This set of Basic Civil Engineering Multiple Choice Questions & Answers (MCQs) focuses on “Basic Surveying Terms”.
1. How many types of bench mark are there?
Explanation: Bench mark is an object bearing a marked point whose elevation above or below a datum is known. The 2 types are the temporary and permanent bench mark.
2. The difference between magnetic north and geographic north is:
Explanation: Declination is determined using the compass. The error is calculated and the necessary addition or deduction is carried out.
3. In the triangulation method, the whole area is divided into:
a) Scale triangles
c) Obtuse triangles
d) Well-conditioned triangles
Explanation: Well-conditioned triangles are those triangles with an angle less than or equal to 60o. The plot is divided into such triangles, as it is the easiest figure that can be plotted and analysed.
4. A stone that marks boundary is called:
Explanation: If a stone is used to mark a boundary, it is called Merestone. If a tree is on the property line, it is called a Line tree.
5. Which of the below is not a classification of surveying?
Explanation: Based on place of survey, the classification includes land, marine and astronomical categories. Basement refers to underground, no survey is performed there.
6. EDM stands for:
a) Errorless Distance Measurement
b) Electronic Direct Measurement
c) Electronic Distance Measurement
d) Errorless Direct Measurement
Explanation: To locate points, measure angles, distance and perform other surveying operations, an EDM can be used. It gives all the details with a click of button. Total station is an example of EDM.
7. Plane and geodetic surveying are classifications of surveying based on:
b) Earth’s curvature
c) Object of survey
Explanation: Based on Earth’s curvature to be considered or not while surveying, plane and geodetic surveying are there. Earth’s curvature is considered in geodetic and not considered in plane surveying.
8. _________ errors are small unavoidable fluctuation.
Explanation: Those errors which are made while performing survey are called gross errors. These can accumulate and finally lead to re-doing the whole procedure. Systematic error follows a consistent pattern.
9. Plan is a small-scale representation of a large area.
Explanation: Map is a small-scale representation of a large area. Plan is a large-scale representation of a small area.
10. Which of the below is not a means of linear surveying methods?
Explanation: Theodolite is an instrument used to measure angular readings. It is used in angular surveying. All other options are used to take linear measurements.
11. The term Gore is used to indicate:
a) Rectangular land
b) Perimeter of a land
c) Thin triangular land
d) A measure of distance
Explanation: Gore is a thin triangular piece of land. Metes and bounds are used to describe the perimeter of the parcel of land. Mete is a measurement of distance.
12. An acre is equal to 107,639 square feet.
Explanation: An acre is equal to 43,560 square feet. A hectare is equal to 2.471 acres or 107,639 square feet.
