to find the area of the field.
Question 26. What Is The Chain
Survey?
Answer :
Chain survey is the simplest method
of surveying. In this survey only measurements are taken in the field, and the
rest work, such as plotting calculation etc. are done in the office. This is
most suitable adapted to small plane areas with very few details.
Question 27. What Is The Tool
Surveyors Use?
Answer :
The main surveying instruments in use
around the world are the theodolite, measuring tape, total station, 3D
scanners, GPS/GNSS, level and rod. Most instruments screw onto a tripod when in
use. Tape measures are often used for measurement of smaller distances.
Question 28. What Is A Chartered
Surveyor?
Answer :
Chartered surveyors in the core of
the profession may offer mortgage valuations, homebuyer's survey and
valuations, full building surveys, building surveyors' services, quantity
surveying, land surveying, auctioneering, estate management and other forms of
survey- and building-related advice.
