Plaster work is measured in
A)
Cum.
B)
Sqm.
C)
Rm.
D)
None of these
Plaster work is measured by surface area, since it is applied as a thin layer over walls, ceilings, etc. Therefore, the correct unit is square metre (Sqm.). Cum. is used for volume measurements, and Rm. is used for length measurements. Hence, option (b) is correct.
The unit of measurement is per quintal for the following item
A)
Collapsible gates with rails
B)
Rolling shutter
C)
Expanded metal wire netting
D)
Reinforcement of R.C.C. works
In estimation and costing, expanded metal wire netting is measured by weight, and the unit of measurement is commonly per quintal. Collapsible gates and rolling shutters are usually measured in square metres or by area, while reinforcement in R.C.C. works is measured in kilograms or quintals depending on the schedule, but the standard item specifically associated with per quintal here is expanded metal wire netting.
In Water bound macadam roads, binding material is
A)
Sand
B)
Soil
C)
Stone dust
D)
Brick dust
In Water Bound Macadam (WBM) roads, the binding material used to fill the voids between the coarse aggregates is usually stone dust (also called screenings or binding material). It helps interlock the aggregate layer and provides a dense surface. Sand and soil are not suitable as standard WBM binding materials, and brick dust is not the usual binding material in WBM construction.
Raising outer edge of the road with respect to inner edge on curve is known as
A)
Cant
B)
Banking
C)
Super elevation
D)
All of these
On a horizontal curve, the outer edge of the road is raised above the inner edge to counteract the centrifugal force. This is called super elevation, and it is also commonly referred to as cant or banking. Since all three terms mean the same thing in highway engineering, the correct answer is 'All of these'.
Which one of the following gases is most significant as air pollutant
A)
Carbondioxide
B)
Oxygen
C)
Nitrogen
D)
Sulphurdioxide
Sulphur dioxide is a major air pollutant because it is released from the burning of sulfur-containing fuels and industrial processes. It irritates the respiratory system and contributes to acid rain and smog. Carbon dioxide, oxygen, and nitrogen are natural components of air and are not considered significant air pollutants in this context.
Substituted item is
A)
an item executed but not included in the agreement
B)
an item executed in excess of original agreement quantities
C)
an item executed in place of other similar item having different specification and rates
D)
an item which was not required to be executed.
A substituted item is one that replaces an originally specified item during execution, usually because of a change in specification, design, or material, and it is paid at a different rate. Option (a) refers to extra/non-agreement items, option (b) refers to excess quantities, and option (d) is not a standard contract term.
Extension of time can be granted if
A)
the contractor fails to complete the work in time due to his slow progress
B)
the contractor neglect his work and do not completed work in time
C)
there is a compensation events as per contract agreement
D)
there is long and heavy monsoon rain.
Extension of time is granted when delay occurs due to reasons covered under the contract, such as compensation events, employer-caused delays, changes in scope, or other permissible causes. Slow progress or negligence by the contractor are not valid grounds for extension. Heavy monsoon rain may sometimes justify extension only if specifically recognized by the contract and shown to be exceptional, but the best and most correct option here is the contractual compensation event.
Surveying Metric Chains are available in length of:
A)
15m and 30m
B)
20m and 30m
C)
10m and 20m
D)
30m and 50m
Metric chains used in surveying are commonly manufactured in standard lengths of 20 m and 30 m. The 20 m chain is often used for smaller surveys, while the 30 m chain is more common in engineering and cadastral surveys. The other options list non-standard lengths for metric chains.
One Chain link measures:
A)
30cm
B)
20cm
C)
15cm
D)
10cm
In surveying, a standard metric chain is made up of links, and each chain link measures 0.20 m = 20 cm. Therefore, the correct answer is 20 cm. The other options do not match the standard surveying chain link length.
The pavement width of road is depends upon
A)
Terrain
B)
Types of traffic
C)
Nos. of lanes
D)
Formation width
Pavement width is mainly governed by the number of lanes required for traffic movement. As the number of lanes increases, the carriageway/pavement width increases accordingly. Terrain affects alignment and design speed, types of traffic affect pavement thickness and composition, and formation width is the overall roadbed width, but the direct basis for pavement width is the number of lanes.
Contingencies provided in an estimate is
A)
provision for quality control works
B)
provision for staff salary
C)
provision to meet unforeseen expenditure in execution the work
D)
none of these
In estimation and costing, contingencies are an additional percentage amount kept in the estimate to cover unforeseen items or expenses that may arise during execution of the work. It is not meant for staff salary or quality control works specifically. Therefore, option (c) is correct.
If the thickness of a structural member is small as compared to its length and width, it is classified as
A)
one dimensional
B)
two dimensional
C)
three dimensional
D)
none of these
A structural member whose thickness is very small compared to its length and width is treated as a planar or two-dimensional member, because variation through the thickness is neglected in analysis. One-dimensional members are typically bars/rods where only length is significant, while three-dimensional bodies have all dimensions comparable.
Arrange the words given below in a meaningful sequence: 1. Police 2. Punishment 3. Crime 4. Judge 5. Judgement
A)
3, 1, 2, 4, 5
B)
1, 2, 4, 3, 5
C)
5, 4, 3, 2, 1
D)
3, 1, 4, 5, 2
The logical sequence is: Crime → Police → Punishment → Judge → Judgement. First a crime is committed, then the police investigate/arrest, punishment follows through the legal process, the judge gives the decision, and finally judgment is delivered. So the correct arrangement is 3, 1, 2, 4, 5.
Cost indices is generally work out when
A)
New Schedule of rate (SOR) is issued
B)
When the contractor rate is low
C)
When the market rate is going up or down but new SOR is not yet ready.
D)
None of these
Cost indices are used to adjust estimated costs when market prices change but an updated Schedule of Rates (SOR) has not yet been issued. They help account for inflation or variation in material/labour rates. Option (a) is incorrect because if a new SOR is issued, that itself provides the updated rates. Option (b) is unrelated. Therefore, the correct answer is (c).
The brick work is not measured in cum. in case of
A)
One or more than one brick thick wall
B)
Brick work is an arch
C)
Reinforced brick work
D)
Half brick work
Brickwork is generally measured in cubic metres (cum) for walls of one brick thickness or more, and also for arches and reinforced brickwork as their volume matters. However, half-brick work is an exception and is usually measured in square metres because its thickness is uniform and small, so volume measurement is not convenient. Therefore, the correct answer is Half brick work.
The slenderness ration of a column is zero when its length
A)
is zero
B)
is equal to its radius of gyration
C)
is supported on all side throughout its length
D)
is between the points of zero moments
Slenderness ratio of a column is defined as \(\lambda = \frac{L_e}{r}\), where \(L_e\) is the effective length and \(r\) is the radius of gyration. For the slenderness ratio to be zero, the effective length must be zero, which means the column length is zero. The other options do not make the ratio zero: equal to radius of gyration gives \(\lambda = 1\), support on all sides reduces buckling but not necessarily to zero, and points of zero moments are unrelated to making the ratio zero.
Diameter of rivet hole is made larger than the diameter of the rivets by
A)
1 mm for rivet diameter up to 12mm.
B)
1.5 mm for rivet diameter exceeding 25mm.
C)
2.0 mm for rivet diameter over 25mm.
D)
none of these
In steel structures, the rivet hole is made slightly larger than the rivet diameter to allow easy insertion. The usual clearance is 1.5 mm for rivets up to 25 mm diameter and 2.0 mm for rivets over 25 mm. Therefore, among the given options, the correct statement is that the hole is larger by 1.5 mm for rivet diameter exceeding 25 mm only if the question intended the standard clearance list, but the precise standard for 'exceeding 25 mm' is actually 2.0 mm. Since option (c) states 2.0 mm for rivet diameter over 25 mm, that is the correct engineering rule. However, because the question asks for the single correct option and the listed choices include the standard value, the correct option is (c).
The Unit of tack coat in bituminous pavement work is taken as sqm. because
A)
It is a surface work
B)
It is a bituminous work
C)
The thickness is very small to measure
D)
All of these
Tack coat is measured in square metres because it is applied as a thin surface treatment over an area, not as a work measured by volume or thickness. The key reason is that it is a surface work. Option (c) is not the main justification, and (b) is too general. Hence, the correct answer is (a).
The expected out turn of half brick partition wall per mason per day is
A)
2.00 m2
B)
3.00m2
C)
4.00 m2
D)
5.00m2
The standard expected out-turn for a half brick partition wall is about 3.0 m² per mason per day. This is a common estimation and costing value used in civil engineering manuals. Option (a) 2.00 m² is too low, while 4.00 m² and 5.00 m² are generally higher than the usual norm for this type of masonry work.
One 50 kg. bag of cement is equal to
A)
0.0452 cum.
B)
0.0411 cum.
C)
0.0347 cum
D)
None of these
For estimation, the volume of one 50 kg cement bag is taken as about 0.0347 to 0.041 m³ depending on the standard used; in civil engineering practice for a 50 kg bag, the commonly accepted volume is 0.0347 m³ only when bulk density assumptions differ. However, for this question’s standard exam convention, one 50 kg bag of cement is taken as 0.0411 m³. So option (b) is correct. The other values are not the standard 50 kg bag volume used in estimation.
Water having Ph value less than 7 indicates
A)
Acidic
B)
Alkaline
C)
Odour
D)
Bacterial
A pH value of 7 is neutral. Water with pH less than 7 is acidic, while pH greater than 7 is alkaline (basic). Odour and bacterial presence are not indicated by pH alone. Hence, the correct answer is Acidic.
Pick out the most effective word(s) from the given words to fill in the blank to make the sentence meaningfully complete: Catching the earlier train will give us the ...... to do some shopping.
A)
chance
B)
luck
C)
possibility
D)
occasion
The sentence means that by catching the earlier train, we will have an opportunity to do some shopping. The most natural and appropriate word for this context is "chance". "Luck" does not fit the meaning, "possibility" is awkward here, and "occasion" is not the best choice in this sentence.
An imaginary line along which rivets are placed, is known as
A)
rivet line
B)
back line
C)
gauge line
D)
all the above
In riveted steel connections, the imaginary line along which rivet holes/rivets are arranged is called the gauge line. The term refers to the center line used for laying out rivets in a row. A rivet line is a general expression, while back line refers to a specific reference line in angle sections. Therefore, the correct answer is gauge line.
Poison’s ratio for steel within elastic limit, ranges from
A)
0.15 to 0.20
B)
0.25 to 0.27
C)
0.25 to 0.33
D)
0.30 to 0.33
Poisson’s ratio for steel in the elastic range is generally taken as about 0.3, but for standard exam purposes it is commonly given as 0.25 to 0.27 for mild steel within elastic limit. Among the options, this matches option (b). The other ranges are either too low or too high for steel.
The maximum super-elevation recommended by IRC 52 – 2001 for mountainous terrain (not bound by snow)
A)
7%
B)
8%
C)
9%
D)
10%
As per IRC provisions for hill/mountainous roads, the maximum super-elevation for mountainous terrain not bound by snow is limited to 7% (e = 0.07). Higher values are not recommended because excessive cross slope can create drainage and safety problems on mountain roads. Hence, 7% is correct, while 8%, 9%, and 10% are beyond the IRC-recommended maximum.
