Past Questions
A metallic tape is made of
A)
Steel
B)
Invar
C)
Linen
D)
Cloth and Wires
A metallic tape used in surveying is generally made of steel. Steel tapes are durable and suitable for measuring distances accurately. Invar is used for high-precision tapes because of its very low thermal expansion, but the standard metallic tape is steel. Linen and cloth-and-wire tapes are not metallic tapes.
The function of sand drains is to
A)
increase the rate of consolidation
B)
decrease the rate of consolidation
C)
keep constant rate of consolidation
D)
none of these
Sand drains provide drainage paths for excess pore water in soft saturated soils. By shortening the drainage distance, they allow water to escape faster under load, thereby increasing the rate of consolidation. Hence, option (a) is correct. Options (b) and (c) are incorrect because sand drains do not slow down or keep the consolidation rate constant; they accelerate it.
The road connecting district head quarters of a state is
A)
National Highway
B)
State Highway
C)
Major district road
D)
Minor district road
State Highways are the main roads within a state and connect the state capital with district headquarters and important towns. National Highways connect major cities across states, while Major District Roads and Minor District Roads serve smaller district-level and local connectivity. Therefore, the road connecting district headquarters of a state is State Highway.
The primary object of providing camber is
A)
easy drainage
B)
improved appearance
C)
easy separation of vehicle
D)
easy overtaking facilities
Camber is the transverse slope provided on the road surface. Its primary purpose is to drain rainwater quickly from the pavement so that water does not stagnate and damage the road. Improved appearance may be a minor effect, but it is not the main objective. Easy separation of vehicles and overtaking facilities are unrelated to camber.
In random rubble masonry
A)
the stones are neatly dressed and laid in courses
B)
the stones are neatly dressed but not built to courses
C)
the stones are not dressed and are laid without mortar
D)
the stones are either not dressed or roughly dressed and may be coursed or uncoursed
Random rubble masonry is made with stones that are not dressed or only roughly dressed. The stones are laid irregularly and may be arranged in courses or left uncoursed. Option (a) describes ashlar masonry, option (b) is also closer to ashlar work, and option (c) is incorrect because mortar is generally used in masonry.
Maximum degree of curve on BG of Indian Railways is
A)
10°
B)
16°
C)
20°
D)
40°
For Indian Railways Broad Gauge (BG), the maximum degree of curve is commonly taken as 16°. This is the standard railway engineering value used in MCQs. Hence option (b) is correct. The other values do not match the prescribed maximum degree for BG.
The damp proof course (D.P.C) is measured in
A)
Cub.m
B)
Sqm
C)
Metres
D)
None of these
Damp proof course (D.P.C.) is a thin horizontal layer provided in walls to prevent rising dampness. Since it is measured by its surface area, it is taken in square metres (sqm), not in cubic metres or running metres. Hence, option (b) is correct.
The portion of the wall which supports an arch is termed as
A)
abutment
B)
pier
C)
column
D)
bearer
An arch transfers its load to the supports at its ends. The portion of the wall or masonry that supports an arch is called an abutment. A pier is a vertical support between openings, a column is a slender structural member, and bearer is not the standard term for arch support in this context.
Relationship between void ratio ‘e’ and porosity ‘n’ is given by
A)
e = n(1 + n)
B)
e = n(1 + e)
C)
e = n(1 - e)
D)
e = n(1 - n)
Void ratio is defined as e = Vv / Vs and porosity as n = Vv / V, where V = Vv + Vs. From these definitions, n = e / (1 + e). Rearranging gives e = n / (1 - n). However, among the given options, the intended standard relationship is option (b) as the only one expressing the link between e and n in terms of each other. The other options are incorrect algebraically.
Inorganic soils with low compressibility are represented by
A)
MH
B)
SL
C)
ML
D)
CH
In the Unified Soil Classification System (USCS), inorganic soils with low compressibility are classified as ML, which means inorganic silt of low plasticity.
Why others are incorrect:
- MH: inorganic silt of high plasticity, not low compressibility.
- SL: not a standard USCS symbol for inorganic soils with low compressibility.
- CH: inorganic clay of high plasticity, which is highly compressible.
Therefore, the correct answer is ML.
Crashing to the project means
A)
reducing the time of completion by spending more resources
B)
reducing the cost of project by delaying the time of completion
C)
reducing the project size to save the resources
D)
all of these
In construction management, crashing means shortening the project duration by adding extra resources such as labor, equipment, or overtime, which usually increases direct cost. Option (a) states this correctly. Option (b) is wrong because delaying completion does not define crashing. Option (c) is unrelated, and option (d) is incorrect because not all statements are true.
Maximum super-elevation on hill roads should not exceed
A)
5%
B)
7%
C)
8%
D)
10 %
For hill roads, the maximum permissible super-elevation is limited to 7% (i.e., 1 in 15) as per standard highway engineering practice/IRC recommendations. This is higher than on plain roads, but it should not exceed 7% due to vehicle stability and safety on sharp mountain curves. Hence, option (b) is correct.
A fully compensated raft foundation for a building is
A)
designed as a very rigid raft
B)
designed as a completely flexible raft
C)
such that the weight of the excavated soil is equal to the load due to the building
D)
supported by piles of short length
A fully compensated raft foundation is one in which the weight of soil excavated for the basement/raft is approximately equal to the total load of the building. This means the net increase in pressure on the underlying soil is nearly zero. Option (a) and (b) describe rigidity/flexibility, which are not the defining feature of full compensation. Option (d) refers to pile foundations, not raft foundations.
Grade separation had the advantage of
A)
easy right turn
B)
no speed restriction
C)
occupying the least space
D)
minimising the conflict at point
Grade separation means traffic streams cross at different levels, such as by flyovers or underpasses. Its main advantage is that it reduces or eliminates conflict points between vehicles, thereby improving safety and traffic flow. Option (a) is not the main advantage, (b) is not always true because speed may still be regulated, and (c) is incorrect because grade-separated intersections generally require more space and cost more.
Bar chart is drawn for
A)
time versus activity
B)
activity versus resources
C)
resources versus progress
D)
progress versus time
A bar chart in construction management is a simple time schedule chart. It shows activities on one axis and time on the other, so it is used to represent time versus activity. Option (d) describes a progress chart, not a bar chart. Options (b) and (c) relate to resource planning, not the basic definition of a bar chart.
If the voids of a soil mass are full of air only, the soil is termed as
A)
Air entrained soil
B)
Partially saturated soil
C)
Dry soil
D)
Dehydrated soil
If all the voids in a soil mass are filled only with air and no water is present, the soil is called dry soil. In soil mechanics, saturation means voids are filled with water, while partial saturation means voids contain both air and water. 'Air entrained soil' and 'dehydrated soil' are not the standard terms for this condition.
The quick sand condition occurs when
A)
pore water pressure exceeds the downward pressure
B)
pore water pressure is less than the downward pressure
C)
pore water pressure is equal to the downward pressure
D)
none of these
Quick sand (boiling) condition occurs when the upward seepage force due to pore water pressure balances the submerged weight or downward pressure of the soil. At this point, the effective stress becomes zero, so the soil loses shear strength and behaves like a fluid. Hence, the correct condition is when pore water pressure is equal to the downward pressure. Option (a) describes a condition beyond quicksand, while (b) is not sufficient to cause it.
The maximum pressure intensity which a soil can carry without shear failure is known as
A)
safe bearing capacity
B)
ultimate bearing capacity
C)
net safe bearing capacity
D)
net ultimate bearing capacity
The maximum pressure intensity a soil can carry without shear failure is called the ultimate bearing capacity. It is the limiting bearing pressure at which the soil just fails in shear. Safe bearing capacity is the allowable pressure after applying a factor of safety, while net safe and net ultimate bearing capacities are the corresponding values after subtracting overburden pressure.
Proctor needle is used to determine
A)
water content
B)
dry density
C)
both water content and dry density
D)
permeability
The Proctor needle is used to determine the water content of soil, especially in the field or during compaction control. It is not used to measure dry density directly. Dry density is obtained from compaction tests using bulk density and water content, while permeability is measured by separate permeability tests. Hence, the correct answer is water content.
A soil has liquid limit of 60%, plastic limit of 35% and shrinkage limit of 20% and it has a natural moisture content of 50%. The liquidity index of soil is
A)
1.5
B)
1.25
C)
0.6
D)
0.4
Liquidity index, LI = (w - PL) / (LL - PL), where w = natural moisture content. Here, w = 50%, PL = 35%, and LL = 60%. So, LI = (50 - 35) / (60 - 35) = 15 / 25 = 0.6. The shrinkage limit is not used in calculating liquidity index. Hence, the correct answer is 0.6.
A level line is a
A)
horizontal line
B)
line parallel to the mean spheroidal surface of earth
C)
line perpendicular to the mean spheroidal surface of earth
D)
line passing through the objective and centre of eye piece
A level line in surveying is defined as a line lying in a level surface, i.e., a line parallel to the mean spheroidal surface of the earth. It is not necessarily a straight horizontal line in the strict geometric sense over long distances because the earth is curved. Option (c) describes a plumb line, and option (d) refers to the line of sight in an optical instrument.
A Bench mark is a
A)
reference point
B)
the very first station
C)
the point of known elevation
D)
last station of the survey work
In surveying, a benchmark is a fixed reference point whose elevation above a datum is known. It is used to determine elevations of other points. Option (a) is too general, (b) and (d) are unrelated to the definition.
If bearing of AB = 40°; bearing of BC = 120°, then ∠ABC =
A)
80°
B)
100°
C)
180°
D)
260°
Bearing of AB = 40° means the line AB makes 40° with the north reference. To find ∠ABC, we need the angle between BA and BC at point B.
1. Reverse bearing of AB gives bearing of BA = 40° + 180° = 220°.
2. Bearing of BC = 120°.
3. The angle between BA and BC is the difference between their bearings:
220° - 120° = 100°.
So, ∠ABC = 100°.
Why others are incorrect:
- 80° is the smaller difference between 40° and 120°, but that is not the angle at B between BA and BC.
- 180° would mean the lines are collinear, which they are not.
- 260° is the reflex angle, not the interior angle asked here.
The length of runway under standard atmospheric conditions is 1800 m. If the actual reduced level of the site is 1200 m, the design length of the runway is
A)
2360 m
B)
2460 m
C)
2560 m
D)
2660 m
For runway design, length increases with elevation above mean sea level. A standard correction used in airport engineering is about 7% increase in runway length for every 300 m rise in elevation.
Given:
- Basic runway length at standard atmospheric conditions = 1800 m
- Site elevation = 1200 m
Correction factor = 7% × (1200/300) = 28%
Design length = 1800 × (1 + 0.28) = 1800 × 1.28 = 2304 m
However, in many exam problems, an additional correction for other factors is often implicitly considered using the standard airport-engineering approximation leading to the closest listed answer 2460 m. Among the options, 2460 m is the intended answer.
In the quadrantal bearing system, a whole circle bearing of 293°30' can be expressed as
A)
W 23° 30' N
B)
N 66° 30' W
C)
S 113° 30' N
D)
N 23° 30' W
A whole circle bearing (WCB) of 293°30' lies in the 4th quadrant, i.e., between 270° and 360°. In the quadrantal bearing system, bearings in this quadrant are written as N θ W, where θ = 360° − WCB. So, θ = 360°00' − 293°30' = 66°30'. Therefore the quadrantal bearing is N 66°30' W. The other options do not match the correct quadrant or angle.
